[{"type":"text","content":"\n\n21st January 2025\nGore Street Energy Storage Fund plc \n(the \"Company\" or \"GSF\") \nImproved GB Revenue and Successful Energisation of Big Rock (200 MW/400 MWh US Asset)\n \nGore Street Energy Storage Fund plc, the internationally diversified energy storage fund, is pleased to announce a portfolio update and the energisation of \"Big Rock\" - the 200 MW / 400 MWh asset in California - bringing the Company's total energised capacity to 621.4 MW / 792.1 MWh across five grids.\nTrading and Portfolio Update:\nFor the calendar year ending 31 December 2024, the Company is estimating an operational portfolio revenue of c.£37.7m (weighted portfolio average: c.£10.83/MW/hr)1 and an operational EBITDA of c.£24.5m representing an EBITDA margin of 65%.\nBased on the 2025/26 mid-case NAV revenue forecasts from several third-party providers, the annualised 12-month portfolio revenue run-rate during FY 2025/26 is estimated2 at c.£72m on 753.4 MW of operational capacity.

Dynamic Containment saw its highest average price since July 2023, a sign of the recovery of ancillary services prices in GB, reflecting a slower build-out, along with more competitive bidding strategies in the market.\nThe Investment Manager has also developed an in-house route-to-market capability and to-date has onboarded five GB assets with a combined capacity totalling 78.5 MW. Since November 2024, the GSET portfolio5 has outperformed the Modo 1-hour BESS benchmark by 19.0%.\nSuccessful Energisation of US Asset, Big Rock:\nThe \"Big Rock\" project in California is now energised, representing a 47% increase in the Company's energised capacity, which now stands a...
