Section 43(2) in Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2019
(2)Energy charge rate (ECR) in Rupees per kWh on ex-power plant basis shall be determined to three decimal places in accordance with the following formulae:(a)For coal based and lignite fired stations:ECR = {(SHR - SFC x CVSF) x LPPF / (CVPF + SFC x LPSFi + LC x LPL} x 100 /(100 - AUX)(b)For gas and liquid fuel based stations:ECR = SHR x LPPF x 100 / {(CVPF) x (100 - AUX)}Where,AUX =Normative auxiliary energy consumption in percentage.CVPF = (a) Weighted Average Gross calorific value of coal as received, in kCal per kg for coal based stations less 85 Kcal/Kg on account of variation during storage at generating station;(b)Weighted Average Gross calorific value of primary fuel as received, in kCal per kg, per litre or per standard cubic meter, as applicable for lignite, gas and liquid fuel based stations;(c)In case of blending of fuel from different sources, the weighted average Gross calorific value of primary fuel shall be arrived in proportion to blending ratio:CVSF = Calorific value of secondary fuel, in kCal per ml;ECR = Energy charge rate, in Rupees per kWh sent out;SHR = Gross station heat rate, in kCal per kWh;LC = Normative limestone consumption in kg per kWh;LPL = Weighted average landed cost of limestone in Rupees per kg;LPPF = Weighted average landed fuel cost of primary fuel, in Rupees per kg, per litre or per standard cubic metre, as applicable, during the month. (In case of blending of fuel from different sources, the weighted average landed fuel cost of primary fuel shall be arrived in proportion to blending ratio);SFC = Normative Specific fuel oil consumption, in ml per kWh;LPSFi = Weighted Average Landed Fuel Cost of Secondary Fuel in Rs./ml during the month:Provided that energy charge rate for a gas or liquid fuel based station shall be adjusted for open cycle operation based on certification of Member Secretary of respective Regional Power Committee during the month.
