1 Perform Achieve and Trade (PAT)- Methodology- Baseline Normalization, Energy Performance Indicators, Targets and M&V 4 th July,2012 K. K. Chakarvarti Bureau of Energy Efficiency New Delhi

2 NATIONAL MISSION FOR ENHANCED ENERGY EFFICIENCY (NMEEE) The National Action Plan on Climate Change was released by Prime Minister of India in June 2008 The Action Plan Outlines 8 Missions including National Mission for Enhanced Energy Efficiency (NMEEE)8 Missions The basic objective of the NMEEE mission is to ensure a sustainable growth by an approximate mix of 4 E’s, namely-Energy, Efficiency, Equity and Environment

3 NMEEE – Four New Initiatives Perform Achieve and Trade (PAT): A market based mechanism to enhance cost effec­tiveness of improvements in energy efficiency in energy-intensive large industries and facilities, through certification of energy savings that could be traded. Market Transformation for Energy Efficiency (MTEE): Accelerating the shift to energy efficient appliances in designated sectors through innovative measures to make the products more affordable Energy Efficiency Financing Platform (EEFP): Creation of mechanisms that would help finance demand side management programmes in all sectors by capturing future energy savings. Framework for Energy Efficient Economic Development (FEEED): Developing fiscal instruments to promote energy efficiency

5 Provisions in the Energy Conservation Act As per Section 14(g) of EC Act, 2001 “[Establish and prescribe such energy consumption norms and standards for designated consumers as it may be considered necessary: provided that the central government may prescribe different norms and standards for different designated consumers having regard to such factors as may be prescribed] the central government can stipulate energy usage norms for designated consumers.

6 The Energy Conservation (Amendment) Act, 2010 Main Amendments The Central Government may issue the energy savings certificate to the designated consumer whose energy consumption is less than the prescribed norms and standards in accordance with the procedure as may be prescribed. The designated consumer whose energy consumption is more than the prescribed norms and standards shall be entitled to purchase the energy savings certificate to comply with the prescribed norms and standards. The Central Government may, in consultation with the Bureau, prescribe the value of per metric ton of oil equivalent of energy consumed.

7 Perform, Achieve & Trade (PAT) Mechanism  The key goal of the PAT scheme is to mandate specific energy efficiency improvements for the most energy intensive industries.  The scheme builds on the large variation in energy intensities of different units in almost every sector, ranging from amongst the best in the world, to extremely inefficient units as well.  The energy intensity reduction target mandated for each unit is dependent on its current efficiency : the reduction target is less for those who are more efficient, and is higher for the currently less-efficient units.  The design of PAT is the result of extensive consultations over the last two years (2010-11 and 2011-12), which have contributed to its robustness and simplicity.

8 The energy usage pattern varies widely in industries of a particular sector due to various diversities like -Scale of Production (Installed Capacities) - Use of Raw Material - Process Technology - Vintage - O & M Practices - Type of Product Output etc. Factors of DiversityMost Affected Sectors a)Raw Material InputPulp & Paper, Fertilizer, Power Plant, Textile a)Quality of Raw Material / FuelAll sectors a)Process & TechnologyAluminium, Iron & steel, Chlor-Alkali, Paper a)Final Product outputTextile, Iron & Steel, Aluminium a)VintageAll Sectors a)Capacity UtililizationAll sectors Reasons for Large Energy Usage Bandwidth

11 PAT Scheme : Background & Scope  Covers 478 designated consumers in 8 sectors  All DCs consume about 165 million toe energy  Targets would be given to all DCs to achieve the same within a time frame -Achievement > Target E-Scerts -Achievement < Target Purchase E-Scerts / Penalty  The Energy Savings Certificates (ESCerts) so issued will be tradable on special trading platforms to be created in the two power exchanges (Indian Energy Exchange and Power Exchange India).  National Target = 6.686 million toe at the end of 1st PAT Cycle ( by 2014-15)

12 PAT Scheme : Approach Towards Target Setting  Establishment of Baseline : –As per reported data of 3 years (2007-08 to 2009-10) –Normalization Factors –Average of last 3 years value  Targets to be statistically calculated based on relative SEC approach after grouping the DCs suitably  The target reviewed by an expert committee before notification

13 Estimation of Energy Savings  Base: – Baseline Year : 2009-10 – Baseline Production (P base ) : Avg. of 2007-8, 2008-9 & 2009-10 – Baseline SEC (SEC base ) : Avg. of 2007-8, 2008-9 & 2009-10 – Target SEC (SEC target ) : SEC as estimated in 2014-15 – Target : % reduction from SEC base  Estimation of Energy Saving (TOE) : P base ( SEC base – SEC target )

14 National Energy Saving Targets under PAT (%) (2012-15)

15 Saving Target Baseline SEC Target SEC Achieved SEC Scenario 1 Scenario 2 Compliance Issued Escerts Purchase Escerts Penalty Concept of Target, Compliance, ESCerts & Penalty

16 Example  Specific Energy Consumption (SEC) in Baseline year: 10 TOE/unit of production  Baseline Production: 10000 units  Target: 4% reduction in SEC  SEC in the target year: 9.6 TOE/unit production  For ESCerts or Penalty: – Reduction requirement: 4000 TOE – Scenario 1 (Achieved SEC = 9.4): +2000 TOE(ESCerts) – Scenario 2 (Achieved SEC = 9.8): -2000 TOE (Penalty)

17 Market Design ESCerts are issued – When energy efficiency improvements surpass targets – With 1 toe = 1 ESCert – Banking of ESCerts allowed during each cycle 1 st cycle ESCerts to 2 nd cycle 2 nd cycle ESCerts to 3 rd cycle

18 Advanced ESCerts Baseline, SEC(b) = 10 toe/t Target, SEC (t) = 7 toe/t Achieved after year 1, SEC (a) = 8.5 toe/t Production = 10000 tons AFTER YEAR 1 ESCerts =[(SEC(b) – (SEC (b)– SEC (t))/3) – SEC(a)] x 80% x prod = ((10 – (10-7)/3) – 8.5)) x 0.8 x 10000 = (9-8.5) x 8000 = 4000 ESCerts Revised Target = SEC(t) – (ESCerts/Prod) = 7 – (4000/10000) = 6.6 toe/t

20 PAT for Cement Sector- A Case Example

21 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.

22 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.

23 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.

24 Normalization of Product Mix *CF (Conversion Factor)= Clinker used for x grade/Cement Production of x grade **Conversion of exported clinker to equivalent major grade cement = Clinker exported/CF of major grade cement Raw Material Cement Plant Clinkering Unit (Clinker Production) Grinding Unit Clinker + Gypsum+ additives* = Cement (OPC/PPC/PSC/any other Variety) *(fly ash/Slag/any other unit) Cement Plant Clinkering Unit (Clinker Production) Grinding Unit Clinker + Gypsum+ additives* = Cement (OPC/PPC/PSC/any other Variety) *(fly ash/Slag/any other unit) Clinker Imported from Other Unit Clinker Exported to Other Unit Cement Dispatched Conversion of Cement Equivalent to Major grade = (Cement production of a particular grade) X (CF* of Same grade)/(CF of Major grade) Total Cement Production Equivalent to major grade =Production of all grades of cement equivalent major grade + (exported clinker equivalent to major grade Cement)**

26 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).

27 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.
