A consortium of GE Vernova and Singapore’s Seatrium has secured a major contract from Dutch-German grid operator TenneT to deliver the BalWin5 offshore grid connection, a 2.2 GW high-voltage direct current (HVDC) transmission system designed to bring North Sea wind power to Germany’s electricity network.
BalWin5 is expected to provide enough renewable electricity to supply about 2.75 million households, forming part of Germany’s strategy to accelerate offshore wind deployment and strengthen long-term energy security.
The award marks the first German 2 GW-class project for the GE Vernova-Seatrium consortium under a five-year framework agreement with TenneT.
The BalWin5 system will include an offshore converter platform, an onshore converter station in Bremen-Werderland, and a combined 325-kilometre cable route. Commissioning is planned for 2032.
GE Vernova’s Electrification Systems division will deliver the complete HVDC technology and both converter stations, including control and protection systems designed to stabilize high-capacity power flows from distant offshore wind farms. Seatrium will design, build, transport and install the offshore platform, with fabrication to begin in 2026 across its Singapore and Batam yards.
“BalWin5 reflects the scale and ambition of Germany’s energy transition, and we are proud to support TenneT in this important program. Our Electrification Systems business brings decades
