### Overview and Performance

This has been a successful period of growth and diversification, with the Company entering two new grids and holding a uniquely diversified portfolio of 1.17 GW across five uncorrelated markets. These assets achieved strong growth and an attractive dividend yield for our investors, with a NAV total return of 12.3% and 7.5p in dividends declared for the period. The dividend for the year, based on the 31 March closing share price of 100.8p, was equivalent to a 6.9% yield. Over the five years since our IPO, the Company has delivered a NAV total return of 48%, including 29p of dividends paid to Shareholders. With 291.6 MW of operational capacity in the portfolio thus far, the last financial year laid the foundations for a sustained period of growth and opportunity for our portfolio. Over 500 MW of capacity is scheduled to come online by the end of 2024 across the Company’s portfolio, including in California, where the 200 MW Big Rock asset will establish us in a new market, the CAISO grid. During the reporting period, the Company generated an average revenue of £135,000 per MW/yr, resulting in total revenue of £39.3 million. Post-reporting period, the Company successfully expanded the existing GBP 15 million revolving debt facility with Santander to GBP 50 million together with an accordion option.

In 2018 we identified the vulnerability of relying on a single market and the volatility it introduced to our revenues and overall profitability. We made our first international acquisition in 2019 on the all-Irish Grid, where we now have a fleet of assets totalling 310 MW, of which 130 MW is operational.

During the reporting period, the contributions from our Irish assets have been significant, generating the largest proportion of revenue for the Company. Our Irish assets boast a duration of sub-30 minutes (and therefore the lowest capital expenditure within our portfolio and significantly below the market average), which is optimally sized to capitalise on the available contracts on this grid. Moreover, these assets have consistently over delivered and now surpass the level of revenue we see in the GB market.

Expanding our operations into new geographies required extensive efforts to navigate the regulatory landscapes, establish networks, and understand the contracts available with each grid operator. While pursuing a GB-only strategy could have expedited deployment and led to a larger operational asset base today, 2023 has shown us that this would not have been the correct approach. By pursuing an internationally diversified strategy, the Company hasn’t been wholly exposed to a grid with currently declining revenues, as opposed to the diversified fleet of assets we currently possess, which continues to deliver industry-leading returns for our investors.

The Company remains well-capitalised to meet all contractual obligations over the next 12 months without further debt. The Company maintains a gearing level of less than 5% of NAV. This aspect is significant, differentiating the Company and insulating it from increased debt servicing costs.

Over the next period, we aim to introduce a conservative level of debt. Accounting for the construction funding requirements for the 522 MW of capacity targeting energisation by end of December 2024 and milestone payments for assets targeting energisation after this period, net debt is expected to stay below £150m or 21% of GAV over the 18 months from the date of publication. Considering the prevailing cost of debt and the recent interest rate hikes, I believe this is the appropriate approach.

During the period, the Company continued to execute on its growth strategy, both in terms of capacity and geographical diversification. This first led to the successful acquisition of three operational assets and four pre-construction assets in the ERCOT market of Texas in April 2022, with a combined capacity of 69.65 MW, which was later followed in January 2023 with the acquisition of the 75 MW Dog Fish asset in the State. The Company continued this momentum in February 2023 by entering a fifth grid market with the completion of the acquisition of Big Rock, a 200 MW/400 MWh asset located in California.

DIAGNOSTIC BRANDS

![img-1.jpeg](img-1.jpeg)

The Company made one of its largest investments to date with the 200 MW Middleton project, which will be built in the north of England. Together these project additions have taken the Company's portfolio to a capacity of 1.17 GW spread across five distinct energy systems, with access to more uncorrelated revenue streams than ever before.

## Macroeconomic Environment

There have been considerable macroeconomic shifts in the reporting period – ranging from rising short-term inflation and interest rates to increasing construction costs – due, in part, to the unprecedented financial market conditions that have developed over the financial year. Our Investment Manager has demonstrated sound risk management and resilience within this context, adopting effective measures to mitigate their impact on the portfolio.

Through its dedicated construction team, we have secured competitively priced engineering, procurement, and construction (EPC) contracts, leveraging pre-established relationships and economies of scale, given the size of the Company's construction portfolio. The Company has also benefited from minimal debt exposure, insulating it from increased debt servicing costs, while our unique diversification has proven valuable in creating natural hedges against FX volatility and pricing movements experienced in the GB market.

Despite these conditions, the fundamental growth drivers for energy storage remain strong, driven by the worldwide transition to low-carbon energy generation and further reinforced by the global concern over energy security. We remain confident in the Company's ability to deliver sustainable dividends and attractive capital growth for our investors over the long term.

## Dividends

The Board has approved a fourth interim dividend of 1.5 pence per share, bringing the total dividend announced for the period ending 31 March 2023, to 7.5 pence per share, in line with the Company's progressive Dividend Policy. The dividend paid for the year based on the 31 March 2023 closing share price of 100.8p was equivalent to a 6.9% yield.

## NAV Performance

NAV has continued to progress in line with the Company's target returns increasing from 109.1p per share in March 2022 to 115.6p per share as of 31 March 2023, reflecting a NAV Total Return of 12.3% for the reporting period. With a significant portion of the portfolio under construction (c. 75% on a MW basis), we maintain a positive outlook on our ability to continue to deliver long-term value to our shareholders as we deploy operational capacity over the next period and beyond.

As we progress with the build-out of our construction portfolio, we expect further positive impacts on revenue generation, dividend coverage, and enhanced shareholder value as projects are de-risked and revalued from stages of construction to becoming operational.

## Discount Management

In the interest of discount management, at the Board's discretion, the Company is able to repurchase its shares at a price lower than Net Asset Value (NAV). However, as the Company's funds are fully committed to the build-out of the portfolio assets, and the healthy returns available, we do not believe this to be the optimal course of action. The Board will diligently monitor the performance of the share price and retains the ability to employ appropriate discount control mechanisms if deemed necessary.

Annual Report for year ended 31 March 2023 3
Strategic Report

## Strategy and Operational Performance

Our strategy in FY 2022/23 continued to be led by participation in various ancillary services, which remain the most profitable source of income available to energy storage assets. The portfolio engaged in some wholesale trading opportunities when appropriate but achieved 93% of total revenue from ancillary services, emphasising the significance of these services in the revenue stack and highlighting the effectiveness of our system duration in the GB market.

The GB portfolio performed well in the first half of the reporting period, driven by our success in FFR services and the introduction of Dynamic Services. High revenues from DS3 ancillary services in Ireland, resulting from increased renewable generation in winter months, helped offset the impact of declining prices witnessed in GB during the second half of the financial year. This seasonal volatility underscores the value of our portfolio operating across multiple grids and geographies, reducing our exposure to revenue fluctuations in any single market.

Similar patterns of seasonal performance were seen in Germany, where our newly acquired asset was called on to help tackle the sustained volatility experienced over the summer months as gas prices peaked. August provided the highest monthly revenue from the ancillary services market, with prices remaining stable throughout winter.

The summer also proved beneficial for the Company's operational assets in Texas, where several extreme weather events, including a heat wave in July 2022, caused ancillary services prices to spike above $2,000 (£1,590)/MW/hr as demand increased. A similar impact was seen in December 2022, resulting from a winter storm, which drove prices even higher.

This volatility in summer and winter, separated by subdued pricing in the transitional seasons of spring and autumn, can be seen broadly across the portfolio and illustrates the value of having assets located across multiple grids to capitalise on extreme swings in supply and demand.

## Sustainability

Over the past 12 months, we have continued to build on our commitments around how we record and report the Company's impact. The Company's first ESG & Sustainability report, published in August 2022 for the previous reporting period, delivered voluntary disclosures for our GB and Ireland assets covering emissions, social metrics and efforts to understand the human rights exposure of our supply chain. We have ramped up these efforts during the reporting period and expanded our reporting to cover Germany, Texas and California, where we added assets in early 2022.

An SFDR Article 8 periodic report covering Principle Adverse Impacts (PAIs) is disclosed in this report. This will be followed in August 2023 by the Company's second ESG & Sustainability Report, which will include reporting under the Sustainable Finance Disclosure Regulation (SFDR) and the Task Force for Climate-related Financial Disclosures (TCFD) disclosures.

## Debt

Post-reporting period, the Company successfully expanded the existing £15 million GBP revolving debt facility with Santander to £50 million. The facility includes an accordion option to increase beyond £50m to up to 30% of Gross Asset Value. Pricing for the £50m facility remains unchanged at 300 basis points over SONIA. Throughout the calendar year, we will remain focused on optimising the Company's capital structure and are actively exploring debt options in both GBP and USD.

The recent acquisition of the Big Rock project in California presents an opportunity for project level financing by leveraging its unique revenue profile under the Resource Adequacy mechanism. This programme has similarities to GB's Capacity Market in that it aims to ensure safe and reliable operation of the grid through security of supply but can offer up to 40% of revenue under a long-term contract. This level of secured revenue allows us to consider asset-level debt financing in a new way, further supporting the Company's decision to diversify its portfolio.

## Board Composition and Succession Planning

In the 2022 half-year report, I updated shareholders on our progress with the recruitment of a new Director. We are delighted to welcome Lisa Scenna to the Board, effective 1 May 2023. Lisa's skills and experience are detailed on page 49 and she will be standing for election at the AGM with the rest of the Board.

The remuneration and nomination committee also recommended that the Board seek to appoint a new Director in 2024/25 and every two or three years thereafter, such that Directors' retirement dates are staggered as part of orderly succession planning.

## AGM and Continuation Vote

This year marks an important milestone for the Company, as it passed its five-year anniversary. When the Company's shares started trading on 25 May 2018, it was the first listed company offering access to energy storage.

Five years later, the Company has built an internationally diversified portfolio of 1.17 GW and delivered a NAV total return of 48%, including 29p of dividends paid to Shareholders.

# Market Overview

## Summary

The world is experiencing unparalleled transition to a cleaner, more secure energy system through the widespread adoption of renewable energy sources. Generation from utility scale wind turbines, solar panels and other distributed renewable energy resources is rapidly decarbonising global power grids with inherently intermittent output, leading to higher volatility on energy grids. The ability to effectively capture, store and discharge energy when it is most needed has become a critical tool in successfully integrating clean power generation, improving the efficiency of energy systems and reducing the world's reliance on polluting fossil fuels.

New urgency has emerged within the low carbon energy transition following Russia's ongoing invasion of Ukraine, which has exposed several markets' overreliance on fossil fuels. Shortages of oil and gas, combined with increased episodes of extreme weather, have caused energy prices to spike as demand outstripped supply.

Energy storage owners are well placed to provide grid operators with the flexibility they need to reduce these imbalances between energy demand and supply by supporting them to reduce system volatility. This improves energy security to maintain the electricity grid system at the correct frequency and keep the lights on while ensuring the global move towards decarbonisation can continue at pace. The faster these flexible renewable energy solutions can be deployed, the faster society can move to a more sustainable world.

As a global owner of large-scale energy storage assets working in five grids (Great Britain, Ireland, Germany, ERCOT in Texas and CAISO in California), the Company is delivering these benefits in multiple jurisdictions. This internationally diversified approach means the Company's operational assets – online in four uncorrelated markets to date – can utilise the dynamic and flexible capabilities of energy storage technology to stack revenue streams across contracted and merchant opportunities.

The majority (72%) of the Company's 291.6 MW operational portfolio benefit from Capacity Market (CM) contracts which allow merchant revenues to be stacked around secure income. The remaining capacity (28%) operates on a purely merchant basis, adding further diversity to our revenues. This allows the entirety of the portfolio to counteract any quarterly downturns or volatility experienced in specific markets throughout the year and maintain healthy returns for the Company and its shareholders.

Ancillary services continued to represent the majority of revenues for all energy storage assets in fiscal year (FY) 2022/23, which saw National Grid ESO unveil a full suite of new frequency response services. Dynamic Regulation (DR) was launched in April 2022, after a testing phase in Q4 2021, followed by Dynamic Moderation (DM) in May 2022. They were introduced with the aim of retiring services such as Firm Frequency Response (FFR), in which energy storage had widely participated in previous years. FFR was intended to be phased out within FY 2022/23 but has continued largely due to uncertainty and the extension of the trial period for new services (DM and DR). With a view to duration across the period, the majority of uncontracted revenue came from FFR or DC (Dynamic Containment) which both can be provided by sub-one and one-hour systems. Whilst DR was the most profitable in the period, it was capped at 100 MW, creating a small opportunity for systems over 1.5 hours.

National Grid ESO began to procure higher volumes of the previously introduced DC over the summer in 2022 and increased the price cap for the DC product alongside the gradual introduction of DR. Removal of the initial £17/MW/h price cap, combined with DR and procurement volumes required by National Grid ESO exceeding the supply-side capacity of energy storage in GB, allowed participants to push DC clearing prices upwards to the benefit of the entire market.

H2 of the reporting period was marked by a fall in D-suite (DC, DM, DR) prices caused by market saturation, particularly towards the end of the period when additional capacity in the GB market came online.

As FFR and D-suite services are mutually exclusive for a given period, this downward price trend – which continued into March 2023 –
made FFR one of the most lucrative services for energy storage in the Autumn and Winter of 2022/23 as market participants priced in
the opportunity cost of D-suite and wholesale trading into their FFR bids, which National Grid accepted.
The opportunity cost for FFR bid prices is calculated to encompass the estimated monthly revenue from the alternative revenue stack.
As a result, D-suite revenues are more sensitive to the daily market grid and market dynamics such as National Grid ESO buy curves,
demand, electricity prices, and renewable penetration. D-suite clearing prices remain uncertain and, therefore, more volatile.
Procurement volumes of FFR were reduced towards the end of FY 2022/23 as part of the electricity transmission system operator’s
phase-out of FFR, driving increased competition as the market sought guaranteed monthly revenue rather than risk exposure to daily
volatility in D-suite procurement auctions. The low perceived opportunity in DC and decreasing procurement volumes dragged FFR
prices down.
DR volume caps, meanwhile, were raised from 100 MW to 200 MW as of March 2023 to accommodate more consistent use of this
service by National Grid. DR has a lower frequency deviation trigger, requiring more battery cycling than DC and assets below two-
hours duration to de-rate their capacity to participate in the market. The additional strain led to fewer participants entering DR in the
initial period, creating lucrative opportunities for participants qualified to enter this market. While DR has not been immune to the
downturn in revenues seen with DC, as more energy storage has qualified for delivery, it continues to clear on average higher than DC,
reflecting the additional opportunity cost.
DM volumes have remained capped at 100 MW, as National Grid ESO does not systematically acquire DM volumes.

Non-synchronous generation in the Irish market, led by wind power, has been a key resource in efforts to achieve a 100% renewable
energy system and has created a market for ancillary services through the DS3 (Delivering a Secure Sustainable Electricity System)
programme. Energy storage investment has been encouraged via procurement through uncapped (annually procured) and capped (up
to six-year contracts auctioned in 2019) schemes.
Uncapped contracts unit price is based on System Non- Synchronous Penetration (SNSP), which refers to the real-time measure
of intermittent renewable generation on the system and net interconnector flows within the single electricity market. Revenue is
calculated based on annual fixed tariffs multiplied by various scalars including availability and SNSP, the principal factor driving
volatility in DS3 revenues. This is predominantly set by wind penetration levels, which represent the largest deployed renewable
generation resource in both Irish grids. There is a direct correlation between SNSP levels and DS3 uncapped revenue, which fluctuates
with seasonal variation to provide higher financial returns during the peak winter months. In contrast, summer revenues have not
reached the same levels as these months typically experience fewer windy days and are not pushed higher by the amount of solar
generation in the market.
In contrast, capped contracts are fixed at the contracted price. SNSP scalars, which provide a multiplier for the uncapped tariff
(common across the Irish DS3 uncapped market), experience seasonal variations.

