Diesel Generator Sets

Cat® diesel generator sets, engineered for industrial, commercial, and mission-critical applications. deliver dependable standby and prime power where reliability is paramount. Our product range spans 6.8 to 5,720 ekW (6.8 to 7,150 kVA) in both 50 Hz and 60 Hz configurations, giving consultants and contractors precise flexibility during project design.

Each generator set is engineered for optimal efficiency and long-term durability, contributing to low operating costs and typically consuming less than 0.1 gallons (0.38 L) of diesel per kilowatt-hour. Systems are rigorously tested for stable output, rapid response during load changes, and consistent performance in demanding environments.

Cat diesel generator sets can last up to 15-30 years with lifespans of 20,000 to 30,000 operating hours. Whether supporting emergency backup for facilities or providing continuous power for ongoing operations, our commercial and industrial diesel generator sets help minimize integration complexity and deliver reliable power when it matters most.
