2 Cement Sector

3 Indian Cement Industry India is the second largest cement market in the world, accounting for about 6% of the world s cement production The cement industry uses coal and electricity as the main sources of fuel. Energy cost accounts for about 40% of the total manufacturing cost in some of the cement plants and coal accounts for 15% 20% of the total production costs. The specific thermal energy consumption and electrical energy consumption for state-of-the-art cement plants are as low as 658 kcal/kg of clinker and 65 kwh/ton of cement, respectively.

4 Indian Cement Industry (contd.) The specific energy consumption patterns of most of the plants very, having wide band variation. This happens mainly because of plants having different product mix based on addition of Pozzolona, Slag and Fly Ash and different blending percentage. The pure cement being Ordinary Portland Cement (OPC) and no dilution by additives, consumes the highest energy per ton. The blending with additives to manufacture other varieties reduces the Specific Energy Consumption per ton.

5 Indian Cement Industry (contd.) Because of these complexities, it becomes extremely difficult to come to a common model to arrive at standardized SEC per ton. Considering all these situations, the conversion factors and best possible combination and categorization have been worked out so that no Designated Consumer may have any grievance on the targets set out While setting targets, units best in the group as reference and then worked out targets for others.

8 Methodology for Baseline and EPIs (Summary) For each plant, different types of cement products and exported clinker are converted in to equivalent major product produced by that plant with the help of conversion factor, reported by the concerned plant. Thermal Energy Input is arrived at by taking all type of fuels into account. Electricity Purchased is converted in to equivalent thermal energy by multiplying it with 860. Whereas the electricity exported to grid is calculated similarly by multiplying it with 2717 (national avg. heat rate). Notional energy is also imposed on imported power Notional Equivalent Thermal Energy for Imported Power= Electricity purchased from Grid x (Weighted avg. heat rate of CPP of Cement plants-860).

9 Methodology for Baseline and EPIs (Summary) Total GtG Energy Consumption is calculated by adding the thermal inputs through all type of fuels, electricity purchased and subtracting the power exported to grid. Notional Energy (equivalent thermal energy) for Exported and Imported clinker are calculated based on thermal and electrical SEC reported by the concerned plant, wherein the Electrical kwh is converted into thermal kcal by multiplying the weighted average heat rate of the all form of electricity used in plant The notional energy required for exported/imported clinker is added to the total thermal and electrical energy consumed by the plant only to arrive at the Gate to Gate Sp. Energy Consumption.

10 Perform, Achieve and Trade (PAT) Scheme Normalization Factors (DRAFT) The following normalization factors have been considered in consultation with the Sectoral Expert Committee and various plants in the cement sector: a. Equivalent major grade of cement production The various product mixes are converted in to equivalent major grade of cement product by the plant by using the following formulae: i. Conversion of Ordinary Portland Cement (OPC) production equivalent to major product OPC Pr oduced(million Ton) Conversion fa ctorofopc Equivalent Ma jorpr oduct Conversion Fa ctorofma jorpr oduct [Million Ton] ii. Conversion of Portland Pozolona (PPC) Production equivalent to major product PPC Pr oduced(million Ton) Conversion fa ctorofppc Equivalent Ma jorpr oduct Conversion Fa ctorofma jorpr oduct [Million Ton] iii. Conversion of Portland Slag Cement (PSC)/any other variety of Cement Production equivalent to major product Equivalent Ma jorpr oduct PSCoranyothervarietyCement Produced(Million Ton) Conversionfac PSCoranyothervarietyCement ConversionFactorofMajorProduct iv. Conversion of Total Exported clinker to major product [Million Ton] TotalExportedClinker(Million Ton) Equivalent Ma jorpr oduct [Million Ton] Conversion Fa ctorofma jorpr oduct where: Total Exported clinker= [Clinker Exported to other plants + clinker exported to clinker stock over and above the opening stock,]

