Times of Use
The Demand scripts use the Demand Times of Use definitions.
Line Items
 Generation System Demand Calcs
The first line item calculates the various peak demand values listed in the rate tariff.
The results of the calculations in this line item are assigned to Global variables.
rem Intermediate calculations for Generator System Demand and
Transmission Demand
Dim TestQty As Double
rem calculate larger of AM and PM Winter peak demand
