Solar photovoltaic (PV) system

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

emissionssystem(s), which are assumed to be zero.

Monitoring parameters

F.1. Establishment of reference emissions
The default emission factor is set in a conservative manner for the Chilean regional grids: theCentral InterconnectedNational Electricity System (SENIC), the Northern Interconnected
System (SING), the Aysén system, and the Magallanes system.
The emission factor is calculated based on the conservative operating margin that reflects on
the latest electricity mix including low cost/must run resources for each regional grid in Chileduring 2014-2016-2018 and refers to the conservative emission factor of each fossil fuel power
plant in order to secure net emission reductions. The conservative emission factor of each plantis calculated to be 0.826 tCO2/MWh for coal-fired power plant and 0.364 tCO2/MWh for gasfired power plant based on the survey on heat efficiency of power plant in Chile. The emission
factor for diesel power plant is calculated to be 0.533 tCO2/MWh based on a default heatefficiency of 49%, an efficiency level which is above the value of the world’s leading diesel
power generators.
In case the solar PV system(s) in a proposed project activity is directly connected or connected
via an internal grid, not connecting to a captive power generator, to a regional grid (PV Case2

JCM_CL_AM001_ver021.0
Sectoral scope: 011), the value of operating margin including LCMR resources, using the best heat efficiency
among currently operational plants in Chile in calculating emission factors of fossil fuel power
plants, isare applied. The emission factors to be applied in this case are shown as “PV Case 1”
in section I of this methodology.
In the case the solar PV system(s) in a proposed project activity is connected to an internal gridconnecting to both a regional grid and a captive power generator (PV Case 2), the lower value
between emission factors shown as “PV Case 1” in section I of this methodology and theconservative emission factor of diesel-fired power plant of 0.533 tCO2/MWh is applied. Theemission factors to be applied in this case are shown as “PV Case 2” in section I of thismethodology.
In the case that the solar PV system(s) in a proposed project activity is only connected to aninternal grid only connecting to a captive power generator (PV Case 3), the emission factor ofa diesel generator calculated by applying the heat efficiency of 49%, an efficiency level which
is above the value of the world’s leading diesel generator, which is set to 0.533 tCO2/MWh, isapplied.
The emission factors to be applied in each case are shown in Section I. Data and parameters
