Engie Zielona Energia said Friday it has completed the acquisition of a special purpose vehicle developing a 438 megawatt battery energy storage project in central Poland, expanding the French energy group's storage portfolio in the country.
The project initially developed by Mithra Energy and Futureal Investment Partners, and located in Trebaczewo, in Poland's Lodz Voivodeship, is expected to reach ready-to-build status in the fourth quarter of 2026, with commissioning scheduled for the first quarter of 2029.
The storage system will be directly connected to the power station, which Engie said would help reduce pressure on local transmission infrastructure and improve power reliability in the region.
Engie's Poland Country Manager Piotr Rogoz noted that large-scale storage was a priority for the company, given its importance for a modern, renewables-based economy.
The company currently has over 10.7 gigawatts of energy storage capacity in operation, or under construction globally, and during July and August alone, it added a combined 1.1 GW or 3.3 GWh of additional capacity via acquisitions, construction starts and new project comissioning.
It said that it was targeting a combined 95 GW of installed renewable energy generation and energy storage capacity by 2030.
