Nepal's Hydro-Dependence: A Flood-Exposed Vulnerability
Nepal's economic and energy ambitions, almost entirely underpinned by hydropower, have been starkly exposed by last Wednesday's devastating floods. A nation that exports nearly $200m annually in hydroelectricity to India and Bangladesh, and where 100% of its power comes from this single source, now faces an urgent reckoning with climate volatility.
The recent deluges, triggered by a collapsed glacier and its bedrock, did not merely cause widespread destruction; they severely damaged 12 hydropower plants within the Trishuli River basin. This single event obliterated more than 10% of Nepal's total power generation capacity, leaving operators uncertain if these critical facilities can ever be brought back online. For a country that only achieved 24 hours of power supply by 2018, having previously endured up to 16-hour daily cuts, this is a significant blow to hard-won energy security.
The state-owned Nepal Electricity Authority, owner of six of the affected plants, has reassured citizens of adequate supply for now. However, its spokesman, Rajan Dhakal, has publicly acknowledged the elephant in the room: "the time has come for a rethink of our hydropower policy." This candid admission underscores the gravity of the situation, especially given that preliminary investigations point to environmental factors in the high-altitude Himalayas, an area warming 50% faster than the global average. Nepal's Disaster Risk Reduction and Management Authority previously reported that over nine in ten disaster events between 2018 and 2024 were "related to climate."
**The Precariousness of Monoculture Energy**
Nepal's near-absolute reliance on hydropower, while yielding significant export revenue, illustrates the profound vulnerability inherent in a monoculture energy strategy. The destruction of 12 plants, capable of powering some three million households, highlights how a concentrated climate event can instantly undermine national economic stability and energy independence. The ongoing construction of hundreds more such facilities, mostly high in the mountains without substantial storage, intensifies this risk profile rather than mitigating it. The immediate economic implication is not just the cost of repairs, but the potential loss of $200m in export earnings, and the possibility of renewed energy imports to fill supply gaps.
**From Expansion to Resilience: A Policy Pivot**
The catastrophic deluge, which former Energy Minister Kulman Ghising described as a "once-in-a-century" event, serves as a harsh lesson for future infrastructure planning. Ghising's emphasis on designing plants that are "more resilient to the floods" and, critically, adopting "early-warning systems as well as robust emergency evacuation measures," signals a necessary policy pivot. The focus must shift from merely expanding capacity to embedding resilience against increasingly frequent and intense climate-related disasters. This change in thinking is imperative for an economy deeply intertwined with its mountainous geography and glacial water sources.
**Broader Implications for Infrastructure and Service Delivery**
The Nepalese experience holds a broader signal for developing economies reliant on specific geographical advantages for critical infrastructure. While Nepal leverages its fast-flowing mountain currents, the principle of climate vulnerability applies across various contexts. The immediate aftermath of such a disaster also throws into sharp relief the challenges of coordinating large-scale repair and reconstruction efforts. Repairing 12 damaged hydropower plants and potentially hundreds of mud-filled tunnels will demand a coordinated influx of skilled labour – engineers, technicians, and construction specialists. In situations requiring urgent service delivery, the efficiency of connecting demand with qualified supply becomes paramount. Platforms like SErraND | Plug Wa Kazi, designed to connect users with local service providers, could play a role in rapidly mobilising vetted expertise for critical infrastructure repair and disaster recovery, ensuring that the necessary skills are deployed precisely where and when they are needed most, bypassing the inefficiencies of fragmented informal systems.
Ultimately, Nepal's floods are a stark reminder that even a nation's most profound natural advantage can become its Achilles' heel without a robust strategy for climate resilience. The lesson is not to abandon hydropower, but to radically rethink how such vital infrastructure is designed, built, and protected in an era of escalating environmental risk.
