Jal Power Corp. Ltd. has awarded three civil works packages to Coastal Project Private Ltd. for construction of a powerhouse and related works of the 120-MW Rangit Stage 4 hydroelectric project on India’s Rangit River.

Jal Power said contracts include: a headrace tunnel and adit for 1.28 billion rupees (US$29.7 million); a dam, intake, and desilting chamber for 1.25 billion rupees (US$29 million); and powerhouse civil works including surge shaft, pressure shaft, and tailrace channel for 777.9 million rupees (US$18 million).

Jal Power is developing the project on a build-own-operate-transfer basis to be completed in 2012-2013. (HNN 3/10/08) Rangit 4 features a 44-meter-tall concrete gravity dam, three 130-meter-long underground desilting chambers, and three intakes.
