A 150 kVA generator delivers approximately 120 kW of usable power — enough to run a large supermarket or medium factory with process plant and HVAC. At 75% load it consumes roughly 26.5 litres of diesel per hour. In South Africa a 150 kVA silent diesel generator typically costs between R255 000 and R330 000 excluding VAT and installation.

Is 150 kVA the right size?
One-fifty kVA is the step-up when 100 kVA is tight on motor starting. Factories should still provide a motor list — large DOL compressors may need 200 kVA.
150 kVA generator FAQs
Silent 150 kVA three-phase diesels typically range from R255,000 to R330,000 excl. VAT.
About 26.5 L/h at 75% load (~R623/h at R23.50/L).
Around 120 kW — large supermarkets, medium factories and hospital blocks with substantial HVAC.
Three-phase 400 V only in standard commercial supply.
Engineered foundation, acoustic and exhaust design, bulk fuel options, AMF paralleling readiness if required, and CoC installation.
Yes for many mid-size UPS loads, but IT rooms need clean transfer, correct grounding and often N+1 — engineer the topology, do not guess from kVA alone.
