GE Vernova and Seatrium have secured a contract from German grid operator TenneT to deliver key components of the 2-gigawatt BalWin5 offshore grid connection in the North Sea, the companies said on Monday.
The project is designed to transport electricity from offshore wind farms to Germany’s onshore network and is expected to supply around 2.75 million households. BalWin5 marks the first 2GW project awarded to the consortium under a five-year framework agreement signed with TenneT in 2023.
GE Vernova’s Electrification Systems business will provide the onshore and offshore converter stations, as well as the full high-voltage direct current (HVDC) technology, including control and protection systems. Seatrium will design and build the offshore converter platform and oversee its transport and installation at sea.
Work is scheduled to begin on 1 January 2026, with most fabrication taking place at Seatrium’s facilities in Singapore and Batam. The project includes an offshore converter station, an onshore station at Bremen-Werderland, and a combined 325-kilometre cable system, with commissioning planned for 2032.
