National Hydroelectric Power Corp. (NHPC) has awarded a 4.02 billion rupee (US$87 million) contract to Bharat Heavy Electricals Ltd. (BHEL) to supply turbine-generators and other electro-mechanical equipment for the 520-MW Parbati 3 project on the Sainj River in Himachal Pradesh State.

NHPC announced February 1 the signing of the agreement, which includes design, manufacture, supply, installation, testing, and commissioning of four 130-MW vertical shaft Francis turbines; four main inlet spherical valves; four 159-megavolt-ampere, 13.8-kilovolt, three-phase, 50 HZ synchronous generators; step-up transformers; computer-based control, protection, and monitoring equipment; and auxiliaries.

In 2006, NHPC awarded contracts for civil construction of Parbati 3.

A 3.24 billion rupee (US$70.97 million) contract went to a joint venture of Jager Bau GmbH and Gammon India Ltd. to construct part of the headrace tunnel, the surge shaft, pressure shaft, powerhouse, and tailrace tunnel.
