Power Driven Kent

Thanet Extension Offshore Wind Farm

Vattenfall is currently developing a proposal for an extension to the existing and operational Thanet Offshore Wind Farm in Kent. The extension would involve the addition of up to 34 turbines on the edges of the existing wind farm.

Why extend Thanet Offshore Wind Farm?

We know that extension projects can deliver many benefits: 

They can deliver lower cost renewable energy because we can benefit from: 

  • shared operations and maintenance approaches, 
  • our knowledge of constructing and operating in the area, 
  • the latest turbine technology. 

They allow us to build on our existing investment – in the local community and in a local workforce

Did you know?

With less than half the number of turbines, the extension could more than double the electricity coming from the existing Thanet Offshore Wind Farm.

Project process

The project is currently under examination by the Planning Inspectorate. If you would like to get involved or follow the process you can do so through the link below.

In Kent, we have a cluster of three offshore wind farms.

Renewable energy, like wind power, is the key to reducing global CO2 emissions.

We have decided to make the biggest leap yet to reduce the impact of climate change.