Germany comprises four transmission system operators (TSO) in a single grid, each controlling an area of the country. The Company currently interacts with the TSO 50Hertz by providing Frequency (Primary) Control Reserve (FCR). This cross-border service operates across eleven transmission system operators in eight European countries, with 50Hertz and other German TSO able to pass on excess flexibility to the wider European grid. FCR in Germany has typically been delivered through gas as the biggest provider of generation, meaning power prices generally mirror seasonal variation in the wholesale gas market. This usually results in lower prices during summer and higher in winter when demand for gas and electricity is higher.

As illustrated in the graph below, power prices increased sharply towards the end of 2021 to accommodate rising demand across the EU as countries recovered from the economic impact of the Covid-19 pandemic.

Electricity prices continued to increase in line with gas in April 2022 following the Russian invasion of Ukraine, which impacted energy supplies and gas storage in continental Europe, as shown in figures 4 and 5. The resulting shortage in supply across Europe during the reporting period drove gas prices and the marginal cost of power production from gas-fired power plants up in the summer. Over 2022 Germany paid more than double for its natural gas imports compared to the previous year, according to the Federal Office for Economic Affairs and Export Control, BAFA1, which, in turn, caused FCR prices to surge.

Figure 4: FCR vs electricity power price trends

![img-2.jpeg](img-2.jpeg)

The trend of increasing prices reached a record high of €469/MWh in August 2022 when extreme summer temperatures impacted hydropower generation due to low water levels. It even contributed to low nuclear capacity in France due to low reservoir levels reducing water available for cooling reactors$^{3}$.

As the EU entered the Autumn period, wholesale prices started to decrease due to milder weather, which led to lower demand, and higher gas storage availability after the EU implemented a regulation requiring all storage facilities on the continent to be filled to 80%, on average, before the winter of 2022/2023. This was achieved in late August using LNG imports from the US$^{4}$ and caused FCR prices to fall faster than seen in previous years.

The factors of: Covid-19 recovery, worldwide gas volatility caused by war in Europe, and extreme temperatures experienced across the mainland created an abnormal seasonal variation during the period, where FCR was higher in the summer and lower in the winter. Prices stayed higher than the previous year, however, with the average natural gas import price in December – equivalent to €9.38/kWh – remaining 74% above a year earlier, following a period of divestment from Russian supplies.

Additional revenue for short-duration flexibility is now available through automatic Frequency Restoration Reserve (aFRR), also known as Secondary Control Reserve, following a reduction in delivery duration from four hours to 15 minutes. This service is designed to support FCR should it fail to deliver the flexibility needed to maintain the grid by maintaining a reserve in the power grid that helps to keep the grid frequency stable. This provides revenue for availability in case of activation and for actively balancing energy when called on.

This reporting period also provided opportunities in wholesale trading across the FCR market, with liquidity available from the demand for balancing from renewable generators seeking to settle their supply imbalances before facing high system charges.

US President Joe Biden signed the Inflation Reduction Act into law on 16 August 2022. The legislation provides $369bn over ten years to tackle climate change and invest in the renewable energy sector to reduce carbon emissions by 40% by 2030, compared with 2005 levels.

Two-thirds of this funding will be used to extend or introduce support for emission-free electricity generation and storage technologies.

Standalone utility-energy storage projects with a minimum name plate capacity of 5 kWh can now access investment tax credits (ITCs) worth at least 30% of capital expenditure for the first time provided construction is underway by the end of 2024. Projects beginning construction in 2025 through to 2032 will be able to receive ITC support however specific facilities will be done on a technology neutral basis. Per the 2022 unemployment data published by the Bureau of Labour and Statistics (BLS), the Company's assets: Dogfish, Wichita Falls, and Mineral Wells (combined 95MW) all qualify for 40% ITC, provided that unemployment rates in these regions remain equal to or higher than the national average.

5
(ERCOT) and 25 GW (CAISO) more in construction or planned .
Ancillary services are the main revenue driver in ERCOT, except when extreme weather events create opportunities in wholesale
markets as real-time prices spike due to swings in supply and demand. These weather events also impact ancillary services and can
produce price spikes and supply scarcity, driving demand for Responsive Reserve Service (RRS).
The Company expanded the number of services offered after the reporting period to include existing (e.g. Regulation Up/Down) and
new (e.g. ECRS – Contingency Reserve Service) revenue streams. The wholesale market opportunity was and continues to be bearish,
mainly due to falling natural gas prices. This trend is expected to reverse throughout 2023 and into 2024 in line with commodity
prices and demand increases.

Target energisation Dec-end 2024
The outlook for ancillary services in California’s CAISO market is well supported by three main fundamentals: grid flexibility, high
penetration of non-dispatchable renewable generation and decommissioning of existing conventional generation. Deployment of
battery storage is integral to increasing penetration of renewable energy as existing conventional energy resources are unable to meet
sub-second response requirements. This need for flexible capacity has seen a rapid deployment of battery energy storage systems
motivated by the retirement of fossil fuel generation. CAISO experiences a similar frequency of extreme weather events as ERCOT
despite its location on the opposite coastline – these events create short-term spikes in wholesale and ancillary markets.
In addition to ERCOT, the Inflation Reduction Act applies in CAISO and will give access to an ITC worth at least 30% of capital
expenditure, which can be extended to some Tax Credit Adders for projects in low-moderate income communities, tribal lands, or
repurposed fossil fuel power plants to between 2% and 20% extra per individual possible adder.
Revenue opportunities under the Resource Adequacy (RA) mechanism, which acts as a tool for CAISO and the Local Regulatory
Authorities to ensure enough generation capacity is secured ahead of time to deliver security of supply, are also drivers. RA can be
compared to the Capacity Market in GB in that it offers secure revenue on which the prevailing ancillary/wholesale merchant strategy
can be stacked. They differ, however, in that RA contracts are expected to represent up to 40% of the revenue of a battery energy
storage system, a materially higher proportion than GBs CM contracts account for.

# Revenue Generation and Portfolio Performance

The Company exercised a diverse strategy throughout the reporting period, participating in a mixture of ancillary and trading opportunities across the markets in which it is active. Revenue was generated from a growing suite of services launched in 2022 (e.g. the expanded D-suite in GB), while the Company also implemented steps to prepare for additional streams in 2023 (e.g. wholesale trading in Germany) and post-period (e.g. ECRS in ERCOT).

## Great Britain (GB) market

Ancillary services played a key role in GB revenue generation, accounting for 85.7% of annual revenue, or £13m. The strategy for bidding into varying ancillary services was evaluated in advance as FFR is bid into one month before delivery to secure calendar-month-long agreements. D-suite services, meanwhile, are bid into on a day-ahead basis and provided an alternative strategy.

While all the assets were entered into FFR for all EFA blocks at various points throughout the financial year, a higher bid strategy was adopted for those more suited to delivering for the DC market. This meant they were available to pick up FFR contracts if prices reach a higher bid level but, in most months, meant they could ensure an even split between FFR committed capacity and DC committed capacity was achieved. This diversified services strategy acted as a hedge against the volatile conditions experienced earlier in the year.

Revenue in Q1 2022 was the highest of all reported quarters since April 2021 and was 40% above the previous year's Q1 revenue. This was largely due to the uplift in DC prices across this period, with DC representing 51% of all revenues achieved (Capacity Market included). The continued uplift in D-suite revenues also led to Q2 2022 being 18% ahead of the previous year, with D-suite representing 73% of all revenues.

Lower prices were bid into FFR in H2 of the reporting period due to fewer alternative opportunities in the D-suite market caused by market saturation. H2's performance was 35.5% below the previous year, in stark contrast to the excellent market conditions in H1. Whilst FFR prices cleared higher than DC and DM, on average, decreased procurement volumes ahead of retiring the service (contributing to increased competition) led to fewer batteries in the portfolio receiving contracts. FFR represented only 31% of revenue in H2, although the portfolio saw an increase in trading, which accounted for 11% of revenues during the same period.

FY 2022/23 included the second half of the 2021/22 Capacity Market delivery year and the first half of the 2022/23 delivery year. Capacity Market revenue in H2 was 31% above H1, driven in large part by the £75/kW clearing price of the 2022/23 T-1 Auction; the Port of Tilbury (POTL) asset secured a contract at 7.061 MW de-rated capacity. Capacity Market revenues represented 8.9% of the GB portfolio revenues during the financial year.

## Irish market

### Northern Ireland

Ancillary services, monetised through DS3 uncapped contracts, generated 98% of revenues for the Northern Irish fleet, totalling £15.5m across the financial year – an uplift of 27% of total revenue compared with the previous financial year. DS3 uncapped tariffs for each of the five contracted ancillary services are subject to yearly variations by the Regulatory Authority in Ireland and could inevitably lead to lower revenues being secured. Despite a 10% reduction in DS3 tariffs in January 2022, the NI portfolio still generated 24% more revenue from DS3 this financial year, driven mainly by increased SNSP levels in the December-end quarter. Monthly DS3 uncapped revenues peaked in FY 2022/23 at £29.24/MW/h, just short of the all-time high of c. £33.87/MW/h in February 2022.

The remaining 2% of the revenue stack comprised two revenue streams: Capacity Market and wholesale trading. The contracted Capacity Market revenue generated around £36,000 per month in total from both assets, starting from October 2022 and continuing post-period until the contracts end in September 2023. The NI portfolio also secured yearly Capacity Market contracts until September 2027.

Trading remains in its infancy in the grid with limited accessibility to the wholesale market. To date, bids from the NI assets have been accepted to dispatch volume generating c. £118,000.

## Republic of Ireland

Porterstown Phase I operates under a six-year DS3 capped contract (starting September 2021) with a fixed tariff rate of €6.79/MW/hr. The asset was declared available to provide services on 24 January 2023 and has since generated €326,000 throughout the remainder of the March-end quarter. Prior to the DS3 capped contract, the asset generated additional revenue from liquidated damages caused by delays experienced by the engineering, procurement, and construction (EPC) contractor in delivering the project.

The NI & ROI portfolio generated an overall average weighted price of £14.93/MW/h, with the bulk of the revenue generated from DS3 uncapped revenue.

## German market

The Company acquired the Cremzow project at the end of the previous fiscal year with a view to targeting ancillary services in a new market that presented similar conditions to GB. The asset enabled the Company to capitalise on uncharacteristic price rises in gas, power and ancillary markets during the summer of 2022.

Delivery of ancillary services resulted in revenues totalling €3.7m through provision of FCR for 98.0% of the year, with monthly revenue accrued directly from FCR peaking at €32.22/MW/h in August to achieve a total of €488,000 – the highest monthly revenue in FY 2022/23, marginally ahead of October 2022.

FCR prices remained stable during the winter months, once again moving against expected seasonal variation where previously prices would increase towards the end of the calendar year. The stability at lower levels pushed the Company towards expansion into new revenue streams, mainly the wholesale market.

The Company expanded its capabilities in Germany to include wholesale trading through work with a new optimiser and, in March 2023, generated revenue of €73,400 solely from wholesale trading following delays transitioning to a new FCR provider and pending approval from 50 Hertz. Post-period, the Company's revenues will be a blend of both streams with the expected addition of aFRR following submittal of tests for post-period evaluation to join the service.

## Texas (ERCOT market)

Due to the significant renewable energy development in this region and unique characteristics surrounding interconnections, there is exposure to wholesale price volatility due to the inherent intermittency of renewable generation. This isolation of the ERCOT grid means there is an increasing need for flexibility. The Company's activity this period, however, was focused on performing RRS, which is also affected by swings in renewable supplies.

Several extreme weather events during FY 2022/23, such as a heat wave in July 2022, caused RRS prices to spike above $2,000/MW/h for a short period. This occurrence was not isolated, with a similar scenario in December 2022 resulting from a winter storm and cold snap driving prices up to $3,000/MW/h. These short-term events resulted in monthly revenue of $57.26/MW/h in July and $36.12/MW/h in December.

Such events related to weather conditions are more likely to occur during winter and summer, leaving spring and autumn as transition seasons, typically referred to as shoulder months. In ERCOT, steady wind and thermal generation led to lower prices in RRS during the March-end quarter; consequently, the Company's revenue dipped to $4.51/MW/h. The seasonal price volatility captured by the ERCOT assets during extreme weather events versus shoulder months are an expected market condition of operating in ERCOT and offset the fall in revenue experienced during transition periods of the year.

Strategic Report
The charts below highlight the seasonal variation in each market and how the Company’s diverse portfolio results in exposure to
lucrative opportunities when one market is experiencing a downturn. As detailed above, saturation in the GB ancillary market drove
clearing prices down at the same time as a pickup in the Irish market. While the overall result was lower year-on-year fleet revenue in
the March-end quarter, the impact would have been more significant if the portfolio had been solely exposed to the price decline in
GB.

### Operational
The operational assets (weighted by asset capacity in MW) achieved over 95% availability during the year. This excellent performance
was supported by the increased availability of the GB portfolio and a successful operational takeover of the Porterstown asset in
Ireland.
Great Britain: The overall availability for the GB fleet was positive, highlighting successful interventions by the Commercial Manager
and management of O&M contracts over the year. The latter half of the year showed a c. 5% increase in weighted average availability to
94% (from 89% in H1 2022), driven predominantly by improvements at Boulby, Port of Tilbury and Larport. The only asset with material
reductions in availability in the latter half of the year was Ancala due to various project issues requiring repairs that are now resolved and
where downtime is subject to liquidated damages under availability guarantees.
Ireland: Portfolio performance in Ireland (and Northern Ireland) remains a highlight, with weighted availability (by MW capacity)
of 99% over the reporting period between the three Irish projects. The Company saw its first asset in the Republic of Ireland,
Porterstown, enter operations in January 2023. To date, there have been no availability reductions with the asset. The Northern Irish
assets—Drumkee and Mullavilly—continue to meet performance expectations and achieved 97% and 99% availability over the year,
respectively. Availability was impacted by quickly resolved inverter failures. The O&M provider is providing additional training with the
supplier to further improve repair times in future.
DS3 services provide most of the revenue for all three operational Irish projects. In the reporting period, all DS3 events—instances
where grid frequency drops below 49.8Hz and asset response is assessed by the system operator— recorded on the Irish network
were successfully delivered and each project was monetised successfully. The Commercial Manager’s improvements to the technical
response of the assets addressed issues seen during the previous financial year, highlighting the benefit of the Commercial Manager’s
experienced technical team managing the assets.

DMDC DR FFR
Strategic Report
Germany: The Cremzow project is generally performing well. In July 2022, an inverter issue with the 2 MW proportion of the project
impacted availability but was resolved in a timely manner. Availability impacts were infrequent and isolated over the year, limiting the impact
through timely successful maintenance activities and active engagement by the Commercial Manager. The asset recorded 96% availability
over the reporting period and there are no ongoing concerns, with availability expected to remain high.
US - Texas: The three operational assets—Snyder, Sweetwater and Westover—performed well during the period. Technical
performance was good across the 9.95 MW projects, and their total availability averaged over 95%. The most notable availability
impact was a commercial restriction at Westover due to miscommunication between the optimiser and the Texas system operator
ERCOT, resulting in lower availability in October 2022 (no ongoing concern). System inverter issues were observed with limited
availability impacts on each occurrence, and the Investment Manager opted to make preventative improvements to all inverters, which
drove availability reductions in H2 2022 but are expected to improve availability over the longer term.

