If the Kentish Flats extension goes ahead it could use up to 17 of Vestas' new V112 3MW turbine. The projecct, which came online in 2005, currently uses 30 V90 turbines.
Vattenfall said the UK's Infrastructure Planning Commission is expected to make a decision on whether the extension goes ahead in 2013. Until then the turbine will not be completed.
Separately Vestas has chosen its president for Central Europe Hans Jörn Rieks to head up its offshore division. Rieks has been with Vestas for 18 years although he has not previouslty worked in the offshore division.
The news follows the departure of Vestas vice president offshore Anders Søe Jensen as part of recent restructure of the company.
