You can make the Plant Optimizer aware that plant operations are suspended in the future with the Plant Disable Schedule feature. This marks a defined period of time as a period where the normal schedule does not apply. The yearly schedule and the daily schedule are the two options, which you can use to add a plant disable schedule. The yearly schedule is used for defining seasonal periods where either the plant is off or during periods where a daily shutdown schedule applies. This functionality is available at daily, weekly, and monthly levels. In the upper-right corner of the page, a message displays if the Coil Status is active for any of the associated coils. You can click the Information icon for more information. Load coils may have Coil Status mapped to a subplant that could override the schedules that show in the yearly or daily schedule.
