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

Summary
reduction Displacement of grid electricity including national/regional andmeasuresisolated grids and/or captive electricity by installation andoperation of solar 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.

F.1. Establishment of reference emissions
The default emission factor is set in a conservative manner for the Indonesian regional grids. Theemission 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 Indonesia during theyear 2013-2015 and refers to the conservative emission factor of each fossil fuel power plant inorder to secure net emission reductions. The conservative emission factor of each plant arecalculated as 0.795 tCO2/MWh for coal-fired power plant and 0.320 tCO2/MWh for gas-fired power
plant based on the survey on heat efficiency of power plant in Indonesia. The emission factor fordiesel power plant is calculated as 0.533 tCO2/MWh based on a default heat efficiency of 49%, anefficiency level which is above the value of the world’s leading diesel power generators.

In case the PV system(s) in a proposed project activity is directly connected or connected via aninternal grid not connecting to either an isolated grid or a captive power generator, to anational/regional grid (PV Case 1), the value of operating margin including LCMR resources,2

calculated using the best heat efficiency among currently operational plants in Indonesia for theemission factors of fossil fuel power plants, are applied. The emission factors to be applied areshown in column “Emission factor for PV Case 1 (tCO2/MWh)” of Table 1 of the additional
information.

In case the PV system(s) in a proposed project activity is connected to an internal grid connecting toboth a national/regional, and an isolated grid and/or a captive power generator (PV Case 2), thelower values between emission factors shown in column “Emission factor for PV Case 1(tCO2/MWh)” of Table 1 of the additional information and the conservative emission factors ofdiesel-fired power plant of 0.533 tCO2/MWh is applied. The emission factors to be applied areshown in column “Emission factor for PV Case 2 (tCO2/MWh)” of Table 1 of the additional
information.

In the case that the PV system(s) in a proposed project activity is only connected to an internal gridconnecting to an isolated grid and/or a captive power generator (PV Case 3), the emission factor of adiesel generator calculated by applying a default heat efficiency of 49%, an efficiency level which isabove the value of the world’s leading diesel generator is applied, which is set as 0.533 tCO2/MWh.
The result of calculation for emission factors to be applied for each case is shown in Section I.
