"Therefore the present system does not offer adequate assurance for assessment of coal quality and quantity thereby accuracy in computation of station heat rate (SHR) and specific coal consumption (SCC) of TPS. Tangedco should revamp the entire system of assessment of quality and quantity of coal in order to reduce the cost of generation and tariff, " the order quoted the CAG report.
CAG report recommended constituting a separate quality assurance wing for ensuring the quality of coal and all types of materials and equipment procured by Tangedco. It added that the coal procurement for both domestic and imported coal and quality assurance should be done by different agencies and the quality assurance wing head should directly report to the Director (Generation).
