In the Austrian federal state of Carinthia, the second phase of the Arnoldstein-Gailitz energy storage facility has been commissioned, making it the largest battery storage system in the country, with a capacity of 22 megawatts (MW) and 44 megawatt-hours (MWh).
The company NGEN Group was entrusted with the construction of the facility for Austrian Power Grid (APG) – the national transmission system operator. The purpose of this installation is to stabilize the power grid at the high-voltage level.
This project enables the balancing of grid loads and the storage of surplus energy generated during periods of high renewable energy production.
