Thames Estuary wind farm 'powering up'

It is thought to be the largest working wind farm in the world and it is in the Thames Estuary.

BBC London's Tom Edwards has visited the London Array wind farm a few months before it becomes fully operational.

Steve Reynolds, the off-shore site manager, and London Array's Joanne Haddon show how the site will help power the capital.
