Polish utility selects LG Energy Solution to build 900 MWh battery

Polish utility PGE Group has selected local unit of Korean battery maker LG Energy Solutions as the contractor for the 263 MW/ 900 MWh Zarnowiec battery energy storage project.

PGE Group’s tender, which was launched in July 2024, attracted only two offers. LG’s bid was selected as the most advantageous with a price of PLN 1.555 billion ($384 million) beating Corab’s bid priced at PLN 2.4 billion.
On Wednesday, Dariusz Marzec said that the selection of the general contract was a key step in the implementation of the Zarnowiec project. He also said the the BESS facility won a contract in the capacity market auction for 2029 – a procurement exercise which has catalyzed gigawatts of battery storage projects in the country.
Once commissioned in 2029, the Żarnowiec project will help balance the output of onshore and offshore wind farms and enhance the stability of the Polish electricity grid.
