Swedish developer Vattenfall has revealed the latest designs for its 1.8GW Norfolk Vanguard offshore wind farm off the east coast of the UK.
The company today published the results of initial survey work in its preliminary environmental information report, which will inform the project’s final design plans.
Vanguard will feature between 90 and 257 turbines between 7MW and 20MW.
The developer said it is still mulling a range of foundation types for the project including jackets, monopiles, gravity base, suction caisson and even floating designs.
The report includes plans for up to six offshore export cables that will bring power to shore just south of Happisburgh.
The company will apply for consent do deploy either HVDC or HVAC technology and are still working to refine the project’s 200-metre wide, 60km-long onshore cable corridor.
Vattenfall has narrowed the possible locations for onshore HVAC booster stations to two sites, one at Ridlington, the other east of Crostwright.
The project will connect to the National Grid at the Necton substation in Norfolk which will need to be enlarged to handle the extra capacity, the developer said.
It will run formal consultations between 7 November and 11 December ahead of submitting a Development Consent Order to the UK Planning Inspectorate next summer.
