Energy from the Baltic Sea ready for transmission. A breakthrough moment for Pomerania

All required stations and power lines successfully passed voltage tests.
— The newly built Choczewo station, the expanded Żarnowiec station and the 400 kV line that connects them are prepared to transmit electricity from wind farms in the Baltic Sea to consumers in other parts of the country – said Włodzimierz Mucha, vice-president of PSE, responsible for the investment.

The object is capable of receiving energy
PSE has been preparing the National Power System to receive power from offshore wind farms in Pomerania continuously since 2019.
Before Christmas, the consortium of SPIE Energy Poland and Elfeko, carrying out construction works at the Choczewo station, performed tests of primary and secondary devices. These tests confirmed the technical ability of the facility to receive energy produced by wind farms in the Baltic Sea.
The electricity will flow in the coming months
On the 400 kV line connecting Choczewo with Żarnowiec, which has been under construction since October 2024, the contractor ElbudBis has completed the installation of phase and lightning conductors. At the end of December, specialized measurements were carried out, which confirmed the readiness of the line to be switched on.

Modernization works at the Żarnowiec station were recently carried out by PSE Inwestycje from the PSE capital group. In mid-December, two new bays were connected to the busbars and voltage tests were carried out. This means that the facility is prepared to connect a 400 kV line, which will carry energy from offshore wind farms in the coming months.
One of PSE's largest investments
Until all construction works are completed and the necessary permits are obtained, the station and transmission infrastructure operates in trial operation mode.
In the north of the country, PSE is implementing one of the largest investment programs in its history. As part of the extraction of power from renewable energy sources, the company is building two new power stations and over 250 km of high-voltage lines, as well as modernizing the existing network. There are also plans to build further facilities for a future nuclear power plant in the region.
