Cube Infrastructure Managers has raised €150m in co-investment commitments for its joint venture solar photovoltaic (PV) and battery energy storage platform CubIKS.
CubIKS was established in 2025 by Cube Infrastructure Fund III in partnership with Dillinger Group, a German renewable energy plant developer and operator, as a buy-and-build energy-transition platform. With the latest co-investment commitments, CubIKS has raised €325m.
Co-investors included existing investors in Cube Infrastructure Fund III – Canadian pension funds and a Japanese institution – which invested via a Cube IM-managed co-investment vehicle.
Cube IM said the co-investment programme was its largest to date and brings the overall co-investment commitments for Cube Infrastructure Fund III to more than €400m.
Cube Infrastructure Fund III has fund commitments of €1.35bn and a total of €1.76 billion when including co-investments.
Saket Trivedi, partner and head of energy transition at Cube Infrastructure Managers, said: “We are proud and grateful to have received continued support from our existing investors for this latest co-investment fundraise. Their participation in CubIKS demonstrates strong confidence in Cube IM’s energy transition investment strategy and its ability to deliver scalable, high-quality renewable energy platforms in partnership with well-established and experienced developers and operators such as The Dillinger Group.”
CubIKS is Cube Infrastructure Fund III’s 13th investment. The platform targets solar opportunities across Germany and Northern Italy, with the aim of owning and operating 1GW of solar PV assets over the next five years, with co-located battery energy storage systems (BESS) “wherever feasible“, especially in Germany, the manager said.
