Gore Street Capital

What Gore Street Capital does

Gore Street Capital is a London-headquartered private investment manager founded in 2015 that specialises exclusively in battery energy storage system (BESS) assets. The firm manages approximately 1.4 GW of operational and contracted capacity across six energy markets (United Kingdom, Ireland, Germany, Texas, California, and Japan) through three fund vehicles: the London-listed Gore Street Energy Storage Fund (LSE: GSF, UK-listed since 2018), the Tokyo Energy Storage Investment Limited Partnership (Japan's first grid-scale storage fund, co-managed with ITOCHU Corporation since 2024), and the Luxembourg-domiciled GS EU Fund SCSp (targeting €500 million, first closed January 2026). Gore Street operates as a vertically integrated manager with in-house capabilities spanning sourcing, structuring, procurement, construction, asset management, and optimisation, including a proprietary Gore Street Energy Trading desk that employs algorithmic and multi-service revenue strategies across approximately 78.5 MW onboarded at launch.

The firm's revenue model is fee-based, comprising recurring management and advisory fees on assets under management and advisory (c.£615m+ today) plus performance fees tied to fund outcomes. Gore Street sells fund interests to institutional investors, sovereign wealth funds (e.g., European Investment Fund, Ireland Strategic Investment Fund, Tokyo Metropolitan Government), family offices, and listed fund shareholders on the LSE. Distribution is direct and relationship-driven across both listed (GSF) and private (Japan, EU) channels. The core technology stack includes an in-house trading desk with over 15 years of optimisation experience, algorithmic trading methods (notably deployed in the German market to capture high-frequency revenue), and advanced component-level asset monitoring for predictive maintenance and warranty compliance.

Gore Street is regulated by the UK Financial Conduct Authority (FRN 1018207) through its subsidiary Gore Street Investment Management Limited, authorised on 31 March 2025. Its competitive position rests on first-mover advantage in listed energy storage (GSF was the UK's first pure-play listed energy storage fund), demonstrated revenue outperformance through geographic diversification (GSF portfolio delivered £15.1/MW/hr vs GB average of £6.1/MW/hr), and high-quality institutional investor partnerships spanning EIF, ISIF, TMG, and major Japanese corporates.