### Asset management developments
It was an exciting year for energy storage, particularly for operations of the Company’s portfolio. The Investment Manager successfully
onboarded assets on two new transmission networks: in Germany and Texas. The over 95% availability on each of these grids
demonstrated the team’s ability to quickly build and manage relationships with new contractors despite the expansion into new
territories.
The Investment Manager’s in-house technical team grew substantially over the period and drove important initiatives for the Company’s
operational assets and pipeline. The first retrofit of an electrolyte vapour detection system—used to prevent the operation of batteries in
scenarios which may lead to thermal runaway—was completed for the Cremzow project in Germany. Security enhancements have been
made to reduce the risk of thefts, enhance safety performance (through monitoring and visibility) and gave the team better engagement
with on-site activities. Trials have begun with industry-leading analytics partners to further improve performance through state of charge
and state of health prediction improvements whilst materially improving safety through ‘risk reduction by prevention’ measures. The
continuation of this workstream is set to be a key focus in 2023.
The Company continues to build key relationships whilst developing contractual partnerships suited to the portfolio’s increasing
capacity. The Investment Manager’s increasing technical capability is delivering important initiatives (such as those referenced above)
whilst improving the delivery of the team’s most core requirements. This is evidenced by the materially improved availability figures
reported over the entire reporting period relative to the H1 2022 period reported in the Company’s most recent Interim Report.
### Portfolio
Construction/pre-construction
514.8 MW of construction or pre-construction phase assets were acquired during the reporting period, bringing the total pre-
operational capacity to 881.6 MW.
Given the macro environment and future capital expenditure projections, the Investment Manager has made a decision to optimise
asset build out based on targeted energisation date and capacity. The Investment Manager strategically decided to prioritise the
following assets: Stony, Ferrymuir, and Enderby in GB; Big Rock in California; Porterstown II expansion in Ireland; and Dogfish in Texas
(a total of 521.8 MW). In the near term, the Investment Manager will prioritise larger assets over the 9.95 MW sites in Texas while
exploring opportunities to increase their capacity, similar to the expansion projects announced for the Company’s Irish assets.
In Great Britain, commissioning of Stony (79.9 MW) has commenced and the energisation process will begin at the end of July, while
Ferrymuir (49.9 MW) is at the final stages of mechanical completion, with the majority of contestable works completed. The asset
is waiting for energisation of the grid connection by the distribution network operator, expected in summer 2023. Works at Enderby
(57MW) are underway but have been impacted by National Grid ESO’s outage availability resulting in a consequent delay to energisation.
National Grid ESO has advised that April 2024 is the next available outage window during which their works can be completed and,
subsequently, the asset can be energised.
### 22 Gore Street Energy Storage Fund plc
Strategic Report
In Ireland, Porterstown Phase II (60MW) consents have been acquired, with design and procurement underway. Modifications to the
connection agreement have been negotiated with EirGrid to enable the connection of the extension, and energisation and commissioning
are expected in June-end 2024.
In California, the Big Rock (200 MW) project acquired in February 2023 is progressing well, with batteries and grid transformers
delivered and in storage. The procurement of the key balance of plant contracts is near completion, with mobilisation planned for
August 2023. Permitting and grid consenting are underway. Enclosures arrive in Spring 2024, and energisation is scheduled for
December-end 2024.
In Texas, Dogfish (75 MW) procurement is underway, with orders of long lead HV plant in advanced stage of negotiations. The grid
connection agreement with the transmission operator (Texas New Mexico Power) has been signed with design works underway.
At Kilmannock, the property purchase option has been exercised. Preliminary engineering and demonstrating planning condition compliance
is underway for Phase I (30MW), while Kilmannock Phase II (90MW) has received and accepted its connection offer. Optimisation of
the design and configuration of the grid connection plant for phase I and II is underway, however, the delivery of the project has been
deprioritised to optimise capital deployment.

# **Q: How do you see dividend cover evolving over the next two years?**

The Company generated cash flow$^{7}$ of 6p per share which translates into 4.8% cash yield per NAV or 5.5% cash yield per share price as at 31 March 2023. The Company's dividend yield was 6.9% based on the 31 March 2023 closing share price.

The Company is following a strategy of acquiring assets at the project rights stage and constructing them utilising in-house technical expertise. This enables energy storage system procurement at competitive costs and flexible battery system design to accommodate future market uncertainty. In addition, rather than taking a simple approach of replicating similar assets in the same grid over and over, the Company entered new geographies to deliver a diversified portfolio with less exposure to single revenue drivers. While this approach requires longer lead times, the superiority of the strategy is evidenced by the cashflow of the operational portfolio, which only accounts for 30% of total NAV and provided an 90%$^{8}$ operational dividend cover, based on dividends paid in the period. On a consolidated fund level, these operational assets provided 0.54x dividend cover for the fund. Given the over 20-year life of energy storage projects, management believes a careful approach to investment and construction is prudent for energy storage.

The Company raised £150 million in April 2022. While this reduced dividend coverage by 26.3%, raising equity capital upfront enabled the Company to gain further financial security without excessive reliance on external debt. It also supported large strategic acquisitions at an attractive price (over 500MW acquired during the reported period).

The Company's ability to cover its dividends through the generation of revenues from its operational asset portfolio undergoes significant change over the Company's lifecycle. Since inception of the fund, we have delivered on our promise to pay a 7% dividend to investors each year, despite our early-stage investments into pre-construction assets which generate cashflows only when operational. Whilst our project-rights acquisition strategy has allowed for industry-leading levels of capex per MW, exceptional capital discipline and a robust foundation for high-performing operational assets, it is a longer-term approach that prioritises growth over dividend cover in the short term. Our strong belief in diversification as a key strategy for success in the storage market meant we focused on entering new geographies. This may have prolonged the timeline for the buildout of our operational portfolio, but we believe the revenues generated across five grids or more will be the necessary basis to manage the merchant volatility and ensure a stable dividend cover.

If revenues were to remain at the current level across each grid, further operational capacity will need to be online to fully cover dividends at both a portfolio and PLC (consolidated) level. Currently, we are at a crucial juncture as a substantial number of assets are poised to become operational in the near future across multiple grids, with 130 MW scheduled to come online in GB over the next six months, and the landmark 200 MW Big Rock project coming online in California 12

$^{7}$ Operational portfolio EBITDA minus holding company operating expenses plus external net interest income

$^{8}$ This figure is based on portfolio EBITDA only and does not include HoldCo or PLC expenses

months after that. This strategic diversification and the upcoming increase in operational capacity will leave us well placed to cover dividends and drive sustainable growth.

# **Q: What is the Company's exposure to each market in which its assets operate?**

The Company's operational portfolio is split across four grids, with 38% in GB, 34% in NI, 10% in ROI, 10% in Texas, and 8% in Germany.

The benefits of the Company's diversification strategy were seen this year in Ireland and Germany, where more lucrative pricing in the first quarter of 2023 offset the subdued pricing seen in GB, keeping the Company's overall revenue stack relatively constant. This is in line with the Company's strategy to be exposed to multiple uncorrelated revenue streams, which is particularly important for a largely merchant asset class.

# **Q: Were available revenues as you expected during the year?**

As expected, seasonal variations played a significant role in revenue generation for the financial year. GB and NI provided the bulk of revenues in Q1, followed by a fall in NI in Q2 caused by low SNSP at the same time as an uptick in Germany and the US.

Portfolio revenues began to dip in Q3 but were supported by a resurgent NI portfolio thanks to higher SNSP caused by more wind. The final quarter weighed heavily on the overall portfolio, with GB revenues 55% lower than the average of the previous three quarters; however, during this time, revenue was highest in NI.

These results highlight the importance of our geographically diversified strategy, further endorsed by market saturation in GB towards the end of 2022 and into 2023.

# **Q: Why delay the construction of assets in Texas, and how do you expect this delay to impact returns?**

As the Investment Manager is responsible for the sustainable delivery of assets for the Company, we continually evaluate the macroeconomic conditions that could impact future capital expenditure. Following the macroeconomic events of the reporting period that resulted in a high interest rate and inflationary environment, the strategic decision was made to optimise the construction schedule of our wider portfolio based on targeted energisation dates and capacity. Prioritising larger assets in GB (Stony, Ferrymuir, and Enderby in GB) and Ireland (Porterstown II expansion), as well as Big Rock in California and Dogfish in Texas, will allow us to bring (a total of 521.8 MW) online while exploring opportunities to increase the capacity of the 9.95 MW sites in the Perfect Power portfolio, as we have done for the Company's Irish assets. We believe this updated construction schedule will reduce overall capital expenditure – the largest cost associated with energy storage assets – and have a positive impact on returns, ultimately increasing value for shareholders.

Cash generation during the reporting period resulted in an uplift of £31m in NAV. An additional £22m uplift was primarily driven
by updated forecasted revenue assumptions for the Company’s international assets during the reported period. In GB, although
the revenue curves saw an uplift in the September-end quarter, this was largely offset by a decrease seen in March-end forecasts.
Revenue curves were revised in line with merchant revenue forecasts received from third-party providers. New Capacity Market
contracts secured across the portfolio, in addition to merchant revenues, resulted in an uplift of £14m in the reported period.
The Manager has adjusted inflation rates and discount rates in response to the current inflationary and high-interest-rate environment
across the portfolio. Changes in inflation rates impacted forecasted revenues and operational expenses, creating a £13m uplift in NAV.
The Manager has updated assets’ discount rates across the portfolio according to their respective grid and operational status. Changes
in discount rates have resulted in a net reduction of £11m in NAV for the reported period.
Other DCF changes and asset depreciation across the portfolio have resulted in a reduction of £23m in NAV. These include changes in
opex and capex pricing, such as battery cell costs for repowering, grid capex, business rates, and EPC pricing.
Acquisitions in the period that sufficiently progressed in their lifecycles were brought to their respective fair values, which resulted in a
£30m uplift in NAV. Cumulatively, Net DCF changes¹ across the portfolio have resulted in a £47m uplift in NAV.

### Revenue forecasts
The Company sources revenue forecasts for uncontracted revenue from independent energy research houses and, where feasible,
adopts an average of multiple independent forecasts to present a more comprehensive view. The Company also considers the advice
of independent consultants and route-to-market providers. This approach has given shareholders visibility on value which has been
proven to be closest to actual revenue generation among listed peers.
Great Britain
GB assets’ valuations are derived from ancillary services, trading, Capacity Market contracts and other revenue sources (such as
TNUoS benefit). All forecasts have been updated using data provided by third-party providers. The price forecasts for ancillary
services and trading are illustrated in the blended curve shown in Figure 20.
During the reported period, the Manager also secured one year T-4 Capacity Market contracts for Hulley, Lascar, Larport, and the
Ancala assets, one 15-year T-4 contract for the Middleton asset and one year T-1 Capacity Market contracts for Port of Tilbury, Stony
and Ferrymuir.
Ireland
Northern Ireland asset valuations use third-party curve averages for all revenue streams and third-party data for DS3 tariffs. Revenues
are derived from the DS3 uncapped regime until 2025 and, from 2026 onwards, use a combination of ancillary services, trading, and
Capacity Market revenue forecasts. The Investment Manager has secured Capacity Market contracts from 2023 to 2027; therefore,
those contracted prices are used to calculate the revenue for those periods.
Republic of Ireland asset valuations use third-party curve averages for ancillary services, trading, and Capacity Market revenue
forecasts. Secured Capacity Market contracts are integrated into the model for the years applicable. DS3 Capped contracts are used
as inputs in the models for relevant assets.
Germany
German asset valuations are derived from FCR revenue assumptions based on the central case of third-party forecasts.
ERCOT
ERCOT asset valuations are derived from the central case of a third-party research house and include revenues from trading and
ancillary services.
CAISO
CAISO asset valuations are derived from the central case of a third-party research house and include revenues from trading and
ancillary services.
Resource Adequacy revenues are based on expected future contracts expected to be secured by the Investment Manager based on
bilateral discussions with load serving entities.

## Inflation

In response to the current inflationary environment, the Investment Manager has revised the CPI assumptions across the portfolio, which now reflect short-term and long-term rates for each grid. These updated assumptions impact both the applicable revenue contracts in place, anticipated inflationary hikes in merchant revenue prices, and increases in operational expenses.

**Table 11**

|  CPI Assumptions | 2023 | 2024 | 2025+  |
| --- | --- | --- | --- |
|  Great Britain | 5.4% | 3.0% | 2.5%  |
|  Europe | 4.8% | 3.0% | 2.5%  |

### Discount rates
The weighted average discount rate across the portfolio increased to 10.1% from 8.3% in 2022. This increase reflects rising interest
rates and supply chain concerns.
Pre-construction and construction phase discount rates are applied depending on construction progress prior to start of commercial
operations and operational phase discount rates are applied once commercial operations have started. The discount rate matrix used
by the Investment Manager is set out below:
Table 12
Discount Rate Matrix Pre-construction phase Construction phase Operational phase
Contracted Income 10.35-10.75% 9.0-10.0% 7.0-9.0%
Uncontracted Income 10.35-10.75% 9.0-10.0% 8.5-9.0%
MW 694.8 186.8 291.6
### Operating expenditures
Notable increases in operating expenses include:
• Business rates: Local councils in GB and NI had set fixed rateable values for properties until revaluations that came into effect in
April 2023, post the reporting period. The increase in business rates resulting from this revaluation was reflected in the GB and NI
portfolio valuations.
• New prices associated with O&M and asset management contracts have been reflected.
### Capital expenditure
Capital-intensive items, such as grid and EPC contracts secured at the project level, were reflected in valuations in line with their
contract prices. Forecasted capital expenditures relating to inverter replacements and battery augmentation (determined by the
degradation profile of the asset) are underwritten using third-party forecasts. Although these reflect higher cell and equipment costs in
the short term, valuations have not been materially affected by these due to the timeframe of these capital works, typically scheduled
to occur between 7-15 years of operation.
The Investment Manager has been assessing EPC contract options for the pre-construction and construction portfolio, specifically
regarding EPC providers and the optimal duration of its projects.
The graph below is illustrative and is based on expected capex costs. Where costs are uncontracted capital expenditures values included in
the graph may be subject to change.

