In May 2010 the Crown Estate (owner of the seabed) offered Vattenfall the opportunity to extend the Kentish Flats Wind Farm. After assessing the feasilbity of this project, Vattenfall proposes to extend the existing wind farm along its western and southern edges with 10 to 17 turbines (depending on their size). This would add up to 51 MW of additional capacity. The Extension would generate up to 150,000 megawatt-hours (MWh) of green electricity every year. This is equivalent to the total annual electricity needs of up to 35,000 UK households.
The Extension would be located approximately 7.8 km from the shore and cover approximately 7.77 sq km.
Vattenfall requires a Development Consent Order (DCO) in order to build and operate the Extension and has applied to the Infrastructure Planning Commision for the DCO.
Before submitting the application, Vattenfall undertook detailed preparatory work and since October 2010 has held extensive discussions with the local community, consultees such as Canterbury City Council, Natural England and stakeholders, including local fishermen. The formal community consultation period was 31 January 2011 to 4 March 2011. All comments received on the proposed application were carefully considered by Vattenfall in finalising the Extension proposal.
