New Delhi: The Comptroller and Auditor General of India (CAG) in its performance audit report released on Monday slammed the government-owned hydro power companies for under utilisation of power stations in terms of capacity.
The national auditor claimed that the installed capacity and generation of hydro projects compared to the total installed capacity and generation was only 15.19 percent and 12.38%, respectively, as on March 31, 2015. The ideal energy mix required for optimal utilisation of installed capacity is 60% thermal and 40% hydro.
"The average capacity utilisation factor (CUF) of Bairasiul, Teesta-V, Chamera-III, and Chutak power stations of National Hydroelectric Power Corporation Limited (NHPCL) during the period covered by the performance audit were below their respective design CUFs," CAG report reads.
It also pointed that inadequate release and non-maintenance of prescribed reservoir levels, gross and live reservoir capacities of three NHPC power stations came down drastically during the last five years ended on March 31, 2014.
"A large number of instruments installed at dams and other structures to monitor their health were not in working condition," the report said.
The other CAG findings are: Disaster management plans of all power stations selected for the performance audit except Indira Sagar power station of NHDC were not in accordance with the Central Water Commission (CWC) guidelines.
The report also urged the Union power ministry to ensure the necessary action for increased monitoring and compliance with regulations.
