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).

C. Summary of the methodology
ItemsGHGemission

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

measuresfossil 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)
conservative emission factor of the grid, or 2) conservativeemission factor of the captive diesel power generator.

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).

Generation of electricity from solar PV system(s)N/AF. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
The default emission factor is set in a conservative manner for the connected Lao Power Gridand Thailand Power Grid (hereafter referred to as “Lao-Thailand Power Grid”), which isdefined as one interconnected electricity system.
Natural gas-fired power plants hold the majority (70%) in overall power supply to theLao-Thailand Power Grid for the last five years. Emission factor of the electricity system is thus
calculated in a conservative and simple manner based on the emission factor of gas power
plants in order to secure net emission reductions. The calculation applied the emission factor ofnatural gas and the efficiency of the most efficient natural gas-fired power plant which supplies
generated power to the grid (efficiency: 61.2%). As a result, the emission factor for the grid is
set to be 0.319 tCO2/MWh.
In addition, assuming captive power plants to be diesel power plants, whose emission factor iscalculated to be 0.533 tCO2/MWh based on a default heat efficiency of 49%, an efficiency level2
