LEAG Launches 100-MW Battery Storage Project in Germany

• LEAG breaks ground on the BigBattery Oberlausitz—a game-changing 100-MW facility set to power 40 homes in 1.5 hours, paving the way for a sustainable energy future.

LEAG, a German energy company, has commenced construction on its BigBattery Oberlausitz project, a 100-MW/137-MWh battery storage facility at the Boxberg power plant in Saxony. Scheduled to become operational in 2025, the facility is designed to supply electricity equivalent to the annual demand of approximately 40 households within 1.5 hours and will be twice as powerful as its 54-MWh sister plant, BigBattery Lausitz, which opened in 2020.

The BigBattery Oberlausitz will feature two components of 50 MW each, housed in over 400 compact containers using lithium iron phosphate batteries. This initiative aligns with LEAG’s ambition to develop a gigawatt-scale battery storage park in Lusatia, transforming the former mining region into a green energy hub.
