PF-adjusted demand calculator

Apply the tariff's reference-to-measured PF ratio to metered demand when the contract specifies this adjustment.

D_{\text{PF}} = \frac{D_{\text{meter}} \times \mathrm{PF}_{\text{base}}}{\mathrm{PF}_{\text{actual}}}

Calculator

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

Given

D_{\text{PF}} = \frac{320 \times 0.9}{0.8} = 360

Symbol	Meaning	Unit
$D_{\text{PF}}$	PF-adjusted demand	kW
$D_{\text{meter}}$	metered demand	kW
$\mathrm{PF}_{\text{base}}$	tariff reference power factor	ratio
$\mathrm{PF}_{\text{actual}}$	measured power factor	ratio

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