Residential Electricity Demand Charges
The demand charge is a part of your bill that shows the highest energy usage on a given period of time, usually at 15 – 30 min intervals. This is also called peak demand. On the other hand, the energy charge is your overall electricity usage during a billing cycle. You can lessen your electricity bill by reducing the peak demand.
