The installation of all 78 foundations, or monopiles, at the Baltic Power offshore wind farm, Poland’s first 1.2 GW project, has been completed, marking a major milestone in the construction campaign. The joint venture between ORLEN Group and Northland Power is now moving to the next phase, with electricity generation from the Baltic Sea expected by the end of this year.

So far, 60 of the 78 transition pieces and 30 of the 76 wind turbines have been installed, while the offshore substations are complete, and onshore infrastructure, including cables and substations, is over 90% finished. The construction campaign is expected to conclude in the second half of 2026.

“Until now, no project of this scale has been executed in Poland. The installation of the monopiles, weighing between 1,300 and 1,700 tonnes and up to 100 metres long, required highly precise operations and coordination,” said Ireneusz Fafara, CEO of ORLEN S.A.

The monopile installation involved over 80 types of vessels, including heavy-lift cranes, tugboats, crew transfer vessels, and offshore supply ships, with more than 4,500 crew members, contractor representatives, and Baltic Power staff involved. To protect marine life, the installation area was surrounded by a double bubble curtain to mitigate noise and vibrations during pile-driving. “Installing all 78 foundations safely and with precision demonstrates our strong capabilities in executing large-scale offshore wind projects. This milestone reflects the strength of our joint teams,” said Christine Healy, CEO of Northland Power.

Located 23 km off the coast near Choczewo and ?eba and covering 130 sq km, the wind farm will generate up to 4 TWh of electricity annually, equivalent to 3% of Poland’s current national demand. Baltic Power is the most advanced offshore wind project in Poland and the first to start offshore installations.
