The script configuration screen:
And the actual line-item script:
Rem On-peak energy charge
EnergyUsageOnPeak = Total(ValueType.RealEnergyNet,
SeasonType.Winter, DayType.WorkingDay,
TimeOfUseType.EnergyOnPeakWinter) + _
Total(ValueType.RealEnergyNet, SeasonType.Summer,
DayType.WorkingDay, TimeOfUseType.EnergyOnPeakSummer)
Unit = GetUnit(ValueType.RealEnergyNet)
Quantity = EnergyUsageOnPeak
Charge = Quantity * RatePerUnit
If Charge = 0 then Visible = False
Sample Demand Charges Script
Demand charges may become fairly complex, as are the Generations System and
Transmission Demand charges in the sample tariff. The example addresses this tariff
requirement by using a number of rate schedule features:
 Global variables
 Times of Use
 Proration
Global Variables
The following Global Variables are used in the Demand calculations. Global variables
permit passing of results from one line item to other line items.
