Cummins Power Generation's entire stationary diesel generator set range from 680-2,750 kW has received Environmental Protection Agency (EPA) Tier 4 interim (Tier 4i) certification for the North American market. EPA mandates that all non-emergency generator applications be Tier4i certified. Nonetheless, in certain locations, the local ordinances may require that emergency backup generators also adhere to stricter emissions limits. Because Cummins' stationary diesel generator sets can be configured to meet requirements beyond Tier 4i if necessary, the generator sets are available to comply with the most stringent emissions regulations.
