Grid stability
Balancing reserves and a millisecond response that helps maintain power-system frequency.
How it works
How the Raseiniai energy storage system works.
Over the course of a day, the battery can switch operating modes several times — storing energy when supply is abundant and delivering it during periods of highest need.
