About

Devighat Hydropower Station is the cascade hydropower station of Trishuli power station. It is located at Devighat, Nuwakot with installed capacity of 14.1 MW and annual design generation of 144 GWh. It was commissioned in 1984 AD and developed in assistance from Government of India and Government of Nepal with the total cost of NRs. 750 Million including transmission line. The rehabilitation of all the three units at a cost of INR 338.15 million was successfully completed by the contractor BHEL and handed over to NEA on July 13th, 2011. The capacity of the units is improved and presently, all the three units are in normal operation. The operational capacity is based on the availability of the flow released from the upstream Trishuli Hydropower Station. After the successful completion of RMU project in Devighat in fiscal year 2010/11, the generation has been satisfactory and is limited only by the obstacles in generation faced by upstream plant of Trishuli in one of its unit. The cumulative generation of Devighat HPS has now reached 2309.38 GWh till 2011/12 from its first run. This station generated 74.13 GWh in FY 2010/11 and 105.09 GWh in FY 2011/12 with an increase of 41.76%. The generation from this station contributed 1.92 % and 2.51% of the total energy to the INPS in FY 2010/11 and 2011/12 respectively.
