Gore Street Energy Storage Fund plc
(the "Company" or "GSF")
Unaudited NAV
Gore Street Energy Storage Fund plc, the internationally diversified energy storage fund, is pleased to announce its unaudited Net Asset Value ("NAV") as at 30 June 2025.
Net Asset Value - June-end 2025
The Company today reports an unaudited NAV of 102.8 pence per share, after the payment of dividends, in line with the 31 March 2025 NAV of 102.8 pence per share. Accounting for the 1.0 pence dividend paid during the period, the quarterly NAV total return was 0.94%, bringing NAV total return since IPO to 49.0%.
Over the quarter, operational portfolio cash generation was £3.7m (0.7 pence per share), contributing to rollover and actuals of £4 million. Cash generation is now expected to materially increase as both Big Rock and Enderby are operational and as more assets are onboarded onto the proprietary GSET platform, which continues to outperform the market (more details below).
Unaudited movement in NAV between 31 March 2025 and 30 June 2025
NAV Movement | £ millions | Pence/share |
NAV March 2025 | 519.3 | 102.8 |
Rollover & Actuals | 4.0 | 0.8 |
COD Delay | −1.8 | −0.4 |
Operational Milestone (Dogfish) | 0.7 | 0.2 |
Dividends Paid | −5.1 | −1.0 |
Fund & Holdco Expenses & Debt Costs | −2.7 | −0.5 |
Other DCF Changes and FX Hedge | 4.6 | 0.9 |
NAV June 2025 | 519.1 | 102.8 |
The COD ("Commercial Operations Date") delay line in the table above reflects delays in the completion of Big Rock and Enderby, both of which became operational post-period. The operational milestone line captures the impact of Dogfish becoming operational, allowing for a lower discount rate to be applied in its valuation. The negative drivers of NAV over the period were the payment of dividends equal to £5.1 million (1.0 pence per share) and fund and Holdco expenses, as well as debt costs associated with the Company's RCF of £2.7 million (0.5 pence per share).
Balance Sheet Update
· As at 30 June 2025, the Group had £51.4 million in cash or cash equivalents. As at the same date, the Group had drawn £121.9 million in debt, with remaining headroom of £42.9 million.
· Post period, the Company repaid and reduced the size of its total borrowings, using the proceeds of the Investment Tax Credits ("ITCs").
· As at 31 August 2025, the Company had £101.8 million in borrowings with available headroom on the existing facilities of £41.8 million. As at the same date, the Group had £37.4 million in cash or cash equivalents.
Proprietary Revenue Optimisation Model - Further Assets Onboarded
In line with the 'Strategy and Capital Allocation Plan' announced on 30 July 2025, Gore Street Energy Trading ("GSET") has onboarded three additional assets in the ERCOT (Texas) market: Snyder, Sweetwater, and Westover to its optimisation platform. This marks GSET's entry into a second market and brings total optimised capacity to 192.3 MW/218.4 MWh, representing c.26% of the Company's energised portfolio on a MW basis.
GSET continued to outperform the Modo 1-hour benchmark in every month year to date. Outperformance figures were as follows:
Jan-25 | Feb-25 | Mar-25 | Apr-25 | May-25 | Jun-25 | Jul-25 |
24% | 4% | 6% | 18% | 15% | 25% | 62% |
Year to date outperformance over Modo is currently at c.20% (£7.45/MW/hr against £6.22/MW/hr). GSET's fees were benchmarked against the previous service providers in GB and Texas and the Board will benchmark the fees on a regular basis.
Board Refreshment
As announced on 1 September 2025, Simon Merriweather will be joining the GSF Board of Directors as a Non-Executive Director, effective from 18 September 2025. Simon will also be a member of the Audit Committee, the Management Engagement Committee, and the Remuneration and Nomination Committee.
This appointment reflects the orderly Board refreshment process underway, previously disclosed in the Company's 2024 and 2025 Annual Results. The ongoing refreshment will see the replacement of four Board members in total who have been in place since IPO with skilled, experienced and independent individuals of the highest calibre.

The AGM will be held on Thursday, 18 September 2025, at 10.00 a.m. Investors are encouraged to vote. The Board unanimously recommends that all shareholders vote FOR all the resolutions. Further information about the AGM, including how to vote, is available here.

Patrick Cox, Chair of the Company, commented:
"I am pleased to provide the NAV update for the June-end quarter, which demonstrates the benefits of the portfolio's geographic diversification. We will continue to update the market on the timings of the special dividends linked to the ITC receivables.
"Other recent strategic progress has included the appointment of Simon Merriweather as a non-executive director. Simon has significant experience in the infrastructure and energy sectors, is a seasoned NED and qualified Chartered Accountant. The work continues with the independent third-party agency in relation to succession planning, ensuring an orderly transition and the appointment of appropriately skilled directors.
