Kentish Flats Extension
In May 2010, Vattenfall was offered the opportunity to extend Kentish Flats Wind Farm by The Crown Estate, which leases the seabed on behalf of the UK Government to wind farm developers like Vattenfall.
Vattenfall assessed the feasibility of the project and decided to seek consent from the Planning Inspectorate (formerly IPC) for an extension to Kentish Flats.
Vattenfall then began extensive discussions and consultation with the local community, local authorities and statutory consultees regarding the extension of Kentish Flats Offshore Wind Farm.
On 19 February 2013 Vattenfall was granted consent by the Planning Inspectorate to extend the 30-turbine scheme up to 17 turbines providing an additional maximum installed capacity of up to 51MW.
This means that the extension itself will be capable of generating between 90,000 megawatt hours and just over 150,000 megawatt hours (MWh) of clean electricity every year, which is equivalent to the total annual electricity needs of between 20,000 UK households and 35,000 UK households*. The extension will be constructed more than 7km from shore and will cover nearly 8 sq km.
When completed, Kentish Flats, as a whole, will be capable of generating between 350,00MWh and just over 430,000MWh of clean electricity every year, which is equivalent to the total annual electricity needs of between 82,000 UK to 96,000 UK households.
Due to the size of the infrastructure, the application was considered by the National Planning Inspectorate. Public hearings took place in May last year and, after consideration, the Inspector submitted his recommendation to the Secretary of State. The Secretary of State has now considered this recommendation and as mentioned above, gave consent on 19 February 2012.

The 90MW Kentish Flats has been generating green electricity since 2005. Find out more about this project by visiting:
Kentish Flats Offshore Wind Farm
*This is calculated in the following way:
Number of hours in the year: 8760
Installed capacity: 30 to 51MW
Average industry capacity factor for offshore wind: 35%
Average annual UK household electricity consumption: 4,478 kilowatt hours (kWh)
For example: (8760 x 30 x 35%) x 1000 = 91,980,000kWh divided by 4,478 = 20,540 homes.
