History

edit

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]

Project

edit

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]

Reservoirs

edit

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.
