Electricity Usage and Measurement
Electrical Diversity Factor Calculator
Electrical Diversity Factor helps you find diversity factor from sum of individual peaks and system coincident peak. The page keeps the arithmetic visible so you can check the result against the original measurements.
Inputs for this calculation
Use measurements from one operating condition.
From inputs to result
This page evaluates diversity = individual peaks ÷ system peak. Its variables correspond to Sum of individual peaks and System coincident peak.
Using the loaded examples gives 1.39. Your saved case should identify where each entry came from.
Calculate diversity factor from sum of individual peaks and system coincident peak. Continue with Electrical Coincidence Factor Calculator to evaluate coincidence factor.
Preparing the calculation
Use tariff periods, demand intervals, meter ratios, and operating hours from the same billing case. Nameplate and meter values are not interchangeable unless they describe the same condition.
A denominator entry cannot be zero. Confirm decimal placement whenever a source uses a different unit scale. The specific power step is handled by Battery Specific Power Calculator.
- Sum of individual peaks
- Default example: 250 kW. Enter sum of individual peaks in kW.
- System coincident peak
- Default example: 180 kW. Enter system coincident peak in kW.
Input quality checks
An unlabeled assumption can make an otherwise correct result unusable.
Recheck decimal placement and unit conversion when the answer looks unusual.
Assumptions and limitations
Document the observation periods.
The surrounding system may introduce fixed charges, demand ratchets, seasonal rates, uncertainty, and future load change. Resolve material omissions before selecting a standard size or rating.
Use tariff periods, demand intervals, meter ratios, and operating hours from the same billing case.
A second scenario
Change Sum of individual peaks from 250 kW to 300 kW without altering the remaining fields. The calculated value shifts from 1.39 to 1.67.
The comparison demonstrates sensitivity, not a guaranteed field response.
Using this result in a larger analysis
Check the source of sum of individual peaks before calculating. A credible result requires every field to describe the same physical condition and unit basis.
After calculating diversity factor, compare its magnitude with billing rules, meter data, demand intervals, and operating schedules. An independent order-of-magnitude check can reveal a misplaced decimal or unit prefix.
If uncertainty remains, calculate labeled low and high cases. Include meter accuracy, sampling interval, waveform bandwidth, and conversion loss when those effects can change the decision.
Questions about Electrical Diversity Factor
What is the cleanest way to test another scenario?
Keep unaffected entries fixed so the cause of the difference remains visible. Use tariff periods, demand intervals, meter ratios, and operating hours from the same billing case.
