- £4bn East Anglia THREE: 95 × 14MW turbines (1.4 GW) to power ~1.3 million homes.
- All 285 blades are 115 m long and UK-manufactured by Siemens Gamesa in Hull.
- Turbines reach ~262 m tip height with 236 m rotor diameters.
- Installation uses Cadeler jack-up vessels Wind Osprey and Wind Pace; construction underpins thousands of jobs and more than 100 long-term roles.
Project overview
East Anglia THREE is a £4 billion offshore wind project by ScottishPower and Masdar comprising 95 × 14MW turbines (1.4 GW) off the Suffolk coast, aiming to generate enough power for about 1.3 million homes.
Turbine and blade specifications
The first installed turbine features 115 m blades—the longest used in UK waters—mounted on a Siemens Gamesa 14MW platform with a 236 m rotor diameter and an approximate 262 m tip height; the blades are 7 m longer than the previous 108 m record.
Manufacturing and workforce
All 285 blades for the project are manufactured at Siemens Gamesa’s Hull factory, which employs over 1,400 people and supports local supply-chain activity and workforce training.
Installation
Installation is being executed by Cadeler using jack-up vessels Wind Osprey and Wind Pace operating in parallel to sustain installation pace and efficiency across the campaign.
Economic impact
Developers state the programme involves significant UK supply-chain investment, will support thousands of construction jobs and is expected to create more than 100 long-term roles in the East of England.