11 v. Conversion of Total Imported clinker to major product TotalImportedclinker(Million Ton) Equivalent Ma jorpr oduct [Million Ton] Conversion Fa ctorofma jorpr oduct where: Total Imported clinker= [Clinker Imported from other plants + clinker Imported from clinker stock, equivalent to the quantity by which the clinker opening stock gets reduced] vi. Total Equivalent major product of Cement It can be arrived at by summing up all the different grades of cements equivalent to major product calculated above: Total Equivalent major product of Cement = a(i) +a( ii) +a(iii) + a( iv) [Million Ton] Note: S.No. a(v) is already accounted in major product a. Calculation for Gate to Gate Specific Energy Consumption (SEC) i. Total Thermal Energy Consumption (Kiln + power Generation) Total Thermal Energy Consumptions to be calculated as:- Total Thermal Energy Consumption= [{Fuel consumed (kiln+ power generation) (Million Ton) X Gross calorific value of respective fuel (kcal/kg) X 1000}-{Electricity exported to grid (Million kwh) X 2717 (kcal/kwh)}] [Million kcal] where: kcal/kwh is the National Average Gross Heat Rate of Thermal Power Stations in the country in Note: - 1.With reference of definition of Energy as defined in the EC-ACT 2001, if biomas used in the Kiln (in case of a cement plant), it does not form a part of energy and its ene value is not to be accounted. But, if the same biomass is used in a captive power pla which is connected to the grid (whether exporting electricity or not), the same biom gets covered as energy and its energy value is to be considered. 2. Clinker opening and closing stock has now been incorporated in the form-1, which automatically generates the summary sheet once the data is filled in Form1. The surplus closing clinker stock in , with respect to clinker opening stock in base year ( ), has been considered for normalization as exported clinker. Similarly, the reduction in stock from the baseline has been considered as imported clinker and accordingly, it has been normalized as per the approved methodology. ii. Energy forimported Electricity Consumption Total energy for imported Electricity Consumption is to be calculated as:- Total energy for Imported Electricity=[{(Total Imported Electricity from grid (Million kwh) X 860(kcal/kWh)}] [Million kcal]

12 iii. Notional/ Normalization energy for Imported electricity from Grid Notional Energy for imported electricity= [{Imported Electricity (Million kwh) x ( ) (kcal/kwh)}] [Million kcal] where: 3208 kcal/kwh is the weighted average heat rate of captive power plants in all DCs in cement sector. iv. Notional/ Normalization energy for grinding of exported Clinker It is calculated by using following formula: Notional Energy =[{Total Exported clinker to major product (Million ton) X Electrical SEC of cement grinding (kwh/ton of cement) X Weighted Average Heat Rate (kcal/kwh)}] [Million kcal] where: -Weighted Average Heat rate (kcal/kwh) = [{Imported Electricity (Million kwh) X 3208 (kcal/kwh)} + {DG generation (Million kwh) x DG heat rate (kcal/kwh)} + {Captive Power Plant Generation (Million kwh) x Captive Power plant heat rate(kcal/kwh)}] / [Imported Electricity (Million kwh) +DG generation (Million kwh)+captive power plant generation (Million kwh)] v. Notional/ Normalization energy for clinkerization of imported Clinker It is calculated by using following formula: Notional Energy = Total Clinker imported (Million ton) x [(Thermal SEC of Clinkerization, kcal/kg clinker x 1000) +{Electrical SEC of Clinkerization (kwh/ton of clinker) x Weighted Average Heat Rate (kcal/kwh)}] [Million kcal] vi. Gate to Gate (GtG) Energy Consumption GtG Energy Consumption =b(i) +b(ii) +b(iii) +b(iv)+b(v) [Million kcal] vii. Gate to Gate (GtG) Specific Energy Consumption Gate to Gate (GtG) Energy Consumption (Million kcal) GtG SEC = Total Equivalent of Major Product of Cement (Million ton) X 1000 [ kcal/kg of equivalent cement]
