The installation of all 78 foundations — so-called monopiles — has been completed at Poland’s first-ever offshore wind farm. More than 20 vessels and some 500 crew members and contractor representatives were engaged in operations at the offshore construction site. Baltic Power, a joint venture between ORLEN and Northland Power, is now entering its next phase. Electricity generated in the Baltic Sea is set to flow later this year.

“Constructing an offshore wind farm represents a major logistical undertaking. The successful delivery of these unprecedented operations — in terms of both scope and scale — is a source of pride for us. No project of this magnitude has previously been executed in Poland. Crews carried out highly precise pile-driving operations, installing foundations weighing between 1,300 and 1,700 tonnes and measuring up to 100 metres in length. Completion of this stage brings us closer to our objective of supplying clean electricity from the Baltic to millions of consumers across Poland later this year,” said Ireneusz Fąfara, Chief Executive Officer of ORLEN.

The installation of the monopiles required the deployment of more than a dozen specialist vessels. In addition to the primary heavy-lift and pile-driving units, operations were supported by tugboats, crew transfer vessels, environmental monitoring ships and supply vessels. The installation zone was encircled by a double underwater air bubble curtain to mitigate underwater noise and vibrations generated by the piling hammer.

“Safe and precise installation of all 78 foundations demanded rigorous planning, coordination and specialist expertise, and confirms our capability to deliver large-scale offshore wind projects. This represents a significant milestone for the project and reflects the strength of our combined teams. Together with ORLEN, we are one step closer to supplying clean and reliable electricity to millions of households across Poland,” said Christine Healy, President and Chief Executive Officer of Northland Power.

Baltic Power Offshore Wind Farm – Construction Status

• Monopiles: 78/78 – completed

• Operations and maintenance base: completed and operational 

Since the start of the installation campaign, approximately 80 different types of vessels have been mobilised, with more than 4,500 crew members, contractor representatives and Baltic Power personnel engaged. On a daily basis, around 20 vessels operate within the 130 km² project area, coordinated by the Maritime Coordination Centre (MCC) in Łeba. Completion of the installation campaign is anticipated in the second half of 2026.

Baltic Power is the most advanced offshore wind project in Poland and the only one currently undergoing offshore installation works. Upon completion, the wind farm — with a total installed capacity of approximately 1.2 GW — will generate up to 4 TWh of electricity annually, equivalent to around 3 per cent of Poland’s current electricity demand. The site is located approximately 23 kilometres offshore, at the latitude of Choczewo and Łeba, and covers an area of roughly 130 km². Baltic Power is scheduled to enter commercial operation at the end of 2026.
