India Approves 654 MW Power Supply to Nepal: Energy Cooperation, Climate Risk & Neighbourhood First
Why in News?
India has approved the supply of up to 654 MW of electricity to Nepal for 18 hours a day until 31 December 2026, after a devastating glacier-collapse-induced flood damaged Nepal’s hydropower infrastructure and created a serious electricity shortage.
Under the arrangement, Nepal can import power from India between midnight and 6 PM. Up to 600 MW can be supplied through the Muzaffarpur–Dhalkebar 400 kV transmission line, while another 54 MW can flow through the Tanakpur–Mahendranagar 132 kV line.
The development is important not only as emergency assistance. It highlights the growing strategic role of cross-border electricity grids, regional energy integration and climate-resilient infrastructure in India–Nepal relations.
What Triggered Nepal’s Power Crisis?
Nepal’s electricity system is overwhelmingly dependent on hydropower.
Recent catastrophic flooding caused by a glacier collapse near the Nepal–Tibet region severely damaged the country's energy infrastructure. More than a dozen hydropower facilities were reportedly affected, forcing Nepal to suspend electricity exports and instead seek emergency imports from India.
This reversal is significant.
Nepal normally generates large quantities of hydropower during favourable water-flow conditions and has increasingly emerged as an electricity exporter to India.
The disaster temporarily changed that equation:
Hydropower damage → Domestic generation falls → Nepal stops exports → Electricity shortage emerges → Emergency imports from India
This shows how climate-related disasters can rapidly change regional energy flows.
What Has India Approved?
India has allowed Nepal to import electricity for 18 hours each day, broadly covering midnight to 6 PM.
The arrangement is expected to continue until 31 December 2026, after which the position can be reviewed depending on Nepal’s recovery and electricity requirements.
Two Important Transmission Links
Muzaffarpur–Dhalkebar line
- Voltage: 400 kV
- Approved supply: up to 600 MW
- Connects the Indian and Nepalese electricity systems at high capacity.
Tanakpur–Mahendranagar line
- Voltage: 132 kV
- Approved supply: up to 54 MW
Together:
600 MW + 54 MW = 654 MW
These transmission corridors are important Prelims facts because they represent the physical infrastructure supporting India–Nepal electricity trade.
Why Only 18 Hours a Day?
This is an interesting energy-policy aspect of the arrangement.
India itself is currently dealing with high electricity demand. The pressure becomes particularly strong during the evening and night, when solar generation falls.
During daylight hours, however, India's rapidly growing solar capacity can generate substantial electricity.
The approved Nepal supply therefore largely overlaps with hours when the Indian system has greater availability, especially during the daytime solar-generation period.
This illustrates a broader principle of modern electricity trade:
Power trade is not only about how much electricity a country produces — it is also about when electricity is available.
Why is Cross-Border Electricity Trade Important?
Electricity cannot easily be stored at very large scale without storage infrastructure.
At any moment:
Generation must broadly match demand.
Neighbouring countries with interconnected grids can therefore help each other when generation and demand patterns differ.
For example:
- Nepal can export surplus hydropower during high-generation periods.
- India can supply electricity when Nepal experiences shortages.
- India’s solar generation can complement Nepal’s hydropower profile.
- Regional grids can reduce the need for every country to maintain excessive backup capacity.
Thus, electricity trade can improve both economic efficiency and energy security.
India–Nepal Power Cooperation: From Buyer-Seller to Interdependent Grid
India and Nepal have cooperated in electricity and hydropower for decades.
The relationship has now expanded beyond simple bilateral electricity supply.
Nepal began purchasing electricity through Indian power exchanges in 2021 and subsequently also began selling electricity into the Indian market.
India's Ministry of Power has described a growing network of bilateral trade, transmission connectivity and hydropower cooperation between the two countries.
India has also been involved in several major hydropower projects in Nepal.
One important example is the 900 MW Arun-III Hydroelectric Project, being developed with Indian participation.
The 10,000 MW India–Nepal Vision
A major long-term objective of bilateral energy cooperation is the agreement aimed at facilitating the export of up to 10,000 MW of electricity from Nepal to India over ten years.
This reflects a fundamental shift in India–Nepal economic relations.
