TenneT has awarded a contract to the GE Vernova–Seatrium consortium to deliver the offshore converter platform for the 2.2 GW BalWin5 offshore grid connection in the German North Sea. This marks the consortium’s fourth contract under the five-year framework agreement signed in 2023 and its first involvement in TenneT’s 2 GW projects in Germany.

Under the contract, Seatrium will design, construct, transport, and install the offshore converter platform, with most fabrication taking place at its Singapore and Batam yards. Work is scheduled to start on 1 January 2026. GE Vernova’s Electrification Systems business will provide the full HVDC technology and both the onshore and offshore converter stations.

The BalWin5 connection will feature an offshore converter station in the North Sea, an onshore converter station at Bremen-Werderland, and a combined 325-kilometre cable system. Commissioning of the project is planned for 2032. One of the connected wind farms will be the 1 GW N-9.4 site, recently secured by TotalEnergies. Earlier this year, LS Cable & System, Jan De Nul, and Denys were awarded the supply of HVDC cables for the project.

The BalWin5 project is part of TenneT’s ongoing efforts to expand Germany’s offshore wind transmission capacity and support the country’s renewable energy and decarbonisation goals.
