The largest available renewable energy resource in Nepal is hydropower, which has a theoretical potential of approximately 83,000 MW. While economically viable hydropower capacity stands at 42,000 MW, the current installed capacity is only approximately 1182 MW. In FY 2018/19, NEA’s hydropower plants, including small ones generated a total of 2,548.11 GWh of electricity, and the total power purchased from Independent Power Producers (IPPs) within Nepal was 2,190.05 GWh. In addition to hydropower, Nepal also possesses other renewable resources with significant potential, including solar, wind and biomass. In the case of Solar PV systems, Global Horizontal Irradiation (GHI) (kWh/m2/day) is used as a reference value for comparing geographical conditions. The highest GHI up to 5.5 kWh/m2/day or higher has been identified in the northwest of the country while the average daily GHI values are between 4.4 kWh/m2 and 4.9 kWh/m2 in southern parts of the country. In addition to this, on average Nepal receives more than 300 sunny days per year, much higher as compared to most of the European Countries. According to Global Wind Atlas, Nepal has a mean power density of 608 W/m2 at the height of 50m with average wind speed of 8.94 m/s for the 10% windiest area in the selected regions.
