The first phase of the world's largest offshore windfarm is up and running. The final turbine at the London Array in the Thames Estuary has now been commissioned which means that all of them are exporting power to the national grid.

With all turbines now exporting power to the national grid, London Array is expected to produce enough green electricity to power nearly half a million homes a year.
