Polish state-owned transmission system operator, Polskie Sieci Elektroenergetyczne (PSE), has confirmed the technical readiness of its infrastructure to handle power from offshore wind farms.
“The new Choczewo station and the expanded Żarnowiec station, along with the 400 kV line connecting them, are ready to transmit energy from Baltic Sea wind farms to inland consumers,” said Włodzimierz Mucha, Vice President of PSE, on 30 December 2025.
In December, the construction contractor at the Choczewo substation, a consortium of SPIE Energy Poland and Elfeko, conducted tests confirming the facility’s readiness to receive power from Polish offshore wind farms.
On the 400 kV Choczewo – Żarnowiec line, under construction since October 2024, ElbudBis installed phase and lightning conductors and performed specialized measurements to confirm readiness for voltage supply.
Recent work at the Żarnowiec station by PSE Inwestycje, a PSE group company, resulted in two new bays being connected and voltage tests completed, indicating readiness to connect to the 400 kV line, which will soon carry electricity from offshore wind farms.
Until construction is completed and permits are obtained, the infrastructure will remain in trial operation, according to the TSO.
PSE has been preparing the national grid for offshore wind-generated electricity since 2019. Poland is advancing several offshore wind projects, including the 1.2 GW Baltic Power project by Orlen and Canada’s Northland Power, nearing completion.
When operational, the Baltic Power wind farm is expected to generate up to 4 TWh of electricity annually.
Ørsted and PGE are constructing the 1.5 GW Baltica 2, and Polenergia and Equinor are building the 1.4 GW Bałtyk 2 & 3 wind farms, expected to produce power in 2027. Baltica 2 aims for full operation by the end of 2027, and Bałtyk 2 & 3 by 2028.
Ocean Winds’ BC-Wind offshore wind farm has entered the construction phase. The 390 MW farm plans to produce power by 2028.
