Polish grid operator Polskie Sieci Elektroenergetyczne (PSE) said its transmission infrastructure is technically prepared to accept electricity from the country’s first offshore wind farms in the Baltic Sea.
PSE said the newly built Choczewo substation, the expanded Żarnowiec substation and the 400-kilovolt transmission line linking the two facilities are ready to transmit power from planned offshore projects.
Tests carried out on primary and secondary equipment at the Choczewo station confirmed its ability to receive electricity, the company said. Additional specialised measurements on the 400kV Choczewo–Żarnowiec line also confirmed that voltage parameters meet technical requirements.
At the Żarnowiec station, work included connecting two new bays to the busbars and conducting voltage tests to ensure readiness for offshore wind integration.
“The completed tests confirm the technical readiness of the infrastructure to receive energy from offshore wind farms,” PSE said in a statement.
The operator said the transmission line and substations will remain in trial operation until all construction work is completed and the required permits are obtained.
PSE added that it is developing broader grid infrastructure in northern Poland, including the construction of two substations and more than 250 kilometres of high-voltage transmission lines, to support the growing share of renewable energy in the power system.
