Definitions

Solar photovoltaic (PV) system

An electricity generation system which converts sunlight into
electricity by the use of photovoltaic (PV) modules. The
system also includes ancillary equipment such as inverters
required to change the electrical current from direct current(DC) to alternating current (AC).

Summary
reduction Displacement of grid electricity and/or captive electricity using

measuresdiesel fuel as power source by installation and operation of thesolar PV system(s).

Calculationofreference Reference emissions are calculated on the basis of the ACemissions

output of the solar PV system(s) multiplied by either; 1) theconservative emission factor of National Grid electricity or 2)
the conservative emission factor of diesel power generator in
off-gird area.

Calculationofproject Project emissions are the emissions from the solar PV system(s),emissionswhich are assumed to be zero.

Monitoring parameters

The quantity of the electricity generated by the project solar PVsystem(s) and category of the day d.

D. Eligibility criteria

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

The project installs solar PV system(s).

Generation of electricity from solar PV system(s)N/AF. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Considering that the flowing electricity of Cambodian grids is consisted of electricity generated
by coal-fired power plant, oil power plant, hydropower plant, biomass power plant andimported electricity, the conservative operating margin is applied to reflect an electricity mix in
National Grid of Cambodia in order to secure net emission reduction. Due to the limited datafor heat efficiency of each power plant, the emission factor for each electricity source is set to0.750 tCO2/MWh for the coal-fired power plants and 0.533 tCO2/MWh for the oil-fired power
plants which is calculated by applying the default heat efficiency of 49%, an efficiency level
which is above the value of the world’s leading diesel power generator. Since those emission
factors have not been achieved in Cambodia, they lead to net emission reductions. For theemission factor of import electricity, the hydropower plants and the biomass power plants, 0tCO2/MWh is applied. As a result, in case the PV system in a proposed project activity isconnected to the national grid, the emission factor is calculated to be 0.353 tCO2/MWh. In case
the PV system in a proposed project activity is connected to an internal grid which is notconnected to the national grid, the emission factor is set to 0.533 tCO2/MWh.

For calculation of reference emissions, either Case1 or Case 2 is selected.
Case1: If the project PV system supplies electricity to a national grid or the annual businessdays of the facilities to which the project PV system supplies electricity are 365 days or366 days, the following formula is applied.

REp: Reference emissions during the period p [tCO2/p]

EGi,p: The quantity of the electricity generated by the project solar PV system i during
the period p [MWh/p]

EFRE, i : The reference CO2 emission factor for the project solar PV system i [tCO2/MWh]
Case2: If the project PV system does not supply electricity to a national grid and the annual
business days of the facilities to which the project PV system supplies electricity are lessthan 365 days, the following formula is applied.

REp: Reference emissions during the period p [tCO2/p]

EGi,d: The quantity of the electricity generated by the project solar PV system i on
monitoring date d during the period p [MWh/p]: Category of the day d. [1 for business days, 0 for holidays]

EFRE, i : The reference CO2 emission factor for the project solar PV system i [tCO2/MWh]
