Generac Bi-Fuel™ generators use diesel as a pilot fuel to ignite the natural gas, eventually running primarily on natural gas, but they are also able to run on diesel fuel alone as conventional diesel generators typically operate. The natural gas provides extended running times not available on diesel-only generators. It also allows for reduced on-site diesel fuel storage, which means a smaller footprint and reduced diesel fuel maintenance.

Risk Mitigation via Fuel Redundancy 
Generac Bi-Fuel generators mitigate refueling issues by operating primarily on utility-supplied natural gas. That means less on-site diesel fuel is required and running times will be greatly extended compared to diesel-only solutions.

Lower Total Cost of Ownership 
Because natural gas costs less than diesel, fuel costs are significantly reduced over the long term. And since less on-site diesel fuel is required for long running times, installation, operational and maintenance costs are reduced.

Reduced Exhaust Emissions
Bi-fuel generators are cleaner and more environmentally friendly than diesel-only generators. They emit about 30% less nitrogen oxides and 50% less particulate matter than comparable diesel-only units.

Scalability as Part of a Modular Power System
Generac Bi-Fuel generators can be configured as part of a Modular Power System (MPS)—connected via integrated paralleling with other Generac generators. This makes the system scalable, meaning there is no need to install more power than you need.

Code Compliance 
Generac Bi-Fuel generators meet the on-site fuel requirements for emergency systems as referenced in NEC700 and NFPA 110. Less on-site diesel fuel means easier permitting. And indoor fuel installations with capacity limits per NFPA or local codes become a viable option.
