Polish state-owned energy company PGE Group announced on Friday (5 January) that it has obtained connection conditions for a battery storage facility with a capacity of 400 megawatts (MW) in Gryfino (northwestern Poland).
Conditions for connecting the Gryfino energy storage facility were issued by Polish transmission system operator PSE. The installation is to be connected to the transmission system at a voltage of 400 kV.
“The Gryfino energy storage facility will be one of the largest energy storage facilities in Europe. The planned installation will not only ensure the possibility of storing green energy during periods of increased production from wind farms, but will also strengthen the level of energy security of the national energy grid,” said Wojciech Dąbrowski, President of the PGE Management Board. “This investment brings us closer to achieving the strategic goal of the PGE Group, which is to achieve at least 800 MW in energy storage by 2030.”
Currently, PGE owns two battery energy storage facilities. In 2020, PGE inaugurated the first modular energy storage system in Rzepedź in the Podkarpackie voivodeship (southeastern Poland). The system has a capacity of around 2.1 megawatts (MW) and a storage capacity of 4.2 megawatt hours (MWh), designed to support the reliability of the local distribution network. The company launched its second energy storage system in 2021 in Góra Żar in the Silesian voivodeship (southern Poland) with a capacity of 500 kilowatts (kW) and a usable capacity of 750 kilowatt hours (kWh).
PGE is also developing a battery energy storage facility at the Żarnowiec pumped storage power plant (southern Poland) with a capacity of at least 200 MW and a storage capacity of over 820 MWh, planned for commissioning in 2027. By 2030, the company aims to have at least 0.8 GW of new energy storage capacity.
