A 80 kVA generator delivers approximately 64 kW of usable power — enough to run a large office or hotel with lifts, kitchens and central plant on diversity. At 75% load it consumes roughly 14.5 litres of diesel per hour. In South Africa a 80 kVA silent diesel generator typically costs between R165 000 and R215 000 excluding VAT and installation.

Eighty kVA covers large offices and hotels when diversity is real. If the largest motor exceeds ~22 kW, review 100 kVA so starting current does not collapse voltage.

Silent 80 kVA three-phase diesels typically cost R165,000 to R215,000 excl. VAT.
About 14.5 L/h at 75% load — roughly R341/h at R23.50/L.
Around 64 kW: large offices, hotels and comparable mixed commercial loads including lifts on diversity.
Three-phase 400 V is standard.
Structural pad or roof engineering where applicable, fuel, AMF, exhaust, earthing and full CoC installation.
100 kVA adds headroom for motor starting and growth. If your calculated peak is already near 64 kW, step up rather than run flat-out.
