INTRODUCTION OF NEPAL
• Landlocked country bordered to the north by China and east west and north by India• Country of Himalayas• Country of Mount Everest (Highest Peak in the World)• Country of Gautam Buddha: Light of Asia and founder of
BuddhismFig 1: Flag of NepalSource: nepalmaria.wikispaces.com
Area: 1,47,181 square kmAltitude: 8848 to 70 m Length: 880 km (East to West)Width: 240 km (North to South)

Nepal in Brief• Capital: Kathmandu• Population: Around 30 million• Religion: Hindu, Buddhist,
Muslim, Christian, etc.• Language: Over 70, Nepali as
official language• Climate: Cold climate in Mountain
to Tropical Climate in Tarai Region• Temperature: -30 degree Celsius in
the Mountain to 45 degree Celsius in Tarai

HYDRO ELECTRICITY IN NEPAL

Energy• Ability of a system to perform work• Energy can be renewable and non-
renewable• Renewable Energy: Solar, Wind, Tides,
Geothermal heat, etc.• Non-Renewable: Coal, Nuclear, Fossil
fuel
• “HYDROPOWER” is renewable energy

What is Hydropower?
• renewable energy contained in the flowing water• Electricity generated using hydropower
known as hydroelectricity• Converts kinetic energy of flowing or
falling water into electrical energy• HEP can be generated on a small scale
with a ‘run-of-river’ installation• Large scale with hydroelectric dam Fig 7: Typical Hydroelectric Dam

Pharping Hydropower Project• First hydropower plant in Nepal• Constructed on May 22, 1911 • One of the largest hydro-power projects in
the south Asia during that time• Had capacity of 500 KW• Its now open as a museum

Electricity in Nepal
• Water is an important natural resource in Nepal• Possess 2.27% of world water resources• Occupies 5% of total surface area• More than 6,000 rivers, travels 45,000km• Storage potential is estimated to be 88
billion cu.m• theoretical hydropower potential -83,000
MW; technically and economically viable potential- 43,000 MW• Installed capacity: 698 MW Fig 9 : Transmission Tower

Energy Sector Overview
• Most of the power plant is run-of-river type so high production during Monsoon season and deficit during dry season• Only one seasonal storage project in the
system• Shortage of power during dry season and
spill during wet season• Storage projects are needed to solve this
problem• Intra-National Grid is essential for the best
use of the hydro resources for mutual benefit Fig 10: Storage type Hydropower project

Classification of Hydropower in NepalS.No. Description Capacity1. Micro Hydro Power Upto 100 kW
2. Mini Hydro Power 100 kW-1000kW
3. Small Hydro Power 1000kW-10,000kW
4. Medium Hydro Power 10,000kW-100,000 kW
5. Large Hydro Power >100,000 kW

Some Under Construction Power Plants
S.No. Project Name Capacity(MW) Type
1. Upper Tamakoshi 456.00 Run of River
2. Chameliya 30.00 Run of River
3. Kulekhani III 14.00 Storage (Cascade of KL I & II)
4. Upper Trishuli 3-A 60.00 Run of River
5. Upper Trishuli 3-B 30.00 Cascade of 3-A
6. Rahughat 27.00 Run of River
Total Capacity 617.00

Conclusion
• Hydropower development is the key for economic growth of Nepal• Government has declared Energy crisis but yet to be approved by
parliament• No EIA is needed for small HPP• Establishment of large HPP by using high dam is necessary
