Gore Street’s EU Fund Reaches Second Close with Backing from the Kingdom of Spain

Press Release
12 Nov 26

Gore Street is pleased to announce that GS EU Fund SCSp (“GS EU” or the “Fund”) has completed a second close. This follows the Fund’s first close in December 2025 and reflects continued investor support for European battery energy storage, and for GS EU’s growing portfolio and pipeline. The Fund is targeting a final close in H1 2027.

GS EU acquires, constructs and manages battery energy storage systems (“BESS”) across the EU member states. To date, the Fund has committed €147m across a portfolio of 550 MWh of storage capacity, including two assets in the Republic of Ireland, acquired in August 2026, and one in Poland, signed in September 2026. The Fund is also progressing a further 255 MWh of advanced stage opportunities, with additional acquisitions expected before year-end.

GS EU’s cornerstone investors include the European Investment Fund (“EIF”) and the National Treasury Management Agency, as controller and manager of the Ireland Strategic Investment Fund (“ISIF”). At the second close, the Fund welcomed a new commitment from the Kingdom of Spain through the C&I Instrument under the National Recovery and Resilience Plan, as well as further support from private capital.

Alex O’Cinneide, CEO of Gore Street, said:

“Completing our second close reflects strong institutional support in European energy storage and for our ability to deliver it at scale. We are delighted to welcome the Kingdom of Spain as an investor, alongside material follow-on commitments from our existing investors. We are already putting this capital to work where storage is needed most in Ireland and Poland, and advancing further opportunities in Spain and Romania.”
