Battery energy storage system in the Kaunas hydropower plant

Lietuvos Energijos Gamyba has started preparations for 1 megawatt energy storage system installation in Kaunas Algirdas Brazauskas’ hydropower plant. Using a unique algorithm, the system would allow to provide a high-quality frequency containment reserve (FCR) service, compensating the asymmetries in hydro-unit operations, and would become the first and the biggest innovation of this kind in the Baltic States. Due to the growing demand for autonomous FCR services in the Baltics, the innovative energy storage system may be later adopted for the much larger hydro-units in the Kruonis pumped storage plant.
