A. Title of the methodology
Power Generation by Waste Heat Recovery in Cement Industry

B. Terms and definitions
TermsDefinitions

Waste heat

Heat generated from cement production facility which would
not have been recovered in the absence of the project.

Suspension Preheater boiler (SPboiler)

Boiler which recovers waste heat from a suspension
preheater, which pre-heats raw materials fed into a rotarykiln, to generate steam.

Air Quenching Cooler boiler(AQC boiler)
Waste Heat Recovery system(WHR system)

Boiler which recovers waste heat from an air quenchingcooler to generate steam.
Power generation system consisting of a SP boiler and/or
AQC boiler, turbine generator and cooling tower that utilizes
waste heat from cement production facility.

C. Summary of the methodology
Items
GHGemission

Summaryreduction Waste heat recovery (WHR) system which generates electricity

D. Eligibility criteria
This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The project utilizes waste heat from the 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

Cement factory where the project is implemented is connected to a grid systemand the theoretical maximum electricity output of the WHR system, which iscalculated by multiplying maximum electricity output of the WHR system by
the maximum hours per year (24 * 365 = 8,760 hours), is not greater than theannual amount of the electricity imported to the cement factory from the gridsystem:
During the previous year before the validation, if the validation of theproject 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 theproject.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated on the basis of net electricity generation by the project that
replaces the import of grid electricity to the cement factory where the project is implemented.
The quantity of electricity consumed by the WHR system except direct captive use of theelectricity generated by itself is subtracted from the quantity of the electricity supplied from theWHR system to the cement production facility to calculate net electricity generation.
In order to ensure conservativeness, the quantity of electricity consumption by the WHR system
except for the direct captive use of the electricity generated by itself, is calculated by using thetheoretically maximum load for the capacity of equipments in the above-mentioned WHRsystem.

G. Calculation of project emissions
Project emissions are not assumed in the methodology as the WHR system utilizes only waste
heat and does not utilize fossil fuels as heat source to generate steam for power generation,
which is prescribed in the eligibility criteria 3.
Therefore, the following formula is used to express the project emissions:
PEp = 0I-5

H. Calculation of emissions reductions
Emission reductions are calculated as the difference between the reference emissions andproject emissions, as follows:
ERp ＝ REp - PEpI. Data and parameters fixed ex ante
