Generation of electricity from solar PV system(s)N/AF. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Considering that Palauan grids are not connected to other grids and use diesel fuel as a powersource, net emission reductions are ensured as follows.
It is assumed that solar PV systems installed in Palau will replace grid electricity and/or captive
electricity generated by the existing diesel generators whose power generation efficiency isestimated to be around 33-41%, which leads to the CO2 emission factor of 0.805-0.631
tCO2/MWh.
However, applying such emission factor derived from the existing diesel generators does notachieve net emission reductions. Therefore, the power generation efficiency of 49%, which has
not been achieved yet by the world’s leading diesel generators, is employed in this methodology
to ensure net emission reductions. The emission factor of grid and captive electricity is set to0.533 tCO2/MWh based on the power generation efficiency of 49%.
