energy.wikisort.org - Power_plantThe Kotmale Dam is a large hydroelectric and irrigation dam in Kotmale, Sri Lanka. The dam generates power from three 67 MW turbines, totalling the installed capacity to 201 MW, making it the second largest hydroelectric power station in Sri Lanka. Construction on the dam began in August 1979 and was ceremonially completed in February 1985.[1] The dam forms the Kotmale Reservoir, which was renamed to Gamini Dissanayake Reservoir on 11 April 2003 following a request by Prime Minister Ranil Wickramasinghe.[2][3]
