Northland Power Inc. has announced the acquisition of 100% equity interests in two battery energy storage system (BESS) projects totaling 300 MW and 1.2 GWh in Poland. The Toronto-based company acquired the projects from Greenvolt Power Group sp. z o. o., a global developer of renewable energy projects, as announced on November 20, 2025.

Project Details and Locations

The two acquired projects are Mieczysławów, with a capacity of 200 MW and 800 MWh, and Kamionka, with a capacity of 100 MW and 400 MWh. Both projects feature four-hour duration systems and are located in western Poland. The projects are currently in late-stage pre-construction phase, with financing and the start of construction expected in 2026.

The estimated total cost for both projects is EUR 200 million. Once operational, the projects will be among the first BESS facilities operating in Poland, marking a significant milestone in the country's energy infrastructure development.

Revenue Structure and Market Participation

A portion of the projects' revenue is secured through 17-year capacity auction contracts indexed to inflation. Additional revenue streams are expected from energy arbitrage and participation in ancillary services markets, providing multiple income streams for the battery storage facilities.

This revenue structure reflects the evolving nature of Poland's electricity markets and the growing need for large-scale battery storage solutions as the country transitions its energy mix.

Strategic Context and Market Transformation

The acquisition strengthens Northland's growing presence in Poland, which the company considers a core market. According to Aurora research cited in the announcement, Poland's power system is undergoing rapid evolution as it shifts from predominantly coal-based generation toward renewables. Solar PV and wind capacity in Poland is projected to increase from approximately 31 GW today to 139 GW by 2050.

Christine Healy, President and Chief Executive Officer of Northland, stated that “This acquisition marks an important milestone in advancing Poland's energy transformation and expanding Northland's portfolio in a core market. Battery storage is essential to enabling a reliable, lower-carbon energy system, and these projects represent a strong strategic fit with our growth ambitions.”
