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 of £2,800 million.

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 of £2,800 million, as proof of Iberdrola's commitment to combating climate change.

Lowestoft-based Turner Iceni, the renewable energy vessel specialist, has been awarded a contract exceeding £4 million by ScottishPower Renewables to provide support for the construction of the East Anglia ONE offshore windfarm. The scope of the contract will include the transfer of light plant, tools, spares and personnel to and from the offshore wind turbines, the offshore substation and met mast locations. Charlie Jordan, ScottishPower Renewables Project Director for East Anglia ONE, said: "We are now only a few weeks away from the first components of the windfarm being installed offshore on the East Anglia ONE project, after several months of good progress being made on the onshore cable and substation work."

Navantia and Iberdrola mark the delivery of the first jackets to Iberdrola with a ceremony on 5 March 2018. The event was attended by the chairmen of both companies, Esteban García and Ignacio S. Galán, and the chairman of the regional government Galicia, Alberto Núñez Feijóo. Pending components will be delivered in the coming months to successfully conclude the contract that both companies signed in 2016 for the construction and barge delivery of 42 jacket-type structures and 126 piles at the Fene shipyard and Windar's facilities in Avilés.

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.

On the other hand, the Port of Lowestoft, after an award of contracts valued at 10 million pounds, by ScottishPower Renewables and the Associated British Ports (ABP), has been the chosen home to carry out the monitoring of this megaproject of offshore wind. The enclave will become a new state-of-the-art base of operations and maintenance that will include specialised offices and storage. The new building will help to support the offshore phase of construction work on the windfarm, as well as the 30-plus years operational lifespan of the facility.

In total, around 100 people will be employed full-time at the port when East Anglia ONE is completed. With the support of its customers, ABP's Ports of East Anglia, King's Lynn, Lowestoft and Ipswich contribute £340 million to the UK economy every year and support 3,577 jobs in the region and 5,000 jobs nationally.

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.

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.
