East Anglia ONE

ScottishPower Renewables has connected the East Anglia ONE offshore wind farm to the UK’s electricity grid. With a capacity of 714MW, the windfarm will be fully operational and producing clean, renewable energy in 2020.

First power generated at East Anglia’s largest offshore windfarm

East Anglia ONE has now successfully generated power. The first commissioned turbines are producing clean energy, which is being transferred to the windfarm’s onshore substation in Burstall, near Ipswich in Suffolk. Over a third of the turbines have now been installed, with more being transported out by the Sea Installer vessel from Great Yarmouth every week, each of which will be gradually connected to the grid.

East Anglia ONE is one of the largest offshore windfarms under construction and once fully operational in 2020 will have an installed capacity of up to 714MW, 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.

£25million has been invested in a state-of-the-art new operations and maintenance base at Lowestoft Port, delivering 100 long-term skilled jobs, with thousands of supply chain operators using the site and nearby facilities for the lifespan of the windfarm. A further £5million was co-invested in Great Yarmouth Port to prepare the facility for construction and assembly of the turbine components. 

£70million has been committed to suppliers across the East of England, delivering jobs and investment to local communities.

 

 

Technical features of East Englia ONE

  • East Anglia ONE is sited 43km off the coast and will cover an area of 300km2, the equivalent of 40,000 football pitches
  • It will feature 102, 7MW Siemens Gamesa turbines. Once installed, each turbine will reach a tip height of 167 metres above the sea (almost twice the height of Big Ben), each consisting three 75-metre fibre glass blades, a nacelle, and a 90 metre-high tower, manufactured respectively in Hull, Cuxhaven, and Cambeltown
  • Each turbine stands on a 65-metre-high three-legged jacket foundation manufactured and assembled by Navantia in Spain, Lamprell in the United Arab Emirates and Harland & Wolff in Belfast
  • The offshore substation, fabricated by Navantia, collects the power from each turbine via the 66kv array cables, produced by JDR in Hartlepool and used on a UK windfarm for the first time
  • Two offshore export cables, each around 85 km in length, manufactured by Nexans in the UK, transfer the electricity to shore
  • These cables are connected to six onshore underground cables, each of around 37km in length and manufactured by Prysmian in France, which will transfer the electricity from landfall to the onshore substation

East Anglia ONE

One of the biggest renewable installations in the world

 In 2009 ScottishPower Renewables was awarded rights to develop offshore capacity off the coast of East Anglia as part of the Crown Estate’s Round Three Programme. East Anglia ONE is the first of four windfarms planned for the area. The second in the pipeline is East Anglia THREE, which is received planning consent in August 2017 from the Department for Business, Energy & Industrial Strategy (BEIS). East Anglia THREE is located 69km off the East Anglian coast, and will supply electricity to over one million homes. This project will be followed by two further windfarms, East Anglia TWO and East Anglia ONE North, with the Development Consent Applications being submitted in Autumn 2019.  

The four East Anglia windfarms have a total potential power capacity of up to 3.8GW, becoming one of the largest renewable energy installations in the world.

Through East Anglia ONE ScottishPower Renewables is delivering a better future, quicker.


*Based on the following calculation: 714 MW (installed capacity) x 0.3836 “offshore wind” average load factor (Digest of UK Energy Statistics) x 8,766 hours (hours per year)/3,781 KWh (average domestic annual consumption) = 634,997 homes powered equivalent
