Kathmandu, Nepal - Nepal’s hydropower sector is entering a decisive phase. With electricity generation expanding and cross-border power trade gaining momentum, the country now faces a strategic choice: remain primarily a seasonal exporter of surplus electricity or build the transmission networks, domestic markets and regional agreements needed to turn hydropower into a long-term foundation for energy sovereignty and economic transformation.
Nepal is estimated to possess a theoretical hydropower potential of around 83,000 megawatts, of which approximately 43,000 MW is considered technically and economically feasible. Yet installed generation capacity remains only around 4,200 MW, while domestic electricity demand is roughly 2,000-2,200 MW. This gap highlights both the scale of Nepal’s untapped resource and the infrastructure challenge standing between potential and prosperity.
The country has already demonstrated that electricity can become an important export commodity. In fiscal year 2025/26, Nepal sold electricity worth approximately Rs29.32 billion to India and Bangladesh, while also importing electricity during the dry season. Nepal recorded a substantial electricity-trade surplus and has increasingly emerged as a net power exporter.
Transmission is becoming the critical link
The central challenge is no longer simply generating more electricity. Nepal must also ensure that power can reach domestic consumers and regional markets when and where it is needed.
In July 2026, Nepal and India agreed to expand electricity transfer capacity through key cross-border transmission corridors. The two countries agreed to raise the combined export capacity through the Dhalkebar-Muzaffarpur and Dhalkebar-Sitamarhi 400 kV lines to 1,650 MW, while the new Butwal-Gorakhpur interconnection is expected to initially facilitate up to 200 MW of exports.
These developments are significant because Nepal’s hydropower generation is highly seasonal. River flows increase during the monsoon, creating electricity surpluses, while production falls during the dry winter months. Without adequate transmission infrastructure and reliable markets, surplus electricity can lose economic value.
Nepal therefore needs to accelerate both domestic grid expansion and cross-border transmission projects. The proposed infrastructure should not merely support exports; it should also strengthen the reliability and quality of electricity supplied to industries, farms, businesses and households inside the country.
India remains crucial-but diversification matters
India is currently Nepal’s principal electricity market, making bilateral cooperation indispensable. But dependence on a single external market also creates strategic vulnerability.
Nepal has already begun diversifying its regional electricity trade through Bangladesh. Under a tripartite agreement involving the Nepal Electricity Authority, Bangladesh Power Development Board and India’s NTPC Vidyut Vyapar Nigam, Nepal exports 40 MW of electricity to Bangladesh during the monsoon season, using India’s transmission network.
Nepal has sought to increase this to 60 MW, but an additional 20 MW has faced delays because of transmission-capacity constraints and the need for further approvals.
The experience illustrates an important lesson: generation capacity alone cannot create energy security or a regional electricity market. Transmission corridors, regulatory approvals and long-term power-purchase arrangements are equally important.
From seasonal exports to long-term energy diplomacy
Nepal should therefore pursue predictable, long-term electricity agreements with both India and Bangladesh rather than relying excessively on short-term opportunities in the monsoon market.
Long-term power-purchase agreements of 15-25 years could provide greater certainty for investors and hydropower developers while allowing neighbouring countries to incorporate Nepali electricity into their long-term energy planning.
At the same time, Nepal needs a more strategic approach to project approvals and export permissions. Recent developments demonstrate that regional electricity trade depends on interconnected infrastructure and the regulatory decisions of multiple countries.
The goal should be a stable South Asian electricity market in which Nepal’s clean hydropower can complement the energy needs of its neighbours while generating reliable foreign-exchange earnings for Nepal.
Energy sovereignty begins at home
Regional exports, however, should not come at the expense of domestic economic transformation.
Nepal still imports large quantities of fossil fuels, including liquefied petroleum gas (LPG), placing pressure on the national import bill. Expanding the use of domestically generated electricity for cooking, transport, irrigation and industrial production could reduce fossil-fuel dependence while creating new domestic demand for hydropower.
Electric induction cooking, electric water pumps, electric mobility, industrial electrification and cold-storage systems are among the areas where Nepal could substantially increase electricity consumption.
The agricultural sector offers particularly significant opportunities. Replacing diesel-powered irrigation pumps with electric systems could lower operating costs for farmers while creating a new domestic market for electricity. Expanded cold-storage and refrigeration infrastructure could also help reduce post-harvest losses and strengthen agricultural value chains.
Surplus electricity can power a new economy
Nepal should also look beyond conventional electricity consumption.
Periods of electricity surplus could support pumped-storage hydropower, grid-scale battery storage, green hydrogen production, data centres and other electricity-intensive industries, provided that these investments are economically and environmentally viable.
The objective should be to transform electricity from a commodity that Nepal simply exports into an economic input that supports manufacturing, agriculture, digital infrastructure and green industries.
That transition would create greater domestic value from Nepal’s hydropower resources and reduce dependence on imported petroleum products.
The path to energy sovereignty
Nepal’s hydropower opportunity is enormous, but potential alone does not guarantee energy security or prosperity.
The country now needs a coordinated strategy built around four priorities: rapid transmission expansion, diversified regional electricity markets, increased domestic electrification and stronger long-term energy diplomacy.
Recent progress in electricity exports and cross-border transmission shows that Nepal has already moved beyond the era in which it was viewed primarily as an electricity importer. The next challenge is to ensure that this progress becomes structurally sustainable.
For Nepal, energy sovereignty should not mean isolation from regional electricity markets. Rather, it should mean having sufficient domestic generation, transmission infrastructure, storage, diversified markets and domestic consumption capacity to make strategic choices from a position of strength.
If Nepal can achieve that balance, its rivers could become more than a source of seasonal electricity exports. They could become a foundation for cleaner industries, stronger rural economies, reduced fossil-fuel imports and deeper regional cooperation.
The future of Nepal’s hydropower sector will therefore depend not only on how much electricity the country can generate, but on how intelligently it can transmit, trade and consume that power.
