The largest battery storage project in europe is

Germany is about to become home to Europe’s largest battery storage system – a massive 1 gigawatt (GW) / 4 gigawatt-hour (GWh) project in Jänschwalde, Brandenburg. LEAG Clean Power GmbH and Fluence Energy GmbH, a subsidiary of US-based Fluence Energy (NASDAQ: FLNC), are teaming up to build the. Europe is racing to add very large grid batteries to balance rising wind and solar output. As of mid–late 2025, four utility-scale Battery Energy Storage System (BESS) projects stand out by size — each designed in the 0. The first phase of a 200 MW/800 MWh lithium-ion battery storage facility has come online in Belgium, signaling a new model for four-hour grid-scale batteries. Sungrow, global leading PV inverter and energy storage system (ESS) provider, announced the successful grid connection of the first 400MWh of ENGIE’s 200MW/800MWh battery energy storage project in Vilvoorde, Belgium.
