The Complete List of Generator Fuel Types

In addition to natural gas and diesel, primary generator fuel types include bi-fuel and even propane. Understanding the pros and cons of each fuel type is crucial when deciding what type of generator to purchase for your facility.

Generator Fuel Types: Pros & Cons

The various generator fuel types have unique pros and cons to consider when trying to determine the best type of generator for your needs. These pros and cons include:

  • Diesel: Diesel is one of the most common generator fuel types for standby applications. Known for reliability, diesel-fueled generators run on fuel that is readily available and easy to store onsite at your facility. Diesel generators are great as backup for mission-critical functions since they have a very fast kick-in time. Downsides of diesel include it having a higher level of emissions than other options, which may cause issues for passing EPA standards. Another downside is that diesel doesn’t store well over long periods of time, so further steps may need to be taken to ensure stored fuel is ready for use.
  • Natural Gas: Natural gas burns cleaner than diesel, resulting in lowered levels of emissions. Generators fueled by natural gas can also be less expensive than their diesel counterparts. Disadvantages to choosing natural gas include the inability to store fuel onsite, as well as delayed start times when these generators are needed to provide power, which can cause temporary interruptions in operations.
  • Bi-Fuel: Combining features of diesel and natural gas generators, units that run on bi-fuel offer flexibility. Bi-fuel generators may be convenient for meeting EPA standards as they have lower emissions than standard generators. However, bi-fuel units are not a standard unit type and not all major manufacturers produce this type of generator.
  • Propane: Generators fueled by propane are ideal for remote sites where other types of fuel may not be readily available. Propane generators are typically smaller than other types, and larger sized units can become quite costly.

When trying to determine the best generator fuel type for your needs, consider factors like fuel availability and storage. It can also be helpful to think about what size generator you need, as this may narrow down your fuel options, as well as manufacturer preferences.
