Use this optional column to activate the blended fuel capability and enforce a percentage of secondary fuel to burn in relation to the overall plant fuel usage. The logic is based on fuel usage, not MWh. Both the Second Fuel Min Ratio and Second Fuel Max Ratio columns are used to set the min/max limits.

Valid entries for both columns are between 0 and 1, with NULL/blank for the Second Fuel Min Ratio defaulting to 0 and NULL/blank for the Second Fuel Max Ratio defaulting to 1.

Together, these columns put lower and upper bounds on the ratio of [Secondary_Fuel_Usage]/[Fuel_Usage] for each hour (or sub-hour) being dispatched.

 NOTE: Specify inputs for any time period (annually, monthly, weekly, hourly, or sub-hourly). For information on specifying a variable's time series, see Entering a Time Series.
