India May Export Power to Nepal Following Flood Damage to Hydro Projects
In an unexpected shift in cross-border energy flows, India may export electricity to Nepal during a period when it usually imports power from its neighbour. The potential change comes as Nepal faces electricity shortages caused by recent flash flood damage across several of its power generation facilities.
What Happened
Flash floods on Wednesday struck Nepal, hitting 13 hydroelectric plants and one solar facility. The disaster affected roughly 360MW of electricity generation capacity, including the 14MW Devighat hydropower station, which is among the facilities that supply electricity to India.
Under normal circumstances, India relies on hydropower imports from Nepal during the high-demand summer months, whereas Nepal imports power from India during the dry winter when freezing rivers curtail its domestic generation. The sudden disruption to generation capacity may now require India to supply electricity to bridge Nepal’s supply deficit.
Key Highlights
- Flash floods in Nepal disrupted approximately 360MW of electricity generation capacity across 13 hydro plants and one solar project.
- The affected infrastructure includes the 14MW Devighat plant, which normally exports power to India.
- Hydropower represents more than 90% of Nepal’s total generation capacity of roughly 4,300MW.
- India’s current domestic power demand stands between 245GW and 250GW, below its peak capacity handling limit of 280GW.
- The cross-border Dhalkebar-Muzaffarpur 400kV line currently provides 1,000MW of electricity transfer capacity, with plans to expand combined transfer capacity to over 1,400MW.
Why This Matters
Hydropower is vital to Nepal’s energy grid, making up over 90% of the country’s total capacity of about 4,300MW. The disruption of 360MW is a notable short-term hit to domestic generation, overturning the typical seasonal dynamic where Nepal exports surplus power during the wet season.
From the Indian perspective, meeting a potential request from Nepal appears operationally viable. According to an official, India’s current electricity demand ranges from 245GW to 250GW, which is well below the national infrastructure’s capacity to manage peak loads of up to 280GW.
What to Watch Next
India could evaluate an electricity supply request if Nepal submits a formal appeal for assistance. Meanwhile, both nations will rely on existing cross-border transmission infrastructure, notably the Dhalkebar-Muzaffarpur 400kV line, alongside recently agreed plans to raise overall bilateral power transfer limits past 1,400MW.
Frequently Asked Questions
Why does the power flow between India and Nepal depend on the season?
India typically imports electricity from Nepal in the summer to help meet surging domestic demand, while Nepal imports power during the dry winter months when river flows decline and freeze, lowering hydropower generation.
How much generation capacity was affected by the flash floods?
The floods impacted 13 hydroelectric facilities and one solar installation, taking around 360MW of generation capacity offline.
Does India have enough spare capacity to support Nepal?
India’s domestic power demand is currently between 245GW and 250GW, leaving headroom below its operational capacity to handle peak demand of 280GW.
