The Kentish Flats Offshore Wind Farm is a wind farm located off the coast of Kent, England on a large, flat and shallow plateau just outside the main Thames shipping lanes. The wind farm is operated by Vattenfall.


The distance from the nearest wind turbine to Whitstable is 6.2 miles (10.0 km). The nearest turbine is 5.5 miles (8.9 km) away from Herne Bay.

Construction was completed in August 2005, with commissioning and testing of all turbines completed by September 2005. The wind farm consists of 30 Vestas V90-3MW wind turbines with a total nameplate capacity of 90 MW.[1] Turbines were installed by the Danish offshore wind farms services provider A2SEA.[2] Between 2007 and 2010, the capacity factor was around 30%.[3]

Kentish Flats extension[edit]

In February 2013 Vattenfall was granted consent to extend the existing Kentish Flats Offshore Wind Farm.[4] 15 turbines each with a capacity of 3.3 MW were installed adding an extra 49.5 MW to the wind farm.[5] Offshore construction began in October 2014 and was operational by December 2015.[5][6]
