July 15, 2021: A hybrid storage system of lead and lithium batteries storing wind-generated power has completed in Poland to form the largest battery storage system in the country, the parties involved announced on July 8.

The smart grid project was a joint effort by stakeholders in Poland and Japan, including the Sumitomo Mitsui Banking Corporation, Hitachi, Denko Showa Materials, Polish firms Polskie Sieci Elektroenergetyczne (PSE), Energa Operator SA (EOP) and Energa OZE SA (EOZE), the Polish Ministry of Climate and Environment and the Japanese government agency New Energy and Industrial Technology Development Organization (NEDO).

The project started last September, when five 1MW lead batteries and one 1MW lithium-ion battery providing a total storage capacity of just over 27MWh — the largest battery storage system in Poland, the project leaders say — was installed at the Bystra wind farm in Gdansk.

“Along with the introduction of large amounts of wind power generation in Poland, the risk of the grid destabilization and the shortage of load balancing capabilities become an issue, generating a need for a system that will stabilize the power grid while at the same time suppressing economic burden and enabling the introduction of large amounts of wind power generation and other renewable energies,” the project leaders say.
