Bi-Fuel Generators

Generac Bi-Fuel™ generators meet the on-site fuel requirements for emergency systems as referenced in NEC700 and NFPA 110, and they are the only EPA compliant engine right from the factory. Since less diesel is used, they have fewer emissions and a smaller carbon footprint compared to diesel only.

600kW Bi-Fuel Generator
This disruptive technology starts with a strong 18.13L diesel engine that transitions to gaseous fuel as load is applied, providing 600 kW.
500kW Bi-Fuel Generator
The best of both worlds, strong 15.2L diesel engine starting power combined with the longevity of gaseous fuel for extended run times.

Description

A bi-fuel generator uses two types of fuel, but the fuels are not mixed together during operation. The engine is capable of switching between the two so that it is always using the type of fuel most efficient for the conditions at hand.
