Britain's Royal Windsor Castle to get hydro-electric power plant

Windsor Castle, one of Queen Elizabeth II of the United Kingdom's official residences, is to get a hydro-electric power scheme.

The £1 million project will consist of a series of under-water turbines to be installed at Romney Weir in the nearby River Thames. The system will generate 200kW, enough to meet approximately one third of the castle's electricity needs.

The electricity from the four turbines will not be sold into the local electricity grid, but will instead be directly connected to Windsor Castle's electrical system. It will save 600 tonnes of carbon dioxide from being released into the atmosphere every year.

The scheme was announced after it gained planning permission from the local council, the plans having been submitted in February of last year. A feasability study will now be conducted, with construction scheduled to start next year.

The Windsor Castle is not the only environmentally-friendly Royal scheme. A borehole beneath Buckingham Palace provides cold water for air-conditioning and the Duke of Edinburgh's taxi runs on liquid petroleum gas.
