The Bystra Battery Energy Storage System is a 6,000kW energy storage project located in Bystra, Pomerania, Poland.

The electro-chemical battery energy storage project uses hybrid as its storage technology. The project was announced in 2017 and was commissioned in 2020.


The key applications of the project are frequency regulation, renewable energy integaration, electric energy time shift and power system protection.

Contractors involved

Hitachi and Showa Denko have delivered the battery energy storage project.

Additional information

New Energy and Industrial Technology Development Organisation (NEDO0 contracted a consortium of Japanese companies to provide technology and expertise to implement the project, namely Showa Denko Materials, which manufactured and supplied the 1MW/0.47MWh of lithium and 5MW/26.9MWh of lead acid batteries; Hitachi, which made and supplied the battery energy storage system’s distribution control system as well as Hitachi ABB Power Grids, which supplied 6 MW of power conversion system (PCS) equipment. Along with the support of the Polish Ministry of Climate, local project partner companies were also involved, including state-owned transmission system operator Polskie Sieci Elektroenergetyczne (PSE) and electric power distribution company Energa. PSE will control the hybrid system.
