DG Set Sizing Calculator
Estimate the diesel generator rating (kVA) your building needs from its connected load, demand factor and backup scope. Adjust the inputs for an instant figure — then get an engineered electrical design from our team.
Your load
Estimates running load = connected load × demand factor, then adds margin and converts to kVA at your power factor. Motor starting / harmonic loads may need a larger set.

Thanks! Our electrical team will send your tailored DG & power design within one business day.
Indicative estimates only — not a binding design. Actual DG rating depends on the detailed load schedule, motor starting, harmonics, altitude and ambient derating.
