Gore Street Energy Storage Fund plc

(the "Company" or "GSF")

Appointment of Non-Executive Director

Gore Street Energy Storage Fund, the internationally diversified energy storage fund, is pleased to announce that Simon Merriweather has been appointed as a new Non-Executive Director of the Company, 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.

Simon is a seasoned non-executive director with significant industry and investment experience and considerable experience within infrastructure asset management. He currently serves as Senior Advisor and Investment Committee Member at infrastructure fund GLIL Infrastructure LLP, and as a Non-Executive Director at the Bristol City Leap Energy Partnership, a pioneering public-private joint venture dedicated to decarbonising the City of Bristol and its surrounding region.

Simon has over 25 years of experience in developing, building, operating, and managing major infrastructure projects worldwide and has also previously held non-executive director roles on 20 different infrastructure investments across a wide range of sectors. Most recently in an executive capacity, he was Global Head of Infrastructure Asset Management at Partners Group, where he oversaw and optimised investments across onshore and offshore wind, solar, power networks, and fibre infrastructure spanning Europe, North America, Asia, and Australia.

Prior to this, as Managing Director of Centrica PLC's Power Generation division, Simon was responsible for developing, constructing, and operating a portfolio that included eight gas-fired power stations alongside onshore and offshore wind assets. Prior to that, he served as Managing Director of Generation at EDF Energy, managing a 5 GW fleet of coal and gas-fired plants supplying approximately 6% of the UK's electricity demand.

Simon began his career with Ernst & Young, qualifying as a Chartered Accountant (ICAEW). He is a Fellow of the Institute of Directors and holds a First-Class BSc (Hons) in Applied Physics from the University of Hull.

It is confirmed that there are no other details to be disclosed concerning Mr Merriweather under UK Listing Rule 6.4.8.

Board Composition

This appointment reflects the orderly Board refreshment process underway, which was previously disclosed in the Company's 2024 Annual Results, and is part of good corporate governance protocol. The ongoing Board refreshment will see the replacement of four Board members who have been in place since IPO with duly skilled, independent individuals of the highest calibre. Simon's appointment is the result of a thorough search process led by a third-party search agency that has been working closely with the Nomination and Remuneration Committee.

Patrick Cox, Chair of the Company, said: "We are pleased to welcome Simon to the Board. His appointment reflects our commitment to ensuring the Board continues to evolve in line with the Company's growth and strategic direction. As the Company approaches its eighth anniversary, the Remuneration and Nomination Committee has taken a structured approach to strengthening the Board's collective expertise. Simon brings deep global infrastructure experience that will support the Company's ambitions. Following a period of transition, Simon will succeed Thomas Murley, who will remain on the Board for an appropriate handover period. Further updates to the Board refreshment process are expected in due course."
