Generation of electricity from run-of-river hydro power generation N/Asystem(s)F. Establishment and calculation of reference emissions
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 run-of-river hydro power generation system(s) in a proposed project activity isdirectly connected to a regional grid or connected to a regional grid via an internal grid notconnecting to a captive power generator (Case 1), the value of operating margin including
LCMR resources, using the best heat efficiency among currently operational plants in thePhilippines 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 case the run-of-river hydro power generation system(s) in a proposed project activity isconnected to an internal grid connecting to both a regional grid and a captive power generator(Case 2), the lower value between emission factors of “Emission factor for Case 13

JCM_PH_F_PM_ver01.0(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 Case 2 (tCO2/MWh)” in Section I. below.
In the case that the run-of-river hydro power generation system(s) in a proposed project activity
is only connected to an internal grid connecting to a captive power generator (Case 3), theemission factor of a diesel generator calculated by applying the most efficient heat efficiencyof 49%, an efficiency level which is above the value of the world’s leading diesel generator isapplied, which is set as 0.533 tCO2/MWh.
The emission factors for each case are shown in Section I.
