F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emission is calculated by multiplying transmission loss in the reference scenario(LOSSRF,L) by the emission factor of the grid (EFGrid,y).
F.2. Calculation of reference emissions
Reference emission is calculated by the following equation.

RE y = å (LOSSRF,L,y ´ EFGrid,y )(1)

L

LOSSRF,L, y = LOSSPJ,L, y ´
