Nepal's Flood Disaster Deals Blow to Hydropower Economy, 431 Megawatts of Power Vanish Instantly

Recent floods in Nepal destroyed multiple hydropower facilities, resulting in the instant loss of 431 megawatts of power. The country was forced to halt electricity exports to India and resume imports. Experts warn that climate change is exacerbating hydropower risks in the Himalayas, posing severe challenges to Nepal's hydropower economy.

Floods Devastate Hydropower Infrastructure, Shattering Nepal's Electricity Export Dreams

Nepal recently suffered severe flooding that damaged multiple hydropower facilities, causing an instant loss of 431 megawatts (MW) of power generation capacity. The disaster forced Nepal to suspend some of its electricity exports to India and resume imports from India to maintain domestic power stability. The Nepalese government initially estimated the economic loss from this disaster at 50 billion USD, equivalent to one-tenth of the country's annual gross domestic product (GDP).

Nepal's hydropower sector has developed rapidly in recent years. Currently, over 200 hydropower plants are operational, with an additional 142 projects under construction, totaling 4,303 MW in capacity, and 148 projects in development, totaling 4,203 MW. In the 2024-2025 fiscal year, Nepal exported electricity worth 17.47 billion Nepalese rupees (NPR) to India, while importing only 12.92 billion NPR, marking its first year as a net electricity exporter. However, the recent floods disrupted Nepal's export plans, pushing the country back into import dependency.

Nepal has a population of approximately 30 million, with chronic underemployment driving around 600,000 workers abroad annually to countries such as Qatar, Saudi Arabia, and Malaysia. Workers overseas often earn monthly incomes of less than 400 USD, but their remittances account for over a quarter of Nepal's GDP, forming a critical pillar of the national economy. However, the remittance-driven economy has also triggered a 'Dutch Disease' effect, inflating domestic consumption and prices while eroding the international competitiveness of other export industries. Hydropower was once seen as the key to reducing Nepal's reliance on remittances, but this disaster has exposed the sector's vulnerability.

Climate Change Amplifies Hydropower Risks in the Himalayas

The advantages and risks of Nepal's hydropower sector both stem from the Himalayas. The country's theoretical hydropower potential reaches 43,000 MW, far exceeding its current development scale. However, climate change is transforming the ecological environment of the Himalayas. Glacier melt, permafrost degradation, increased frequency of extreme rainfall, and declining slope stability are challenging traditional hydropower risk assessment methods. This flood disaster has highlighted the vulnerability of hydropower infrastructure under extreme climate conditions, and future projects may face compounded risks such as ice avalanches, rockslides, and glacial lake outburst floods.

Approximately 90% of Nepal's electricity system relies on hydropower. This disaster has not only affected domestic power stability but also disrupted electricity export plans to India and Bangladesh. Experts warn that as climate change intensifies, hydrological conditions in the Himalayas will become increasingly unpredictable. Nepal's hydropower industry must urgently adjust its risk assessments and infrastructure designs to cope with more frequent extreme climate events.

Nepal has yet to fully recover from the 2015 earthquake, and this flood disaster has undoubtedly placed an even heavier burden on the country's economy. Hydropower is not only the cornerstone of Nepal's power grid but also a vital source of economic growth and export revenue. However, the uncertainties brought by climate change pose severe challenges to the sustainability of Nepal's hydropower economy. The government and industry must reassess hydropower development strategies to address the escalating climate risks.
