Standby Generator Fuel Options

Diesel fuel is the traditional choice for commercial and industrial standby power. But it is by no means the only choice. Generac offers generators powered by a variety of fuel types to meet virtually any application or regulatory requirement.

Enjoy Long Running Times Without Refueling

In the past, gaseous fuels had been avoided in industrial backup power applications based upon cost effectiveness, power density, and perceptions of durability and fuel reliability. That is no longer the case.

  • Cost-effective Engines: Automotive-style spark-ignited engines are more readily available in high volumes, making them more cost-effective components to source than similarly sized diesel engines.
  • Long Running Times: A key benefit to natural gas fuel is long running time. Because natural gas is supplied by a utility, refueling is not an issue.
  • Environmentally Friendly: Not only do natural gas-fueled engines emit fewer nitrogen oxides and particulate matter than comparable diesel-fueled engines, but they avoid the fuel containment, spillage, and environmental concerns associated with storing diesel fuel.

The Traditional Choice for Standby Power

Diesel-fueled generators are an efficient choice for high kW applications, as well as for facilities where code requirements call for on-site fuel storage, like hospitals and 911 call centers. They can also provide backup power in remote areas that do not have access to a natural gas infrastructure. To provide the best possible diesel-fueled standby power solutions, Generac identifies and pre-qualifies diesel engines proven in real-world applications under adverse conditions. Then we work hand-in-hand with best-in-class diesel engine manufacturers to optimize designs specifically to meet Generac requirements.

The Only True Bi-Fuel Solution—EPA Compliant 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. It’s not a new concept, but Generac’s Bi-Fuel generators aren’t after-market conversions in the field, unlike practically every other bi-fuel solution on the market. They are fully integrated solutions. That means every fuel train component, every sensor, every actuator on the engine is specifically designed, engineered, and factory tested to work together. Optimally. Efficiently. And backed by a full Generac factory warranty and product support.

This gives Generac Bi-Fuel generators the added benefit of being EPA compliant from the factory—the only bi-fuel systems on the market that can make such a claim.