Figure 21 presents the capex to be invested, based on the funding requirements for constructing the 522 MW of capacity targeting energisation by December 2024, and
includes milestone payments for portfolio assets with energisation targets beyond this period. The Company's cash balance as of 31 March 2023 was £123.7m, which is
sufficient to meet all existing contractual obligations.
### 30 Gore Street Energy Storage Fund plc
Strategic Report
The NAV of the Company's construction and pre-construction portfolio, which has been reflected at fair market value, is £376k/MW,
driven by progress in construction work and acquisitions during the period. The construction portfolio refers to Stony (energisation process
scheduled to begin at the end of July 2023), Ferrymuir, Enderby, Porterstown Expansion, Mineral Wells, Mesquite, Cedar Hills, Wichita Falls,
Kilmannock Phase 1, Middleton and Big Rock. The Company is expecting to build out the portfolio of prioritised assets³ at a competitive
weighted average cost of £617k/MW and £510k/MWh.
As a leading global player in the energy storage market, the Manager prioritises fire and general safety measures. During the period, the
Manager performed site security upgrades across four sites within its GB and all the Irish operational assets.
### Energisation and commissioning timelines
Given the macro environment and future capital expenditure projections, the Manager has made a decision to optimise asset build
out based on targeted energisation date and capacity. The Investment Manager strategically decided to prioritise the following assets:
Stony, Ferrymuir, and Enderby in GB; Big Rock in California; Porterstown II expansion; and Dogfish in Texas (a total of 521.8 MW).
In the near term, the Investment Manager will prioritise larger assets over the 9.95 MW sites in the Perfect Power portfolio. The
Investment Manager is exploring opportunities to increase the capacity of the Perfect Power portfolio, similar to the expansion projects
announced for the Company’s Irish assets.
The Manager has worked to mitigate construction delays across the portfolio stemming from supply chain issues and grid operator
bottlenecks, however, some of the construction portfolio is facing delayed energisation. As of the date of publication, the energisation
process for Stony is due to commence on 31 July 2023 and Ferrymuir is now expected to be online in September-end 2023. Enderby
will follow in June 2024 and Kilmannock in December-end 2025 due to delayed grid connections. Middleton remains to be on track
for energisation in December-end 2026.
Key sensitivities
The NAV sensitivities shown in the table cover the critical macroeconomic factors and valuation assumptions that affect the NAV of the
portfolio. The value of the portfolio broadly rises with an increase in inflation, lowering of discount rate, weakening of the pound and a
decrease in EPC pricing secured for assets yet to be built out.

# Message from Alex O’ Cinneide

## Dr Alex O’Cinneide

CEO of Gore Street Capital, the Investment Manager

I’m delighted to report that the Company has continued to deliver for shareholders through a focus on building a robust and diversified portfolio during a historic year for the energy market.

As the Company continued to pursue its strategy of delivering a well-diversified market leading stream of income, built on the lowest cost per MW/h installed and leading optimisation of revenue opportunities, market developments around the world demonstrated why our mandate to seek out investments across different geographies is the correct approach.

The passing of the game-changing Inflation Reduction Act – the most ambitious and important piece of climate legislation the world has ever seen – validates the Company’s acquisitions in the US over the reporting period. The under-construction projects will benefit from investment tax credits (ITCs) covering at least 30% of capital expenditure under the policy package targeting $369bn towards energy security and climate change initiatives.

The positivity around this legislation was offset by the outbreak of war, with Russia’s invasion of Ukraine upending the European market as gas prices increased. As countries previously reliant on Russian gas race to lower their exposure to fossil fuels, the need for energy storage will continue to grow as higher levels of renewable generation are brought onto European grid systems.

We’ve already seen this reflected in a series of policy recommendations made by the European Commission in March 2023, which all centred on deploying energy storage to support the wider adoption of renewables.

This recognition of energy storage as the crucial technology to underpin decarbonised and secure energy systems worldwide shows that policymakers have caught up to what we’ve seen in the technology all along. Our internationally diverse portfolio is already well positioned to act on the increased opportunities we expect to emerge while protecting the Company from seasonal variations in revenue experienced in individual markets.

The Company’s GB portfolio, for example, performed well in the first half of the reporting period thanks to our success across ancillary services, which continued to play a dominant role in the revenues available to energy storage systems. Strong revenues from DS3 services in Ireland, meanwhile – mainly driven by increased generation from renewables in winter months – meant the Company’s Irish assets produced the highest revenue over the year across the portfolio, mitigating a sharp decline in revenue seen in GB in 2023 and insulating the Company on a portfolio level.

This meant falling GB revenue, broadly in line with forecasts, had a less severe impact on our portfolio due to the effectiveness of our diversification strategy. I am pleased to report the Company once again produced industry-leading returns, generating an average of £157,000/MW/yr during the 2022 calendar year.

We are, therefore, confident that our growing international presence will continue to deliver strong returns for our investors. We have made significant progress in expanding our portfolio, with 514.8 MW of construction and pre-construction phase assets acquired during the period, bringing the total pre-operational capacity to 881.6 MW. The Company has reached a

turning point at which the 25% operational capacity is expected to become 70% by the end of 2024, with assets scheduled to come online across the GB, ERCOT and CAISO grids.

The expanding portfolio further maximises our exposure to a range of revenue streams, allowing us to explore debt options across the portfolio, both in USD and GBP, including portfolio- and asset-level debt. Project-level debt for the Big Rock project is particularly interesting, given its unique revenue profile. Assets in California’s CAISO market can generate up to 40% of revenue from the Resource Adequacy mechanism, which delivers long-term, inflation-linked revenues lasting up to 20 years.

Following a period of acquisitions, we are now focused on building out the Company’s construction portfolio. As previously announced in February, the Company is well-funded for this, utilising a combination of cash on balance sheet and the judicious use of debt in line with the Company’s gearing policy. Overall our balance sheet is best in class with very strong ratios across the board.

Capital discipline remains a top priority, with capital expenditure representing the most significant expense for renewable energy solutions like energy storage. Due to the Company’s construction portfolio size, we have strategically adjusted construction schedules to capitalise on the expected decrease in capital expenditure costs for the Company’s construction assets in Texas and Kilmarnock in Ireland. This was an economic decision and aims to impact returns positively.

The Company’s ongoing expansion will continue to be supported by the technical excellence cultivated within the Investment Manager, as ensuring our systems under management are available as much as possible will continue to be a key decider of success. We are proud of our record over FY 2022/23 maintaining fleet availability above 95%, including the operational assets acquired in new grids, further demonstrating our ability to operate assets successfully across multiple jurisdictions.

We continue to invest in our in-house resources at the Investment Manager, which now has dedicated construction, asset management, and commercialisation teams, as well as providing the Company Secretary function, ESG, legal and finance expertise. Internalising these functions has resulted in higher efficiency and optimal delivery against our mandate and will continue to support the Company during this next phase of growth.

The Company’s NAV continues to show strong and incremental growth, increasing from 109.1p/share (31 March 2022) to 115.6p/share (31 March 2023), reflecting a 12.3% NAV Total Return for the reporting period. The valuation approach has delivered a true picture to our shareholders of the portfolio’s worth whilst minimising the large volatility experienced by peers and maintaining the management fee at the correct level. In line with the Company’s progressive dividend target, declared dividends for the period amount to 7.5p. With 75% of the portfolio under construction, we remain positive about delivering long-term value to shareholders as further operational capacity is brought online.

Strategic Report

## Delivery against strategy

The reported period marked a milestone year for the Company. Following a significantly oversubscribed fundraise, the Investment Manager completed four new international projects totalling 544.7 MW, bringing the total portfolio capacity to over 1.17 GW – cementing the Company as a globally diversified energy storage player. The Company has delivered against its growth and diversification strategy with entry into two new grids in the US—ERCOT (Texas) and CAISO (California)—resulting in a portfolio spanning five grids.

This US expansion began with its 69.7 MW acquisition in ERCOT—a portfolio of three 9.95 MW operational sites and four 9.95 MW construction sites followed by the acquisition of the Dogfish (75.0 MW) project, also in Texas, in January 2023. The scale of the Company's US pre-construction portfolio warrants lower expected construction capital expenditure on a per MW basis due to the economies of scale that can be achieved. ERCOT is a high-growth market that remains an area of interest for the Company.

In the GB market, the Company completed the 200.0 MW Middleton acquisition, representing one of the largest standalone storage acquisitions of its kind. The scale of this GB acquisition further established the Company's commitment to invest in proven markets where its existing operational portfolio has demonstrated success. It is also reflective of the type of asset that our portfolio is geared to, relevant to the energy system. Its size will help the Company achieve best-in class cost, while being connected to the transmission network will allow it to avail of cost savings and new revenue streams. We shall make a decision over the next 12 months on what duration this asset should be depending on factors such as capex and revenue streams. To date our minimising of capex and duration in the GB market has been proved correct again and again.

The final acquisition completed during the reported period was the landmark 200.0 MW / 400.0 MWh acquisition of Big Rock in CAISO – the Company's first acquisition in this market, furthering the geographical diversification of the portfolio. CAISO is an attractive market featuring contracted revenues through Resource Adequacy and merchant revenue opportunities through trading and ancillary services. The project is on track to meet its target energisation of December-end 2024.

Alongside the portfolio growth, the Manager has maintained a focus on allocating capital for the buildout of the construction and pre-construction portfolio. The successful commissioning of Porterstown (30.0 MW/30.0 MWh) in January 2023 added the Republic of Ireland to its EBITDA-generating jurisdiction. The asset will benefit from contracted income for the first six years of its operations under the DS3 Capped programme, further diversifying the Company's revenue stack and risk profile.

The Company has made further progress on the construction of its near-term 186.8 MW GB portfolio, including the Stony (79.9 MW/79.9 MWh), Ferrymuir (49.9 MW/49.9 MWh) and Enderby (57.0 MW/57.0 MWh) projects.

The Company secured lucrative Capacity Market contracts for its GB and Irish assets in the February 2023 auction. In addition to the one-year T-4 contracts secured for £63/kW for five of its operational GB assets, the Company also secured a 15-year T-4 contract for the Middleton asset and now has 15-year contracts for the entire GB construction portfolio. The two 50.0 MW assets in NI secured contracts from 2022 until 2027, and Porterstown in ROI secured a CM contract for 2026-2027.

## Outlook

Over the next twelve months, we are focused on our portfolio along the following areas:

1) bringing projects to operation at the lowest cost per MW/MWh fully installed.
2) generating the highest revenue per MW/MWh in each of the markets in which we are competing in.
3) utilising our economics of scale to materially increase EBITDA margin.
4) creating increased capacity in our existing projects over the original project size.

The Investment Manager's focus has therefore transitioned primarily to building out the Company's 881.6 MW of construction assets located across four grids and optimising the capital structure of the Company. With 521.8 MW scheduled to be commissioned by the end of 2024, the Company seeks to optimise cash generation and, in turn, dividend cover.

The Manager is assessing project finance and Company leverage structures to fund the buildout of the construction portfolio. Lenders have become more comfortable with the prospect of merchant revenues in the energy storage market after observing a solid track record of operational and revenue performance and an accelerated growth rate of key industry players. Debt will enable more flexibility in capital deployment and improved returns for shareholders. As of the date of publication, the Company has increased its existing facility with Santander from £15m to £50m. The Investment Manager is also actively engaging other project-level debt providers to optimise the capital structure of suitable assets.

The conviction on the long-term success of energy storage continues to be based on the fundamental market drivers of climate action and energy security, supported by policies and legislation of several governments around the world. The Manager will continue engaging with grid operators to explore and capitalise on new revenue opportunities, such as National Grid ESO's "black-start" and ERCOT's "ECRS" programmes in GB and Texas, respectively. As discussions regarding the future of the revenue stack remain ongoing, the Manager will continue to assess the target duration of construction assets in the procurement process. It is confident in its ability to retrofit the three GB assets targeting energisation during the next 12 months with additional duration should capex prices and revenue opportunities align to create an advantageous environment to do so. The large portfolio of construction assets to be brought online in the near future will bolster the industry-leading revenue generation already achieved by the existing international fleet. The increased operational capacity and resulting cash generation will support the progressive dividend target and contribute to the Company's continued profitability and support growth in Net Asset Value.

The reporting period has showcased the portfolio's value and ability to deliver consistently across multiple uncorrelated energy systems. The forthcoming increase in operational capacity will add to this established success and, combined with the appropriate valuation applied to the Company's revenue forecasts, create significant value. These factors enable the Company to allocate capital efficiently to meet the target IRR outlined within its mandate while justifying appropriate asset valuations.

The creation of this shareholder value allows the Company to continue to deliver energy storage as the critical asset class needed to integrate renewable generation contribute towards global decarbonisation and, ultimately, drive forward the fight against climate change.

have acted in good faith in the way that would be most likely to promote the success of the Company for the benefit of its members as
a whole, while also considering the broad range of stakeholders who interact with and are impacted by its business, especially with
regard to principal decisions.
In doing the above, the Directors have taken into account the following:
(a) the likely consequences of any decision in the long-term;
(b) the need to foster the Company’s business relationships with suppliers, customers and others;
(c) the impact of the Company’s operations on the community and the environment;
(d) the desirability of the Company maintaining a reputation for high standards of business conduct; and
(e) the need to act fairly as between members of the Company.
KEY STAKEHOLDERS
Stakeholder Why they are important and how the Company engages with them
Shareholders Shareholders own the Company and the Board is focused on delivering shareholder returns in line
with the investment policy. Shareholders and prospective investors are also key to implementing
the Company’s strategy. Engagement activities include obtaining shareholder and prospective
investor buy-in for delivery of strategic objectives.
The Company will continue to engage with shareholders in future either directly or via the
Company’s brokers and Manager.
The Manager (Investment Manager and The Investment Manager is responsible for the development and implementation of the
Commercial Manager) investment strategy, including the acquisition, origination, and execution of projects. The
Commercial Manager is responsible for management of the assets. Together they work to help the
Company meet the expectations of its investors and the targets in the Investment and Dividend
Policies.
The Board and the Manager maintain an ongoing open dialogue on key issues facing the
Company. This open dialogue takes the form of regular and ad hoc board meetings and more
informal contact, as appropriate.
Service providers and The Company engages service providers who provide management, administration and other
contractors services. The intention is to maintain long-term and high-quality business partnerships to ensure
stability while the Company pursues its growth strategy.
The Company and its investments are reliant on the Manager selecting reputable suppliers and
experienced O&M service providers. The failure of any of the Group’s suppliers (including EPC
contractors and O&M service providers) may result in closure, seizure, enforced dismantling or
other legal action in respect of the Group’s projects.

Subcontractors and The Company’s service providers and contractors are dependent on other service providers and
the project supply chain suppliers. The Company is mindful that its subcontractors and project supply chain can affect
theCompany.
The Company selects contractors adhering to the highest standards in their respective fields and
requests reporting on the application of those standards on a regular basis.
Regulators, governments and grid operators The Company is subject to regulations in each of the geographies it operates in. The Board
regularly considers how it meets regulatory and statutory obligations and follows voluntary and
best practice guidance, including how any governance decisions it makes impact its stakeholders
both in the short and long term. The Manager engages with regulators and grid operators on the
Company’s behalf.
Local communities and The Board recognises the importance of the communities in which the Company operates. As the
the environment Company develops assets closer to communities, it will ensure that its environmental and social
footprint takes account of the local communities and is sympathetic to the locality, taking account
of local views which will be obtained via the planning process.

### Risk Management and Internal Control
The Board is responsible for the Company’s system of risk management and internal control and for reviewing its effectiveness. The
Board has adopted a detailed matrix of principal risks affecting the Company’s business as an investment trust and has established
associated policies and processes designed to manage and, where possible, mitigate those risks, which are monitored by the audit
committee on an ongoing basis. This system assists the Board in determining the nature and extent of the risks it is willing to take in
achieving the Company’s strategic objectives. Both the principal risks and the monitoring system are also subject to robust review at
least annually. The last review took place in July 2023.
Although the Board believes that it has a robust framework of internal controls in place this can provide only reasonable, and not
absolute, assurance against material financial misstatement or loss and is designed to manage, not eliminate, risk.
Actions taken by the Board and, where appropriate, its committees, to manage and mitigate the Company’s principal risks and
uncertainties are set out in the table below.
*The “Change” column on the right highlights at a glance the Board’s assessment of any increases or decreases in risk during the year
after mitigation and management. The arrows show the risks as increased or decreased.
EMERGING RISKS AND UNCERTAINTIES
During the year, the Board also discussed and monitored risks that could potentially impact the Company’s ability to meet its strategic
objectives. These were political risk, and climate change risk. Political risk includes regulatory and legal changes impacting strategy,
and potential changes to national and cross-border energy policy. Climate change risk was reviewed during the year and following
its assessment, the audit and risk committee recommended and the Board agreed that climate change risk should be included in the
principal risks.
The Board has determined they are not currently sufficiently material for the Company to be categorised as independent principal
risks. The Board receives updates from the Manager, Company Secretary and other service providers on other potential risks that
could affect the Company. The Board also considered the uncertainties caused by the conflict in Ukraine, the threat of a global
recession and increasing energy prices although they are not factors which explicitly impacted the Company’s performance.

