The Iberdrola Group, through its subsidiary ScottishPower, has installed the first wind turbine at the East Anglia THREE offshore wind farm, setting a new standard in the UK energy industry.
The turbine features 115-meter blades, the largest deployed to date in British waters.
This development positions the project as a benchmark for large-scale offshore infrastructure deployment, in line with the growing demand for clean energy in Europe.
About East Anglia THREE
Each of the 95 planned wind turbines will have a capacity of 14 MW and will be equipped with three blades manufactured by Siemens Gamesa. In total, the wind farm will incorporate 285 blades, each longer than a professional football field.
In addition, the turbines will reach nearly 300 meters in height and a rotor diameter of 236 meters, maximizing wind capture and optimizing power generation. According to project estimates, each full rotation of a turbine can generate enough electricity to power a home for more than four days.
Furthermore, East Anglia THREE will have an installed capacity of 1,400 MW, enough to supply power to more than 1.3 million homes in the United Kingdom. This will make it Iberdrola’s largest offshore wind farm and one of the most powerful globally.
The project, located in the North Sea off the coast of Suffolk, will play a significant role in strengthening energy security and reducing emissions from the UK power system.
Investment, employment, and value chain
Likewise, the initiative involves an approximate investment of £4 billion and includes long-term contracts that ensure financial stability, including contracts for difference awarded by the UK Government and a PPA signed with Amazon.
During the construction phase, the development has generated more than 2,300 jobs, and it is expected to maintain around 100 permanent positions during operation.
The installation of the first wind turbine was carried out using the jack-up vessel Wind Osprey, operated by Cadeler, with Wind Pace to join in subsequent phases of the project.
In addition, East Anglia THREE has included Masdar as a partner since 2025, as part of a strategic alliance that strengthens international cooperation in renewable energy.