Nepal possesses enormous hydropower potential because of:
- Himalayan rivers,
- steep gradients,
- high rainfall,
- snow and glacier-fed river systems.
India, meanwhile, has:
- a very large electricity market,
- growing power demand,
- a large transmission network,
- increasing renewable-energy requirements.
This creates natural complementarity.
Nepal
Hydropower potential + Export opportunity
India
Large electricity market + Need for flexible clean power
Together, these conditions make energy one of the most promising pillars of bilateral relations.
Hydropower as a Bridge Between the Two Economies
Hydropower offers Nepal three major benefits.
Revenue
Electricity exports can generate foreign-exchange earnings.
Industrial Development
Reliable electricity can support manufacturing and infrastructure development.
Energy Transition
Hydropower can help Nepal maintain a relatively low-carbon electricity system.
For India, Nepalese hydropower also has strategic value.
Solar and wind generation are variable.
Hydropower can often provide more flexible generation and therefore potentially complement India's growing renewable-energy system.
Regional Electricity Grid: Beyond India and Nepal
The India–Nepal power relationship is part of a wider transformation in South Asia.
India already trades electricity with neighbouring countries such as:
- Nepal,
- Bhutan,
- Bangladesh.
Cross-border power arrangements can gradually create the foundation for a more integrated South Asian electricity market.
The potential model is:
Nepal/Bhutan hydropower + Indian solar & grid infrastructure + Bangladesh demand = Regional electricity integration
Such integration can improve energy security while reducing the overall cost of electricity.
India as a Regional Electricity Transit Country
India's geographical position gives it another important role.
Nepal and Bhutan are landlocked.
Bangladesh lies to India's east.
Any large-scale electricity trade among these countries often requires access to the Indian transmission system.
This gives India the potential to become a regional electricity hub and transit platform.
India’s Power Ministry documents already reflect increasing institutional arrangements for cross-border electricity trade with Nepal, Bhutan and Bangladesh.
Neighbourhood First Dimension
India’s emergency electricity approval also has diplomatic significance.
India–Nepal relations occasionally face disagreements over:
- boundaries,
- infrastructure,
- political perceptions,
- water resources,
- domestic political narratives.
But the two countries remain deeply connected through geography, trade, culture and people-to-people ties.
Rapid assistance during a crisis can create practical trust.
Therefore, energy cooperation supports India's broader Neighbourhood First Policy.
The message is simple:
Regional leadership becomes credible when neighbouring countries see India as a reliable partner during crises.
Disaster Diplomacy
The Nepal power arrangement is also an example of disaster diplomacy.
Disaster diplomacy refers to situations where humanitarian or disaster-related cooperation helps countries build communication and trust.
Electricity supply after a major natural disaster can:
- support hospitals,
- restore communications,
- keep water systems operating,
- help businesses reopen,
- reduce social disruption.
Energy assistance therefore becomes part of humanitarian relief.
Climate Change and Himalayan Hydropower
The disaster also raises a more difficult question.
Nepal has enormous hydropower potential, but Himalayan hydropower infrastructure is increasingly exposed to climate-related risks.
These include:
- glacier retreat,
- glacial-lake instability,
- flash floods,
- landslides,
- extreme precipitation,
- sediment flows.
A separate study released around the same period warned that the Hindu Kush-Himalayan region is approaching major ecological and water-security thresholds as glacier retreat accelerates.
This creates a paradox.
Hydropower can support clean energy.
But:
Climate change can make hydropower infrastructure itself more vulnerable.
Therefore, future hydropower planning must include climate resilience.
What is “Peak Water”?
Glacier retreat initially increases meltwater.
For some time, river flows may therefore increase.
But eventually glaciers become so reduced that meltwater begins to decline.
The point at which glacier-fed runoff reaches its maximum before beginning a long-term decline is often described as peak water.
For Himalayan countries, this matters because millions of people depend on glacier- and snow-fed river systems.
Potential consequences include:
Glacier loss → Changing river flow → Hydropower uncertainty → Agriculture stress → Drinking-water risk
Thus, Himalayan glacier change is not only an environmental issue.
It is also an economic, energy and national-security issue.
Why Himalayan Monitoring Matters
One major challenge is the limited monitoring of glaciers and glacial lakes.
