Average interval demand calculator

Divide energy recorded in a demand interval by that interval in hours to obtain its mean power.

Units

D_{\text{interval}} = \frac{E_{\text{interval}}}{\Delta t}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

D_{\text{interval}} = \frac{72}{0.25} = 288

Symbol	Meaning	Unit
$D_{\text{interval}}$	mean demand over meter interval	kW
$E_{\text{interval}}$	energy during interval	kWh
$\Delta t$	interval duration	h

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
