NORTHLAND'S BALTIC POWER OFFSHORE WIND PROJECT COMPLETES INSTALLATION OF ALL 76 TURBINES

Northland Power Inc. has completed turbine installation at Baltic Power, the 1.1-gigawatt offshore wind project in Poland jointly owned by Northland and ORLEN. All 76 turbines are now installed, with over one-third currently generating power. The project is advancing through commissioning and is on track for commercial operations in 2026, with costs aligned with original expectations. Baltic Power achieved first power in July, 2026, delivering the first electricity ever generated from offshore wind to Poland's national grid.

Highlights:

• Baltic Power, Poland's first offshore wind project, completed the installation of all 76 turbines across the 1.1-gigawatt facility in the Baltic Sea.
• The project is advancing through commissioning and is on track for commercial operations in 2026, with overall costs aligned with original expectations.
• Once operational, Baltic Power is expected to generate approximately four terawatt-hours of electricity annually, providing enough clean energy to power more than 1.5 million Polish households.

The project strengthens Northland's presence in one of Europe's most attractive power markets and reflects the company's disciplined approach to developing, financing, constructing and operating large-scale energy infrastructure. With nearly two decades of offshore wind experience, Northland continues to leverage its expertise to grow a diversified portfolio positioned to benefit from electrification, energy security and increasing demand for reliable, low-carbon power.

"Installing all 76 turbines at Baltic Power demonstrates Northland's ability to safely execute complex, large-scale offshore wind projects," said Christine Healy, president and chief executive officer of Northland. "Since entering Poland in 2021, we remain committed to building the country's energy future by combining Polish expertise and ingenuity with Northland's global offshore wind experience. Baltic Power demonstrates what can be achieved when local knowledge and international expertise come together to deliver a first-of-its-kind project. As Baltic Power advances toward commercial operations, it will provide long-term contracted power to Poland's grid, strengthen the country's energy security, and support the transition to a more resilient and diversified energy system."

Baltic Power is located approximately 20 kilometres offshore in the Baltic Sea and has a total capacity of 1.1 gigawatts, underpinned by a 25-year contract-for-difference mechanism that will provide contracted revenue certainty. Once operational, Baltic Power is expected to generate approximately four terawatt-hours of electricity annually, equivalent to approximately 3 per cent of Poland's current electricity demand and enough to power more than 1.5 million Polish households.

Baltic Power is a cornerstone of Northland's multitechnology platform in Poland. Northland is concurrently constructing two grid-scale battery energy storage projects in Poland, representing a combined 300 megawatts/1.2 gigawatt-hours of storage capacity. Together, these projects reflect Northland's diversified approach to supporting Poland's energy transition.
