Nepal is rich in water resources with multiple sources of water, including glaciers, snowmelt from the Himalayas, rainfall and ground water. There are 6,000 rivers, including rivulets and tributaries, totalling about 45,000 km in length. The country is contains 2.2% of the world’s water resources.
Nepal’s theoretical capacity for producing power from hydropower projects is around 80,000 MW. However, as at 2014, installed capacity is only around 700 MW of electricity, despite the fact that demand is over 1,000 MW. Thus, Nepal remains one of the lowest energy consuming countries in the world. Demand for electricity is increasing at 7–9% per year, and according to the forecast from Nepal Electricity Authority, demand for electricity will reach 3,600 MW by 2027.