RISK ASSESSMENT AND INTERNAL CONTROLS REVIEW BY THE BOARD
Risk assessment includes consideration of the scope and quality of the systems of internal control operating within key service
providers, and ensures regular communication of the results of monitoring by such providers to the audit and risk committee, including
the incidence of significant control failings or weaknesses that have been identified at any time and the extent to which they have
resulted in unforeseen outcomes or contingencies that may have a material impact on the Company’s performance or condition.
No significant control failings or weaknesses were identified from the audit and risk committee’s ongoing risk assessment which has
been in place throughout the financial year and up to the date of this report. The Board is satisfied that it has undertaken a detailed
review of the risks facing the Company.
A full analysis of the financial risks facing the Company is set out in note 18 to the Financial Statements on pages 82 to 84.

of 7%, provided that the closing NAV per share exceeds the high water mark NAV at the date the last performance fee was paid. The performance fee is capped at 50% of the annual management fee.

The AIFM Agreement can be terminated by either party on 12 months' notice by either party, as well as in certain other circumstances such as breaches or insolvency.

During the year, and with effect from 16 December 2022 the termination provisions in the AIFM Agreement were varied such that in the specific event of a takeover offer for the Company becoming wholly unconditional the AIFM Agreement will terminate automatically with no requirement for notice to be served and the Investment Manager will be entitled to a performance fee equal to 20 per cent. of the amount (if any) by which the offer price multiplied by the number of ordinary shares in issue exceeds the prescribed benchmark for payment of a performance fee, such fee to be capped at 3.49% of NAV in the financial year to 31 March 2023 and 3.99% of NAV thereafter (the 'Exit Performance Fee') plus a fee equal to 1 per cent. of Adjusted NAV; or where no Exit Performance Fee is payable, the Investment Manager will instead be entitled to a fee equal to 2 per cent. of Adjusted NAV (the 'Minimum Takeover Fee'). If the aggregate amount of any Exit Performance Fee payable plus 1 per cent. of Adjusted NAV is less than the Minimum Takeover Fee, then the Investment Manager shall instead receive the Minimum Takeover Fee.

The management engagement committee reviewed the performance of the Investment Manager during the year under review and agreed that the Investment Manager continues to have the appropriate depth and quality of resource to deliver superior returns over the longer term. The Board received, and approved, the recommendation that Investment Manager's appointment under the terms of the AIFM agreement is in the best interests of shareholders as a whole.

For details of the fees paid to the Investment Manager, please refer to note 6 on page 75.

## THE COMMERCIAL MANAGER

Gore Street Operational Management Limited (the Commercial Manager) has been appointed to provide various commercial services to the Company, including asset management and construction oversight, as well as administrative, accounting and company secretarial support.

## THE DEPOSITARY

Indos Financial Limited is the Depositary to the Company. It is authorised and regulated by the Financial Conduct Authority. As Depositary it is responsible for oversight of the Company and Investment Manager, cash-flow monitoring, and record keeping and verification of assets.

## THE ADMINISTRATOR

Apex Group Fiduciary Services (UK) Limited (previously Sanne Group Fiduciary Services (UK) Limited) ('Apex') is Administrator to the Company.

During the year ended 31 March 2023, as Administrator, Apex on behalf of the Directors, was responsible for the maintenance of accounting records, preparation of the annual financial statements, cash management services comprising processing and making payments for the Company and the calculation, in conjunction with the Investment Manager, of the Net Asset Value of the Company.

## Corporate Governance Code disclosures

The Board has considered the Principles and Provisions of the AIC Code of Corporate Governance (AIC Code). The AIC Code addresses the Principles and Provisions set out in the UK Corporate Governance Code (the UK Code), as well as setting out additional Provisions on issues that are of specific relevance to the Company. The Board considers that reporting against the Principles and Provisions of the AIC Code, which has been endorsed by the Financial Reporting Council provides more relevant information to shareholders.

The Company has complied with the Principles and Provisions of the AIC Code. The AIC Code is available on the AIC website (www.theaic.co.uk). It includes an explanation of how the AIC Code adapts the Principles and Provisions set out in the UK Code to make them relevant for investment companies.

The Financial Conduct Authority requires all UK listed companies to disclose how they have complied with the provisions of the UK Code. This statement, together with the Statement of Directors' Responsibilities, viability statement and going concern statement set out on pages 59 and 46 respectively, indicates how the Company has complied with the principles of good governance of the AIC Code and its requirements on internal control. The Strategic Report and Directors' Report provide further details on the Company's internal controls (including risk management), governance and diversity policy.

The Board confirms that the Company has complied with the AIC Code during the year under review.

## Revenue and Dividends

The financial statements of the Company for the period appear from page 66. Total Comprehensive income for the year 31 March 2023 was £63,412,295 (31 March 2022 £42,527,570). The Directors have approved a fourth interim dividend of 1.5 pence per share be paid, bringing the total dividend in respect of the period ended 31 March 2023 to 7.5 pence per share (7 pence per share 31 March 2022), in line with the Dividend Policy.

## Dividend Policy

Subject to market conditions and performance, financial position, and financial outlook, it is the Directors' intention to pay an attractive level of dividend income to shareholders on a quarterly basis.

The Company will target dividends in respect of the Ordinary Shares in each financial year based on a 7 per cent. yield on the average Net Asset Value per Ordinary Share during that financial year, subject to a minimum target of 7 pence per Ordinary Share in each financial year. The annual target dividend will increase by 0.5 pence increments per Ordinary Share based on a certain progression of the average Net Asset Value per Ordinary Share in any financial year above 100 pence (subject to rounding).

Dividends are paid quarterly, and the Company will target a dividend of 2.0 pence per Ordinary Share for the first three interim dividends in each financial year and the amount of the final dividend will depend on the overall annual dividend target for that financial year. Investors should note that the payment of dividends is at the discretion of the Board and the Directors may resolve to pay dividends otherwise than in accordance with the targets noted above in order to reflect the Company's expected returns and future plans for the growth of the Company.

Shareholders are invited to approve the dividend policy at each AGM.

## SUCCESSION

The committee agreed that the succession policy remained appropriate.

Noting that the four Directors appointed at IPO would need to retire on the same date, the committee agreed that it would be appropriate for one of those Directors to step down from the Board earlier than a full nine-year term, and that one Director may stay on the Board for up to ten years, so as to stagger retirement dates and avoid disruption.

The committee also agreed that the Company should aim to appoint another Director in 2024/25, and every two or three years thereafter.

## REMUNERATION

The committee reviewed Directors' fees, using external benchmarking, and recommended an increase in Directors' fees, as detailed in the remuneration report.

# Directors' remuneration report

## Introduction

The following remuneration policy is currently in force and is subject to a binding vote every three years. The next vote will take place in 2025 and the current policy provisions will apply until that date. An ordinary resolution to approve the Directors' remuneration policy will be put to shareholders at the forthcoming AGM (no changes are proposed). The below Directors' annual report on remuneration is subject to an annual advisory vote. An ordinary resolution to approve this report will be put to shareholders at the forthcoming AGM.

At the AGM held on 20 September 2022, 99.86% of the votes cast (including votes cast at the Chairman's discretion) in respect of approval of the remuneration policy were in favour, while 0.14% were against and 255,185 votes were withheld.

At the AGM held on 20 September 2022, 97.97% of the votes cast (including votes cast at the Chairman's discretion) in respect of approval of the report on remuneration for the year ended 31 March 2022 were in favour, while 2.03% were against and 255,185 votes were withheld.

## Directors' remuneration policy

The Company's policy is to determine the level of Directors' fees with due regard to the experience of the Board as a whole, the time commitment required, and to be fair and comparable to non-executive Directors of similar companies. The Company may also periodically choose to benchmark Directors' fees

with an independent review to ensure they remain fair and reasonable.

Directors' fees will be adjusted from time to time and will be subject to shareholder approval in the subsequent AGM. The Directors may elect to apply the cash amount equal to their annual fee to subscribe for, or to purchase, Ordinary Shares. The Directors are entitled only to their annual fee and their reasonable expenses. No element of the Directors' remuneration is performance related, nor does any Director have any entitlement to pensions, share options or any long-term incentive plans from the Company.

The Directors hold their office in accordance with the Articles of Association and their appointment letters. No Director has a service contract with the Company, nor are any such contracts proposed. The Directors' appointments can be terminated in accordance with the Articles of Association and without compensation. Under the Company's Articles of Association, all Directors are entitled to remuneration determined from time to time by the Board and approved by shareholders.

## Application of the Directors' remuneration policy

The Board did not seek the views of shareholders in setting this remuneration policy. Any comments on the policy received from shareholders would be considered on a case-by-case basis.

As the Company does not have any employees, no employee pay and employment conditions were taken into account when setting this remuneration policy and no employees were consulted in its construction. The Directors did not receive any shareholder feedback on the policy.

Directors' fees are reviewed annually and take into account research from third parties on the fee levels of Directors of peer group companies, as well as industry norms and factors affecting the time commitment expected of the Directors. New Directors are subject to the provisions set out in this remuneration policy.

## Directors' annual report on remuneration

This report explains how the Directors' remuneration policy was implemented during the year ended 31 March 2023.

Directors' remuneration was last reviewed by the remuneration and nomination committee and the Board in April 2023. The members of the committee at the time that remuneration levels were considered were all the Directors, except Lisa Scenna, who joined the Board on 1 May 2023. Although no external advice was sought in considering the levels of Directors' fees, information on fees paid to Directors of peer group companies provided by the Secretary and Corporate Broker was taken into consideration, as was independent third-party research.

Following this review, the committee recommended, and the Board agreed, that Directors' fees should be increased by £2,000, with effect from 1 April 2023, to align with the new financial year. As a result, all non-executive Directors will be paid £47,000 per annum. The Chair receives an additional £30,000 and the audit chair an additional £10,000. Fees were last increased with effect from 1 July 2022.

### 62 Gore Street Energy Storage Fund plc
Independent Auditor's Report

|  Risk | Our response to the risk | Key observations communicated to the Audit Committee  |
| --- | --- | --- |
|  **Inaccurate valuation of investments** *Refer to the Audit Committee Report (page 53); Accounting policies (page 72); and notes 12 and 17 of the Financial Statements on pages 78 (for note 12) and 81 (for note 17).* The valuation of the investment portfolio as at 31 March 2023 was £434.76 million (2022: £180.76) consisting of the Company's investments in battery storage assets through its wholly owned subsidiary, GSES1 Limited and its subsidiaries. The Company meets the definition of an 'investment entity' in accordance with IFRS 10, thus it values its investment in its subsidiary at fair value through profit or loss. The accurate valuation of investments is fundamental to the Company's financial performance. The return generated by the investment portfolio is a key driver of the Company's returns. Due to the nature of the investment portfolio, being unlisted investments with no directly comparable listed investments, the underlying assumptions that drive the value of the asset are subjective. As a result, the valuation of the portfolio is susceptible to misstatement. The investment valuation approach requires sufficient rigour to eliminate the susceptibility of the investment valuations to bias. The valuation principles used are based on International Valuation Standards Council ('IVSC') valuation guidelines, using a discounted cash flow ('DCF') methodology. | We performed the following procedures: Gained an understanding of the Investment Manager and Directors' processes and controls surrounding investment valuations, by performing a walkthrough to evaluate the design and implementation of controls. Obtained and reviewed the valuation models of each asset held via the Company's investment in GSES1 Limited and its subsidiaries to validate that the valuation methodology adopted is consistent with the requirements of IFRS and IVSC guidelines. Corroborated key revenue streams and other valuation model inputs to supporting contracts and external pricing forecasts, as applicable. Held discussions with the Investment Manager to understand the key drivers to the cash flow projections included in the valuation models and assessed their appropriateness based on the nature of the asset and our understanding of the relevant markets. For a selected sample of investments, engaged EY valuation specialists to assist in challenging the appropriateness of the discount rate used and to assess the impact of macro-economic and industry related factors used in calculating the net present value of the future cash flows. For the remainder of the investments, we ensured that consistent valuation methodology was applied and challenged the key estimates used in determining the fair value of the investments. Performed back testing by comparing prior year revenue and expense projections to current year actuals, to assess reasonableness of projections. Checked the clerical accuracy of the valuation models. | Our audit procedures did not identify any material misstatements regarding the risk of incorrect valuation of investments.  |

There have been no changes to the areas of audit focus raised in the above risk table from the prior year.

## Our application of materiality

We apply the concept of materiality in planning and performing the audit, in evaluating the effect of identified misstatements on the audit and in forming our audit opinion.

## Materiality

*The magnitude of an omission or misstatement that, individually or in the aggregate, could reasonably be expected to influence the economic decisions of the users of the financial statements. Materiality provides a basis for determining the nature and extent of our audit procedures.*

We determined materiality for the Company to be £5.56 million (2022: £3.60 million), which is 1% (2022: 1%) of net assets. We believe that net assets are the most important financial metric on which shareholders would judge the performance of the Company.

## Performance materiality

*The application of materiality at the individual account or balance level. It is set at an amount to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected misstatements exceeds materiality.*

On the basis of our risk assessments, together with our assessment of the Company's overall control environment, our judgement was that performance materiality was 75% (2022: 75%) of our planning materiality, namely £4.17m (2022: £2.70m). We have set performance materiality at this percentage due to our past experience of the audit that indicates a lower risk of misstatements, both corrected and uncorrected.

## Reporting threshold

*An amount below which identified misstatements are considered as being clearly trivial.*

We agreed with the Audit Committee that we would report to them all uncorrected audit differences in excess of £0.28m (2021: £0.18m), which is set at 5% of planning materiality, as well as differences below that threshold that, in our view, warranted reporting on qualitative grounds.

We evaluate any uncorrected misstatements against both the quantitative measures of materiality discussed above and in light of other relevant qualitative considerations in forming our opinion.

# Notes to the Financial Statements

For the Year Ended 31 March 2023

## 1. General information

Gore Street Energy Storage Fund plc (the “Company”), a public limited company limited by shares was incorporated and registered in England and Wales on 19 January 2018 with registered number 11160422. The registered office of the Company is 16-17 Little Portland Street, First Floor, London, W1W 8BP.

Its share capital is denominated in Pound Sterling (GBP) and currently consists of Ordinary Shares. The Company’s principal activity is to invest in a diversified portfolio of utility scale energy storage projects currently located in the UK, the Republic of Ireland, North America and Germany.

## 2. Basis of preparation

### STATEMENT OF COMPLIANCE

The annual financial statements have been prepared in accordance with UK adopted international accounting standards. The Company has also adopted the Statement of Recommended Practice issued by the Association of Investment Companies which provides guidance on the presentation of supplementary information.

The financial statements have been prepared on a historical cost basis except for financial assets and liabilities at fair value through the profit or loss.

The Company is an investment entity in accordance with IFRS 10 which holds all its subsidiaries at fair value and therefore prepares separate accounts only.

