Solar photovoltaic (PV) system

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

F.1. Establishment of reference emissions
The default emission factors are set in a conservative manner based on the Mongolian national
grid which consists of Central Energy System (CES), Altai-Uliastai Energy System (AUES),
Western Energy System (WES), Eastern Energy System (EES), and Southern (Gobi) Energy
System (SES) and based on the most efficient heat efficiency of a diesel power generator.
In order to identify the emission factor based on the national grid simplistically and secure netemission reductions, this methodology applies the lowest emission factor of coal-fired power
plant supplying electricity to the national grid, which is set to be 0.797 tCO2/MWh. This value
is lower than the grid emission factor for CES, which is 1.154 tCO2/MWh (combined margin,2012) published by Mongolian government, and it ensures net emission reductions.
In addition, the conservative emission factor based on a captive diesel power generator iscalculated by applying the default heat efficiency of 49%, an efficiency level which is above thevalue of the world’s leading diesel power generator, and set to 0.533 tCO2/MWh.

REp = ∑(EGi,p × EFRE,i )i

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

EGi,p: Quantity of the electricity generated by the project solar PV system i during theperiod p [MWh/p]

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

G. Calculation of project emissions
Project emissions are not assumed in the methodology as electricity consumption by any PVsystem is negligible.
PEp = 0PEp

: Project emissions during the period p [tCO2/p]

H. Calculation of emissions reductions
ERp = REp － PEp= REp
ERp: Emission reductions during the period p [tCO2/p]

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

PEp: Project emissions during the period p [tCO2/p]
