Diesel generator can run for long hours continuously as a power supply source and also as a standby or during emergency power needs.
They require less maintenance due to their durability, reliability and the sturdiness characteristic and also they are considered cheaper to operate due to the low fuels costs as compared to the other types of fuels such as gasoline and propane.
They can withstand heavy load for long hours and start off the power supply on full load within minutes and must be regularly maintained to ensure they provide quality power throughout their service life. The best generator maintenance practice is following the maintenance schedule provided by the manufacturer of the generator to ensure maximum service time for the generator and proper operation when it is called upon to provide power.
Having a well-designed and well-maintained standby power system is the best protection against utility power outages. For hospitals and other health-care facilities they can be life-threatening. For businesses like data centers, the outages can be enormously costly. Other critical facilities at risk include government offices, police departments, fire stations, airports, and water/sewage treatment plants.
