Eligibility Criteria - Approved Methodology ID_AM001
Criterion 1

The project utilizes waste heat from a cement production facility by waste
heat recovery (WHR) system to generate electricity

Criterion 2

WHR system consists of a Suspension Preheater boiler (SP boiler) and/or Air
Quenching Cooler boiler (AQC boiler), turbine generator and cooling tower

Criterion 3

WHR system utilizes only waste heat and does not utilize fossil fuels as a heatsource to generate steam for power generation

Criterion 4

WHR system has not been introduced to a corresponding cement kiln of theproject prior to its implementation

Criterion 5

The cement factory where the project is implemented is connected to a gridsystem and the theoretical maximum electricity output of the WHRsystem, which is calculated by multiplying maximum electricity output of theWHR system by the maximum hours per year (24*365=8,760 hours), is not
greater than the total amount of the electricity imported to the cement
factory from the grid system:> During the previous year before the validation, if the validation ofthe project is conducted before the operation of the project, or> During the previous year before the operation of the project, if thevalidation of the project is conducted after the operation of the projectCriterion 6

The WHR system is designed to be connected only to an internal power gridof the cement factory.

Reference Emissions
Reference
Reference is the situation where WHR system has not been
introduced. Diffusion rate of WHR system is very low inIndonesian Cement Industry
1 plant installed / 25 plants total

ConservativenessElectricity consumption of WHR system is calculated by thetheoretically maximum load of auxiliary equipment=> Rated capacity of installed equipment (EGCAP) related to WHR
system and max. hours/period

Emission Reduction / MonitoringEmission Reductions = Reference Emissions
Replacement of Grid Electricity Generation
 Calculation of reference/project emissions
Emissions to be calculated in the methodology arethose replaced by power generation of WHR system
 Emission Reductions= Reference Emissions – Project Emissions
 No additional fuelProject Emissions = 0
