Construction of the offshore substation for the East Anglia TWO windfarm has officially moved into its execution phase, as Smulders HSM, part of Eiffage Métal, advances works under an EPCIC contract awarded by ScottishPower Renewables, a subsidiary of Iberdrola Group, in 2025.
Fabrication of the offshore high-voltage substation topside is now underway at the Stormpolder yard in the Netherlands, while jacket foundation construction has been launched at the company’s Newcastle facility in the UK. This marks a key milestone following early engineering activities that began in summer 2024.
The topside structure is designed with dimensions of approximately 58 x 35 x 30 m and a weight of around 5,100 tonnes. The supporting jacket will measure about 40 x 32 x 58 m and weigh close to 3,450 tonnes.
Hans Leerdam, Commercial Director at Smulders HSM, stated that the start of fabrication reflects tangible progress toward project realization, highlighting coordinated execution across Dutch and UK facilities and the integration of UK local content into delivery.
Charlie Jordan, CEO of ScottishPower Renewables, emphasized that the construction milestone represents further advancement toward strengthening the UK’s clean energy capacity. He noted the significance of manufacturing activities taking place the project’s future operational area, reinforcing regional economic impact and supply chain engagement.
The East Anglia TWO offshore wind farm will be located in the southern North Sea, approximately 33 km from the Suffolk coast near Southwold and 37 km from Lowestoft. The project is expected to deliver up to 960 MW of installed capacity, sufficient to supply electricity to around 950,000 homes.
Installation of the jacket foundation is scheduled for 2027, with topside installation planned later the same year.
