Nepal Electricity Authority / Generation Directorate

Generation Directorate, headed by Deputy Managing Director is responsible for construction of new power projects together with operation and maintenance of NEA owned power stations. The main objective of this Directorate is construct new projects owned by NEA and smooth operation and maintenance of existing power plants with optimal use of resources. The Directorate is supported by four departments, namely Generation Development Department(GDD), Technical Support Department,(TSD) Large Generation Operation and Maintenance Department(LGO&MD), Medium Generation Operation and Maintenance Department(MGO&MD) each headed by Director. It is supported by three divisions/sections namely, Finance, Administration and Monitoring and IT. At present, this Directorate is taking care of construction of the following four hydropower projects.

    1. Kulekhani III Hydroelectric Project(14MW)
    2. Chameliya Hydroelectric Project (30MW)
    3. Rahughat Hydroelectric Project(40 MW)
    4. Upper Trishuli 3'A' Hydroelectric Project(60MW)


Chameliya Hydroelectric Project, Rahughat Hydroelectric Project and Upper Trishuli 3'A' Hydroelectric Project are headed by respective Project Directors and report to the Deputy Managing Director. Whereas, Kulekhani III Hydroelectric Project is headed by Project Manager and reports to the Director, GDD. The TSD provides technical support needed for the ongoing projects and existing power plants on coordination with respective Directors. LGO&MD is responsible for five (5) hydropower and one (1) thermal plant above 30MW installed capacity owned  by NEA. Similarly MGO&MD is responsible for twelve 12 hydropower and one (1) diesel plant which are below 30MW installed capacity owned by NEA. 


Generation Development Department

Generation Development Department has the main objective of performing regular monitoring, inspection and resource management of under-construction projects of Generation directorate. Presently, it is overseeing the construction of Kulekhani III hydropower project (14 MW), which is a cascade project of the only storage power plant in Nepal viz. the Kulekhani hydropower plant. To accomplish this objective, GDD has a mandate to prepare policies and programs, to ensure the timely completion of under-construction projects, and submit it to the Generation directorate. Also, it provides necessary instructions to the projects after performing regular monitoring and inspection; submits timely reports of projects’ budget and progress to the directorate; performs essential record maintenance of projects’ resources, lands and buildings; prepare trimester progress report of the projects and submit it to the Generation directorate.


The operation and maintenance of five (5) hydropower plants and one (1) Multifuel diesel power plant with capacity above 30 MW fall under the jurisdiction of this department. The total installed capacity of these plants is 414 MW. There were no significant forced outages in these hydropower plants in the reporting period. However, electricity generation from these hydropower plants reduced in comparison to last fiscal year due to decreased river discharge in Kaligandaki and Marsyangdi rivers throughout the dry season this year and Main Inlet Valve (MIV) modification work which was initiated from May 23, 2016 at Kaligandaki ‘A’ hydropower plant. The generation from cascade Kulekhani I and Kulekhani II plants are mainly intended for meeting peak load demand as per system requirement. The Multifuel power plant is not in operation since Ashad 2071 due to legal dispute with and distruption of supply of oil from Nepal Oil Corporation. Total Generation from the hydropower plants under this department in fiscal year 2072/73 is 1.73 TWh.

Medium Generation Operation and Maintenance Department

Medium Generation Operation and Maintenance Department (MGO&MD), headed by a Director, is responsible for the operation and maintenance of twelve (12) hydropower stations and one (1) diesel power plants with individual installed capacity below 30MW and owned by NEA with an objective to maximize energy generation by optimally utilizing generation resources while undertaking rehabilitation, periodic overhauling and maintenance of generating facilities. It has always strived to uphold economy, operational efficiency and an acceptable level of reliability in its drive for improvement. The installed capacity of 12 hydropower stations and 1 diesel power plant with installed capacity below 30 MW is 108.39MW. The hydropower generating stations under this department have produced 8.32% of excess energy compared to that of past year and have achieved about 93.59% of target generation this year. Though the adverse condition were present, Gandak power station has generated 150% of its set target. Upon the installation and commissioning of turbocharger in unit no. 7 at Hetauda diesel plant, 14.41 MW installed capacity is in standby condition. There are five major rehabilitation projects ongoing under this department which are Gandak and Devighat with Nepal government funding; Chatara with funding from Nepal government and NEA; Sundarijal and Tinau with loan assistance from the Asian Development Bank (ADB) under Energy Access and Efficiency Improvement Project (EAEIP). Major maintenance works have been carried out for Chatara, Trishuli, Sunkoshi & Panauti hydropower plants which is still ongoing.

Technical Support Department

Technical support department provides the much needed expert advice to the special problems of ongoing and operational projects of NEA. In the past FY 2072/73, the service provided by this department comprises of

a) Proposal for rehabilitation of Trishuli Devighat Project : The present annual generation of these projects are about 25% below the rated capacity. Despite undergoing extensive rehabilitation program in 1992/93, the capacity of desander is not sufficient enough to fully flush out the sediment at  the rated  discharge of 45.3 m3/s. This has led to filling of the balancing pond by silt and is rather acting as a reservoir of sand discharge during the dry season. The resulting erosion has rendered 4 out of 7 turbines of Trishuli to dilapidated condition.  This department has hence made a proposal to build another bay of desander in Trishuli project and remove the debris from the balancing reservoir without a long shutdown period. The objective of this rehabilitation is to increase the generation by about 65 GWh/year for these two projects and curtail the cost for turbine maintenance.

 b) Provide advisory service to the ongoing problems of Kali Gandaki A: Major issues with the headwork involve heavy erosion in the first half portion of desander and erosion of the banks. A task for comprising of TSD has been formed to review and recommend the measures required to mitigate the problems/issues. TSD has actively participated in the assigned task and working out with other department to remedy the problems at the earliest

c) Framework for operation and maintenance of NEA hydropower projects: TSD has submitted draft report for enhancing the performance of o/m of NEA hydropower projects. There is a critical need for monitoring of operational parameters like sediment inflow, slope stabilization, need assessment of equipment procurement and suitable manpower at site that have a direct impact on generation.
