The Carno Wind Farm project was submitted for planning permission in October 1993 following a full Environmental Impact Assessment and received unanimous approval in April 1994. It was completed in October 1996 and consists of 56 wind turbines each of 600 kilowatts (kW) maximum output. The combined maximum power of 33.6 megawatts (MW) made Carno Wind Farm the largest in Europe at the time of its construction. It was developed and is operated by npower renewables.
The wind farm covers an area over 600 hectares (ha) of which only 6 ha (1%) are used by the turbines and access tracks. It is situated on a plateau which is 400 metres above sea level and includes areas of semi-natural grassland, changing to blanket bog and valley mire in the wetter areas. To the south west there is the extensive commercial coniferous forest of Dal Gau.