### FUNCTIONAL AND PRESENTATION CURRENCY

The currency of the primary economic environment in which the Company operates (the functional currency) is Pound Sterling (“GBP or £”) which is also the presentation currency.

### GOING CONCERN

In assessing the going concern basis of accounting the Directors have had regard to the guidance issued by the Financial Reporting Council. After making enquiries and bearing in mind the nature of the Company’s business and assets, the Directors consider the Company to have adequate resources to continue in operational existence over the period to 30 September 2024, being at least 12 months from the date of approval of the financial statements. As such, they have adopted the going concern basis in preparing the annual report and financial statements.

The going-concern analysis takes into account expected increases to Investment Adviser’s fee in line with the Company’s NAV and expected increases in operating costs, as well as continued discretionary dividend payments to shareholders at the annual target rate of 7% of NAV, subject to a minimum target of 7 pence per Ordinary Share in each financial year. Consideration has been given to the current macro-economic environment and volatility in the markets. Based on the analysis performed, the Company will continue to be operational and will have excess cash after payment of its liabilities for at least the next 12 months to 30 September 2024.

As at 31 March 2023, the Company had net current assets of £121.5 million and had cash balances of £123.7 million (excluding cash balances within investee companies), which are sufficient to meet current obligations as they fall due. The major cash outflows of the Company are the payment of dividends, costs relating to the acquisition of new assets and further investments in existing portfolio Companies, all of which, are discretionary. The Company is a guarantor to GSES1 Limited’s revolving credit facility with Santander. Subsequent to year end this facility was upsized from £15m to £50m, with an extended term of four years to 2027. The Company had no outstanding debt as at 31 March 2023.

Shareholders will have the opportunity to vote on an ordinary resolution on the continuation of the Company at the AGM of the Company to be held in 2023. The Directors have considered this when evaluating the going concern assessment for the Company and have no reason to believe that such resolution will not be passed by shareholders.

The Directors acknowledge their responsibilities in relation to the financial statements for the year ended 31 March 2023 and have prepared the financial statement on a going concern basis. The Company expects to meet its obligations as and when they fall due for at least the next twelve months to 30 September 2024.

The Board has considered the impact of climate change on the investments included in Company’s financial statements and has assessed that it does not materially impact the estimates and assumptions used in determining the fair value of the investments.

Annual Report for year ended 31 March 2023 71
Financial Statements
### 2. Basis of preparation (continued)
OPERATING SEGMENTS
Under IFRS 8, particular classes of entities are required to disclose information about any of their individual operating segments.
Having considered that the Company’s entire portfolio is held through the Company’s direct subsidiary, GSES 1 Limited, the Directors
are of the opinion that there is only one segment and therefore no operating segment information is given.
### 3. Significant accounting judgements, estimates and assumptions
The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the
application of accounting policies and the reported amount of assets, liabilities, income and expenses. Estimates and underlying
assumptions are reviewed on an ongoing basis. Revisions to the accounting estimates are recognised in the period in which the
estimates are revised and in any future periods affected.
During the period the Directors considered the following significant judgements, estimates and assumptions:
ASSESSMENT AS AN INVESTMENT ENTITY
Entities that meet the definition of an investment entity within IFRS 10 are required to measure their subsidiaries at fair value through
profit or loss rather than consolidate them unless they provided investment-related services to the Company. As such, the Directors
are required to make a judgement as to whether the Company continues to meet the definition of an investment entity.
To determine this, the Company is required to satisfy the following three criteria:
a) the Company obtains funds from one or more investors for the purpose of providing those investors with investment management services;
b) the Company commits to its investors that its business purpose is to invest funds solely for returns from capital appreciation,
investment income, or both; and
c) the Company measures and evaluates the performance of substantially all of its investments on a fair value basis.
The Company meets the criteria as follows:
• the stated strategy of the Company is to deliver stable returns to shareholders through a mix of energy storage investments;
• the Company provides investment management services and has several investors who pool their funds to gain access to
infrastructure related investment opportunities that they might not have had access to individually; and
• the Company has elected to measure and evaluate the performance of all of its investments on a fair value basis. The fair value
method is used to represent the Company’s performance in its communication to the market, including investor presentations.
In addition, the Company reports fair value information internally to Directors, who use fair value as the primary measurement
attribute to evaluate performance.
Having assessed the criteria above and in their judgement, the Directors are of the opinion that the Company has all the typical
characteristics of an investment entity and continues to meet the definition in the standard. This conclusion will be reassessed on an
annual basis.
VALUATION OF INVESTMENTS
Significant estimates in the Company’s financial statements include the amounts recorded for the fair value of the investments. By
their nature, these estimates and assumptions are subject to measurement uncertainty and the effect on the Company’s financial
statements of changes in estimates in future periods could be significant. These estimates are discussed in more detail in note 17.
### 4. New and revised standards and interpretations
NEW AND REVISED STANDARDS AND INTERPRETATIONS
The accounting policies used in the preparation of the financial statements have been consistently applied during the year ended
31March 2023.
In February 2021, the International Accounting Standards Board issued further amendments to IAS8: Accounting Policies, Changes
in Accounting Estimates and Errors. Those amendments clarify the distinction between changes in accounting estimates, changes
in accounting policies and correction of errors. They further clarify how entities use measurement techniques and inputs to develop
accounting estimates. These amendments are effective for periods beginning on or after 1 January 2023 and having reviewed the
amendments, the Board is of the opinion that these amendments will not have a material impact on the Company’s financial statements.
### 72 Gore Street Energy Storage Fund plc
Financial Statements

## 4. New and revised standards and interpretations (continued)

In May 2021, the IASB issued amendments to IAS 12: Income Taxes regarding deferred tax relating to Assets and Liabilities arising from a Single Transaction. The amendments introduce an exception to the 'initial recognition exemption' for an entity, whereby deferred tax previously did not need to be recognised when, in a transaction that is not a business combination, an entity purchased an asset that would not be deductible for tax purposes (even though there is a difference between the asset's carrying amount and its tax base). These amendments are effective for periods beginning on or after 1 January 2023 and having reviewed the amendments, the Board is of the opinion that these amendments will not have a material impact on the Company's financial statements.

There have been no new standards, amendments to current standards, or new interpretations which the Directors feel have a material impact on these financial statements.

### NEW AND REVISED IFRS IN ISSUE BUT NOT YET EFFECTIVE

In January 2020, the International Accounting Standards Board issued amendments to IAS 1: Presentation of Financial Statements to clarify how an entity classifies debt and other financial liabilities as current or non-current. The amendments specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non-current at the reporting date. Instead, the amendments require a company to disclose information about these covenants in the notes to the financial statements. The amendments are effective for annual reporting periods beginning on or after 1 January 2024 and having reviewed the amendments, the Board is of the opinion that these amendments will not have a material impact on the Company's financial statements.

## 5. Summary of significant accounting policies

The principal accounting policies applied in the preparation of these financial statements are set out below:

### INVESTMENT INCOME

Interest income is recognised on an accrual basis in the Revenue account of the Statement of Comprehensive Income.

Investment income arising from the portfolio assets is recognised on an accruals basis in totality, with amounts received in cash recognised in investment income and the unrealised portion disclosed in net gain on investments at fair value through profit and loss.

### EXPENSES

Expenses are accounted for on an accrual basis and charged to the Statement of Comprehensive Income. Share issue costs are allocated to equity. Expenses are charged through the Revenue account except those which are capital in nature, these include those which are incidental to the acquisition, disposal or enhancement of an investment, which are accounted for through the Capital account.

### NET GAIN OR LOSS ON INVESTMENTS AT FAIR VALUE THROUGH PROFIT AND LOSS

Gains or losses arising from changes in the fair value of investments are recognised in the Capital account of the Statement of Comprehensive Income in the period in which they arise. The value of the investments may be increased or reduced by the assessed fair value movement.

### TAXATION

The Company is approved as an Investment Trust Company ('ITC') under sections 1158 and 1159 of the Corporation Taxes Act 2010 and Part 2 Chapter 1 Statutory Instrument 2011/29999 for accounting periods commencing on or after 25 May 2018. The approval is subject to the Company continuing to meet the eligibility conditions of the Corporations Tax Act 2010 and the Statutory Instrument 2011/29999. The Company intends to ensure that it complies with the ITC regulations on an ongoing basis and regularly monitors the conditions required to maintain ITC status.

From 1 April 2015 there is a single corporation tax rate of 19%, which is the rate applicable at year end. From 1 April 2023 the main UK corporation tax rate increased to 25%. Current Tax and movements in deferred tax asset and liability are recognised in the Statement of Comprehensive Income except to the extent that they relate to the items recognised as direct movements in equity, in which case they are similarly recognised as a direct movement in equity. Current tax is the expected tax payable on any taxable income for the period, using tax rates enacted or substantively enacted at the end of the relevant period. Any closing deferred tax balances have been calculated at 25% as this is the rate expected to apply in future periods.

Deferred taxation is recognised in respect of all timing differences that have originated but not reversed at the Statement of Financial Position date where transactions or events that result in an obligation to pay more tax or a right to pay less tax in the future have occurred. Timing differences are differences between the Company's taxable profits and its results as stated in the financial statements. Deferred taxation assets are recognised where, in the opinion of the Directors, it is more likely than not that these amounts will be realised in future periods, at the tax rate expected to be applicable at realisation.

Annual Report for year ended 31 March 2023 73
Financial Statements
### 5. Summary of significant accounting policies (continued)
INVESTMENT IN SUBSIDIARIES
Subsidiaries are entities controlled by the Company. Control exists when the Company is exposed, or has rights, to variable returns
from its involvement with the subsidiary entity and has the ability to affect those returns through its power over the subsidiary
entity. In accordance with the exception under IFRS 10 Consolidated financial statements, the Company is an investment entity and
therefore only consolidates subsidiaries if they provide investment management services and are not themselves investment entities.
Allsubsidiaries are investment entities and held at fair value in accordance with IFRS 9 and therefore not consolidated.
CASH AND CASH EQUIVALENTS
Cash and cash equivalents comprise cash at bank and call deposits held with the bank with original maturities of three months or less.
RESTRICTED CASH
Restricted cash comprises cash held as collateral for future contractual payment obligations and deferred payments payable from
indirect subsidiaries to third parties of the Company in relation to the Big Rock project. Restricted cash is recognised at fair value and
subsequently stated at amortised cost less loss allowance, which is calculated using the provision matrix of the expected credit loss
model (refer to note 13 for further information).
TRADE AND OTHER RECEIVABLES
Trade and other receivables are recognised initially at fair value and subsequently stated at amortised cost less loss allowance which is
calculated using the provision matrix of the expected credit loss model.
TRADE AND OTHER PAYABLES
Trade and other payables are recognised initially at fair value and subsequently stated at amortised cost.
DIVIDENDS
Dividends are recognised, as a reduction in equity in the financial statements. Interim equity dividends are recognised when legally
payable. Final equity dividends will be recognised when approved by the Shareholders.
EQUITY
Equity instruments issued by the Company are recorded at the amount of the proceeds received, net of directly attributable issue
costs. Costs not directly attributable to the issue are immediately expensed in the Statement of Comprehensive Income.
FINANCIAL INSTRUMENTS
In accordance with IFRS 9, the Company classifies its financial assets and financial liabilities at initial recognition into the categories of
amortised cost or fair value through profit or loss.
FINANCIAL ASSETS
The Company classifies its financial assets at amortised cost or fair value through profit or loss on the basis of both:
• the entity’s business model for managing the financial assets
• the contractual cash flow characteristics of the financial asset
Financial assets measured at amortised cost
A debt instrument is measured at amortised cost if it is held within a business model whose objective is to hold financial assets in
order to collect contractual cash flows and its contractual terms give rise on specified dates to cash flows that are solely payments
of principal and interest on the principal amount outstanding. The Company includes in this category short-term non-financing
receivables including cash and cash equivalents, restricted cash, and trade and other receivables.
Financial asset measured at fair value through profit or loss (FVPL)
A financial asset is measured at fair value through profit or loss if:
a) its contractual terms do not give rise to cash flows on specified dates that are solely payments of principal and interest (SPPI) on
the principal amount outstanding; or
b) it is not held within a business model whose objective is either to collect contractual cash flows, or to both collect contractual cash
flows and sell; or
c) it is classified as held for trading (derivative contracts in an asset position).
d) It is classified as an equity instrument.
The Company includes in this category equity instruments and loans to investments.
### 74 Gore Street Energy Storage Fund plc
Financial Statements
### 5. Summary of significant accounting policies (continued)
FINANCIAL LIABILITIES
Financial liabilities measured at fair value through profit or loss (FVPL)
A financial liability is measured at FVPL if it meets the definition of held for trading of which the Company had none.
Financial liabilities measured at amortised cost
This category includes all financial liabilities, including short-term payables.
RECOGNITION AND DERECOGNITION
Financial assets and liabilities are recognised on trade date, when the Company becomes party to the contractual provisions of the
instrument. A financial asset is derecognised where the rights to receive cash flows from the asset have expired, or the Company has
transferred its rights to receive cash flows from the asset. The Company derecognises a financial liability when the obligation under the
liability is discharged, cancelled or expired.
IMPAIRMENT OF FINANCIAL ASSETS
The Company holds trade receivables with no financing component and which have maturities of less than 12 months at amortised
cost and, as such, has chosen to apply the simplified approach for expected credit losses (ECL) under IFRS 9 to all its trade
receivables. Therefore the Company does not track changes in credit risk, but instead recognises a loss allowance based on lifetime
ECLs at each reporting date.
The Company’s approach to ECLs reflects a probability-weighted outcome, the time value of money and reasonable and supportable
information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of
future economic conditions.
The Company uses the provision matrix as a practical expedient to measuring ECLs on trade receivables, based on days past due for
groupings of receivables with similar loss patterns. Receivables are grouped based on their nature. The provision matrix based on
historical observed loss rates over the expected life of the receivables and is adjusted for forward looking estimates.
FAIR VALUE MEASUREMENT AND HIERARCHY
Fair value is the price that would be received on the sale of an asset, or paid to transfer a liability, in an orderly transaction between market
participants at the measurement date. The fair value measurement is based on the presumption that the transaction takes place either in
the principal market for the asset or liability, or in the absence of a principal market, in the most advantageous market. It is based on the
assumptions that market participants would use when pricing the asset or liability, assuming they act in their economic best interest.
The fair value hierarchy to be applied under IFRS 13 is as follows:
Level 1: Quoted (unadjusted) market prices in active markets for identical assets or liabilities.
Level 2: Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.
Level 3: Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.
For assets and liabilities that are carried at fair value, and which will be recorded in the financial information on a recurring basis, the
Company will determine whether transfers have occurred between levels in the hierarchy by reassessing categorisation at the end of
each reporting period.

There is no corporate tax charge for the year (2022:£nil). The Company may utilise available tax losses from within the UK tax group
to relieve future taxable profits in the Company and may also claim deductions on future distributions or parts thereof designated as
interest distributions. Therefore, a deferred tax asset, measured at the prospective corporate rate of 25% (2022: 25%) of £1,833,591
(2022: £786,963) has not been recognised in respect of carried forward tax losses. These carried forward tax losses include a
£7,220,992 tax deduction resulting from the dividend for the quarter ending 31 March 2023 being designated in full as an interest
distribution.
### 11. Earnings per share
Earnings per share (EPS) amounts are calculated by dividing the profit or loss for the period attributable to ordinary equity holders
of the Company by the weighted average number of Ordinary Shares in issue during the period. As there are no dilutive instruments
outstanding, basic, and diluted earnings per share are identical.

