The project is near the Lixhe hydroelectric power plant and will contribute to the daily balancing of the grid and to strengthening Belgium’s supply security, EDF said.

Mathieu Bihet, Federal Minister for Energy of Belgium, commented: “With 150 MW of power and 600 MWh of storage capacity, this battery storage facility brings new flexibility capacity to our electricity system. This is essential to strengthen the integration of renewable energies, better balance the grid, and ensure the security of our supply.”

Belgium was one of Continental Europe’s early movers on grid-scale storage thanks to a storage-friendly regulatory regime, particularly on grid fees, and support from TSO Elia including via a capacity market (CM) which has provided long-term revenues. Many large-scale BESS projects in Belgium have CM contracts.

Just in July, owner-operator BStor put a 50MW/140MWh project online while Netherlands-based platform Giga Storage financed a huge, 2.8GWh project, one of the largest in Europe.

EDF is active across renewables and BESS globally, but via Power Solutions specifically it put a 50MW/120MWh project in Poland online in May.
