When fully operational, it will be the world's largest offshore wind farm - and, as these pictures show, work on the project in the Thames Estuary is moving along at quite a pace.

The wind farm, which is being built in the shallow waters 12 miles off the coasts of Kent and Essex, which, when complete will feature 217 turbines that will be able to supply enough electricity to power a quarter of London's homes.

The 1.7 billion wind farm, known as the London Array, is owned by the utility companies E.ON, Dong Energy and Masdar and is expected to start sending energy to the National Grid next spring.

The first phase of the project will generate 630 megawatts of power - equivalent to a small gas or coal fired power station and enough to supply 470,000 homes.

The second phase will bring the total to 217 turbines, each towering 147 metres above the estuary, giving 1000 mw of power, enough for 750,000 homes.

Work on the project began in January.

It was originally given the go-ahead in May 2009.

At present, the world's largest offshore wind farm is the 102-turbine Walney project, located off the coast of Cumbria.

The Walney project is capable of providing sufficient electricity for about 320,000 homes.

Only when the wind is blowing at the right speed. The future - probably the area will be marked for shipping as "Hazardous wrecks".

Great News! floating deep sea wind turbines next please. out of sight therefore no Nimbys complaining or bird strikes. mean wind speed is higher further offshore, so they will produce more energy. new advances in turbine design means they will go from strength to strength. not long now and we can be rid of nasty coal and oil.
