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