Second Accounting Fuel Column
Column Type = Text
The Second Accounting Fuel column specifies a reference pointing to the ID Column in the Emission Rate Table. When populated, this accounting emission rate will be used in post-processing for emission rates/costs.
Like the Second Accounting Fuel column, the resource dispatch is done using the standard Primary and Secondary emission rates. Then, based on the emission rates/costs for the primary/secondary fuel, the model will calculate the total cost for the resource using the Accounting Emission Rate/secondary accounting emission rate (if these are defined). The Total_Emission_Cost in the Resource output will be populated with the accounting emission costs (when applicable).
Zonal prices and dispatch results are not affected by the use of the accounting emission rate columns - only the post-processing is adjusted. If accounting emission rates are used, those emission costs will also flow through to the Portfolio logic when applicable.
NOTE: If the Accounting Fuel's Price resolves to zero (0), the Accounting Fuel will not be used for the hour.
