Trina Storage, Gore Street Capital to deliver 12 GWh of new BESS projects in Europe

At the Energy Storage Summit in London on 24 Feb. 2026, Trina Storage, the energy storage arm of Trinasolar, announced it is teaming up with UK-based energy storage private equity firm Gore Street Capital to expand Europe’s BESS footprint.

The duo is forming a private fund dedicated to BESS across Europe, with Trina Solar stating its commitment to invest in Gore Street Capital’s EU BESS Fund, joining other investors such as the European Investment Fund, the Irish Strategic Investment Fund and several other private institutions.

The Fund’s first project signatures are expected in the middle of this year with initial project deliveries targeted for the final quarter of the year.

The duo’s fund is targeting more than 12 GWh of deployments, delivering projects that will benefit the 27 European Union member states with a minimum EU exposure of 80%.

Trina Storage will provide its technical and industry knowledge to the fund, according to Gabriele Buccini, Head of Trina Storage Europe.

“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 support the growing demand for BESS across EU member states and Gore Street Capital in their other global ventures.”

The executive added: “We are extremely pleased to be joining forces with Gore Street Capital to support the next generation of EU energy storage projects. The listed Gore Street Energy Storage Fund has delivered a rare level of success, and this gives us confidence in this new EU BESS Fund, alongside prestigious partners like Gore Street Capital, the European Investment Fund and the Irish Strategic Investment Fund.”

GSC expects the overall size of the fund and co-investment to rise to €1 billion by the end of 2026. Alicja Kowalewska‑Montfort, Managing Director Energy Storage at Gore Street Capital, said the team was pleased to welcome Trina into its third dedicated energy storage fund as it continues to scale the Gore Street platform across Europe.

“This fund builds on our strong track record in originating, constructing and operating battery storage assets, supported by deep market insight and integrated construction, asset management and energy trading capabilities,” she said.

The executive added, “The EU BESS Fund is focused on delivering high‑quality projects that enhance energy resilience and system flexibility across EU member states, as we expand deployment across the region. Trina’s recently announced milestone of 6 GWh of European deliveries, worldwide presence, and in-house cell, cabinet and power-conversion system manufacturing underlines their position as a high‑quality partner and reflects the growing scale and maturity of the European storage market.”

In January 2026, Gore Street Capital announced the first successful close of its EU GS Fund SCSp, also targeting European energy storage.
