EAST ANGLIA ONE OFFSHORE WIND FARM
East Anglia ONE is part of the last great offshore wind farm in the United Kingdom
With an installed power capacity of 714 MW, it will provide clean energy to almost 600,000 British homes from 2020. East Anglia ONE is the largest renewable energy project undertaken by a Spanish company ever, and entails an investment between £2,500 - £3,000 million.
East Anglia ONE: main project data.
East Anglia ONE will be the largest offshore wind farm in the world when it starts operations in 2020, thanks to its installed power capacity of 714 MW, supplying clean energy to almost 600,000 British homes. This is the largest renewable energy project undertaken by a Spanish company ever, and entails an investment between £2,500 - £3,000 million, as proof of Iberdrola's commitment to combating climate change.
ScottishPower has recently awarded a contract to the British company Murphy for the onshore cable connection works of the project with a value of approximately €14.7 million. In particular, Murphy will execute the following cable works: excavation, conduit installation, restoration and verification of locations; the works are expected to be completed by August 2018.
The size of Iberdrola's flagship project is unheard-of in the industry. These are some of the most relevant details:
- East Anglia ONE will have 102 turbines of 7 MW each one, provided by Siemens Gamesa. They will be the largest ones to date.
- The turbines will be hosted inside wind turbine towers reaching a total height of 235 metres.
- The wind farm will be located 85 km from the coast and occupy an area of 300 km2, the equivalent to 40,000 football pitches.
- The sub-station will reach a height of 158 metres, only 7 metres shorter than the Iberdrola Tower building in Bilbao.
The participation of Spanish companies in the project is remarkable. Currently, Navantia is building the marine substation in the port of Cádiz and 42 'jackets' in Fene, La Coruña. The foundation will be developed by the Asturian Windar, which is in charge of the transition pieces and the piles of the foundations.
But this new offshore wind farm is part of an even more ambitious project: Iberdrola has applied to the British Government for permission to extend these facilities and has, therefore, submitted a plan to the United Kingdom Authorities for East Anglia TWO (257 km2/800 MW capacity) and THREE (305 km2/1,200 MW capacity).
Likewise, and in response to the company's on-going commitment to wind power research and innovation, ScottishPower, the British subsidiary of Iberdrola, is developing the Frond Mats initiative (vegetation covers) in the waters of the East Anglia ONE offshore wind farm, which uses synthetic undersea vegetation to reduce the effects of currents and is designed to protect wind turbines from the effects of erosion, resulting in huge economic savings.
One of the largest renewable energy installations in the world
Through its British subsidiary, ScottishPower Renewables, Iberdrola has received the approval of the Department for Business, Energy & Industrial Strategy of the United Kingdom (BEIS) to start-up East Anglia THREE, a new offshore wind farm that will have an installed power of 1,200 megawatts (MW). Therefore, the future East Anglia wind farm will reach a total power capacity of 2,000 MW, becoming one of the largest renewable energy installations in the world.
East Anglia THREE will be located 69 kilometres off the Norfolk coast, close to the London metropolitan area, and shall supply electricity to approximately one million British homes. The aim is to start on the construction work in 2022 and start production in 2025.
Other projects under construction
Iberdrola, through its subsidiary ScottishPower Renewables is working on other offshore wind power projects, such as:
- The Saint Brieuc offshore wind farm (496 MW), located in the waters of Saint Brieuc Bay, will supply clean energy to 850,000 households after it is commissioned.
- The British Government approves the Iberdrola East Anglia THREE offshore wind power megaproject, with a 1,200 MW capacity
- ScottishPower Renewables agrees on a contract with Nexans and DeepOcean for the transmission cables for the East Anglia ONE farm
- ScottishPower Renewables agrees on a contract with Van Oord for the installation of steel jacket structures for East Anglia ONE
- Iberdrola awards a contract valued at more than EUR 120 million for its East Anglia ONE offshore wind farm to Navantia
