Table
Diesel Generator Fuel Use, L/h by kW Load
Diesel Generator Fuel Use, L/h by kW Load reference with assumptions and boundary notes.
Reference boundary
Fuel estimate only. Actual generator fuel use depends on engine model, load factor, maintenance, temperature, fuel, and altitude.
Reference table
Estimate diesel fuel consumption by electrical load using a conservative litres-per-kWh planning factor.
| Electrical load (kW) | 0.25 L/kWh | 0.30 L/kWh | Use |
|---|---|---|---|
| 10 | 2.5 | 3 | Preliminary runtime and fuel-storage conversation |
| 25 | 6.3 | 7.5 | Preliminary runtime and fuel-storage conversation |
| 50 | 12.5 | 15 | Preliminary runtime and fuel-storage conversation |
| 100 | 25 | 30 | Preliminary runtime and fuel-storage conversation |
| 250 | 62.5 | 75 | Preliminary runtime and fuel-storage conversation |
| 500 | 125 | 150 | Preliminary runtime and fuel-storage conversation |
| 1000 | 250 | 300 | Preliminary runtime and fuel-storage conversation |
Use notes
- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
