The Nepal Electricity Authority (NEA) has prioritized the construction of pumped storage hydropower projects to manage daily electricity demand fluctuations and enhance the country’s energy security. The NEA’s Project Development Department has identified 156 potential pumped storage projects nationwide.
Of these, 33 projects with a combined capacity of 42,000 MW have been shortlisted and categorized. A feasibility study is underway for a 332 MW pumped storage project in Syarphu Lake, Rukum (West), after obtaining a survey permit. Additionally, the 670 MW Dudhkoshi Reservoir Hydropower Project is studying a 200 MW pumped storage component.
A feasibility study is also being conducted for the 1,596 MW Hulingtar-Dukim Pumped Storage Project in Dhading’s Benighat Rorang and Chitwan’s Ichhakamana rural municipalities. Located near Kathmandu, this project benefits from access to roads, transmission lines, and other necessary infrastructure. The NEA’s Project Development Department is currently conducting a Detailed Engineering Study (DEX) for the project.
The project involves constructing two reservoirs by building 45-meter and 103-meter-high dams on the Hugdi (upper) and Mowa (lower) rivers, respectively. The power plant will be situated on the Mowa River. Electricity will be generated using water stored in the Hugdi reservoir, and after generation, the water will be pumped back from the Mowa reservoir to Hugdi. The project is designed to operate at full capacity for six hours during peak demand periods.
Pumped storage projects store water in an upstream reservoir during off-peak hours when energy prices are low. This stored water is later used to generate electricity during peak hours when demand and prices are higher. These projects play a crucial role in power system stability, peak demand management, and surplus energy utilization. They also enable Nepal to generate and consume electricity efficiently while exporting surplus energy to India at premium rates during peak periods.
On Saturday, NEA Executive Director Kulman Ghising, Project Development Director Nasibman Pradhan, and other officials inspected the Hulingtar-Dukim project site. Ghising highlighted the project’s advantages over others due to its strategic location, favorable environmental and social conditions, accessibility, infrastructure availability, and proximity to transmission lines and power demand centers.
Ghising stated that the project would initially be developed with a capacity of 510 MW in the first phase, eventually expanding to full capacity. “The process of obtaining a survey permit will be prioritized to accelerate construction,” he said. The project is expected to generate approximately 3.36bn units of electricity annually, with an estimated cost of $587,000 per megawatt.
