Chenderoh Power Station or Chenderoh Dam was the first major hydroelectric dam and power station in Malaysia. It was preceded by two earlier booiis on Malaya's rivers; the Ulu Gombak station of 800kw in Selangor (1905) that was used to provide Kuala Lumpur's first electricity, and the Sungei Besi Tin Mines Ltd scheme at Ulu Langat that was purchased by FMS Electrical Department in 1929. The dam is located at Chenderoh Lake, Kuala Kangsar District, Perak. It was constructed by Perak River Hydro-Electric Power Company Ltd and completed between 1929 and 1930. The scheme was designed by consulting engineers Rendel, Palmer & Tritton of London and Vattenbyggnadsbyran (VBB) of Stockholm, Sweden. The architect was Osvald Almqvist.
The Chenderoh plant was constructed in tandem with a steam power station at Malim Nawar, 65 km south of Chenderoh, that was commissioned in 1928. Between them the stations supplied power to Kinta Valley's tin mining industry and associated settlements.
The station is operated by Tenaga Nasional.
