A 50MW/100MWh battery energy storage system, the largest in continental Europe, has been inaugurated in Belgium by developer Corsica Sole.

Energy crisis resulted in high ancillary services revenues for battery storage, with some assets earning four times more than expected.

The story behind EStor-Lux, Belgium’s biggest BESS to date.

EStor-Lux, Belgium’s battery energy storage system (BESS) at 10MW/20MWh, was officially inaugurated on Tuesday (26 April).

Google hails project to retrofit data centre with battery storage as a step towards rolling out similar solutions across global fleet.

Construction has started on what will be the largest battery storage project in Belgium at 25MW/100MWh when completed later this year.

Close to 900MW of publicly announced battery storage projects will be online in continental France by the end of next year.

Energy storage could garner a market share of one-third by 2025 for the new, pan-European automatic frequency restoration reserve (aFRR) market, which is set to launch in the middle of this year with France and Germany mutualising capacity first.

The EStor-Lux battery site in south Belgium fully launched commercial activity in December and has successfully participated in grid frequency auctions.
