For businesses assessing industrial backup power, the important questions extend beyond capacity: what condition is the generator in, does it suit the site’s electrical load, and what will installation cost?

How to Calculate Daily Diesel Costs
Once consumption has been established:
Daily fuel use = litres per hour × operating hours
Daily fuel cost = daily litres × diesel price per litre
For illustration only, suppose a test records 90 litres per hour at your intended load. Running for eight hours would consume:
90 × 8 = 720 litres per day.
At an illustrative diesel price of KSh 180 per litre, the daily fuel cost would be:
720 × 180 = KSh 129,600.

How Much Diesel Does a 625 kVA Generator Consume?
A 625 kVA generator does not consume a fixed amount of diesel every hour. Consumption depends on the electrical load, engine specification, operating condition and installation environment.
For the PAOU 500GF advertised at 500 kW / 625 kVA, the supplied information does not include a manufacturer fuel-consumption chart. An exact litres-per-hour figure therefore needs confirmation from the correct technical documentation or a supervised test.
Why the Operating Load Matters
A generator powering a small portion of its rated capacity will generally consume less fuel per hour than one carrying a heavier load. However, consumption does not necessarily increase in a straight line: 50% load should not automatically be assumed to use half the full-load fuel.

Is This a Silent Diesel Generator?
No—the advertised unit is open type and has no acoustic canopy. It should not be described as a silent diesel generator.
Before installation, have a qualified installer assess the site’s space, ventilation, exhaust routing, weather protection and noise-management requirements. Any proposed enclosure must suit the equipment and preserve the airflow and maintenance access it needs.
