When this guide fits

The electric bill shows demand, kW demand, peak demand, capacity, or a charge based on the highest usage interval.

Demand charges are based on peak power, not total kWh alone. Running several high-load appliances at the same time can create a charge even if monthly kWh looks reasonable.

Check first

  • Find demand, kW, peak demand, or capacity charge lines.
  • Check the time window or interval used to set peak demand.
  • Look for EV charging, HVAC, dryer, oven, pool pump, or water heater overlap.
  • Compare the demand charge with energy and delivery charges.

Practical savings moves

  • Avoid stacking flexible high-load appliances during the same peak window.
  • Shift EV charging, laundry, or pool pump runtime where practical.
  • Use demand-charge math before changing total kWh habits.
  • Review whether the rate plan still fits your household pattern.

Avoid these mistakes

  • Do not compare demand-charge bills by monthly kWh only.
  • Do not turn off essential heating, cooling, or safety equipment just to avoid a peak.
  • Do not ignore fixed fees that remain after reducing peak demand.

FAQ

Short answers for search visitors and bill-checking moments.

What causes a residential demand charge?

A demand charge can be triggered by the highest peak kW interval, often when several high-load appliances run at the same time.

Is demand charge the same as kWh usage?

No. kWh measures total energy over time, while demand usually measures peak power during a shorter interval.
