Siemens Gamesa 377-Foot Blades For Offshore Wind Farm

ScottishPower Renewables (ScottishPower) and Masdar’s East Anglia THREE offshore wind farm has set a UK offshore wind record with the installation of its first turbine. The turbine is the first in the UK to feature 377-foot (115 m) blades, each one longer than an American football field or a Premier League football pitch.

All 285 of the record-breaking blades for the project’s 95 turbines are being manufactured in the UK at Siemens Gamesa’s factory in Hull. The 14MW Siemens Gamesa turbines stand 860 feet (262 m) tall and have a rotor diameter of 774 feet (236 m).

According to ScottishPower, a single revolution of a turbine will produce enough electricity to power a UK home for more than four days, charge around 1,700 mobile phones, or brew nearly 1000 cups of tea.

“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,” said Charlie Jordan, ScottishPower Renewables chief executive officer (CEO). “East Anglia THREE will be the biggest and most powerful offshore wind farm 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 a 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.”

Located off the Suffolk coast in the UK, East Anglia THREE will be one of the world’s largest offshore wind farms when it comes into operation, delivering clean electricity to power the equivalent of 1.3 million British homes.

“This is a milestone moment for the UK’s offshore wind sector, with the completion of the first turbine for East Anglia THREE representing a truly monumental achievement,” said Husain Al Meer, director of global offshore wind at Masdar. “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.”

The blades used on the East Anglia THREE turbines are 23 feet (7 m) longer than the previous record of 354 feet (108 m). Those 354-foot blades were also manufactured by Siemens Gamesa.

“These are the biggest blades ever built for a project in UK waters – a real landmark for offshore wind,” said Darren Davidson, UK Head of Siemens Energy and Siemens Gamesa. “We’re proud that these record-breaking blades have been manufactured at our factory in Hull, where we now employ more than 1,400 people, and where we’re also investing in the future by training our next generation of workers through a well-established and successful apprenticeship scheme.”

The turbine installation was completed using Cadeler’s O-class Wind Osprey jack-up vessel, which will be joined later this month by the next-generation P-class Wind Pace on its first deployment in European waters as the installation program continues.

“We are proud to support ScottishPower Renewables and Masdar on East Anglia THREE – our first project together and a strong starting point for future collaboration, said Mikkel Gleerup, CEO of Cadeler. “By deploying two of our vessels in parallel, we can maintain a consistent and efficient installation pace throughout the campaign. This also marks Wind Pace’s first project in European waters since her delivery last year. Built to install the next generation of turbines, she brings increased capacity and operational flexibility, enhancing installation efficiency and supporting a more streamlined program. Together, this strengthens our ability to deliver safely, reliably, and at scale.”
