East Anglia 3 installs UK’s longest offshore wind turbine blade in installation milestone
Masdar and ScottishPower install a record 115m blade at East Anglia 3 offshore wind farm, delivering clean power for 1.3 million homes and billions in UK investment.
East Anglia 3 marked a major offshore milestone this month with the successful installation of the first wind turbine fitted with a record‑length 115‑metre blade. The operation, led by partners Masdar and ScottishPower Renewables with manufacturer Siemens Gamesa, places the project at the forefront of the UK’s wind energy expansion. The turbine is one of 95 planned for the site off the Suffolk coast and represents a step change in turbine scale and generation capacity.
Record-sized blade installed at East Anglia 3
The newly installed blade measures 115 metres from root to tip, surpassing the previous UK record by seven metres. All 285 blades for the 95‑turbine East Anglia 3 array are being produced at Siemens Gamesa’s Hull facility in the UK. Project teams noted the blades’ unprecedented size visually exceeds the length of a standard football pitch, underscoring the scale of modern offshore technology.
Turbine specifications and expected output
Each turbine at East Anglia 3 is rated at 14 megawatts with a rotor diameter of approximately 236 metres and a tip height reaching about 262 metres. Project modelling indicates a single rotation can generate meaningful household energy equivalents, illustrating how larger rotors translate into higher yield. Once operational, the wind farm is expected to supply clean electricity to about 1.3 million UK homes, making it one of the most productive assets in the developers’ portfolios.
UK manufacturing and supply‑chain impact
Siemens Gamesa’s Hull factory is manufacturing the full complement of blades for the project, supporting a workforce of more than 1,400 employees at the site. Developers say the project will channel billions of pounds into UK supply chains and create thousands of jobs during construction, alongside more than 100 permanent roles in the east of England. The domestic manufacturing footprint is being positioned as a critical element in securing local economic benefits from offshore wind deployment.
Partnerships and leadership perspectives
East Anglia 3 is a joint effort by Masdar, ScottishPower Renewables and Iberdrola, reflecting a multinational investment partnership in UK renewable infrastructure. ScottishPower Renewables described the blade installation as a significant engineering and commercial milestone for the partners, and Masdar highlighted the achievement as further proof of offshore wind’s maturation in the British market. Siemens Energy representatives also emphasised the factory’s role in workforce development and training to sustain long‑term sector growth.
Installation vessels and operational logistics
The turbine was lifted into place using Cadeler’s heavy‑lift vessel Wind Osprey, a class‑O installation ship designed for offshore turbine assembly. Developers confirmed that a newer class‑P installation vessel from Cadeler will join operations later in the month to accelerate commissioning activities. Project logistics balance large‑scale component delivery, specialist installation vessels and coordinated supply‑chain movements to maintain a steady construction tempo at sea.
Energy security and regional economic benefits
Project backers say East Anglia 3 will strengthen UK energy security by adding a substantial, predictable source of zero‑carbon electricity to the grid. Beyond generation, the scheme is expected to stimulate regional supply chains in East Anglia and contribute to national decarbonisation targets. Officials emphasise the combined environmental and economic returns as central to policy and private investment decisions in offshore renewables.
The East Anglia 3 milestone signals a new phase for UK offshore wind characterised by larger rotors, higher per‑turbine outputs and deeper domestic manufacturing ties. With further turbine installations planned in the coming months, partners will focus on completing commissioning and integrating the farm into the national grid while monitoring supply‑chain and workforce needs as construction scales up.
