The largest wind turbines built in the world to date will help Britain to power 230,000 homes, with just a single blade rotation generating sufficient electricity to produce 29 hours' worth of power for a home.

The vast turbines are housed at the Burbo Bank Extension Wind Farm, which is now officially operating with innovative and newly designed MHI Vestas turbines installed by Dong Energy. It will produce clean and green energy for 320,000 properties.

Located along the coast of Liverpool, the new development is the first of its kind that uses the MHI Vestas turbine model. Each one stands at a vast 195 metres in height, which is taller than the Gherkin in London. Each blade is 80 metres long.

Backers of the scheme say that the new development has played a crucial role in developing Britain's renewable energy supply chain. The blades are manufactured in the Isle of Wight, the linking fixtures are manufactured in Teesside and overall assembly is carried out in Belfast.

The new development is so powerful that just a single turbine generates more power than the entire Vindeby offshore wind farm, which was built by Dong Energy in Denmark 25 years ago.

Burbo Bank is now being used as a showcase for the offshore wind energy industry and its rapid growth and evolution. Dong Energy said that this innovation was helping to drive down the cost of offshore wind energy and advancing the wind power sector on a global scale.

The Mayor of the Liverpool City Region, Steve Rotherham, said that wind power was making a vital contribution to Britain's growing renewable energy supply chain and that the Burbo Bank development was helping Merseyside to consolidate its position as a leader in low-carbon technologies.
