Offshore works have started on Poland’s Bałtyk 2 and Bałtyk 3 wind farms, developed by Equinor and Polenergia, with the two projects set to install 100 turbines and deliver 1.4 GW of total capacity.
The developers said on 17 February 2026 that the 2026 offshore campaign will cover the installation of 100 monopiles, transition pieces (TPs), offshore substation components, subsea cables, and supporting infrastructure. More than 20 vessels are planned to be involved in 2026.
The opening activity began in January with subsea rock installation carried out by Van Oord, which deployed four vessels for the seabed scope.
From spring, the programme is scheduled to move into heavy transport and installation. Monopiles, TPs and selected components for the two offshore substations are set to be installed using Heerema Marine Contractors’ heavy-lift vessel Thialf. In the months that follow, the developers plan to continue with export cable and inter-array cable installation.
Turbine installation is planned for 2027, together with offshore substation outfitting. The developers expect the first electricity in 2027, with full commercial power production scheduled for 2028.
Onshore support capacity is progressing alongside the offshore schedule. Equinor’s operations and maintenance base in Łeba, intended to coordinate vessel traffic and offshore operations during construction, is to be completed and commissioned this year.
Bałtyk 2 and Bałtyk 3 are in Poland’s exclusive economic zone in the Baltic Sea, about 37,000 m and 22,000 m from the coastline near Ustka and Łeba. The projects will deploy 100 Siemens Gamesa SG 14-236 DD turbines.
Monopiles and transition pieces are being manufactured by Sif and Smulders. Iemants, a Smulders subsidiary, is responsible for the design and construction of the two offshore substations.
