Coal Clough Wind Farm is one of the oldest onshore wind farms in England. The wind farm, which was built for Scottish Power, currently produces electricity from 24 Vestas WD34 wind turbines. It has a total nameplate capacity of 9.6 MW of electricity, enough to serve the average needs of 5,500 homes. It is situated near Burnley, Lancashire in the parish of Cliviger, near Coal Clough Farm, on the edge of Stiperden Moor in the South Pennines. For just a few weeks it was the largest wind farm in the UK, until the much larger Penrhyddlan and Llidiartywaun wind farms (now called Llandinam) in Powys, Wales overtook it. It narrowly remained the largest in England until Coldham opened in Cambridgeshire in November 2005, the record is currently held by Scout Moor Wind Farm just 7 miles (11 km) to the south west. In 2009 Scottish Power announced plans to replace the existing turbines with eight 2 MW units with an estimated maximum height 110 metres (361 ft).
