Baltic Power, the joint venture of ORLEN and Northland Power building Poland’s first offshore wind farm, has confirmed the installation of the 50th of its 76 turbines. The mandatory phase of power and infrastructure testing is due to commence in the coming weeks, with the installation campaign expected to conclude in the second half of 2026.
“As we are installing the last remaining turbines and proceed with offshore cable works, we commence extensive test and commissioning works, leading to integration and energisation of offshore and onshore infrastructure of the farm and the first test power delivery to the national grid. These works are unprecedented in Poland,” said Maciej Stryjecki, CEO of Baltic Power.
The project is among the first two worldwide to install Vestas 15 MW turbines, currently the largest model supplied by European manufacturers. Each turbine, together with its foundation, exceeds 250 metres in height, and the swept area of its 115.5-metre blades is larger than six football pitches. Baltic Power is also the first project to use recycled steel in the top sections of multiple towers, cutting their carbon footprint by around 10%, and several nacelles have been manufactured locally in Szczecin. The installation campaign is executed by Cadeler using a jack-up vessel supported by CSOVs.
Construction is more than 80% complete. All 78 foundations and transition pieces are in place, both offshore substations and the onshore substation with its grid connection are prepared for commissioning, and the offshore cable campaign is ongoing. The service base is operational, with the first operations-phase contracts secured. “We have to ensure the utmost safety and reliability of the farm infrastructure before it becomes part of the national power system,” added Jens Poulsen, Project Director and Board Member of Baltic Power.
Once completed, the roughly 1.2 GW wind farm will generate up to 4 TWh of electricity annually, around 3% of Poland’s current demand. The farm is located approximately 23 km from the shore near Choczewo and Łeba, covering an area of 130 sq km.
