SHANAN POWER HOUSE, PSEB, JOGINDER NAGAR (110 MW)

110 MW Shanan Project is the most picturesque project in the beautiful surroundings of Himalayan ranges. It is situated in the North Indian State, Himachal Pradesh at an approximately longitude of 76 degree – 51’ East and latitude of 32 degree – 2’ North. It takes advantage of two small rivulets at an altitude of about 6000 ft., in Brot valley. The idea of harnessing a power potential of 4X12 MW (48 MW) initially was envisaged by Col. Battye, the then Chief Engineer of Govt. of Punjab in 1922. This 48 MW Stage Ist Project was constructed at the initial cost of Rs. 2,53,43,709/- and commissioned in 1932 and was officially opened by His Excellency, The Viceroy of India at Shalimar Receiving Station, Lahore on 10th March, 1933.

Shanan Power House, 1st Stage of 4X12 = 48 MW was renovated to 4X15 = 60 MW in 1982. No major work in the form of additions and alterations in Head works, water conductor system, Power House building was involved.

The Shanan renovation project was finally commissioned in December, 1982.

SHANAN EXTENSION PROJECT (50 MW).

As originally conceived by Col. Battye, the extension of the 1st Stage of Uhl river Project was proposed by constructing an additional unit of 50 MW. This extension work mainly consisted of a new extended reservoir at Brot, laying of new penstock for 50 MW and construction of new power house building. Finally this project with unit of 50 MW was commissioned in March, 1982.
