Greenvolt Power has connected its 200 MW battery energy storage system at Nowa Wieś Ełcka to Poland's transmission grid. The project will improve grid stability, enhance renewable energy integration and support the country's long-term decarbonisation goals.
Greenvolt Power, part of the Greenvolt Group, has successfully connected its 200 MW battery energy storage system (BESS) at Nowa Wieś Ełcka to Poland’s transmission grid, marking a significant milestone in the country’s energy transition.
Developed in partnership with BYD Energy Storage, the project forms part of a broader 400 MW/1.6 GWh energy storage programme being deployed across Poland. It is among the country’s largest battery storage investments and is designed to strengthen grid stability, improve system flexibility and facilitate the integration of increasing volumes of renewable energy.
The utility-scale BESS will store surplus renewable electricity during periods of excess generation and discharge power during peak demand, helping reduce grid congestion and minimise renewable energy curtailment. The project is also expected to enhance energy security, improve network reliability and support Poland’s long-term decarbonisation objectives.
The commissioning of the Nowa Wieś Ełcka facility highlights the growing role of large-scale battery energy storage in modernising electricity networks and enabling a more resilient, flexible and renewable-powered energy system.
