4. Energy Consumption Status
• Per capita energy consumption: 16 GJ
• Per capita electricity consumption: 120 kWh (225 kWh
in Developing Countries)
• Access to electricity: 76%, (61% grid, 15% renewable)
• Electricity as % of total energy consumed: 3%, mainly
from Hydropower.
• Grid Power capacity: 904.4 MW (851 hydro+53.4 diesel)
• Generates 525MW in winter (peak demand: 1414MW)

5. Classification of Hydropower in Nepal
- Pico Hydro: < 10 kW
- Micro Hydro: 10 - 100 kW
- Mini Hydro: 100 kW - 1 MW
- Small Hydro: 1 - 10 MW
- Medium Hydro: 10 - 50 MW
- Large Hydro: > 50 MW
In comparison to India’s classification
- Pico Hydro: < 5 kW
- Micro Hydro: 5 - 100 kW
- Mini Hydro: 100 kW - 1 MW
- Small Hydro: 1 - 25 MW
- Medium Hydro: 25 - 100 MW

6. Legal and Policy Environment
• Government has adopted the Hydropower
Development Policy of 2001 and encourages both local
as well as foreign investment, especially for the
development of SHP
Highlights of the Hydropower Development
Policy, Nepal 2001
• Development at an affordable price
• Uplift the living standard of the rural community
• Efforts to reduce the risk of investment
• To open market for sale of electricity both at
national and international level.
• Easy acess for foreigners to work in the country in
relation to the project implementation

7. Legal and Policy Environment
Government Agencies in the power sector
i. Ministry of Energy (MoE)
ii. Water and Energy Commission Secretariat (WECS) –
planning and policy research.
iii. Department of Electricity Development (DoED) –
licensing, facilitation, promotion, compliance monitoring
and project study (regulating body under Ministry of Energy).
iv. Nepal Electricity Authority (NEA) – public utility for
generation, transmission and distribution of electricity
(Government of Nepal undertaking company under Ministry of Energy).
v. Electricity Tariff Fixation Commission (ETFC) – tariff
setting

8. Legal and Policy Environment
Application Process for SHP
•Survey license.
 To study generation, transmission, distribution survey
To obtain survey license, desk study report should be
submitted.
•Operation lisence.
 Production License (for construction and operation of a
production facility).
 Transmission License (for construction and operation of
a transmission).
 Distribution License (for construction and operation of a
distribution facility).
For operation license, Feasibility Study Report along with Detailed
Financing Plan should be provided. Power Purchase Agreement between
the developer and potential energy purchaser should also be provided
• Electricity Act 1992: a legal basis for HP
development

9. Issues in SHP development in Nepal.
• Hydropower Financing
• Project financing is challenging
• Multiple agencies
• Lack of "one-stop shop" for hydropower
development
• NEA as a Single Buyer
• Single buyer
• "Affected" Communities
• Rising expectation among local residents
• Poor Road and Transmission Infrastructure
• High social overhead cost
– Risks: Hydrological Risks, Geological Risks, Unstable
political situation, Sediment problem

10. Addressing the Issues
• Affected parties as owners (10% share); 90:10
ratio for rural electrification
• Benefit sharing mechanism (downstream-
upstream)
• Better compensation mechanisms: open
negotiation for land acquisition
• Open public hearing during EIA
• Negotiated corporate social responsibility: road,
school, water supply, livelihood training, …
• Preference to local residents for long term
employment

11. Some evidences of Positive Impacts
• Back migration in Taplejung district
• Long queues of people to invest in
hydropower, mostly SHPs
• Load shedding free zones in remote areas
• Demonstrated increase in income generation
activities at SHP areas
• Better market access to local products
• Villagers welcoming SHP promoters: access to
market, health facilities during emergencies,
fire brigade, …
