Lower the peak at a hotel.
What Sets the Peak
A hotel runs around the clock. Its peak forms where cooling, the kitchen and the laundry overlap, and when that happens depends on occupancy, the season and the kitchen's hours.
In this example the peak is set at 4:45 pm on a Friday. Your own 15-minute record shows which interval sets yours.

How We Bring the Peak Down
- 01Read 12 months of interval dataYour utility's 15-minute demand for the last year, with the weather for the same period. The interval that set each month's charge is marked, and so are the days close behind it.
- 02Log the key circuitsCurrent loggers on the circuits that feed the largest loads, for 4 to 8 weeks in the season the peak falls in. Each load's share of every peak interval is measured.
- 03Design within each load's limitsEach load's limits are recorded before anything is designed. The design is simulated on your measured year before anything changes on site.
- 04Run the control and meter the resultA licensed electrician fits the controller and any relays or drives. The control runs on site, and each month's peak is metered on the panel.

Worked example: a 200-room hotel with a restaurant. Your own peak is read from your utility's 15-minute record.
