THDC India Ltd. has named Bharat Heavy Electricals Ltd. (BHEL) to supply electro-mechanical equipment for the 444-MW Vishnugad Pipalkoti hydroelectric project on India’s Alaknanda River.
The 4.22 billion rupee (US$68.9 million) contract calls for BHEL to provide engineering, procurement, and construction of electro-mechanical works including four vertical Francis turbine-generators of 111 MW each; single-phase, 40-MVa, 420-kV transformers; 400-kV gas-insulated switchgear; computerized control and monitoring system; spherical and butterfly valves; and XLPE cables. The 48-month contract also is to include assistance in operation for six months.
The India equipment supplier said hydro generating sets are to be supplied by BHEL’s Bhopal unit, while transformers are to be supplied by its Jhansi unit and the control and monitoring system will be supplied by the BHEL Electronics Division in Bangalore. Installation and commissioning will be performed by BHEL’s Power Sector — Northern Region.
THDC pre-qualified firms for the electro-mechanical equipment in 2012. India’s Hindustan Construction Co. won a US$260 million engineering, procurement and construction contract in January for civil works including a 65-meter-tall concrete gravity dam, surge shaft, pressure shaft, underground powerhouse, surge tank, headrace and tailrace.
THDC received a US$648 million loan from the World Bank in 2011 to help achieve financial closure of Vishnugad Pipalkoti, a run-of-river plant to be located in Chamoli District of Uttarakhand State.
BHEL also received an order in March for another hydropower project being built in Uttarakhand State, 120-MW Vyasi on the Yamuna River. Under a contract from utility Uttarakhand Jal Vidyut Nigam Ltd., BHEL is to perform detailed design and engineering, manufacture, installation, testing, and commissioning of electro-mechanical equipment and systems for Vyasi, including two 60-MW generating units.
