Micro and macro factors hindering generation in Nepal

Nepal's economically feasible hydropower potential is commonly quoted as about 42,000 to 45,000 MW (theoretical about 83,000 MW), but only a small fraction (a few thousand MW) has been developed. The barriers can be grouped into macro (national/policy/economic level) and micro (project/local level) factors.

Macro factors

1. Policy and institutional instability: frequent changes of government and policies; slow licensing and approval; overlapping authorities (DoED, NEA, Investment Board, ministries).
2. Lack of capital and investment: hydropower is capital intensive; limited domestic capital markets, high interest rates, perceived country risk for foreign investors.
3. Limited market and power trade: small domestic demand, low per-capita consumption; wet-season surplus but dry-season deficit; power trade with India/Bangladesh depends on cross-border agreements and transmission.
4. Weak transmission infrastructure: delays in building transmission corridors, so completed plants cannot evacuate power (spill of energy).
5. Power purchase agreement (PPA) issues: delays and limits on PPAs by NEA, take-or-pay concerns.
6. Geopolitical and regional issues: dependence on neighbouring countries for market and equipment.
7. Lack of integrated water resource and energy planning; preference for run-of-river (ROR) plants, few storage projects, causing seasonal mismatch.
8. Natural factors at national scale: monsoon-dependent flow, climate change, glacier lake outburst floods (GLOF), earthquakes.

Micro factors

1. Land acquisition and compensation disputes; local protests and demands for shares, jobs, royalties.
2. Difficult geography and access: lack of roads to remote sites raises cost and time.
3. Geological problems: weak young Himalayan rock, landslides, tunnelling difficulties; sediment load damaging turbines.
4. Environmental and social issues: forest clearance, resettlement, fish migration, EIA delays.
5. Lack of skilled manpower and local technology; imported equipment, foreign contractors.
6. Contractor and management problems: cost and time overruns (e.g. delays in some large projects).
7. Inadequate hydrological and geological data for design.
8. Local security issues, strikes and bandhs.

Remedies (brief)

One-window approval, stable policy, cross-border transmission and export agreements, more storage and pumped-storage projects, domestic investment through public shares, better local benefit sharing and timely transmission construction.
