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).

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 Mexican grid. The emission
factor is calculated based on the latest electricity mix in Mexico and refers to the conservativeemission 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 0.742 tCO2/MWh for coal-fired
power plant and 0.343 tCO2/MWh for gas-fired power plant based on the survey on heatefficiency of power plant in Mexico. The emission factor for diesel power plant is calculated tobe 0.533 tCO2/MWh based on a default heat efficiency of 49%, an efficiency level which isabove 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 a captive power generator, to a grid (PV Case 1), the value ofoperating margin without low cost/must run (LCMR) resources, using the best heat efficiency
among currently operational plants in Mexico in calculating emission factors of fossil fuelpower plants, are applied.
In the case the PV system(s) in a proposed project activity is connected to an internal gridconnecting to both a grid and a captive power generator (PV Case 2), the lower value between
the emission factor for PV Case 1 (tCO2/MWh) shown in Section I. and the conservativeJCM_MX_AM001_ver01.0

emission factor of diesel-fired power plant of 0.533 tCO2/MWh is applied. The emission factors
to be applied for PV Case 2 (tCO2/MWh) are shown in Section I.
In the case that the PV system(s) in a proposed project activity is only connected to an internal
grid connecting to a captive power generator (PV Case 3), the emission factor of a diesel
generator calculated by applying the most efficient heat efficiency of 49%, an efficiency level
which has not been achieved yet by the world’s leading diesel generator is applied: 0.533
tCO2/MWh.
The reference emission factors for each case is shown in Section I.
