Bi-Fuel™

Genset Services

As the only true bi-fuel system, Generac’s Bi-Fuel™ generators are EPA-certified from the factory, tested and installed. All other bi-fuel systems are aftermarket systems that are retrofitted in the field. The Generac Bi-Fuel system components are specifically engineered to integrate together, with full factory warranty and service support included.

Consider the Features and Benefits of Bi-Fuel™:

  • Reduced Fuel Storage:
    Because natural gas is the principal fuel, smaller diesel tanks are viable. Less fuel stored on site can lead to easier permitting and lower fuel maintenance costs. In addition, indoor fuel installations with capacity limits, per NFPA or local codes, may become feasible.
  • On-Site Fuel:
    For some applications, on-site fuel is required, or strongly preferred. With Bi-Fuel, if there is ever a problem with the natural gas supply, the generator automatically switches to 100% on-site fuel, without affecting operation. This meets the on-site fuel requirements for emergency systems, as referenced in NEC700 and NFPA110.
  • Lower Cost:
    The cost of a midrange, natural gas generator is approximately twice that of a comparable diesel unit. Bi-Fuel offers the many benefits of natural gas for only slightly more than a diesel-powered system and has a higher thermal efficiency than natural gas solutions. This may translate into operational fuel savings based on traditional fuel costs.
  • Reduced Exhaust Emissions:
    Bi-Fuel generators emit about 30% less nitrogen oxides and 50% less particulate matter than comparable diesel-only units, for an environmental solution.
