Dependable 

  • All components of our QSV91G series are designed, manufactured and integrated by Cummins for supreme performance and flexibility. Our generator sets combine low emissions, best-in-class load acceptance and efficiency to satisfy all your operational and environmental requirements.

Electrical Efficiency

  • Supplying electrical efficiency of up to 41% and NOx exhaust emissions as low as 0.5g/hp-h (250mg/Nm3), the QSV91G series offer the possibility of 90%+ energy efficient solutions in combined heat and power applications with minimal environmental impact.

Reliable Power

  • With up to 45% G1 ISO 8528 load step at 2000kWe, our advanced engine technology means that Cummins generator sets offer industry leading performance of load pickup transient capability. This ensures fewer voltage and frequency disturbances and faster recovery times, thus providing a rigid power supply for your requirements.
  • With 100% rejection load, our QSV91G series incorporate a range of turbocharger configurations tailored to your needs. Our generator sets with multi turbochargers are optimized for transient stability and handle large load swings quickly and effectively.

Fuel Flexibility 

  • Whether you use pipeline natural gas or other alternative gaseous fuels such as oilfield gas or biogas from landfills, the QSV91G series offer the ultimate flexibility. With power ratings of 1540kWe to 2000kWe, these 50 Hz and 60 Hz generator sets power a broad range of applications, from prime power in remote locations to standby, utility peaking, cogeneration and more. 
  • The QSV91G series operate on low-quality gases with lower BTU or energy content properties and varying methane numbers including flare gases from on-shore and off-shore oil and gas locations.

Cost Efficient

  • QSV91G series generator sets provide you with reduced maintenance costs per kWh, together with an outstanding worldwide responsive support network to maximize your value and economy. This results in lower total cost of ownership, providing predictive operating costs, long-term savings and faster payback on your investment.
  • With our established network of 600 distributors and 6,000 service and sales centers, we are ready to provide you with technical expertise and reliable assistance to keep your power up and running, anywhere in the world.
