Understanding Load Factor
How we calculate. Load factor % = average demand ÷ peak demand × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Load Factor case uses average load 6.5 and peak load 10. Enter the same figures below to reproduce the worked path.
What is Load Factor?
A demand-shape KPI for buildings, campuses, and utilities. Distinct from logistics fleet load factor (payload/cube fill).
- Same UOM for average and peak
- Higher usually means flatter load
- Period must match the peak definition
The Formula
Worked Example
Common Use Cases
- Demand charges: peak vs average
- Facility energy: load shape
- Utility planning: system load factor
Pro Tips
- Align average with the same interval as peak
- Watch weather-driven peaks
- Pair with peak-to-average ratio
Limitations: Load Factor results are educational energy and utilities planning aids—not engineering, grid-operations, or investment advice. Confirm definitions with your ISO/RTO, plant, and regulatory reporting standards.
FAQ
Same as fleet load factor?
No—that logistics tool is cargo capacity fill. This page is electrical average÷peak demand.
What if peak load is 0?
Load factor is undefined—enter a positive peak load.
