Fuel & Energy — Site Generator Fuel
Site Generator Fuel for equipment fleet management.
Generators are chronically oversized and therefore chronically wet-stacked: a 100 kVA set loafing at 25% load carbons its cylinders and still burns half the fuel of proper loading. Sizing to 60–80% average load is both the fuel answer and the engine-health answer.

About Fuel & Energy — Site Generator Fuel
Fuel & Energy — Site Generator Fuel computes the governing relationship L = kVA×0.8×load% × SFC × h live as you type. Generators are chronically oversized and therefore chronically wet-stacked: a 100 kVA set loafing at 25% load carbons its cylinders and still burns half the fuel of proper loading. Sizing to 60–80% average load is both the fuel answer and the engine-health answer. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Fuel & Energy — Site Generator Fuel
- 1Enter your values — Generator size, Average load, Run hours/day, Specific consumption (sensible defaults are pre-filled).
- 2Read the live results: Daily fuel, Monthly (26 days).
- 3Check the "with your numbers" line to see L = kVA×0.8×load% × SFC × h substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
