Trina Storage has announced an investment in a European Union-focused battery energy storage system (BESS) fund managed by Gore Street Capital. The announcement was made during the Energy Storage Summit 2026 held in London, where both companies outlined their plans to expand large-scale energy storage capacity across Europe.
The newly launched private fund is targeting the deployment of more than 12GWh of battery energy storage projects across key EU markets. These include Germany, Ireland, Poland, Italy, and countries in the Iberian region. The fund aims to raise approximately €1 billion by the end of 2026 to support the development and construction of these projects.
Under the partnership, Trina Storage will contribute investment capital as well as technical expertise. The company is expected to support the delivery, engineering, and execution of BESS projects under the fund’s portfolio. This collaboration combines Gore Street Capital’s experience in energy storage investment with Trina Storage’s global manufacturing and system integration capabilities.
Gore Street Capital has an established presence in the energy storage sector and has previously secured backing from institutions such as the European Investment Fund and the Irish Strategic Investment Fund. The new EU-focused fund builds on that track record and seeks to address growing demand for grid flexibility and renewable energy integration across the region.
According to statements made at the summit, project agreements under the fund are expected to be signed by mid-2026. Initial project deliveries are anticipated to begin in the fourth quarter of 2026.
Company representatives said the partnership will help accelerate the deployment of reliable and scalable battery storage infrastructure in Europe. The initiative is positioned as a strategic step toward strengthening grid stability, supporting renewable energy expansion, and enhancing long-term energy security within the European Union.
