Foundation installation has been completed at the 1200MW Baltic Power offshore wind farm in Polish waters.
The joint-venture between ORLEN Group and Northland Power has installed all 78 monopiles at the array, alongside 60 out of 78 transition pieces, and 30 out of 76 turbines.
More than 20 vessels, along with 500 crew members and contractor representatives, have been involved in the offshore construction campaign.
Electricity generated in the Baltic Sea is set to be supplied to the grid by the end of this year, the joint-venture said.
Chief Executive Officer of ORLEN Ireneusz Fąfara said: “The successful delivery of these unprecedented operations – both in terms of scope and scale – is a source of pride for us.
“The installation teams carried out highly precise pile-driving operations, installing foundations weighing between 1,300 and 1,700 tonnes and reaching up to 100 metres in length.
“The completion of this milestone brings us closer to the goal of supplying clean electricity from the Baltic Sea to millions of customers in Poland by the end of this year.”
President and CEO of Northland Power Christine Healy said: “Installing all 78 foundations safely and with precision requires strong planning, coordination and expertise, and is proof of our strong capabilities executing large-scale offshore wind.
“This is a major milestone for the project, and reflects the strength of our joint teams.”
The end of the construction campaign is expected in the second half of 2026.
The project will feature 76 Vestas V236-15.0 MW turbines.