Better monitoring requires:
- satellite remote sensing,
- automatic weather stations,
- river-flow monitoring,
- glacial-lake mapping,
- early-warning systems.
India has already increased attention to Glacial Lake Outburst Flood (GLOF) preparedness.
The Nepal disaster reinforces the need for cross-border Himalayan monitoring because river systems and glacier-related disasters do not respect political boundaries.
Is Every Glacier-Related Flood a GLOF?
No.
This is an important conceptual distinction.
A Glacial Lake Outburst Flood (GLOF) occurs when water stored in a glacial lake is suddenly released.
However, a flood can also be caused by:
- glacier collapse,
- ice or rock avalanche,
- landslide,
- extreme rainfall,
- combinations of these processes.
Therefore, unless scientific investigation confirms a glacial-lake breach, every glacier-related disaster should not automatically be called a GLOF.
This distinction is useful for both geography and disaster-management answers.
Climate Justice Angle
Nepal has also argued that poorer Himalayan countries suffer disproportionately from climate-related disasters despite contributing relatively little to historical global greenhouse-gas emissions.
This connects the disaster with the broader principle of climate justice.
Nepal has appealed for international financial assistance for reconstruction after the flood and linked the disaster to the vulnerability of developing countries to climate change.
This brings in several GS-III concepts:
- adaptation finance,
- Loss and Damage,
- climate justice,
- disaster-resilient infrastructure.
Why the Issue Matters for Bihar
There is also a direct State PCS relevance.
Bihar shares a long border with Nepal and many major north Bihar rivers originate in or flow through Nepal.
These include systems associated with:
- Kosi,
- Gandak,
- Bagmati,
- Kamla.
Extreme rainfall, landslides, dam operations and changing Himalayan hydrology can therefore affect flood conditions downstream in Bihar.
For BPSC candidates, the Nepal disaster should be linked with:
Himalayan climate change → Nepal river systems → North Bihar flood vulnerability
This demonstrates why India–Nepal water cooperation has direct consequences for Bihar.
India’s Solar–Nepal Hydropower Complementarity
One of the most interesting long-term possibilities is the complementarity between Indian solar power and Nepalese hydropower.
Solar electricity peaks during daylight.
Hydropower can potentially provide more flexible generation at other times.
With sufficient grid infrastructure and electricity-market coordination:
Daytime Indian solar + Flexible Nepal hydropower + Regional transmission = More resilient electricity system
This is exactly the kind of regional integration needed in a renewable-heavy future.
Challenges
Despite its potential, India–Nepal electricity cooperation faces several challenges.
Climate Vulnerability
Hydropower projects face floods, landslides and changing river flows.
Transmission Infrastructure
Large volumes of cross-border electricity require high-capacity transmission corridors.
Project Delays
Large hydropower projects often face financing, environmental-clearance and implementation delays.
Local Concerns
Hydropower projects can affect settlements, forests and local ecosystems.
Political Sensitivity
Water and hydropower agreements can become politically controversial in both countries.
Grid Management
Growing renewable electricity requires sophisticated balancing, storage and forecasting.
Way Forward
India and Nepal should move from individual electricity projects towards a comprehensive climate-resilient regional energy partnership.
This should include:
- stronger cross-border transmission lines,
- integrated electricity markets,
- common disaster-response protocols,
- glacier and river monitoring,
- climate-resilient hydropower design,
- early-warning systems,
- greater renewable-energy coordination.
India should also promote trilateral and subregional electricity trade involving Nepal, Bhutan and Bangladesh.
The ultimate objective should be a South Asian electricity architecture in which neighbouring countries can automatically support each other during shortages and efficiently trade surplus clean power during normal periods.
Conclusion
India’s decision to supply up to 654 MW of electricity to Nepal following the devastating Himalayan flood is more than short-term emergency assistance.
It demonstrates how energy security, climate resilience and foreign policy are becoming increasingly interconnected.
Nepal’s hydropower resources and India’s large electricity market create a natural basis for long-term cooperation.
But the recent disaster also shows that future energy infrastructure in the Himalayas cannot be planned using historical climate assumptions alone.
The deeper lesson is that the future of India–Nepal relations may increasingly depend on building not simply more power projects, but a resilient, interconnected and climate-ready regional electricity system.
