Seatrium, GE Vernova and TenneT have marked the start of construction of the 2GW Nederwiek 2 offshore platform with parallel steel-cutting ceremonies in Singapore and Batam.
Project director Michiel Cadenau said the milestone reflects growing activity across TenneT’s programme, with three platforms of its 2GW design now under construction.
He added: “We expect 2026 to be even busier than the previous year with now 3 platforms of our 2GW design under construction in the portfolio.”
The first two units in the Seatrium–GE Vernova consortium’s series, IJmuiden Ver Beta and IJmuiden Ver Gamma, held strike-steel events in September 2024 and May 2025 respectively.
Once commissioned in 2029, grid connection for IJmuiden Ver Beta will enable 2GW of offshore wind to be delivered from the North Sea to the Dutch onshore grid.
The HVDC transmission system will take power from the wind farm to the offshore converter platform via 66kV alternating-current links.
The converter station will then convert the power to direct current and transport it along a 525kV cable route to Maasvlakte Rotterdam, where it will be converted back to alternating current for injection into the high-voltage network.
