Trina Storage will support Gore Street Capital’s Private EU BESS Fund in bringing technology expertise and execution experience.

Trina Storage, the global energy storage solutions provider and a business unit of Trinasolar, and global renewable energy leader and energy storage private equity firm Gore Street Capital (GSC) have partnered in a newly formed private fund dedicated to BESS across the EU 27. Trina Storage has made a commitment to invest in GSC’s EU BESS Fund, joining other organisations including the European Investment Fund, Irish Strategic Investment Fund, and a range of leading private sector institutions and investors. Trina Storage will bring its system expertise, execution capability and long-term technical delivery.



Announced in a presentation at the Energy Storage Summit in London on Tuesday 24 February 2026, the collaboration will see both parties work together to help advance the growth of BESS deployment in Europe, through a range of new storage projects and initiatives. With the partnerships secured to date and future commitments, GSC expects the overall size of the Fund and co-investment to rise to €1 billion by the end of this year.



The Fund’s first project signatures are expected mid-year, with initial project deliveries targeted for Q4 2026. The Fund’s goal is to deliver BESS projects that will benefit EU member states with a minimum EU exposure of 80%, and, in total, rise to over 12GWh in deployments.



Gabriele Buccini, Head of Trina Storage Europe, said: “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. 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.”

Alicja Kowalewska Montfort, Managing Director Energy Storage at Gore Street Capital, said: “We are pleased to welcome Trina into our third dedicated energy storage fund as we continue 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. 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 6GWh 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.”
