Nepal's rivers carry the snowmelt of the Himalayas through steep gorges that are, from an engineering standpoint, among the best hydropower sites on earth. The country's theoretical hydropower potential is estimated at around 83,000 MW. Its technically and economically feasible potential, accounting for topography, hydrology, and accessibility, is approximately 42,000 MW. As of 2025, installed capacity across all projects stands at roughly 3,200 MW.
That 3,200 MW is not evenly distributed in time or space. The majority of Nepal's projects are run-of-river schemes. They generate electricity when rivers flow and very little during the winter dry season. Peak generation in the monsoon months from June to September far exceeds domestic demand. In winter, Nepal imports power from India to meet the shortfall. The country is simultaneously a power exporter and a power importer, depending on the month.
The seasonal mismatch
Nepal's energy calendar has two seasons: monsoon surplus and winter deficit. In July and August, rivers swell and run-of-river plants generate at or near capacity. The national grid produces more electricity than domestic consumption requires, and the surplus is sold to India at prices that reflect India's own wet-season abundance, which is to say, low prices. In December and January, river flows drop by 60 to 80%, generation collapses, and Nepal imports expensive peaking power from India at rates far exceeding what it earned on its monsoon exports.
This seasonal asymmetry is the fundamental commercial problem of Nepal's hydropower sector. Storage projects, dams that hold monsoon water for dry-season release, would resolve it. But storage projects are larger, more complex, more expensive, and more politically contentious than run-of-river alternatives. The private sector has overwhelmingly favoured run-of-river. The state has been unable to develop storage at scale.
The India export question
Electricity export to India has been framed, by successive governments, as the transformational opportunity that will fund Nepal's development the way oil funded the Gulf states. The analogy is seductive and, in important respects, misleading. Nepal's hydropower is renewable, clean, and increasingly valuable in a decarbonising world. All of this is true. But the price Nepal receives for its power exports, and the terms on which India buys, reflect a profound imbalance in negotiating leverage.
Nepal exports power to India under the Power Trade Agreement of 2014, at rates set through bilateral negotiation. Indian buyers, primarily state utilities, purchase at prices that have ranged between Rs4 and Rs8 per unit, depending on season and project type. Wet-season power, when India has its own surpluses, is purchased at the lower end of that range. There is no liquid regional market in which Nepal could sell to multiple buyers and discover a competitive price.
The private sector pipeline
Nepal's private hydropower sector has been the engine of capacity growth since the early 2000s, when liberalisation opened the sector to independent power producers. Hundreds of companies, ranging from serious infrastructure developers to politically connected shells, hold licences for projects at various stages of development. The pipeline looks impressive on paper, with over 8,000 MW of projects under construction or with licences issued. The delivery rate tells a more sobering story.
Project delays are endemic. Transmission evacuation infrastructure, the high-voltage lines that carry power from remote generation sites to the grid, routinely lags behind project completion. Several recently commissioned plants have operated at reduced output for extended periods because the transmission line was not ready. The Nepal Electricity Authority, which manages the grid, is chronically under-resourced and faces political pressure that compromises its commercial mandate.
The path to the promise
Realising even a fraction of Nepal's hydropower potential requires resolving three linked problems simultaneously. Financing large storage projects that the private sector will not build alone. Constructing transmission infrastructure faster than projects come online. And negotiating power purchase agreements with India and Bangladesh that reflect the actual value of dispatchable storage power rather than marginal monsoon generation.
None of these is impossible. Nepal has built serious generation capacity in the past decade. The Upper Tamakoshi project, 456 MW completed in 2021 after years of challenges, demonstrated that large-scale construction is achievable. The question is whether the political will and institutional capacity exist to do it at the scale and pace that the resource opportunity and the climate moment demand. The answer, so far, has been: not quite.
