Diesel-powered generator sets are the most used standby emergency power systems throughout the world.
These gensets are to be used only when power is lost from the utility or main grid. Once the normal power source is reestablished, power is once again supplied from the normal source and these standby generators shut down. Stationary engines are defined as permanently installed or located on site for a minimum period of 12 months.
Emergency standby power gensets are exempt from EPA emission standards for diesel generators. The EPA has ruled that Tier 2 and Tier 3 engine generators sufficiently reduce emissions and so don't require such gensets to comply with Tier 4 Interim and Tier 4 Final rules in the U.S.
Because regulations vary for emergency and non-emergency generator sets and required EPA emergency generator rules compliance also varies by the size and year of the generator set, it's a good idea to check if your generator is compliant with local and state regulations.
Emergency engines can operate for 100 hours per year for any combination of the following:
