Load factor is a simple ratio with a big impact. It tells you — and your suppliers — how efficiently you use the capacity you draw. A better load factor can mean better pricing and lower demand-related costs.
What load factor is
Load factor is the ratio of your average demand to your peak demand over a period, expressed as a percentage. A high load factor means your usage is steady and predictable; a low load factor means you have sharp peaks relative to your average consumption.
Simplified: Load Factor = (total kWh used) ÷ (peak kW × hours in the period). Higher is generally better.
Why it matters
Suppliers and utilities prefer steady, high-load-factor accounts because they're cheaper and less risky to serve — the infrastructure serving your peak is used more of the time. That efficiency often translates into more favorable pricing and lower demand charges relative to your energy use.
How to improve load factor
- Flatten peaks by staggering equipment and managing HVAC.
- Shift flexible loads into otherwise low-usage hours.
- Use storage to smooth the profile the grid sees.
Improving load factor is really about reducing peaks and/or filling in valleys so your consumption is more even over time.
A quick example
A facility that runs steadily around the clock will have a high load factor and be attractive to serve. A facility that sits idle most of the day but spikes hard for a few hours has a low load factor — and will likely see higher demand charges and less favorable pricing, even at similar total consumption.
