East Anglia THREE Background

East Anglia THREE is the second project ScottishPower Renewables is developing in the East Anglia Zone. 


The East Anglia THREE project is the second project to be developed in the East Anglia Zone, and is wholly owned by ScottishPower Renewables. 

Public engagement on the project began in November 2012, with a series of public consultation activities taking place throughout 2013, 2014 and 2015 and an application for development consent submitted to the Planning Inspectorate in November 2015.

The application was accepted in December 2015, and an examination of the project commenced in June 2016, concluding on 28th December 2016. 

On 28 March 2017 the Planning Inspectorate issued a report of recommendation to the Secretary of State for Business, Energy and Industrial Strategy on East Anglia THREE.  The Secretary of State approved the application for consent which was granted on 7th August 2017.

In June 2019 BEIS approved a non-material change to increase the overall capacity of the windfarm to 1400 MW.
