Gore Street Capital and Trina Storage, Trinasolar’s energy storage unit, have formed a partnership that commits Trina to invest in Gore Street’s EU-focused private BESS fund.
The two revealed the partnership during the Energy Storage Summit 2026 in London this weeka month after the GS EU Fund SCSp and its key investors were first announced by Gore Street.
Trina Storage will contribute its systems expertise, execution capacity and long-term technical delivery, the announcement said.
The announcement also revealed that the company is targeting a total size of €1 billion (£874.92 million), including primary commitments and co-investments, by the end of 2026. In terms of activity, it is targeting the long-term deployment of 12 GWh battery energy storage systems (BESS) across the continent.
The fund’s first signing of projects is expected mid-year, with first project deliveries scheduled for the fourth quarter of 2026, Trina said.
Gore Street Capital is a fund manager and advisor, best known for the UK-focused Gore Street Energy Storage Fund (GSF). GSF has invested mainly in Britain and Ireland, with a handful of smaller assets in Germany and Texas, plus one 200MW/400MWh system in California.
However, Britain’s listed BESS funds are struggling to maintain share prices amid significant earnings volatility. Another, the Harmony Energy Income Trust (HEIT), was sold and delisted in 2025 (to asset manager Foresight)and its advisor Harmony Energy subsequently established a private, Europe-focused BESS fund.
