Renewable energy in Nepal

Renewable energy in Nepal is a sector that is rapidly developing in Nepal.[1] While Nepal mainly relies on hydroelectricity for its energy needs, solar and wind power is being seen as an important supplement to solve its energy crisis.

Nepal is one of three countries with the greatest increases in electricity access from 2006 to 2016, owing to grid-connected and off-grid renewables.[2]

Hydropower

According to one estimate, Nepal has a hydropower potential of 83,000 megawatts (MW).[3] Harnessing an estimated 40,000 MW is considered technically and economically feasible.[4]

Nepal currently has an installed capacity of 1,000 MW coming from 88 hydropower plants across the country.[5] Of this, 441 MW is produced by 60 hydropower plants owned by independent power producers.[5] Most of Nepal's hydropower plants are run-of-the-river, which causes electricity supply to fluctuate according to the season.[5]

As of March 2018, as many as 113 hydropower plants are under construction. These plants will have a combined capacity of 3,090 MW once completed.[5]

The Nepal earthquake in April 2015 is estimated to have destroyed at least 14 hydropower dams in the country,[6] accounting for 115 MW of hydropower facilities.[7] The earthquake affected 30 percent of Nepal's generating capacity at the time.[8] This resulted in suggestions for Nepal to diversify it energy mix, as well as for "short, medium and long-term energy planning to have reliable, secure and sustainable electricity provided to households, businesses and industries in the country."[7]

Solar energy
Solar potential of Nepal

Nepal gets most of its electricity from hydropower sources, but it is looking to expand the role of solar power in its energy mix.[9]

Power cuts with an average of 10 hours per day in the past time[10] had been common in Nepal and Nepal Electricity Authority[11] used to publish a time table for power cuts. Solar energy can be seen as a more reliable source of energy in Nepal than the traditional electricity. Private installations of solar panels are more frequent in Nepal.

Accordingly solar energy are used properly in Nepal but we can still improve more.

The People living in places such as Madi, Chitwan, where the Electricity Authority does not provide electricity[12] because of Chitwan National Park, have been relying on solar power[13] for several years.

Nepal began construction of its largest solar energy plant in April 2018 in the Nuwakot district. The project will have a capacity of 25 MW to serve the Kathmandu valley upon completion.[14][15]

In 2019, Nepal's Department of Electricity Development approved survey licenses for 21 locations to prepare for the possible installation of 56 solar plants, which could have a combined solar capacity of 317.14 MW.[9] The largest planned solar energy project is a 120 MW solar PV station in Dhalkebar in Mahottari district.[9]

Wind-solar energy

Nepal launched its largest wind-solar power system in December 2017 to serve rural households in the Hariharpurgadi village, Sindhuli district, under the  South Asia Subregional Economic Cooperation Power System Expansion Project.[16] The system has the capacity to produce 110 kilowatt-hours of energy per day.[16]

The country also operates a mini-grid wind-solar system in rural village of Dhaubadi the Nawalparasi district, which supplies 43.6 kilowatt-hours of energy per day.[17]

Electric vehicles

Electric powered[18] public three wheeler have been in use to reduce carbon dioxide (CO2) emissions. [19]

gollark: Doesn't work.
gollark: I have an environment table with new `fs` functions, and I want `loadfile` and `os.run` and whatever to use those.
gollark: Well, how am I supposed to make this work properly?
gollark: Er, no.
gollark: Why would you want to do that?
