Montage of what the turbine could look like over Dagenham's Ford plant
Plans for two massive wind turbines at Ford's Dagenham plant have been approved by London's mayor.
The 85 metre towers with 35m blades which will make up London's first major 'wind park' have also been approved by Havering and Barking and Dagenham councils.
They will provide 100% of the electricity requirements of the new assembly hall being built to produce diesel engines at the plant.
Each turbine generates about enough electricity to power 1,200 homes and along with a similar turbine in Norfolk, are among the tallest in the UK.
Plans for a third 65m tower with a viewing platform which could provide power for local homes and businesses, also won approval.
The councils will now issue notices to finalise the procedure and it is hoped construction will be completed by the end of the year.
London mayor Ken Livingstone said: "The scheme will make an important contribution towards making London a more sustainable world city.
"I hope it will encourage other large organisations to consider
developing similar schemes on their premises."
Ecotricity's founder Dale Vince added: "We are pleased to have the mayor's support for this city wind park which we hope will be the first of many.
"In the long run this is going to make a real difference to the way manufacturers approach their energy demands.
"The recent power cuts in the United States have highlighted the need for diverse power supplies."
