Ørsted and PGE are moving ahead with full-scale offshore construction activities on their Baltica 2 project by successfully installing the first foundations in the Polish Baltic Sea. With this project, the two companies are building Poland’s largest offshore wind farm, 1.5 GW. During the installation process, which is being carried out by Van Oord, 111 monopiles will be installed, 107 as foundations for wind turbines and 4 for the offshore substations. The installation process is scheduled to continue until Q4 2026.
The monopiles for Baltica 2 are about 100 metres long, with a diameter of more than 10 m, and weigh 1500 tonnes on average. Once installed offshore, these structures are designed to support wind turbines for up to 30 years in harsh marine conditions. Each monopile has a unique geometry tailored to its specific location.
The wind farm will be built, owned, and operated in a 50/50 partnership of Ørsted and Poland’s largest energy company, PGE Polska Grupa Energetyczna. The array, which will be located 40 km off the Polish coast near Ustka, is expected to be fully commissioned in 2027.
The wind array will consist of 107 Siemens Gamesa 14-222 wind turbines each rated at 14 MW, to be installed by Cadeler and Fred. Olsen Windcarrier, while Van Oord will be installing the foundations. The Port of Gdańsk will provide the base for the storage, pre-assembly, and offshore installation of wind turbine components.
Baltica 2 has a 25-year inflation-protected contract for difference (CfD) in place with the Polish state. The wind farm has obtained all permits and has signed a grid connection contract with the Polish transmission system operator, PSE.
