East Anglia One and East Anglia Three offshore windfarms comprise of two ScottishPower Renewables projects, in addition to East Anglia One North and East Anglia Two, developed as a result of the seabed rights awarded as part of the Crown Estate’s Round 3 process.
ScottishPower Renewables has connected the East Anglia One offshore wind farm to the UK’s electricity grid.
East Anglia One has an installed capacity of up to 714 megawatts (MW), supplying enough clean, green energy to power over 630,000 homes. Located in the North Sea, 43km from the East Anglian coast, the windfarm is a joint venture between ScottishPower Renewables and Green Investment Group. The project will cover an area of 300km2, the equivalent of 40,000 football pitches.
It features 102 7MW, Siemens Gamesa turbines. Each turbine reaches a tip height of 167 metres above the sea, each consisting of three 75-metre fibre glass blades, a nacelle, and a 90-metre-high tower.
East Anglia One Limited (EAOL) was awarded a Development Consent Order (DCO) by the Secretary of State, Department of Energy and Climate Change (DECC) in 2014 for East Anglia One Offshore Wind Farm. The DCO granted consent for the development of an offshore windfarm with a capacity of up to 1200MW and associated infrastructure.
The East Anglia One project participated in the first allocation round of the Contract for Difference (CfD) scheme in 2015 and was awarded a contract for 714MW of capacity. The reduction in size of the project necessitated changes to the connection technology, a non-material change to the DCO was sought by the developer and granted in 2016.
The onshore construction works associated with East Anglia One comprise of the following, which is based on the High Voltage Alternating Current (HVAC) technology with a capacity of 714MW:
In 2021 the project was subject of a further non material change application
The East Anglia Three project is the second project to be consented in the East Anglia Zone and is wholly owned by ScottishPower Renewables.
Located 69km from the Norfolk Coast it was consented with up to 172 wind turbines, each having a rated capacity of between 7MW and 12MW, with an originally consented installed capacity of up to 1,200MW. The project will cover approximately an area of 305km2 and will have the capacity to power over one million homes.
The project shares a landfall site with East Anglia One at Bawdsey and up to four onshore underground cables, pulled through existing ducting laid by East Anglia One, will run for approximately 37km and connect to a transformer site at Bramford, Suffolk which will connect the offshore windfarms to the National Grid.
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 in December 2016.
In March 2017, the Planning Inspectorate issued a report of recommendation to the Secretary of State for Business, Energy, and Industrial Strategy (BEIS) on East Anglia Three. The Secretary of State approved the application for consent which was granted in August 2017.
The project has been subject to three non-material change applications since being consented:
