BHEL commissions third renovated Hydro unit at 3×60 Baira Siul HEP

The R&M of the project will result in restoration of output capacity and improvement in efficiency and life extension of equipment.

BHEL has successfully completed Renovation & Modernisation (R&M) and commissioned the third and final unit of the 3×60 MW Baira Siul Hydro Power Station located in Chamba district of Himachal Pradesh. The first and second units of the station have already been renovated and commissioned in Dec., 2019 and Oct., 2020 respectively. BHEL had won the order for R&M of the three units of Baira Siul Hydro Power Station amidst stiff competitive bidding.

Set up in 1981, Baira Siul is the first hydro station of NHPC Limited and also the first to be taken up for comprehensive Renovation & Modernisation (R&M). The R&M of the project will result in restoration of output capacity and improvement in efficiency, besides leading to better plant availability and life extension of equipment. Significantly, the capacity of each unit has been maintained at the rated output of 60 MW, even at the reduced head of 238.1 metres, as compared to the originally designed rated head of 260 metres.
