A severe disaster unfolded along the Himalayan river basins as catastrophic flash floods and landslides caused extensive damage to critical hydropower infrastructure across central Nepal. State energy officials reported that rising waters and thick debris flows severely crippled multiple regional power plants, cutting local grid capacity significantly and prompting Kathmandu to request emergency, advance power imports from India to avert widespread blackouts. Emergency search-and-rescue teams, backed by international technical crews and specialized disaster management units, are working around the clock under hazardous weather conditions to locate hundreds of workers and local residents feared trapped inside inundated power tunnels and remote settlements. Neighboring Indian border states have simultaneously issued flood warnings along downstream river corridors, dispatching medical logistics, forensic teams, and transport assistance to aid ongoing multi-national evacuation and recovery operations. Glacial Surge and Debris Flow Devastate Power InfrastructureNepal’s national energy grid faces a critical power deficit after catastrophic flash floods struck the northern mountain river corridors of Rasuwa and Nuwakot districts. Triggered by an ice-and-rock avalanche and glacier collapse near the border with Tibet, a sudden, massive wave of water, silt, and mountain debris surged down the Lhende Khola into the Bhote Koshi and Trishuli Rivers. The raging torrent destroyed critical civil infrastructure, swept away 32 bridges, damaged main transport arteries, and inflicted severe structural damage on multiple operating hydroelectric plants and power transmission grids along the valley floor.

High-capacity generation sites, including the 111 MW Rasuwagadhi Hydroelectric Project and downstream stations along the Trishuli river basin, suffered extensive mud inundation and turbine damage. Additionally, secondary solar and local micro-hydro plants along the belt were knocked offline. High-voltage transmission pylons were destabilized or swept away, severing high-capacity power lines that route electricity southward to urban load centers, including the Kathmandu Valley.Emergency Power Imports and Long-Term Recovery OutlookWith more than 700 MW of generation capacity abruptly removed from the national grid, the Nepal Electricity Authority (NEA) instituted emergency power management protocols to prevent widespread grid failure. To offset the severe shortfall, Nepal increased emergency electricity imports from neighboring India through cross-border transmission links while prioritizing power allocation for critical hospitals, emergency command centers, and drinking water facilities. Energy experts note that while minor electrical repairs can restore partial capacity in coming weeks, clearing submerged powerhouses and repairing heavy structural dam damage across hard-hit installations will require months of intensive civil engineering recovery.
