NORTHLAND'S BALTIC POWER REACHES FIRST POWER DELIVERING FIRST OFFSHORE WIND ELECTRICITY TO POLAND'S GRID

Baltic Power, Northland Power Inc.'s 1.1-gigawatt offshore wind project, owned 49 per cent by Northland and 51 per cent by Orlen -- has achieved first power, delivering the first electricity ever generated from offshore wind to Poland's national grid.

"Today, the first electricity from offshore wind flows to Polish homes and businesses -- a historic moment for the country," said Christine Healy, president and chief executive officer of Northland Power. "Northland is proud to stand with our partner, Orlen, to launch the offshore wind industry in Poland. Together we are providing a more secure, resilient energy system for generations to come, and marking the start of a new chapter in Poland's energy future."

Once operational, Baltic Power is expected to generate approximately four terawatt-hours of electricity annually -- enough to power more than 1.5 million Polish households.

Northland is playing an important role in building Poland's offshore wind sector, drawing on its world-class development and operating experience. Baltic Power demonstrates Northland's ability to deliver offshore wind projects at scale in partnership with industry and government.

Once operational, Baltic Power will add to Northland's gross installed offshore wind capacity, increasing it from approximately 1.2 gigawatts to 2.3 gigawatts and reinforcing the company's position as one of the world's leading offshore wind operators.

Northland continues its commitment in Poland through two grid-scale battery energy storage projects, totalling 300 megawatts/1.2 gigawatt-hours.

Construction and commissioning status

Offshore installation and commissioning activities continue, with 54 of the project's 76 turbines installed. Work is focused on completing the remaining turbine installations and commissioning, and the project remains on track for commercial operations in the second half of 2026, with costs aligned with original expectations.

Project overview

Baltic Power is Poland's first offshore wind project, located approximately 23 kilometres off the Polish coast near Choczewo and Leba and spanning 130 square kilometres of the Baltic Sea. Once complete, the project will consist of 76 Vestas turbines, each with a capacity of 15 megawatts. This is the largest turbine model available from European manufacturers, and Baltic Power is among the first wind farms in the world to install it.

The project is underpinned by a 25-year contract for difference secured from Poland's Energy Regulatory Office in 2021.
