Electrical Load Factor Calculator

How Electrical Load Factor works

The arithmetic follows load factor = average ÷ peak × 100. Electrical Load Factor uses Average demand, Peak demand to report Load factor.

With the loaded values, load factor evaluates to 52.50%. A second case makes the effect of one changed measurement visible.

Inputs for Electrical Load Factor

Average demand and Peak demand belong to Electrical Load Factor. Keep source units with average demand.

Loaded numbers demonstrate the calculation; they are not equipment recommendations. Replace them with values from the case being evaluated.

Average demand

Example entry: 42 kW.

Peak demand

Example entry: 80 kW.

Reading the Electrical Load Factor result

This output represents Electrical Load Factor.

The result informs selection but does not approve a component or installation.

Measurement and units

Keep tariff periods, demand intervals, meter ratios, and measurement bandwidth consistent with the question being answered. Check prefixes on average demand.

Matching units and measurement locations prevent false differences. Primary current can be checked in Current Transformer Reading Calculator.

Limits of this calculation

Average and peak must cover the same interval. Use Electrical Power Cost Calculator to a separate operating cost calculation.

The result reflects the formula scope, not every connected component. Unentered effects remain outside Electrical Load Factor. For fuel use, use Generator Fuel Consumption Calculator.

A useful Electrical Load Factor comparison

Record load factor before testing a different average demand value.

Document the alternate average demand source.
