Financial Performance: A Year of Strategic Growth
Gore Street Energy Storage Fund (GSF) delivered a complex but strategically significant year. The NAV per share settled at 102.8p, a 4% dip from March 2024’s 107.0p. This movement primarily reflects updated third-party revenue forecasts and inflation pressures, contributing a negative impact of 7.1p per share. However, this was partially offset by a solid 5.2p boost from net portfolio returns and a 3.2p uplift from asset de-risking. Crucially, the NAV total return (including dividends) for the period was a positive 1.1%, bringing the total return since IPO to an impressive 48.0%.
Operational revenue stood at £35.3m, generating £21.0m in EBITDA from an average operating capacity of 408.9 MW. While down from the prior year’s £41.4m revenue, this performance occurred against a backdrop of significant capacity expansion and evolving market dynamics across its five grids. The average revenue achieved was £9.85 per MW/hr (£86,000 per MW/yr).
Shareholders will receive a regular dividend of 4.0p per share for the year. More excitingly, a special dividend of 3.0p per share is slated for H2 2025, funded by the substantial proceeds from the sale of US Investment Tax Credits (ITCs).
Operational Surge: Doubling Capacity and Securing Long-Term Cash Flows
The standout achievement was the more than doubling of energised capacity to 921.4 MWh (753.4 MW). This leap was powered by the successful energisation of three major assets:
- Big Rock (California): 200 MW / 400 MWh, secured with a lucrative 12-year Resource Adequacy contract generating over $14 million annually.
- Dogfish (Texas): 75 MW / 75 MWh.
- Enderby (GB): 57 MW / 57 MWh, the portfolio’s first transmission-connected asset in GB.
This expansion materially de-risks the portfolio and significantly boosts the revenue-generating asset base, now exceeding 750 MW operational across GB, Ireland, Germany, Texas, and California. Fleetwide availability remained robust at over 95%.
Strategic Moves: Monetisation, Dividends, and Realigned Fees
GSF executed several strategic plays enhancing shareholder returns and cost efficiency:
- ITC Monetisation: Secured ~$84 million (net) from selling ITCs for Dogfish (TX) and Big Rock (CA) assets – exceeding guidance. Dogfish proceeds are in; Big Rock proceeds are being received in tranches (50% already received).
- Special Dividend: The Board, following shareholder consultation, confirmed the 3p special dividend funded by Big Rock ITC proceeds, payable in two 1.5p instalments by end-2025.
- Fee Reduction: Effective 1 October 2025, the Investment Manager’s fee structure is revised:
- Management fee now based on 50% Adjusted NAV + 50% Market Cap (capped at 1% of NAV).
- Performance fees and exit fees removed entirely.
Based on FY24/25 averages, this would have saved shareholders ~£1.14m (c.22%).
- Debt & Flexibility: Ended the period with £30.5m cash, £56.3m undrawn debt headroom, and look-through debt at £112.6m (17.8% GAV). The Santander RCF was upsized to £100m.
AI Trading: GSET Outperforms the Market
A key differentiator emerged: Gore Street Energy Trading (GSET), the in-house AI-driven optimisation platform. Managing 68% of the GB portfolio by period-end, GSET outperformed the Modo benchmark by 11%. This bespoke system uses neural networks and real-time re-optimisation, demonstrating the tangible value of internalised, tech-savvy management focused on maximising BESS revenue while considering asset health.
Independent Review & Future Capital Allocation
Facing a persistent share price discount, the Board commissioned Alexa Capital for an independent strategy review. Key outcomes and capital allocation priorities include:
- Asset Enhancement: Prioritising augmentation of GB assets (Stony, Ferrymuir, potentially Enderby) from 1-hour to 2-hour duration (cost: £18-22m). This aligns with market shifts valuing longer-duration assets for trading.
- Dividend Policy Shift: Transitioning to dividends aligned with project cash flows/EBITDA. Guidance is for 0.75p per share quarterly starting Q3 (Sept 2025), with potential upside if merchant revenues recover. The target steps up to a minimum 3p annually as the portfolio reaches full run-rate capacity.
- Debt Paydown: Using the first Big Rock ITC tranche to reduce the project debt from $90m to $60m.
The review broadly endorsed the Company’s existing capital allocation strategy while identifying actionable value-enhancement opportunities like the duration extensions.
ESG Impact: Storing Sunshine, Avoiding Emissions
GSF’s operational portfolio delivered concrete environmental benefits during the year:
- Avoided 11,970 tonnes of CO2e emissions.
- Stored 39,290 MWh of renewable electricity – enough to power approximately 14,500 UK homes for a year.
A dedicated FY24/25 ESG and Sustainability Report will be published in early September, providing further detail on the fund’s approach and metrics.
Outlook: Building the Bridge
FY26 is positioned as a “bridging year.” While base dividend guidance (0.75p quarterly) reflects conservative merchant revenue assumptions and timing delays on new assets, the foundations are solid. The energised portfolio is substantially larger and more diversified, long-term contracts provide revenue certainty, costs are being actively managed downwards (fees, capex trends), and strategic asset enhancements are underway. The $84m ITC monetisation provides immediate capital for shareholder returns (special dividend) and debt reduction.
The Board and Investment Manager express confidence that as the prioritised portfolio reaches full operational capacity and cash flows mature, coupled with potential market recovery and strategic actions identified by the review, the stage is set for stronger, sustainable dividends and a potential re-rating. The focus remains on disciplined capital allocation, cost control, leveraging technology (like GSET), and extracting value from the existing geographically diversified portfolio.
