Baltic Power installs Poland’s first offshore 15 MW wind turbine in milestone for national energy transition

The Baltic Power project, a joint venture between ORLEN Group and Northland Power, has successfully installed the first of 76 offshore wind turbines — each rated at 15 MW — in the Polish part of the Baltic Sea. This marks the beginning of full-scale installation for what will be Poland’s first offshore wind farm and one of the first in Europe to deploy next-generation 15 MW turbines.

Once fully operational in 2026, Baltic Power will deliver approximately 1.2 GW of installed capacity, generating around 4 TWh of renewable electricity annually — equivalent to 3% of Poland’s total electricity demand. The wind farm is expected to power more than 1.5 million households and reduce CO₂ emissions by approximately 2.8 million tonnes per year compared to conventional sources.

The installation is being carried out by Wind Osprey, a 160-metre jack-up vessel operated by Cadeler. Specially upgraded in 2024 with 1,600-ton cranes and a 160-metre lifting height, the vessel is capable of transporting and installing three complete turbines per trip — including nacelles, blades, and tower sections.

Each Vestas V236-15.0 MW turbine features blades measuring 115 metres in length, with a swept area exceeding 43,700 m² — roughly the size of six football fields. The towers exceed 120 metres in height, with the total structure, including foundations, reaching approximately 260 metres. Notably, Baltic Power is the first project globally to use tower sections made from recycled steel.

- Today marks a key milestone not just for Baltic Power, but for the entire Polish offshore wind sector, said Grzegorz Szabliński, CEO of Baltic Power. - We’re pioneering new engineering standards, logistics coordination, and domestic manufacturing — with nacelles built in Szczecin and other components sourced locally. We’re setting the pace for future projects.

In addition to turbine installation, foundation works — including monopiles and transition pieces — are ongoing across the offshore site. Preparations for inter-array and export cable installations are underway, with offshore substations scheduled for installation in autumn 2025. Onshore infrastructure, including the grid connection point and substation, is progressing according to schedule. A service base in Łeba, completed in April, will support operations and maintenance for the next 30 years.

Baltic Power is currently the only offshore wind farm under construction in Poland, but it is laying the groundwork for further development. ORLEN Group, as part of its long-term strategy, plans to expand its offshore portfolio up to 5.5 GW. Offshore wind is positioned as a key pillar of Poland’s energy transition — providing scalable, predictable, and clean power while reducing dependence on fossil fuels.
