8/8/2019 Grid Emmession Factor

1/37

BASELINE METHODOLOGY PROCEDURE:

STEP 1: Identify the relevant electric power system

STEP 2: Select an operating margin (OM) method

STEP 3: Calculate the operating margin emission factor according to the selected method

STEP 4: Identify the cohort of power units to be included in the build margin (BM)

STEP 5: Calculate the build margin emission factor

STEP 6: Calculate the combined margin (CM) emission factor
