At the Energy Storage Summit in London on February 24, 2026, Trina Storage announced a strategic partnership with UK-based energy storage private equity firm Gore Street Capital to accelerate battery energy storage system (BESS) deployment across Europe.

The two parties will establish a private fund dedicated to BESS projects throughout Europe. Trina Storage confirmed it will invest in Gore Street Capital’s EU BESS Fund, alongside other institutional investors including the European Investment Fund and the Irish Strategic Investment Fund, as well as several additional private institutions.

First Projects Expected in 2026

The fund’s first project agreements are anticipated by mid-2026, with initial project deliveries targeted for the fourth quarter of the year.

The newly formed fund aims to deploy more than 12 GWh of energy storage capacity, with projects expected to benefit all 27 European Union member states. The mandate includes a minimum EU exposure of 80%.

Technical Expertise and Capital Scaling

According to Gabriele Buccini, Head of Trina Storage Europe, the company will contribute its technical expertise and industry experience to support the fund’s ambitions.

“We look forward to leveraging our shared expertise and providing Trina’s technological and executional know-how to help achieve our ambitious targets. We are committed to supporting the growing demand for BESS across EU member states and Gore Street Capital in their other global ventures,” Buccini said.

He added that Trina Storage is pleased to collaborate with Gore Street Capital on what it described as the next generation of EU energy storage projects. The listed Gore Street Energy Storage Fund has demonstrated strong performance, providing confidence in the new EU BESS Fund alongside established institutional partners.

Gore Street Capital expects the total size of the fund, including co-investment capital, to reach €1 billion by the end of 2026.

Alicja Kowalewska-Montfort, Managing Director of Energy Storage at Gore Street Capital, said the firm is pleased to welcome Trina into its third dedicated energy storage fund as it continues expanding the Gore Street platform across Europe.
