Table
Diesel Generator Fuel Use, L/h by kW Load
Diesel Generator Fuel Use, L/h by kW Load lookup table with assumptions and boundary notes.
Scope
Fuel estimate only. Actual generator fuel use depends on engine model, load factor, maintenance, temperature, fuel, and altitude.
Lookup table
Estimate diesel fuel consumption by electrical load using a conservative litres-per-kWh planning factor.
Scroll sideways to keep row labels aligned with hidden columns.

Notes
- Check table values for preliminary lookup and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
