Kentish Flats Offshore Wind Farm
Kentish Flats is an offshore wind farm located approximately 8.5 to 13 km north of Herne Bay and Whitstable in Kent.
It is comprised of 30 3MW Vestas turbines that are expected to generate more than 280 GWh of green electricity every year, which is equivalent to the total annual electricity need of more than 61,000 UK households.
The Kentish Flats Wind Farm set a dual record at the time of its erection in 2005: The wind turbines were the largest installed in the UK, and it was also the largest wind farm in the country.
The site for the Kentish Flats Offshore Wind Farm is a large, flat and shallow plateau approx 60 kilometres east of central London.
The wind farm is arranged in a regular grid of five east-west rows each of six turbines, sited in an area of 10 km2 just outside the main Thames shipping lanes. The spacing between each turbine and rows of turbines is 700 meters.
The generated electricity is fed into the electricity network via a sub-station at Herne Bay for use in the national grid.
The site is easily accessed from the local maintenance port at Whitstable, which is only 30 minutes away by boat. The water depth is on average five meters.