The Company meets the definition of an investment entity. Therefore, it does not consolidate its subsidiaries or equity method account
for associates but, rather, recognises them as investments at fair value through profit or loss. The Company is not contractually
obligated to provide financial support to the subsidiaries and associate, except as guarantor to the debt facility entered into by its
direct subsidiary GSES 1 Limited, and there are no restrictions in place in passing monies up the structure.
The investment in GSES1 is financed through equity and a loan facility available to GSES1. The facility may be drawn upon, to any
amount agreed by the Company as lender, and is available for a period of 20 years from 28 June 2018. The rest of the investment in
GSES1 is funded through equity. The amount drawn on the facility at 31 March 2023 was £309,182,178 (2022: £116,009,272).
The loan is interest bearing and attracts interest at 5% per annum. Investments in the indirect subsidiaries are also structured through
loan and equity investments and the ultimate investments are in energy storage facilities.
Realisation of increases in fair value in the indirect subsidiaries will be passed up the structure as repayments of loan interest and
principal. GSES1 controls GSF Albion, GSF England, GSF IRE and GSF Atlantic as listed below which in turn hold an interest in project
companies. GSF Atlantic also controls GSF Americas, which itself invests in its own project companies.

### 17. Fair Value measurement
VALUATION APPROACH AND METHODOLOGY
There are three traditional valuation approaches that are generally accepted and typically used to establish the value of a business; the
income approach, the market approach, and the net assets (or cost based) approach. Within these three approaches, several methods
are generally accepted and typically used to estimate the value of a business.
The Company has chosen to utilise the income approach, which indicates value based on the sum of the economic income that an
asset, or group of assets, is anticipated to produce in the future. Therefore, the income approach is typically applied to an asset that is
expected to generate future economic income, such as a business that is considered a going concern. Free cash flow to total invested
capital is typically the appropriate measure of economic income. The income approach is the Discounted Cash Flow (“DCF”) approach
and the method discounts free cash flows using an estimated discount rate (Weighted Average Cost of Capital (“WACC”)).
VALUATION PROCESS
In the year, the Company, via its subsidiaries, acquired eight projects totalling 144.65 MW connected to The Electric Reliability Council
of Texas, Inc. (“ERCOT”) and a 200MW project in the scope of the California Independent System Operator (“CAISO”). It also acquired
a 200MW project Middleton in England. These acquisitions bring the Company’s portfolio of lithium-ion energy storage investments to
a total capacity of 1.17GW (2022: 628.5 MW). As at 31March2023, 291.6 MW of the Company’s total portfolio was operational and
881.6 MW pre-operational (the “Investments”).
The Investments comprise thirty-six projects, based in the UK, the Republic of Ireland, mainland Europe or North America. The
Directors review and approve these valuations following appropriate challenge and examination. The current portfolio consists of
non-market traded investments and valuations are analysed using forecasted cash flows of the assets and used the discounted cash flow
approach as the primary approach for the valuation. The Company engages external, independent and qualified valuers to determine the
fair value of the Company’s investments or valuations are produced by the Investment Advisor.
As at 31 March 2023, the fair value of the portfolio of investments has been determined by the Investment Manager and reviewed by
BDO UK LLP.
The below table summarises the significant unobservable inputs to the valuation of investments.

• Valuation of financial instruments
The investments at fair value through profit or loss are Level 3 in the fair value hierarchy. No transfers between levels took place during
the year.
### 18. Financial risk management
The Company is exposed to certain risks through the ordinary course of business and the Company’s financial risk management objective
is to minimise the effect of these risks. The management of risks is performed by the Directors of the Company and the exposure to each
financial risk is considered potentially material to the Company, how it arises and the policy for managing it is summarised below:
• Capital risk management
The capital structure of the Company at year end consists of equity attributable to equity holders of the Company, comprising issued
capital, reserves and accumulated gains. The Board continues to monitor the balance of the overall capital structure so as to maintain
investor and market confidence. The Company is not subject to any external capital requirements.
• Counterparty risk
The Company is exposed to third party credit risk in several instances, including the possibility that counterparties with which the
Company and its subsidiaries, together the Group, contract with, may default or fail to perform their obligations in the manner anticipated
by the Group. Such counterparties may include (but are not limited to) manufacturers who have provided warranties in relation to the
supply of any equipment or plant, EPC contractors who have constructed the Company’s projects, who may then be engaged to operate
assets held by the Company, property owners or tenants who are leasing ground space and/or grid connection to the Company for the
location of the assets, contractual counterparties who acquire services from the Company underpinning revenue generated by each
project or the energy suppliers, or demand aggregators, insurance companies who may provide coverage against various risks applicable
to the Company’s assets (including the risk of terrorism or natural disasters affecting the assets) and other third parties who may owe
sums to the Company. In the event that such credit risk crystallises, in one or more instances, and the Company is, for example, unable
to recover sums owed to it, make claims in relation to any contractual agreements or performance of obligations (e.g. warranty claims) or
require the Company to seek alternative counterparties, this may materially adversely impact the investment returns.
### 82 Gore Street Energy Storage Fund plc
Financial Statements

## 18. Financial risk management (continued)

Further the projects in which the Company may invest will not always benefit from a turnkey contract with a single contractor and so will be reliant on the performance of several suppliers. Therefore, the key risks during battery installation in connection with such projects are the counterparty risk of the suppliers and successful project integration. The Company accounts for its exposure to counterparty risk through the fair value of its investments by using appropriate discount rates which adequately reflects its risk exposure.

The Company regularly assesses the creditworthiness of its counterparties and enters into counterparty arrangements which are financially sound and ensures, where necessary, the sourcing of alternative arrangements in the event of changes in the creditworthiness of its present counterparties.

### • Concentration risk

The Company's investment policy is limited to investment in energy storage infrastructure in the UK, Republic of Ireland, North America, Western Europe, Australia, Japan, and South Korea. The value of investments outside of the UK is not intended to exceed 60% of Gross Asset Value of the Company. Significant concentration of investments in any one sector and location may result in greater volatility in the value of the Group's investments and consequently the Net Asset Value and may materially and adversely affect the performance of the Group and returns to Shareholders. The Company currently has investments located across 5 different grids in the UK, Republic of Ireland, North America (ERCOT and CAISO), and Germany. This diversification reduces exposure to any single grid. The investment policy also limits the exposure to any single asset within the portfolio to 25% of the Gross Asset Value of the Company.

### • Credit risk

The Company regularly assesses its credit exposure and considers the creditworthiness of its customers and counterparties. Cash and bank deposits are held with Barclays plc, Santander UK plc and JPMorgan Chase and Co., all reputable financial institutions with Moody's credit ratings of Baa2, A1 and Aa2 respectively.

### • Liquidity risk

The objective of liquidity management is to ensure that all commitments which are required to be funded can be met out of readily available and secure sources of funding. The Company may, where the Board deems it appropriate, use short-term leverage to acquire assets but with the intention that such leverage be repaid with funds raised through a new issue of equity or cash flow from the Company's portfolio. Such leverage will not exceed 30 per cent. at the time of borrowing of Gross Asset Value without Shareholder approval. The Company intends to prudently introduce a conservative amount of debt throughout the portfolio. The Company's only financial liabilities as at 31 March 2023 are trade and other payables. The Company has sufficient cash reserves to cover these in the short-medium term. The Company's cash flow forecasts are monitored regularly to ensure the Company is able to meet its obligations when they fall due. The Company's investments are level 3 and thus illiquid and this is taken into assessment of liquidity analysis.

The following table reflects the maturity analysis of financial assets and liabilities.

Investments include both equity and debt instruments. As the equity instruments have no contractual maturity date, they have been
included with the >5-year category. Additionally, the debt instruments have an original maturity of 20 years.
• Market risk
Market risk is the risk that the fair value or cash flows of a financial instrument will fluctuate due to changes in market prices. Market
risk reflects currency risk, interest rate risk and other price risks. The objective is to minimise market risk through managing and
controlling these risks to acceptable parameters, while optimising returns. The Company uses financial instruments in the ordinary
course of business, and also incurs financial liabilities, in order to manage market risks.
i) Currency risk
The majority of investments, together with the majority of all transactions during the current period were denominated in Pounds
Sterling.
The Company, via GSES 1 and its direct subsidiaries, holds two investments (Kilmannock and Porterstown) in the Republic of
Ireland, an investment in Germany (Cremzow), and several investments in North America, creating an exposure to currency risk.
These investments have been translated into Pounds Sterling at year end and represent 36% (2022: 16.69%) of the Company’s fair
valued investment portfolio. The Company regularly monitors its exposure to foreign currency and executes appropriate hedging
arrangements in the form of forward contracts with reputable financial institutions to reduce this risk. These derivatives are held by the
Company’s subsidiaries.
ii) Interest rate risk
Interest rate risk arises from the possibility that changes in interest rates will affect future cash flows or the fair values of financial
instruments. The Company is exposed to interest rate risk on its cash balances held with counterparties, bank deposits, advances
to counterparties and through loans to related parties. Loans to related parties carry a fixed rate of interest for an initial period of
20years. The Company may be exposed to changes in variable market rates of interest and this could impact the discount rate
used in the investment valuations and therefore the valuation of the projects as well as the fair value of the loan receivables. Refer to
Note 17 for the sensitivity of valuations to changes in the discount rate. The Company currently has no external debt. The Company
continuously monitors its exposure to interest rate risk and where necessary will assess and execute hedging arrangements to mitigate
interest rate risk.
iii) Price risk
Price risk is the risk that the fair value or cash flows of a financial instrument will fluctuate due to changes in market prices. If the
market prices of the investments were to increase by 10%, there will be a resulting increase in net assets attributable to ordinary
shareholders for the period of £43,476,217 (2022: £18,025,549). Similarly, a decrease in the value of the investment would result in
an equal but opposite movement in the net assets attributable to ordinary shareholders. The Company relies on the market knowledge
of the experienced Investment Advisor, the valuation expertise of the third-party valuer BDO and the use of third- party market
forecast information to provide comfort with regard to fair market values of investments reflected in the financial statements.
### 19. Net asset value per share
Basic NAV per share is calculated by dividing the Company’s net assets as shown in the Statement of Financial Position that are
attributable to the ordinary equity holders of the Company by the number of Ordinary Shares outstanding at the end of the period.
Asthere are no dilutive instruments outstanding, basic, and diluted NAV per share are identical.

### SHARE ISSUES

On 14 April 2022, the Company issued 136,363,636 ordinary shares at a price of 110 pence per share, raising net proceeds from the Placing of £150,000,000.

Following the approval at the Company's AGM on the 20 September 2022, the Company made an application to the High Court, together with a lodgement of the Company's statement of capital with the Registrar of Companies, the Company was permitted to reduce the capital of the Company by an amount of £100,000,000. This was affected on the 29 November 2022 by a transfer of that amount from the share premium account to distributable reserves.

Ordinary shareholders are entitled to all dividends declared by the Company and to all of the Company's assets after repayment of its borrowings and ordinary creditors.

Ordinary shareholders have the right to vote at meetings of the Company. All ordinary Shares carry equal voting rights.

The nature and purpose of each of the reserves included within equity at 31 March 2023 are as follows:

- Share premium reserve: represents the surplus of the gross proceeds of share issues over the nominal value of the shares, net of the direct costs of equity issues and net of conversion amount.
- Special reserve: represents a non-distributable reserve totalling the amount of outstanding creditors at the date of the Company's approved reduction in capital.
- Capital reduction reserve: represents a distributable reserve created following a Court approved reduction in capital.
- Capital reserve: represents a non-distributable reserve of unrealised gains and losses from changes in the fair values of investments as recognised in the Capital account of the Statement of Comprehensive Income.
- Revenue reserve: represents a distributable reserve of cumulative gains and losses recognised in the Revenue account of the Statement of Comprehensive Income.

The only movements in these reserves during the period are disclosed in the Statement of Changes in Equity.

### 22. Transactions with related parties
Following admission of the Ordinary Shares (refer to note 20), the Company and the Directors are not aware of any person who, directly or
indirectly, jointly, or severally, exercises or could exercise control over the Company. The Company does not have an ultimate controlling party.
Details of related parties are set out below:
DIRECTORS
During the year, it was agreed to increase each of the Directors’ remuneration and as at 31 March 2023, Patrick Cox, Chair of the
Board of Directors of the Company, is paid a Director’s remuneration of £70,625 per annum, (2022: £57,500), Caroline Banszky is
paid a Director’s remuneration of £52,500 per annum, (2022: £45,000), with the remaining Directors’ remuneration of £43,750 each
per annum, (2022: £40,000).
Total Directors’ remuneration, associated employment costs and expenses of £242,313 were incurred in respect of the year with
£8,222 being outstanding and payable at the year end.
INVESTMENT ADVISOR
The Investment Advisor, Gore Street Capital Limited (the “Investment Advisor”), is entitled to advisory fees under the terms of the
Investment Advisory Agreement amounting to 1% of Adjusted Net Asset Value. The advisory fee will be calculated as at each NAV
calculation date and payable quarterly in arrears.
For the avoidance of doubt, where there are C Shares in issue, the advisory fee will be charged on the Net Asset Value attributable to
the Ordinary Shares and C Shares respectively.
### 86 Gore Street Energy Storage Fund plc
Financial Statements

## 22. Transactions with related parties (continued)

For the purposes of the quarterly advisory fee, Adjusted Net Asset Value means:

- (i) for the four quarters from First Admission, Adjusted Net Asset Value shall be equal to Net Asset Value;
- (ii) for the next two quarters, Adjusted Net Asset Value shall be equal to Net Asset Value minus Cash on the Company's Statement of Financial Position, plus any committed Cash on the Company's Statement of Financial Position;
- (iii) thereafter, Adjusted Net Asset Value shall be equal to Net Asset Value minus Cash on the Company's Statement of Financial Position.

During the year, the management agreement was amended to change the term of adjusted NAV to mean net asset value minus uncommitted cash. Uncommitted cash means all cash on the Company's balance sheet other than committed cash. Committed cash means cash that has been allocated for repayment of a liability on the balance sheet of any member of the group. Investment advisory fees of £4,914,324 (2022: £3,090,737) were paid during the year, there were no outstanding fees as at 31 March 2023, (2022: £nil outstanding).

In addition to the advisory fee, the Advisor is entitled to a performance fee by reference to the movement in the Net Asset Value of Company (before subtracting any accrued performance fee) over the Benchmark from the date of admission on the London Stock Exchange.

The Benchmark is equal to (a) the gross proceeds of the Issue at the date of admission increased by 7 per cent. per annum (annually compounding), adjusted for: (i) any increases or decreases in the Net Asset Value arising from issues or repurchases of Ordinary Shares during the relevant calculation period; (ii) the amount of any dividends or distributions (for which no adjustment has already been made under (i)) made by the Company in respect of the Ordinary Shares at any time from date of admission; and (b) where a performance fee is subsequently paid, the Net Asset Value (after subtracting performance fees arising from the calculation period) at the end of the calculation period from which the latest performance fee becomes payable increased by 7 per cent. per annum (annually compounded).

The calculation period will be the 12 month period starting 1 April and ending 31 March in each calendar year with the first year commencing on the date of admission on the London Stock Exchange.

