Chenkulam Dam is a gravity dam located on the Muthirapuzha riverinVellathooval panchayatofIdukki district in the Indian state of Kerala.[1] It spans 144.50 metres (474.1 ft) long and stands 26.82 metres (88.0 ft).[1] It hosts a 48 MW power plant.[2]
The project was commissioned in 1954 with a capacity of 48 MW (4 x 12 MW). The dam was constructed in 1957 as part of the Chenkulam Hydroelectric Project.[3][4] In 2002, the project was upgraded from 48 MW to 51.2 MW.[5]
The Chenkulam Project was intended to use the tailrace water of the Pallivasal project. The dam is constructed of masonry. The power house is situated at Vellathooval in Devikulam taluk.[2] The water collected is conveyed through a penstock pipe to the Chenkulam powerhouse in Vellathooval, which generates 51.2 MW of electricity using four 12.8 MW turbines.[2] Annual production is 182 MU.[5] Taluks receiving release flow are Udumbanchola, Devikulam, Idukki, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungalloor and Paravur.[1]
Chenkulam reservoir formed behind the dam. The catchment area of the reservoir is approximately 5.18 km2 (2.00 sq mi).[2] The tailrace discharge joins Mudirapuzha river and flows downstream to Kallarkutty reservoir.
