Sengulam Dam is a gravity dam located on the Muthirapuzha river in Vellathooval panchayat of Idukki district in the Indian state of Kerala. It spans 144.50 metres (474.1 ft) long and stands 26.82 metres (88.0 ft). It hosts a 48 MW power plant.

History

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 Sengulam Hydroelectric Project. In 2002, the project was upgraded from 48 MW to 51.2 MW.

Project

The Sengulam 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. The water collected is conveyed through a penstock pipe to the Sengulam powerhouse in Vellathooval, which generates 51.2 MW of electricity using four 12.8 MW turbines. Annual production is 182 MU. Taluks receiving release flow are Udumbanchola, Devikulam, Idukki, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungalloor and Paravur.

Reservoirs

Reservoir

Sengulam reservoir formed behind the dam. The catchment area of the reservoir is approximately 5.18 km2 (2.00 sq mi). The tailrace discharge joins Mudirapuzha river and flows downstream to Kallarkutty reservoir.
