Gas G-Drives provides a wide range of spark ignited natural gas engines in both the Gas Series and Gas Low Emissions Series. These diverse engines are offered from 47 to 138kWe Continuous at 50 Hz and 44 to 861kWe Standby/Prime/Continuous Power at 60Hz. From the small and durable G5.9 to the large and transient capable GTA50, we supply the superior gas solution to meet your power generation needs.

Our Gas G-Drive engines suited for continuous applications deliver extreme durability, long life, and dependability, while our standby application engines supply unmatched transient capability through the ability to pick up block load while meeting NFPA 110 requirements.

Select Gas G-Drive products, from 434 to 554 kWe Prime Power at 50 Hz and 521 to 665 kWe Prime Power at 60 Hz, provide reliable power for locations with unstable grids for limited time prime power. Capable of running on pipeline natural gas, select Gas G-Drive models also provide the option to run on propane as an emergency fuel
