Baltic Power completes installation of all 78 offshore wind farm foundations

The Baltic Power offshore wind project, a joint venture between ORLEN Group and Northland Power, has successfully installed all 78 foundation monopiles for wind turbines and offshore substations - marking a major milestone in Poland’s largest offshore wind construction campaign.

Installation of monopiles — each weighing between 1,300 and 1,700 tonnes and up to 100 meters long — presented significant logistical and technical challenges. Every pile was custom-engineered to suit specific seabed geotechnical conditions. The campaign involved over 20 specialized vessels and close to 500 crew members and contractors, working in demanding marine and weather environments.

- The monopile installation phase was unprecedented in Poland in terms of scale and complexity, said Maciej Stryjecki, CEO of Baltic Power. - Completing this phase is a testament to the skill and coordination of our teams.

Operations included heavy-lift and pile-driving vessels supported by tugs, crew transfer vessels, environmental monitoring ships, and supply units. A double underwater air bubble curtain was deployed to minimize underwater noise and vibration during pile-driving, reflecting strong environmental stewardship.

With all monopiles now in place on the seabed, work has shifted to completing transition pieces and installing 15 MW wind turbines. Parallel efforts to lay offshore export and array cables are underway but remain sensitive to weather conditions and sea temperatures.

Project status at a glance - Baltic Power

• Monopiles: 78/78 – completed
• Transition pieces: 60/78
• Wind turbines installed: 30/76
• Offshore substations: 2/2 – completed
• Onshore substation: >90%
• Onshore cables: >90%
• Offshore export cables: 2/4
• Inter‑turbine cables: upcoming
• Service base facility: completed and operational

Since the start of the installation campaign, roughly 80 ships and 4,500 personnel have been mobilized across an area of 130 km², with about 20 vessels active daily. Activities are coordinated from the Baltic Power Marine Coordination Centre (MCC) in Łeba. Full completion of the installation phase is expected in the second half of 2026.

Once fully built, the Baltic Power offshore wind farm — located approximately 23 km off the Polish coast near Choczewo and Łeba — will have a capacity of around 1.2 GW, capable of producing up to 4 TWh of electricity annually — roughly 3 % of Poland’s current electricity demand. Commercial operation is expected by the end of 2026.
