The world’s biggest wind farm is being planned off England’s south coast.

The development comprises 200 turbines, each the height of a skyscraper and spread over an area the size of Glasgow, reports the Daily Telegraph.

The planned wind farm, which is three to four times bigger than any previously built, is expected to earn its Dutch owners Eneco more than a quarter of a billion pounds a year($39bn) in subsidies alone.

A full planning application for the Navitus Bay wind farm is expected next year with the decision process taking a further 18 months.

Eneco’s preplanning report suggests each turbine could be as high as 670 feet – taller than the Gherkin skyscraper in London – and as close as eight miles to the coast. Eneco claims it will provide power for anywhere between 500,000 and 800,000 homes.
