The Danish-owned firm is applying for planning permission for the new plant at Sheerness in Kent to allow it to build turbines for offshore wind farms.
A company spokesman said the new 70-hectare facility would be capable of manufacturing a larger turbine to prepare for “serial production” in 2015 – subject to enough demand.
The move raises the prospect of the world’s largest wind turbine manufacturer significantly ramping up its presence in the UK.
Vesta, which signed an option agreement for land, said it was prepared to make the necessary significant investment in turning the option into a full lease and build the planned new production facilities, creating more than 2,000 direct and indirect jobs.
Anders Søe-Jensen, president of Vestas Offshore, said: “We have shown our intentions to make major investments and subsequent job creation, but it is evident that we don’t just jump head first into an investment of this size.
“Before our customers can provide us with the needed order pipeline, they need to see stability in the market and a long term political and regulatory certainty that ensures their business case.
He added: “Making that happen lies in the hands of the policy makers, so we are looking forward to seeing the UK government providing the best possible terms for the offshore wind industry to truly take off and the potential jobs becoming a reality.”
