I am creating a TimeOfDaySchedule for NewYork with summer demand rates defined in three blocks

8AM to 6PM -$8/kW 8AM to 10 PM -$15/kW All other hours of all days- $16/kW Ref- ConEd NewYork, General Large Rate-II

I know that in defining the schedule we assign intervals with the 1 for peak, 3 for off-peak and I can use 2 for the mid peak. But how to take care of the time common to peak and shoulder period both (1 or 2)?

For that you can use the native variable called PeakAndShoulderEnergy and PeakAndShoulderDemand which can be used in the UtilityCost:Charge:Simple and UtilityCost:Charge:Block field called Source Variable. To see all the variables automatically created by EnergyPlus for tariff calculations, see the Native Variables table in each Tariff Report in the HTML file.

Thanks, @JasonGlazer, I am aware of the tariff report variables are populated based on TimeofUse period defined in TimeofDaySchedule (Using 0,1,2,3). What my question is how to define the interval common to peak and shoulder intervals, as I can not assign '1' and '2' both for 8 am - 6 pm in schedule definition. If I assign the '1' for 8 am - 6 pm and '2' for 6 pm - 10 pm, the demand will be calculated for should peak from the half hour max demand between 6pm-10 pm @15/kW while it should be calculated for half hour max demand between 8am-10pm.
