Wind Energy – Nederwiek
Seatrium, GE Vernova and TenneT recently celebrated the strike steel for the third offshore platform of the 2GW offshore wind projects, Nederwiek 2.
On 5 February, several teams celebrated the official start of construction of the Nederwiek 2 platform in parallel ceremonies at the yards in Singapore and Indonesia.
Michiel Cadenau, project Director at TenneT said: “This moment marks another great milestone in our construction activities. We expect 2026 to be even busier than the previous year with now 3 platforms of our 2GW design under construction in the portfolio. We are looking forward to continue the good cooperation with our partners GE Vernova and Seatrium.”
The three 2GW offshore platforms of the Seatrium GE Vernova consortium are now under construction in different stages: the first project, IJmuiden Ver Beta, celebrated strike steel on 11 September 2024 and the second project, IJmuiden Ver Gamma, on 14 May 2025.
Once commissioned in 2029, the first grid connection will be ready to connect 2GW of electricity from the wind farm IJmuiden Ver Beta in the North Sea. The other grid connections will follow in the next years.
The high-voltage direct current (HVDC) transmission systems will connect the windfarm off the Dutch coast with the high voltage grid on land. The wind power produced offshore will be transported as alternating current to the offshore converter platform, using a 66-kV connection: the wind farm will be connected directly to the offshore platform. The converter station converts the alternating current into direct current.
The electricity will be transported via long innovative 525 kV cable connection to the onshore converter stations at Maasvlakte Rotterdam. Here the electricity is converted back into alternating current and fed into the high voltage grid via the converter station.
