SemperPower, Corre Energy and PowerField launch large-scale Netherlands BESS projects


A double-header of Netherlands news, with SemperPower and Corre Energy planning a 640MWh BESS at the latter’s compressed air energy storage (CAES) site and Powerfield commissioning the country’s largest co-located project.

SemperPower and Corre Energy target 640MWh BESS

The pair of companies have formed a 50:50 joint venture (JV) to build a 320MW/640MWh battery energy storage system (BESS) at the same site as Corre’s CAES project in Groningen, Netherlands.

It would require capex of around €300 million (US$325 million) of which €7 million is being invested in the early-stage development already, with Corre’s share already deployed. Final investment decision (FID) is being targeted for late 2025 with a commercial operation date (COD) expected in 2026.

SemperPower, which is owned by investor Return Energy, is the owner and operator of the Netherlands’ two largest operational BESS units. It will provide battery infrastructure sourcing, development and operational expertise and finalise offtake agreements and project financing, having done so for its two projects already. The JV is targeting a fixed 10-12 year offtake with no market revenue risk.

The combined CAES and BESS will create a multi-duration energy storage project which Corre may model at its other sites. It is developing large-scale projects internationally with the most advanced of these in Netherlands and Germany- we interviewed the company earlier this year (Premium access). The firm is primarily a project developer, focusing on CAES up until now.

PowerField commissions country’s largest PV co-located BESS

Independent power producer (IPP) PowerField has put a 52MWh BESS at a PV plant into operation, the largest co-location in the Netherlands, it claimed. Concurrent with that it has launched a new business unit, PowerField Energy, which will sell solar energy into the electricity grid.

The company is aiming to have 1GWp of solar and 2GWh of energy storage in the Netherlands by 2028, alongside EV charging points via subsidiary PowerGo.

The solar and storage project in Wannepervee combines 28MWp of solar with a 52MWh BESS. It is developing a 12MWh project near another of its solar PV plants, in Emmen.

Grid operator Enexis and PowerField have agreed a time-bound contract for the projects in Wanneperveen and Emmen, whereby PowerField will have flexible access to the electricity grid when transport capacity is available. At times when there is insufficient grid capacity available, the BESS stores the electricity generated by the PV plants.

It comes amidst the Dutch government announcing grants for co-located projects starting in January 2025, as reported recently by

The flurry of triple-digit-megawatt BESS project news in the Netherlands, following announcements by Lion Storage and Giga Storage last month, come after the government provided clarity on a ‘flexibilisation’ of grid fees. In an interview with, research firm Aurora said this could boost the grid-scale energy storage market substantially (Premium access).
