Battery energy storage

Decarbonization | Flexibility & storage

Using a unique algorithm, the storage system would allow to provide a high-quality frequency containment reserve (FCR) service, compensating the asymmetries in hydro-unit operations. As for today, the service in the Baltics is mainly provided by the Russian power plants, operating in the post-soviet BRELL energy ring.

Although the installation of 1 megawatt energy storage system would become a pilot project in the region, high capacity (20 megawatts or more) lithium-ion batteries for large-scale grid energy storage already gained popularity in the USA, Australia, and part of the Western Europe. 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.

Currently, a potential project for battery energy storage is evaluated.
