Bi-Fuel Generators

Bi Fuel generator sets

Bi-Fuel generators combine the power of diesel fuel with the longevity of natural gas. They meet the NEC and NFPA code requirements for on-site fuel storage while providing the reliability of natural gas flow during a crisis or extreme weather event. Should natural gas not be available, bi-fuel generators can run on diesel fuel alone. By offering fully integrated solutions that are the only EPA-compliant bi-fuel generators available straight from the factory, Generac is able to provide dependable solutions with flexible fueling options to meet the needs of various backup power applications.

Generac Bi-Fuel Generators

Generac Bi-Fuel™ generators start on diesel fuel and add natural gas as load is applied, until the unit runs primarily on natural gas. Generac’s Bi-Fuel generators are fully integrated solutions, not after-market conversions in the field. That means every component is specifically designed, engineered, and factory validated to work together. Generac Bi-Fuel generators have the added benefit of being EPA compliant from the factory—the only bi-fuel systems on the market that can make such a claim.

Risk Mitigation via Fuel Redundancy

Despite the perceived reliability of on-site diesel fuel, power outages can damage infrastructure and make diesel refueling difficult or impossible. 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. And because the natural gas infrastructure tends not to be affected by the same conditions that lead to power outages, fuel reliability is improved.

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.

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.

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.
