East Anglia Hub: our biggest offshore wind project worldwide

Iberdrola group is going to build a macro offshore wind complex in UK waters, the East Anglia Hub. This undertaking will see the development of three projects capable of delivering a total installed capacity of 3,100 MW: East Anglia ONE North, East Anglia TWO and East Anglia THREE. The works, which represent an investment of GBP 6,500 billion, are to commence in 2022 and are expected to take four years.

East Anglia Hub
offshore wind complex

Iberdrola group — through its UK subsidiary, ScottishPower Renewables — is to develop the East Anglia Hub, a macro offshore wind complex to deliver a combined installed capacity of 3,100 MW. The investment cost will amount to approximately GBP 6.5 billion.

This power is sufficient to supply clean energy to 2.7 million British homes and represents more than 7.5 % of the 40 GW target for offshore wind power set by the United Kingdom Government for 2030. The East Anglia Hub will make a significant contribution to this goal, supporting green recovery regionally and nationally and helping to meet climate neutrality commitments.

Destined to become the company's biggest offshore wind project worldwide, it will encompass three developments Iberdrola already has in its portfolio in the East Anglia area, specifically, in the southern area of the North Sea: East Anglia ONE North, East Anglia TWO and East Anglia THREE. The offshore wind farms will be developed simultaneously, which will shorten construction and commissioning times, increase opportunities for the supply chain, reduce the cost of clean energy and actively contribute to the country's offshore objectives.

East Anglia THREE [PDF] — with an installed capacity of 1,400 MW — will be located 69 km off the Norfolk coast, near the London metropolitan area. This first project already has a building permit, while the remaining two — East Anglia ONE North (800 MW) and East Anglia TWO (900 MW) — have submitted planning requests, which are being analysed by the UK Planning Inspectorate. Depending on the outcome of these considerations, construction of the East Anglia Hub is expected to start in 2023 and finish in 2026.


Iberdrola, through ScottishPower Renewables, has selected Siemens Gamesa Renewable Energy (SGRE) as the preferred supplier to supply and install some of the most powerful and productive wind turbines in the world for its East Anglia Hub project. The two companies have agreed to work together on the next Contracts for Difference auction, scheduled for the end of the year, with the intention of reaching agreements for the supply and installation of turbines by then.

The selection of a preferred supplier at this time will enable Iberdrola and SGRE to join forces both in the project plan and in the design of a new-generation turbine, with 14 MW of unit power, with the aim of achieving greater efficiency and maximising opportunities for the supply chain.

The potential supply and installation of 200 turbines for the East Anglia Hub by SGRE would make it possible to replicate and maximise the achievements of the joint work carried out on the East Anglia ONE wind farm from the point of view of job creation and support of the UK supply company chain.

The Hub projects would create a pipeline of continued economic investment that will support jobs and opportunities across the East of England. SPR will continue to work closely with local authorities, groups and local colleges to maximise the potential positive outcomes for local people, building on the success of East Anglia ONE.

This development will see Iberdrola become one of the major offshore wind operators in the United Kingdom, where East Anglia ONE already operates, with a capacity of 714 MW.
