Definitions

Cogeneration System (CGS)

A system that consists of power generator(s) and boiler(s)supplying both electricity and heat, recovering waste heatexhausted by the power generator(s). The power generator isa gas engine in this methodology.

Facility

A cluster of buildings and/or plants (or building/plant itself)
to which electricity and heat generated by CGS is supplied.

Power Generation Efficiency

Net quantity of electricity generated per quantity of energy
contained in fuel fired in the power generator.

Boiler Efficiency

Net quantity of heat generated per quantity of energy
contained in fuel fired in the boiler.

C. Summary of the methodology
Items

emissionmeasures

Summary
reduction Electricity and heat generated by CGS(s) installed in the project
facility(ies) substitutes all or part of grid and/or captive
electricity consumed and heat generated by fossil fuel, whichleads to efficient energy use of the facility(ies) and in turn GHG
emission reductions.

Calculation
emissions

ofreference Reference emissions are CO2 emissions from the use of grid
and/or captive electricity and heat generated by reference boiler
in the facility(ies), which are calculated based on: the amount ofelectricity consumption by the facility(ies) which is generated
by the CGS(s); the amount of heat consumption by thefacility(ies) which is generated by the CGS(s); reference boiler
efficiency; and CO2 emission factors for consumed electricity2

JCM_ID_F_PM_ver01.0

and fossil fuel consumed by the reference boiler in thefacility(ies).
Calculation

ofproject Project emissions are CO2 emissions from the use of CGS(s),emissions

which are calculated based on: the amount of gas fuelconsumption by the CGS(s); net calorific value of gas fuelconsumed by the CGS(s); the amount of electricity consumption
by auxiliary machine(s) of the CGS(s); and CO2 emission factor
for gas fuel consumed by the CGS(s) and consumed electricity.

Monitoring parameters

 Amount of electricity consumption by the facility(ies) whichis generated by the CGS(s) [MWh/p]
 Amount of heat consumption by the facility(ies) which isgenerated by the CGS(s) [GJ/p] (Option 1)
 Amount of heat supply to the facility(ies) which is generated
by the CGS(s) [GJ/p] (Option 2)
 Number of days during the monitoring period [day] (Option2)
 Amount of gas fuel consumption by the CGS(s) [Nm3/p]
 Amount of electricity consumption by auxiliary machine(s)of the CGS(s) [MWh/p]

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated based on: the amount of electricity consumption by thefacility(ies) which is generated by the CGS(s); the amount of heat consumption by thefacility(ies) which is generated by the CGS(s); reference boiler efficiency; and CO2 emission
factors for consumed electricity and fossil fuel consumed by the reference boiler in thefacility(ies).
A default value for the reference boiler efficiency is conservatively set ex ante to 89.0 [%] so as
to ensure net emission reductions.

Option 2 can be selected when the project participants monitor the amount of heat “supply”,
instead of “consumption”, and there has existed boiler(s) generating steam and/or hot water andsupplying to the facility prior to the implementation of the JCM project. In this option, noemission reductions can be claimed from the amount of heat supply to the facility j which isgenerated by the CGS i exceeding the maximum capacity of heat generation by the existingboiler(s) supplying to the facility j.
