November 14 (Renewables Now) - Swedish energy group Vattenfall on Monday said it is seeking views from local residents on its latest plans for the proposed Thanet Extension offshore wind farm in the UK, which involve turbines up to 250 metres (820 ft) high.     

Currently there are no turbines of that height on the market but Vattenfall thinks they will become available by the time of installation in the early 2020s.

The proposal is for up to 34 turbines with assumed capacity of 10 MW and 12 MW, and total capacity of up to 340 MW. The project would extend the existing 100-turbine, 300-MW Thanet offshore wind farm off the coast of Kent, southern England.

Vattenfall presented plans for the extension in early 2017. It is now set to launch a statutory consultation on the Preliminary Environmental Information Report (PEIR), which outlines a "maximum design envelope." It expects to file a final proposal with the Planning Inspectorate next spring.

"We think we pose an interesting question: what is the right balance of turbine numbers and height? Fewer and taller or more but smaller?," said Helen Jameson, Vattenfall's project manager for Thanet Extension. She also said the goal is to have the wind farm up and running by end-2021.
