Your peak demand is the point during your monthly billing cycle when you use the most energy. It's the highest spike in your energy use. Your peak changes from month to month depending on how you use your energy.
The option looks at your highest peak demand during on-peak hours. You will see a demand charge and an energy charge on your bill. Demand charge is the peak demand multiplied by the demand rate. The energy charge is the kilowatt-hours (kWh) used during the billing month multiplied by the rate per kWh. If you can shift usage to off-peak hours, your average cost may be lower.
