How is the Time of Use (TOU) schedule used?
A Time of Use (TOU) schedule is used to specify time periods for determining energy usage and demand for
different time-of-day, day of the week, and seasons. Typically, the cost of energy usage and demand are higher
during the day than night. Therefore, the need to separate the usage and demand between various time periods is
needed in order to apply the corresponding rates.
The TOU schedule can be setup to incorporate seasons, (up to 4 seasons per year) with a defined start and end date.
The illustration below displays the TOU schedule setup screen.
When incorporating the start and end date, the “End date” or “Start Date” cannot
overlap or have gap. All the seasons time periods should cover one whole year.
Figure 12.1 - TOU Schedule
In this example, the TOU shows each season (Season1 and Season2) and each TOU types (On-Peak, Off-Peak, and
Mid-Peak) are listed on individual tabs and displays the “time allocation” grid as Monday through Sunday-Holiday
with a From and To time entry. Each schedule is broken down into a 24-hour day and 30-minute intervals from
00:00 to 24:00. The illustration below shows Season1, On-Peak time, and day table schedule.