The performance fee payable to the Investment Advisor by the Company will be a sum equal to 10 per cent. of such amount (if positive) by which Net Asset Value (before subtracting any accrued performance fee) at the end of a calculation period exceeds the Benchmark provided always that in respect of any financial period of the Company (being 1 April to 31 March each year) the performance fee payable to the Investment Advisor shall never exceed an amount equal to 50 per cent of the Advisory Fee paid to the Investment Advisor in respect of that period. Performance fees are payable within 30 days from the end of the relevant calculation period. Performance fees of £2,457,164, were accrued as at 31 March 2023, (2022: £1,545,369).

During the year, Gore Street Operational Management, a direct subsidiary to the Investment Adviser, provided commercial management services to the Company resulting in charges in the amount of £855,692 being paid by the Company and the SPV companies (2022: £781,600).

### INVESTMENT

The Company holds 100% interest in GSES 1 through equity and a loan facility. Transactions and balances held with GSES 1 for the year are all detailed within note 12.

## 23. Guarantees and Capital commitments

The Company together with its direct subsidiary, GSES1 Limited entered into Facility and Security Agreements with Santander UK PLC in May 2021 for £15 million. The Facility was increased to £50 million in June 2023. Under these agreements, the Company acts as charger and guarantor to the amounts borrowed under the Agreements by GSES1 Limited. As at 31 March 2023, no amounts had been drawn on this facility.

The Company had no contingencies and significant capital commitments as at the 31 March 2023.

## 24. Post balance sheet events

The Directors have evaluated the need for disclosures and / or adjustments resulting from post balance sheet events through to 14 July 2023, the date the financial statements were available to be issued.

The Board approved on the 17 March 2023, the issuance of an interim dividend of 2 pence per share. This dividend totalling £9,627,990 was paid to investors on 11 April 2023.

The Board approved on the 14 June 2023, the issuance of a final dividend of 1.5 pence per share. This dividend totalling £7,220,992 will be paid to investors on 17 July 2023.

The size of the revolving credit facility, within which the Company acts as charger and guarantor to amounts borrowed by its subsidiary GSES 1 Limited, has been increase in June 2023 from £15 million to £50 million. The term of the facility has been extended for four years to 2027.

Annual General Meeting – Recommendations

# Annual General Meeting – Recommendations

**The Annual General Meeting (“AGM”) of the Company will be held on Thursday, 21 September 2023 at 9.30 am. The formal Notice of Meeting is set out on page 90. The following information is important and requires your immediate attention. If you are in any doubt about the action you should take, you should consult an independent financial adviser, authorised under the Financial Services and Markets Act 2000.**

## Ordinary business

Resolutions 1 to 13 are all ordinary resolutions. Resolution 1 is a required resolution. Resolution 2 invites shareholders to approve the Company’s dividend policy. Resolution 3 concerns the Directors’ Remuneration Report, on pages 57 to 58. Resolutions 4 to 8 invite shareholders to elect and re-elect each of the Directors for another year, following the recommendations of the Remuneration and Nomination Committee, set out on pages 56 and 57 (their biographies are set out on pages 48 and 49). Resolutions 9 and 10 concern the re-appointment and remuneration of the Company’s auditor, discussed in the Audit Committee Report on pages 53 and 54.

## Special business

**Resolution 11:** Continuation (ordinary resolution) In accordance with the Company’s articles of association, the Directors are required to put forward a proposal for the continuation of the Company to shareholders at five-yearly intervals. The Board considers that the long-term investment objectives of the Company remain appropriate and that the current Investment Manager remains well placed to continue to deliver them over the long-term. An ordinary resolution will therefore be proposed at the AGM to agree that the Company should continue as an investment trust.

**Resolutions 12 and 13:** Directors’ authority to allot shares (ordinary resolutions)

These resolutions deal with the Directors’ authority to allot ordinary Shares of one penny each in the capital of the Company (“Shares”) in accordance with section 551 of the Companies Act 2006 (the “Act”).

If passed, resolution 12 will authorise the Directors to allot Shares up to a maximum nominal amount of £481,399, which represents approximately 10% of the Company’s issued Shares (excluding Shares held in treasury) as at the date of this report.

If passed, resolution 13 will authorise the Directors to allot further Shares, in addition to those which may be allotted under resolution 12, up to a maximum nominal amount of £481,399, which represents approximately 10% of the Company’s issued Shares (excluding Shares held in treasury) as at the date of this report.

If both resolution 12 and resolution 13 are passed, authority will be granted to the Directors to allot Shares up to a maximum

nominal amount of £962,798, which is a total of up to 20% of the existing issued ordinary share capital of the Company (excluding Shares held in treasury) as at the date of this report. The Board recognises that this authority is beyond the standard 10% authority typically sought by investment companies, but believes that the passing of both resolution 12 and resolution 13 is in shareholders’ interests given that:

- the authorities would provide greater flexibility to allow the Company to take advantage of potential investment opportunities sourced by the Company’s Investment Manager; and
- any Shares issued under these authorities will not be issued at prices less than the last published net asset value (“NAV”) per Share (adjusted for dividends) at the time of issue plus a premium to cover the costs of such issuance.

If resolution 12 is passed but resolution 13 is not passed, the Directors will only be authorised to allot up to 10% of the existing issued ordinary share capital of the Company. Resolution 13 is conditional on resolution 12, so if resolution 12 is not passed resolution 13 will not be passed either.

Each of the authorities granted pursuant to resolution 12 and 13 will expire at the conclusion of next year’s annual general meeting (unless previously renewed, varied or revoked by the Company at a general meeting).

The Directors have no present intention to exercise the authorities conferred by resolution 12 and resolution 13.

**Resolutions 14 and 15:** power to disapply pre-emption rights (special resolutions)

Under the Act, when new Shares are allotted or treasury Shares are sold for cash, they must first be offered to existing shareholders pro rata to their holdings. Each of resolutions 14 and 15 will, if passed, give the Directors power, pursuant to the authorities to allot granted by resolutions 12 and 13 respectively, to allot Shares or sell Shares from treasury for cash without first offering them to existing shareholders in proportion to their existing holdings, up to a maximum nominal amount of £481,399 which represents approximately 10% of the issued ordinary share capital (excluding Shares held in treasury) as at the date of this report, which in aggregate amounts to £962,798, which represents approximately no more than 20% of the Company’s issued ordinary share capital (excluding Shares held in treasury) as at the date of this report. The powers granted by these resolutions will expire at the conclusion of the annual general meeting to be held in 2024 (unless previously renewed, varied or revoked by the Company at a general meeting).

The Directors have no present intention to exercise the authorities conferred by resolution 14 and resolution 15. Any Shares will only be allotted or sold out of treasury without pre-emption rights applying, at a price that is not less than the latest published NAV (adjusted for dividends) together with an amount to cover the costs of any such issuance.

Annual General Meeting – Recommendations
Resolution 16: Authority to make market purchases of the
Company’s own shares (special resolution)
At the AGM held on 20 September 2022, the Company was
granted authority to make market purchases of up to 72,161,781
Shares for cancellation or holding in treasury. No shares have
been bought back under this authority and the Company
therefore has remaining authority to purchase up to 72,161,781
Shares. This authority will expire at the forthcoming AGM.
This resolution seeks authority for the Company to make market
purchases of its own ordinary shares and is proposed as a
special resolution. If passed, the resolution gives authority for the
Company to purchase up to 72,161,781 of its ordinary shares,
representing 14.99% of the Company’s issued ordinary share
capital (excluding treasury shares) as at the date of this Notice of
AGM. The resolution specifies the minimum and maximum prices
which may be paid for any ordinary shares purchased under
this authority. The authority will expire at the conclusion of the
Company’s next annual general meeting. The Directors do not
currently have any intention of exercising the authority granted
by this resolution. The Directors will only exercise the authority
to purchase ordinary shares where they consider that such
purchases will be in the best interests of shareholders generally
and when they are trading at a discount to the underlying net
asset value per Share. The Company may either cancel any
Shares it purchases under this authority or transfer them into
treasury (and subsequently sell or transfer them out of treasury
or cancel them). The Company does not have any options or
outstanding share warrants.
Resolution 17: Notice period for general meetings
Resolution 17 is to be proposed as a special resolution to allow
the Company to hold general meetings (other than annual general
meetings) on at least 14 clear days’ notice. If approved, the
resolution will be effective until the end of the Company’s next
annual general meeting. The Board will consider on a case by
case basis whether the use of the flexibility offered by the shorter
notice period is merited, taking into account the circumstances,
including whether the business of the meeting is time sensitive.
### Recommendations
The Board considers that the resolutions relating to the above
items of business are in the best interests of shareholders as
a whole. Accordingly, the Board unanimously recommends to
shareholders that they vote in favour of all of the resolutions to be
proposed at the forthcoming AGM, as they intend to do in respect
of their own beneficial holdings.

9. Appointment of a proxy does not preclude you from attending the meeting and voting in person. If you have appointed a proxy and attend the AGM in person, your proxy appointment will automatically be terminated.

10. A corporation which is a shareholder can appoint one or more corporate representatives who may exercise, on its behalf, all its powers as a shareholder provided that no more than one corporate representative exercises powers over the same share.

11. If you are a person who has been nominated under section 146 of the Companies Act to enjoy information rights: You may have a right under an agreement between you and the shareholder of the Company who has nominated you to have information rights (the "Relevant shareholder") to be appointed or to have someone else appointed as a proxy for the meeting. If you either do not have such a right or if you have such a right but do not wish to exercise it, you may have a right under an agreement between you and the Relevant shareholder to give instructions to the Relevant shareholder as to the exercise of voting rights. Your main point of contact in terms of your investment in the Company remains the Relevant shareholder (or, perhaps, your custodian or broker) and you should continue to contact them (and not the Company) regarding any changes or queries relating to your personal details and your interest in the Company (including any administrative matters). The only exception to this is where the Company expressly requests a response from you. The rights relating to proxies set out above do not apply directly to nominated persons.

12. A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution if no voting indication is given, your proxy will vote or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the meeting.

13. As at 5 pm on 13 July 2023, which is the latest practicable date before publication of this notice, the Company's issued share capital comprised 481,399,478 ordinary shares of £0.01 each. Each ordinary share carries the right to one vote at a general meeting of the Company and, therefore, the total number of voting rights on that date is 481,399,478. No shares are held in treasury. The Company's website will include information on the number of shares and voting rights.

14. Any member attending the meeting has the right to ask questions. The Company must answer any question you ask relating to the business being dealt with at the meeting unless: answering the question would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information. The answer has already been given on a website in the form of an answer to a question. It is undesirable in the interests of the Company or the good order of the meeting that the question be answered.

15. Under section 527 of the Companies Act, shareholders meeting the threshold requirements set out in that section have the right to require the Company to publish on a website a statement setting out any matter relating to the audit of the Company's accounts (including the auditor's report and the conduct of the audit) that are to be laid before the AGM. The Company may not require the shareholders requesting any such website publication to pay its expenses in complying with the request. Where the Company is required to place a statement on a website under section 527 of the Companies Act, it must forward the statement to the Company's auditor not later than the time when it makes the statement available on the website.

16. Under section 338 of the Companies Act 2006, Shareholders meeting the threshold requirements set out in that section, may, subject to conditions, require the Company to give to shareholders notice of a resolution which may properly be moved and is intended to be moved at that meeting. The conditions are that: The resolution must not, if passed, be ineffective (whether by reason of inconsistency with any enactment or the Company's constitution or otherwise). The resolution must not be defamatory of any person, frivolous or vexatious. The request: may be in hard copy form or in electronic form; must identify the resolution of which notice is to be given by either setting out the resolution in full or, if supporting a resolution sent by another shareholder, clearly identifying the resolution which is being supported; must be authenticated by the person or persons making it; and must be received by the Company not later than 10 August 2023, which is at least six weeks before the meeting.

17. Under section 338A of the Companies Act 2006, shareholders meeting the threshold requirements set out in that section may, subject to conditions, require the Company to include in the business to be dealt with at the meeting a matter (other than a proposed resolution) which may properly be included in the business (a matter of business). The conditions are that: The matter of business must not be defamatory of any person, frivolous or vexatious. The request: - may be in hard copy form or in electronic form; - must identify the matter to be included in the business by either setting it out in full or, if supporting a statement sent by another shareholder, clearly identifying the matter which is being supported; - must be accompanied by a statement setting out the grounds for the request; - must be authenticated by the person or persons making it; and - must be received by the Company not later than 10 August 2023, which is at least six weeks before the meeting.

18. Copies of the letters of appointment of the non-executive Directors are available for inspection at the Company's registered office during normal business hours and at the place of the meeting from at least 15 minutes prior to the meeting until the end of the meeting.

19. Voting on all resolutions will be conducted by way of a poll. As soon as practicable following the meeting, the results of the voting will be announced via a regulatory information service and also placed on the Company's website.

economic activities. The investments underlying the remaining portion of this financial product
do not take into account the EU criteria for environmentally sustainable economic activities.
Any other sustainable investments must also not significantly harm any environmental or social

### 96 Gore Street Energy Storage Fund plc
SFDR ANNEX IV
### How did this financial product consider principal adverse impacts
### on sustainability factors?
During the reporting period, the fund assessed and monitored the principal adverse impacts on
sustainability factors as follows:
Greenhouse gas emissions
The fund excludes any investments in fossil fuels.
Biodiversity
The Investment Manager assesses the fund’s assets’ impact on biodiversity during the investment
and construction process and takes appropriate action to avoid or remediate impacts to ensure
compliance with local planning regulations.
Pollution and waste
The Investment Manager works closely with its partners during the construction process and over
the lifecycle of the fund’s assets to avoid pollution and waste where possible.
Human rights, social and employee matters
The fund supports the UN Global Compact Principles and OECD Guidelines for Multinational
Corporations and does not tolerate any form of forced labour, child labour or severe human rights
abuses in its supply chains. As part of the due diligence process, suppliers are required to provide
details of their supply chain management approach and to confirm, on an annual basis, compliance
with the principles outlined in the Investment Manager’s supplier code of conduct. The Investment
Manager also has processes in place to ensure health & safety standards are met on-site.
Monitoring of PAIs
Although the fund anticipates fully monitoring and reporting on all relevant principal adverse
impacts, data may not be fully, or in part, available on one or more of the fund’s investments.
In instances where data is not fully available, the Investment Manager may make reasonable
estimates as to the impact or rely on third party providers’ data to do so. In situations where data is
not appropriate to rely available either in full or in part and where the Investment Manager deems it
on estimates, the Investment Manager will explain in the fund’s reporting the rationale for such
estimation.
The table below summarises the fund’s performance as reported against the principal adverse
impacts considered. The assessment included all assets in operation and under construction held
by investee companies of the fund during the period of 1 April 2022 to 31 March 2023.

### social characteristics during the reference period?
During the reporting period, the fund expanded its operational capacity by 25.8%, from 231.7 MW
to 291.6 MW, by successfully completing the construction of the Porterstown asset in the Republic
of Ireland and through the acquisition of three operational assets (Snyder, Westover and
Sweetwater) in Texas, USA.
The fund also closed acquisitions totalling 514.7 MW of additional capacity and entered two new
grids (ERCOT and CAISO, both in the USA), thereby supporting the energy transition across
different jurisdictions.
Additionally, the Investment Manager managed the operational assets on behalf of the fund to
ensure they remain functional and continue to provide a range of services to the grid, achieving
over 95% availability over the reporting period. These services enable a higher penetration of
renewable energy sources and help to balance demand and supply, thereby avoiding carbon
emissions from fossil fuel-fired peaker plants.
