UK storage fund Gresham House acquires SUSI Partners

UK energy storage investor Gresham House has agreed a deal to acquire Switzerland-headquartered energy transition infrastructure investment manager SUSI Partners.

The deal will expand Gresham House’s access to continental European and Southeast Asian markets, “supporting its ambition to become a leading global alternative asset management firm”, a statement said. With £2.7 billion (EUR €3.1 billion) in assets under management (AUM), the combined energy transition business will rank among Europe’s top ten energy transition asset managers by AUM.

From completion of the transaction, all SUSI Partners’ employees will join Gresham House and SUSI Partners’ CEO Marco van Daele will lead the newly combined energy transition division. Ben Guest, a managing director at Gresham House Asset Management and the lead fund manager of Gresham House Energy Storage Fund plc (GRID), will continue to lead the UK-based energy transition team and drive growth in energy storage strategies. SUSI Partners’ portfolio management leads will continue to manage current and follow-on products within the division’s equity, credit, and Asia strategies.

The transaction remains subject to customary closing conditions including regulatory approvals. Financial terms have not been disclosed.

Tony Dalwood, CEO of Gresham House, commented: “The acquisition of SUSI Partners will strengthen our ability to meet this demand across equity and credit, combining market-leading expertise with deep local knowledge in Europe and Asia. Expanding our geographic reach will also give our growing international client base access to a wider range of strategies, co-investment opportunities and tailored solutions managed by proven teams.”

Marco van Daele, CEO of SUSI Partners, said: “Joining forces with Gresham House is an exciting new chapter for SUSI Partners and allows us to take the next step in our mission to deliver attractive investment solutions generating impactful returns for our clients. The combination brings together two complementary platforms with shared values, deep sector expertise, and a strong commitment to long-term partnerships.”
