Hydro Power

Beginning from a single hydropower project company, SJVN today has a footprint in a Hydroelectric Projects in Himachal Pradesh, Uttrakhand and in the neighboring countries of Nepal and Bhutan.

SJVN is successfully operating the country’s largest 1500 MW Nathpa Jhakri Hydropower Station and is setting new benchmarks in generation and maintenance year after year, after having tackled the silt erosion problems in under-water turbine parts.

Tandi and Rashil HEPs located on river Chenab in Himachal Pradesh with proposed capacity of 104 MW and 130 MW respectively were allotted by GoHP on 05.01.2021.

After preliminary investigations, a composite proposal of 268 MW  was submitted to DoE, GoHP for approval on 06.05.2022. Approval by GoHP for combined scheme was granted on 02.07.2022. The project has been registered by CEA for further investigation.

Luhri Hydro Electric Project is located on river Satluj spread over Shimla, Kullu and Mandi districts of Himachal Pradesh. Initially LHEP was contemplated as single stage project and Implementation Agreement with Govt. of Himachal Pradesh was signed on 27.10.2008. Govt. of H.P. in March, 2015 advised SJVN to explore the possibility of executing the LHEP as multi-stage project instead of single stage on account of social and environmental concerns. Accordingly three stages (i.e. Luhri HEP Stage- 1 - 210 MW, Luhri HEP Stage-2 – 172 MW and Sunni Dam HEP- 382 MW) were envisaged to harness the hydel potential of Satluj river between Rampur and Kol Dam Hydro Electric Projects. Govt. of H.P. reallocated all three projects on "Stand Alone Basis" to SJVN on 29.08.2017. MoU signed with GoHP on 25.09.2019.

Luhri HEP Stage-1 is a Run of the River (RoR) scheme with installed capacity of 210 MW, located on river Satluj, near Nirath village spread over Shimla and Kullu Districts of Himachal Pradesh. The project holds potential of generating 758 MU of electric energy in a 90% dependable year. Sanction order for Investment approval issued by MoP, GoI on 20.11.2020.
