Munich, 09 July 2025

The installation, located in the Greater Poland – Wielkopolska – region, will have a storage capacity of 241 MWh and is scheduled to begin commercial operations in 2027.

Under the agreement, Axpo will handle the commercial management and optimisation of the system. It will apply its experience in managing flexible energy assets across Europe. The financial structure includes a floor and revenue-sharing model.

The deal is one of the first of its kind between private-sector entities in Poland’s energy storage sector claims Axpo. Therfore the company expects the innstallation to serve as a benchmark for similar projects in Central and Eastern Europe.

Poland’s grid problems are well known, which is why the project is intended to be seen as part of efforts to stabilize the Polish power grid. The BEES concept is in line with the country’s efforts to modernize the grid and integrate renewable energy.
