Westmill is the first wind farm in the South East of England and the first 100% community owned scheme in the UK from commissioning. The five turbines produce pollution-free electricity for over 2,500 average homes.
The wind farm consists of five towers 49 metres high, topped by a nacelle containing the generator, gearbox and other operating equipment. Each generator is driven by a three-bladed propeller, with each blade measuring 31 metres.
The electricity generated is conveyed by underground cable to a sub-station, where it is be metered and fed into the local grid. Crop farming continues as before with planting taking place right up to the base of the towers.
The blades start turning when the wind speed at hub-height reaches 3 to 5 m/s. At very high wind speeds the blades stop rotating to prevent damage.
