coal,, the sample, gets dried in the process for determination of GCV for payment to the coal suppliers. As a result, payment was made without taking into account loss of heat value due to moisture, but the coal actually fired in the boilers had the moisture content. (iii) Energy tariff (as per formula mandated by CERC) is inversely proportional to GCV. A lower GCV would thus lead to ...
