Abstract
One of the main reasons of power cuts is the outage in power plants due to various problems in electro-mechanical components along with civil structure. This report focuses on the reason of power outage due to mechanical problems in powerhouse. The frequent problems in mechanical components were identified in selected hydropower which are Kali Gandaki Hydropower Plant, Middle Marsyangdi Hydro Power Plant and Marsyangdi Hydro Power Plant and found that the desander and the water-cooling system encountered the problems more frequently. This report calculates the outage hours due to maintenance and due to unexpected problems and makes a financial evaluation of the loss occurred in the last four fiscal years along with the performance analysis. The availability of these plants ranges from 70-85% and the reliability is found to be more than 98%. The average plant factor ranges from 68-73% with MHPP at highest (72.13%). The average capacity factor ranges from 93- 110% with MMHPP at highest (109.20%). Similarly, the average performance factor of the plant ranges from 92-98% with KGAHPP at highest (97.52%). Moreover, the generation cost per unit electricity is also calculated from the collected data.
