Calculation path

Each load group creates daily kWh from watts and hours; thirty days creates monthly energy and coincidence estimates peak.

Calculation path

Daily kWh = sum(load watts x daily hours) / 1000; peak watts = connected watts x coincidence factor.

What you provide

What you provide

  • Continuous-group load: Combined watts for the first household load group.
  • Continuous-group hours: Average daily operating hours for the first group.
  • Intermittent-group load: Combined watts for appliances with a shorter schedule.
  • Intermittent-group hours: Average daily operating hours for the second group.
  • Coincident demand factor: Share of combined connected watts expected at the same time.
  • Electricity tariff: Price paid for one kilowatt-hour of electricity.

Choose the maximum decimal places shown. This does not increase source accuracy.

This two-group profile is for planning, not service sizing; motor surge, phases, power factor, diversity, tariffs, and code loads differ.

This is an educational planning result, not a structural, electrical, thermal, solar, battery, generator, or safety design. Confirm specifications, units, codes, and professional requirements before acting.
