Data Availability Problems in Brazil and China Combined Margin Calculation under Data Constraints The following two cases (see Boxes 16 and 17) describe challenges encountered in the methodology application. Both cases are related to CM calculation under data constraints. Some key points are summarized below. However, it should be noted that these are the alternative approaches deemed appropriate in the context of Brazil and China. They might not be valid in other countries. The project boundary could exclude power plants where necessary data for emission factor calculation is not publicly available. However, it should be justified that the project is unlikely to affect the excluded power plants. In addition, it is also important that the selected grid boundary consists of a majority share of the total installed capacity in the relevant geographical area. Data Hierarchy In the absence of plant-specific data (e.g. fuel consumption, power generation), the following approach could be considered as alternatives for grid emission factor calculation: • OM calculation: Calculate the average emission factor for the grid for each fuel type (based on the average efficiency of the existing power plants); and • BM calculation: Apply conservative proxy for power plant efficiency for each fuel type (e.g. the efficiency level of the best technology commercially available in the relevant geographical area) to calculate fuel consumption necessary for the BM calculation. The use of the average efficiency of existing power plants is unlikely to be accepted because it would not lead to conservative BM calculation. In case plant-specific power generation data is not publicly available, more aggregate data (e.g. capacity addition from one year to another) could be used as an alternative for the selection of power plants for the BM calculation. 50
Box 16: OM/ BM calculation where the necessary data is not publicly available (Brazil) CM Calculation in Brazil National Grid Definition in Brazil Default Plant Efficiency Factors for Brazil “Request for guidance: Application of AM0015 (and AMS-I.D) in Brazil” 230 asked for the following two deviations: (i) electricity system boundary for Brazil be restricted to National Electricity System Operator (ONS), and (ii) average plant efficiency of power plants by fuel types be used in stead of actual fuel consumption. These two deviations are due to the fact that (i) the ONS dataset does not include power plants that are locally dispatched and the data for the remaining plants is not publicly available, and (ii) the fuel consumption data of the relevant power plants is not publicly available. The first deviation was accepted based on the following justifications: • ONS represents about 80% of the total installed capacity; and • The remaining plants outside ONS were unlikely to be affected by the project because they were operating based on power purchase agreements which were not under control of the dispatch authority, or located in noninterconnected systems to which ONS has no access. 231 The second deviation was not accepted for calculation of the BM emission factor because it would not lead to conservative estimation of emission reductions. Instead, the EB recommended the use of conservative proxy for power plant efficiencies to calculate the BM emission factor for grid electricity in Brazil: • Combined cycle gas turbine power plants: 50% • Open cycle gas turbine power plants: 32% • Sub-critical coal power plants: 33% • Oil based power plant sub-critical oil boiler: 33% 230 See “Request for guidance: Application of AM0015 (and AMS-I.D) in Brazil”, available at: http://cdm.unfccc.int/ UserManagement/FileStorage/66CDZWPJFJOOUFJ8HALRB1VZV7UC84 231 See the EB response to the request for deviation, available at: http://cdm.unfccc.int/UserManagement/ FileStorage/AM_CLAR_IF26PUYWE8666VS24I68BM8WBDWJTO. 51
