We are advancing battery energy storage projects in Poland, with two prominent developments in Trzebinia and Kozienice, totalling 245MW of capacity.
As a key component in accelerating decarbonization efforts, battery storage is a crucial technology in adopting renewable energy sources while upholding system flexibility. Amidst Poland’s transition from traditional energy sources to a renewable-centric landscape, battery storage is well-positioned to help ensure the grid’s operability, provide the system with firm capacity and complement the intermittent nature of renewable energy.

Total capacity (MW) in the country

The 133MW Trzebinia project in southern Poland is set to become the largest battery storage facility participating in the Polish Capacity Market once batteries are integrated into the system from 2027.
The project will deploy Fluence's Smartstack™ platform – a modular, high-density system designed to enable fast deployment and optimised performance over an asset’s lifetime.

The battery energy storage system (BESS) will be located in Kozienice, in the east-central part of the country. The 112MW / 448MWh project is at the Ready-to-Build (RTB) stage, with all necessary administrative approvals, permits, and grid connection agreements in place for immediate construction.
