The Second Fuel column allows the user to specify a secondary resource fuel type to use for a resource. If this field is non-zero the model will use the fuel that has the lowest total cost, inclusive of emissions and fuel limits. Secondary fuel usage is standard output in the Resource Output table. If the secondary fuel type is being used, it will be reported here; if it is not used these columns will be blank in the Output.
NOTE: The ID column in the "Fuel" table is a unique (text) identifier. This field can contain both Alpha and Numeric characters. All references to the fuel ID must use the unique (text) identifier.
