F.1. Establishment of reference emissions
The default emission factor is set in a conservative manner for the Philippines regional grids:
Luzon-Visayas and Mindanao systems.
The emission factor is calculated based on the conservative operating margin that reflects on
the latest electricity mix including low cost/must run (LCMR) resources for each regional gridin the Philippines during 2015-2017 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 plant is calculated to be 0.826 tCO2/MWh for coalfired power plant and 0.326 tCO2/MWh for gas-fired power plant based on the survey on heatefficiency of power plant in the Philippines. The emission factor for diesel power plant iscalculated to be 0.533 tCO2/MWh based on a default heat efficiency 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 to a regional
grid or connected to a regional grid via an internal grid not connecting to a captive power2

generator (Case 1), the value of operating margin including LCMR resources, using the bestheat efficiency among currently operational plants in the Philippines in calculating emission
factors of fossil fuel power plants, are applied. The emission factors to be applied are set as“Emission factor for Case 1(tCO2/MWh)” in section I below.
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 (Case 2), the lower value
between emission factors of “Emission factor for Case 1 (tCO2/MWh) shown in Section I below
and the conservative emission factor of diesel-fired power plant of 0.533 tCO2/MWh is applied.
The emission factors to be applied are set as “Emission factor for Case2 (tCO2/MWh)” insection I below.
In the case that the solar PV system(s) in a proposed project activity is only connected to aninternal grid connecting to a captive power generator (Case 3), the emission factor of a dieselgenerator calculated by applying the most efficient heat efficiency of 49%, an efficiency level
which is above the value of the world’s leading diesel generator is applied, which is set as0.533 tCO2/MWh.
The emission factors for each case are shown in Section I.
