On December 30, Polskie Sieci Elektroenergetyczne confirmed the technical readiness of the transmission infrastructure to receive power from offshore wind farms. All the necessary stations and lines have successfully passed voltage tests.
“The new Choczewo station, the expanded Żarnowiec station, and the 400 kV line connecting them are ready to transmit energy from wind farms being built in the Baltic Sea to consumers in the interior of the country,” said PSE Vice President Włodzimierz Mucha, who is responsible for the investment.
PSE has been carrying out work in Pomerania since 2019 to prepare the National Power System to receive power from offshore wind farms.
Even before Christmas, the contractor for the construction work at the Choczewo station, a consortium of SPIE Energy Poland and Elfeko, conducted tests on the primary and secondary equipment. These confirmed that the facility is technically ready to receive power from Polish wind turbines in the Baltic Sea.
Meanwhile, on the 400 kV line between Choczewo and Żarnowiec, which has been under construction since October 2024, ElbudBis suspended phase and lightning protection cables, and in the last days of December carried out specialist measurements confirming the line’s readiness for voltage supply.
Work on the Żarnowiec station in recent months has been carried out by PSE Inwestycje, a company belonging to the PSE capital group. In mid-December, two new fields were connected to the busbars and voltage tests were carried out, which means that the station has been prepared for the connection of the 400 kV line, which in a few months will carry the first electricity from offshore wind turbines from Choczewo.
Until all construction work is completed and operating permits are obtained, the transmission and station infrastructure will remain in trial operation.
Polskie Sieci Elektroenergetyczne (PSE) is implementing one of the largest investment programs in the company’s history in the north of the country. In order to transmit power from renewable energy sources (RES), PSE is building two power stations and over 250 kilometers of extra-high voltage lines, and the existing infrastructure is being modernized. There are plans to build more substations and lines for the nuclear power plant being built in the region.
