On wind energy in the Himalayas

Glaciological Expedition of Nepal, Contribution No. 76.

Abstract

The wind power available in the mountain and valley wind in the Nepal Himalayas is estimated through parameterization of the wind speed distribution by the Weibull distribution. The calculations were performed for winter, summer monsoon and pre-monsoon. The agreement between the actual wind and the Weibull distribution is good except in summer. The wind power in winter is 64 W/m², which is almost the same as that in the pre-monsoon season and twice that in summer. Extracted power from a wind driven generator was 49 % of the rated power in winter and 26 % in summer if the machine has a rated speed of 7 m/s.
