Construction of the dam formed a large lake, Temenggor Lake.The power station is a hydroelectric power station, using 4 Hitachi turbines of 87 MW installed capacity. The station is operated by Tenaga Nasional. Since 1987 Temenggor has been unmanned and is remotely operated via a SCADA system at the Bersia Group Control Centre. In the late 1990s, facilities were added to enable Automatic Generation Control by TNB's National Load Despatch Centre in Kuala Lumpur.Temenggor Dam is now the third largest dam in Malaysia. It was once the largest dam and largest hydroelectric generation facility upon completion in 1979, before being overtaken by the Kenyir Dam in 1985. It holds a special place in the history of Malaysia for its military role in flooding the Upper Perak River and cutting off the communist terrorists' infiltration route from the Betong salient in Thailand.
