NHPC Ltd. has completed the renovation and modernization of its 180-MW Baira Siul Power Station and commenced commercial operation.
Baira Siul is NHPC’s first power station and began commercial operation in April 1982. The run-of-river facility is located on the Baira, Siul and Bhaledh rivers in Himachal Pradesh state, India.
The hydro plant had completed its useful life of 35 years, and the modernization was intended to extend the life of the station, which contains three Francis turbine-generator units.
The renovation and modernization was completed in stages. Unit 2 was put back into operation in December 2019 and Unit 1 in November 2020. Unit 3 commenced operation on Aug. 31, 2021, making the facility fully operational once again.
NHPC said the life of the Baira Siul Power Station has now been extended by another 25 years.
In September 2016, NHPC signed a US$19.9 million contract with Bharat Heavy Electricals Ltd. to complete the rehabilitation and upgrade. The scope of the agreement covers the electromechanical works package that includes: dismantling the existing system and supplying, constructing and commissioning new turbines.
NHPC is a Category-A Miniratna Company under Ministry of Power, Govt. of India in the field of hydropower. NHPC has 24 operational power stations with a total installed capacity of 7,071 MW.
