The Calder Water Wind Farm is situated within a plantation forest on the western boundary of South Lanarkshire, immediately to the south of West Browncastle Wind Farm and 2½ miles (4 km) northwest of Drumclog. It takes its name from the Calder Water, a river which flows along its northern boundary. The farm comprises thirteen Siemens SWT-3.0-101 direct-drive turbines, each producing 3 megawatts (MW) of power, giving a total generation capacity of 39 MW. The site was developed and is operated by Community Wind Power and was commissioned in October 2013.
The towers are 96m (315 feet) in height and the blade diameter is 101m (331 feet), giving a height to blade tip of 147m (482 feet). Each tower is secured on a reinforced concrete foundation. The optimal wind speed is 13 metres/second (30 mph) but generation begins at 4 m/s (9 mph) and the turbines stop at 25 m/s (56 mph) for reasons of safety.
The immense Whitelee Wind Farm lies immediately to the northwest.
