Poland's Baltic Power offshore wind farm supplies first power to grid

On 10 July, the Baltic Power offshore wind farm in the Baltic Sea delivered its first electricity to Poland’s national power grid via the new 400 kV Choczewo substation in Choczewo, Pomerania. The substation, costing about 530 million zł and built by SPIE Energy Poland, Elfeko and other contractors, will eventually serve up to six offshore farms with a combined capacity of roughly 6 GW.

At the time of the first delivery, 54 of the planned 76 turbines were operating, giving the farm a capacity of 1.2 GW and an expected annual output of about 4 TWh – enough to supply roughly 1.5 million households, or around 3 % of Poland’s electricity consumption. The project, a joint venture of state energy group Orlen and Canada’s Northland Power, is financed partly by the National Reconstruction Plan.

Prime Minister Donald Tusk attended the connection ceremony, highlighting the milestone as a step toward greater energy security and reduced reliance on coal. The “First Power” stage will be followed by the commissioning of the remaining turbines, with full commercial operation targeted for autumn 2024‑2025, and the construction of additional high‑voltage lines to link future offshore farms.
