WPI offers BI-FUEL™ generators that combine diesel fuel’s power with natural gas’s longevity. 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 weather event. If natural gas is unavailable, the generator can run on diesel fuel. Generac BI-FUEL™ generators are the only EPA-compliant generators straight from the factory.

• Generac Bi-Fuel generators start on diesel fuel and add natural gas as load is applied until the unit runs primarily on natural gas.
• Unlike other bi-fuel solutions, Generac BI-FUEL™ generators are fully integrated, meaning every fuel train component, sensor, and the actuator is specifically designed, engineered, and factory-tested to work together.
• Generac Bi-Fuel generators have the added benefit of being EPA compliant from the factory – the only bi-fuel system on the market to make such a claim.
• These units can also be paralleled together for redundancy and to configure larger kW nodes. This can be accomplished with Generac's onboard self-paralleling control platform.
