\[LF=\frac{P_{avg}}{P_{peak}}\]
Variables
LFload factor
Pavgaverage load demand (kW)
Ppeakpeak load demand (kW)
Description
What is this formula?
Load Factor measures how efficiently electrical demand is utilized over a period of time by comparing the average load to the peak load.
When to use it
Use this formula when evaluating electrical consumption patterns, utility demand charges, industrial energy efficiency, and power system utilization.
Example
A manufacturing plant has:
Average demand = 450 kW
Peak demand = 600 kW
Formula:
LF = Pavg / Ppeak
Substitution:
LF = 450 / 600
Result:
LF = 0.75
LF = 75%
