UK Installs Record 115-Meter Wind Turbine Blades at Sea

A wind turbine blade longer than a Premier League football pitch just started spinning off the coast of Suffolk, marking a breakthrough moment for British renewable energy.

ScottishPower Renewables and Masdar installed the first turbine at the East Anglia THREE offshore windfarm, featuring blades stretching 115 meters long. That's seven meters longer than any previous UK offshore wind blade, and all 285 of them are being manufactured domestically at Siemens Gamesa's factory in Hull.

The numbers behind these giants are staggering. Standing 262 meters tall (higher than the Shard's observation deck), each turbine generates 14 megawatts of power. A single rotation produces enough electricity to power a UK home for more than four days, charge 1,700 mobile phones, or brew nearly 1,000 cups of tea.

The £4 billion project involves installing 95 of these record-breaking turbines off the Suffolk coast. When fully operational, East Anglia THREE will generate 1.4 gigawatts of clean electricity, enough to power more than 1.3 million British homes.

Charlie Jordan, CEO of ScottishPower Renewables, called it "a defining moment" for homegrown renewable energy. The project represents billions invested in UK supply chains, thousands of construction jobs, and over 100 permanent positions created in the East of England.

The Hull factory where these blades are manufactured now employs more than 1,400 people. The facility is also training the next generation of workers through an established apprenticeship program, ensuring the UK maintains its expertise in offshore wind technology.

The Ripple Effect

This isn't just about one impressive windfarm. East Anglia THREE demonstrates how the UK is scaling up domestic clean energy production while creating high-quality manufacturing jobs. The project strengthens energy security by producing more power locally, reducing dependence on imported energy.

The installation uses cutting-edge vessels including Cadeler's new P-class Wind Pace, making its first deployment in European waters. These specialized ships can install the massive turbines efficiently, keeping the project on track for completion.

When East Anglia THREE comes fully online, it will rank among the world's largest offshore windfarms, cementing the UK's position as a global leader in offshore wind technology. The success shows how ambitious clean energy projects can deliver both environmental progress and economic growth simultaneously.
