PGE Group to build 200-MW battery storage in northern Poland

Polish state-owned power company PGE Group (WSE:PGE) is planning to build a battery energy storage system (BESS) of at least 200 MW/820MWh which will be linked to an existing pumped-storage power plant in the north of Poland.

The project has obtained the first license promise in Poland for electricity storage, PGE said in a press release.

The storage system will be set up at the 716-MW Zarnowiec pumped-storage power plant with 3,600 MWh of storage capacity. The hybrid system will be capable of supplying power to about 200,000 households for at least five hours.

Located about 10 km from the Baltic Sea, the planned storage facility will help balance the integration of renewable energy, including PGE's own solar farms as well as onshore and offshore wind parks. The power producer operates the 100-MW Lotnisko wind farm located nearby and has three locations off the Polish coast with potential for a total of 3.5 GW of offshore wind turbines.

For the implementation of the project, PGE is seeking EU funding and partners to co-finance the investment.

The Zarnowiec storage system will help PGE Group reach its goal of having 800 MW of installed storage capacity in Poland by 2030.
