Nepal is a mountainous country with a high potential for wind energy. On average, Nepal gets 18 hours of wind every day in particular areas and at least two days a week, it is really windy all over the country. The analysis done by the Solar and Wind Energy Resource Assessment concludes that about 6, 074 sq km of land all over the country has the potential for wind power with density greater than 300 watt per square meter. The analysis established that more than 3,000MW of power with an installed capacity of 5MW per sq km was possible and Kathmandu Valley alone was capable of producing 70MW, whereas two districts, Mustang and Manang, have a potential of more than 2500MW. Wind generation capacity is particularly high in the river corridors and mountain valleys.
Nepal has a very short history of utilising wind energy. The first attempt was made in Rampur, Chitwan in the early seventies followed by in Ramechhap in the late seventies, whereas the first wind turbine generator was installed in Kagbeni, Mustang in 1989 with two 10KW wind turbine generators. There were also other attempts made by Research Centre for Applied Science and Technology, Nepal Army, Practical Action, AEPC, Department of Hydrology and Meteorology (DHM) among others. These organisations have collected vital information regarding prospects of wind energy in Nepal while installing wind turbines in their selected sites.
AEPC has already collected wind data in more than eleven potential areas of the country whereas DHM has collected such data over 40 stations since 1967.
A modern large wind turbine is not practical in Nepal as the blades cannot be disassembled and need to be delicately handled, which requires good road access for transportation. So for the time being, smaller wind turbines are ideal for the country. The hill effect on wind turbines placed on hills provides additional benefits to the wind turbine projects in Nepal.
Surrounding mountainous range around the Kathmandu Valley is about 105 km and if small wind turbines as pilot project could be installed at an interval of 100 meters, it could generate about 5MW. If they are installed as a cluster, certainly more power could be obtained. Further, such turbines could also be installed in other windy locations around the country. The government needs to realise that there are other types of renewable energy sources than hydropower, and due attention should be given to them as well.
