What does it take to accelerate a nation’s shift from coal to clean energy A blend of strategic investment, technological readiness, and strong market signals. Northland Power’s recent acquisition of two major battery energy storage projects in Poland marks a defining step in the country’s transition toward a more resilient, renewable powered grid. Announced on November 20, 2025, the deal strengthens Northland’s position in a rapidly evolving energy landscape where grid scale storage is becoming indispensable.
Northland Power’s acquisition of two late stage BESS developments from Greenvolt Group reinforces its commitment to Poland’s shifting energy framework. While the deal value remains undisclosed, the move aligns closely with Northland’s long term strategy to engage in Poland’s dynamic electricity market, where the need for flexible, large scale storage continues to rise. This transaction also follows Greenvolt’s April 2025 announcement of plans to sell a seven hundred megawatt storage portfolio, highlighting widespread market momentum. As Poland works to reduce its reliance on coal dominated generation, Northland’s expanded footprint supports national goals for grid modernization and cleaner energy integration.
The acquired portfolio comprises two significant projects: the two hundred megawatt eight hundred megawatt hour Mieczyslawow BESS and the one hundred megawatt four hundred megawatt hour Kamionka BESS. Both facilities are approaching the end of development and are slated for construction commencement in 2026. With a combined expected investment of approximately two hundred thirty one point two four million dollars, the portfolio represents one of Poland’s most ambitious energy storage builds to date. Designed to address grid intermittency and enhance overall system stability, these assets will play a critical role as renewable penetration increases across the country.
A portion of the portfolio’s revenue is secured under seventeen year inflation linked capacity auction contracts—covering one hundred seventy megawatts from Mieczyslawow and eighty five megawatts from Kamionka—at an annual price of PLN two hundred forty four point ninety per kilowatt. This provides stable, predictable income while the remaining capacity is optimized through energy arbitrage and participation in ancillary service markets. The structure balances reliability with market upside, positioning Northland Power for sustained returns. With DC Advisory and Green Giraffe serving as financial advisors to Greenvolt, the transaction reflects strong confidence in the long term role of BESS in Poland’s energy evolution.
Northland Power’s acquisition of these two large scale battery storage projects signals not only a strategic expansion but also a commitment to supporting Poland’s clean energy transformation. As grid demands grow and renewable capacity accelerates, advanced storage will form the backbone of reliability and flexibility across the nation.
