Greenvolt Power has agreed the sale of two utility-scale battery energy storage projects in Poland, with a combined capacity of 300MW/1.2GWh.
The buyer is Northland Power, a Canada-based global power producer with a diversified portfolio of energy infrastructure assets worldwide.
The projects – Mieczysławów (200MW/800MWh) and Kamionka (100MW/400MWh) – are located in western Poland and both stand at ready-to-build stage. Designed with a four-hour storage duration, they will enhance system flexibility and deliver balancing services. Construction is expected to begin in 2026, with the facilities set to become among the first large-scale BESS installations in Poland once operational. Both have secured 17-year capacity auction contracts indexed to inflation.
This transaction aligns with Greenvolt’s asset rotation strategy, which foresees the sale of 70–80% of internally developed assets while retaining 20–30% on the balance sheet. The approach enables efficient capital allocation and supports the accelerated roll-out of solar, wind and storage projects across Europe, North America and Asia.
“This agreement demonstrates Greenvolt’s ability to develop and bring to market large-scale projects, namely in battery storage,” said João Manso Neto, CEO of the Greenvolt Group. “We have matured a strategically located pipeline that is attracting strong market interest, enabling us to execute our asset-rotation strategy, recycle capital and accelerate the deployment of clean energy projects.”
