Climate Resilience and Decarbonization

Two linked questions

Decarbonization asks how renewable electricity can displace fossil fuels in cooking, transport and industry. Resilience asks whether the electricity system can withstand changing hydrology, floods, landslides, sediment, glacier-related hazards and heat. A low-carbon system can still be fragile; a resilient project can still impose environmental or social costs.

Official targets

Nepal's NDC 3.0 (Nepal Nationally Determined Contribution 3.0 (2025)) targets renewable electricity capacity of 14,031 MW by 2030 and 28,500 MW by 2035, expanded electric cooking and transport, lower system losses, smart metering and demand-side management. It also identifies adaptation priorities and states that most targeted emissions reductions depend on international climate finance and support.

These targets describe direction and ambition. They do not establish an executable project sequence or current delivery.

System exposure

Hydropower depends on climate-sensitive river flow and is exposed to extreme events, sediment and access disruption. The September 2024 floods and landslides affected operational projects with more than 600 MW of combined capacity in the World Bank's 2025 account (World Bank Nepal Country Economic Memorandum (2025)). On one corridor alone, the Rasuwa Bhote Koshi–Trishuli saw three damaging events in 26 months: the September 2024 floods, the July 2025 Purepu glacial-lake outburst and the 26 August 2026 Langtang Lirung avalanche flood, which washed away the 111 MW Rasuwagadhi plant (Bhotekoshi–Trishuli Flood 2026, GLOF Risk). Solar diversifies hydrological exposure but introduces land, grid, forecasting and evening-balancing needs.

Evidence discipline

Climate-adjusted project design should rely on a dated, published method or project study. General glacier or basin research cannot by itself prove the future design flow of an individual plant. The climate-design Decision Dossier therefore separates the policy question from the evidence currently available.

Evidence gaps

• Comparable project-level climate-adjusted hydrology studies.
• Public hazard and downtime records tied to individual assets.
• Climate stress tests for transmission and distribution.
• Costed links between NDC targets, finance and delivery institutions.
• Lifecycle emissions and adaptation trade-offs across portfolio options.
