Baltic Power, a joint venture between Poland’s ORLEN Group and Canada’s Northland Power, has completed installation of all 78 monopile foundations for its offshore wind turbines and substations, concluding the main foundation works for what will become Poland’s first operational offshore wind farm.

The installation campaign involved over 20 vessels and more than 500 crew members and contractor representatives. The operation was carried out under challenging sea and weather conditions, using heavy components weighing up to 1,700 tonnes and stretching 100 metres long, leaving little room for error in what were often single-attempt lifts and piling operations.

Specialised vessels handled lifting and piling, supported by a fleet of tugboats, crew transfer boats, and environmental monitoring ships. To limit underwater noise and vibration from the main hammer during piling, the installation area was encircled by a double bubble curtain – a mitigation measure that is increasingly standard on large offshore wind projects in sensitive marine environments.

With all monopiles now in place, Baltic Power is finalising installation of the remaining transition pieces and is making steady progress on installing 15 MW turbines. The next major phase is offshore cable installation, including export and inter-array cables, although this work is highly weather-dependent, particularly in periods of sub-zero temperatures and severe winter conditions, noted Senior Project Director and Board Member Jens Poulsen.

Located about 23 kilometres off the coast near Choczewo and Łeba, the 1.2 GW Baltic Power wind farm spans 130 square kilometres. Once operational in late 2026, it is expected to generate around 4 TWh of electricity annually – equivalent to 3% of Poland’s current power demand.
