The installation of the first turbine at East Anglia THREE marks a major milestone in scaling up low-carbon electricity generation in the UK.

Developed by ScottishPower and Masdar, the offshore windfarm features record-breaking 115-metre blades, supporting increased renewable output and improved efficiency.

Once complete, the 1.4GW project will generate enough clean electricity to power more than 1.3 million homes, significantly reducing emissions and reliance on fossil fuels.

All 285 blades are being manufactured in the UK, supporting domestic supply chains while contributing to sustainable economic growth and job creation.

The turbines, standing around 262 metres tall, reflect advances in offshore wind technology that enable higher energy yields and more effective use of wind resources.

Charlie Jordan, ScottishPower Renewables CEO said: “This is a defining moment – and a UK industry first – for ScottishPower, Iberdrola and Masdar as we celebrate and accelerate the deployment of homegrown renewable energy at scale.

“East Anglia THREE will be the biggest and most powerful offshore windfarm in our portfolio. That means billions of pounds invested in UK and global supply chains; thousands of jobs supported during construction; more than a hundred long-term roles created in the East of England; and greater energy security, with more clean power coming on to the grid than ever before.

“This achievement is testament to successful collaboration with our strategic investment partner, Masdar, and the dedication and excellence of our own teams and supply chain partners. East Anglia THREE will play a crucial role in the UK’s clean energy future and it’s fantastic to see our vision come to life.”

Husain Al Meer, Director of Global Offshore Wind at Masdar said: “We are proud to work alongside ScottishPower and Iberdrola to bring this project to fruition and to be playing our part in securing the UK’s clean energy future, while helping to create jobs and drive sustainable growth.

“We see tremendous potential for offshore wind, not just in the UK but across the wider European market, where offshore wind can provide critical energy security, power economic progress and help nations achieve their clean energy objectives.”
