Four power transformers and other high-voltage components have been delivered to the onshore transformer station for the Baltica 2 offshore wind farm, marking progress on the grid infrastructure needed to operate the 1.5-gigawatt project, developers PGE and Orsted said.
The equipment delivery represents a key milestone in building the onshore connection that will link the offshore wind farm in the Polish Baltic Sea to the national power grid.
“The delivery of the power transformers, and previously also other power components, not only marks the achievement of a significant milestone in the construction process of the Baltica 2 onshore substation,” said Bartosz Fedurek, chief executive officer of PGE Baltica. “It was also, above all, a complex logistical operation involving a ship, the ports of Gdynia and Władysławowo, tugboats, a barge, and special multi-axle wheeled vehicles capable of transporting oversized cargo.”
After arriving at the port of Gdynia, the transformers were transported by sea to Władysławowo and then moved overnight to the substation site in Osieki Lęborskie. Each transformer weighs about 360 tonnes, the companies said.
The onshore substation will play a central role in managing the project’s electrical systems. “From the onshore substation, we monitor and control the entire electrical infrastructure, including offshore substations and wind turbines located approximately 40 km offshore,” said Ulrik Lange, managing director of the Baltica 2 project at Orsted.
“Together with PGE, approximately 50 of our engineers planned, designed, and helped build the electrical infrastructure to ensure a reliable energy source,” Lange added.
GE Vernova has supplied shunt reactors for the project, while a consortium of GE Vernova and Polimex Mostostal is responsible for equipping the 275-kilovolt and 400-kilovolt switchgear buildings. Testing and commissioning of the onshore station are scheduled for 2026 and 2027.
Construction work is also continuing on a six-kilometre cable route, including horizontal directional drilling, to connect the onshore infrastructure with the offshore section of the wind farm.
