The proposed wind turbine, known locally as ‘the Angel of Leyton’, will stand 130m tall at Eton Manor in the north of the Park. It will produce the energy equivalent to supplying 1,000 homes over an average year.

Detailed planning permission was granted in September 2007 and construction is due to start later this year. It is expected to be completed by 2010, providing new renewable energy nearly two years before the Games.

After the Games the turbine will provide power to the local housing and amenities that will be developed in the area.

ODA director of Infrastructure Simon Wright said: "Sustainability runs through all we are doing and the use of renewable energy is key part of our plans to provide a whole new backbone of services, fuelling not just six weeks of world-class sporting action, but also the lasting regeneration of the area for many years to come.

"As one of the first large-scale wind turbines so close to central London, this contract is chance for companies to deliver a ‘green beacon’ for the capital and a striking symbol of the sustainability principles behind the Games."
