Carno is a wind farm of 68 turbines which started operation in October 1996. It covers an area of over 600 hectares on Trannon Moor, a plateau to the west of the village of Carno in Powys, Mid Wales, 400 metres (1,300 ft) above sea level.
Carno currently has the largest production capacity in Wales.
Originally consisting of 56 wind turbines each of 600 kilowatts (kW) maximum output, the combined maximum power of 33.6 megawatts (MW) made Carno the largest Wind Farm in Europe at the time of its construction. The total project cost was approximately £26 million.Number of turbines: 56 (extended to 68 with Carno 2 in 2008)
