As a result of providing the power of diesel with the many environmental benefits of natural gas, Generac has seen an increase in the interest and installation of its Bi-Fuel™* generators, largely due to their many advantages:
- Extended run times
- Environmentally friendly
- Enhanced reliability
- Ability to provide factory-tested and warranted units
- Scalability as part of a Generac Modular Power System (MPS)
Bi-fuel generators provide end-users with the advantages of using both diesel and natural gas fuels while minimizing the disadvantages. Diesel fuel is used to start the engine and, as load is applied, the transition is made to a blend of diesel and natural gas. The diesel fuel remains necessary to maintain ignition of the natural gas, but in bi-fuel mode diesel consumption is only a small percentage of full diesel operation. Utility-supplied natural gas provides extended run times, which can be a significant benefit during major storms or other events where diesel fuel deliveries can be compromised.
“The standard diesel governing system runs continuously; during sudden load changes, diesel instantly becomes the dominant fuel so the system reacts just like a typical diesel generator,” explained Mark Sweeney, Business Manager-North Central, Generac Industrial Power.
Bi-fuel generators also have lower diesel fuel management costs. With the EPA’s new regulations aimed at reducing emissions from diesel engines, the use of ultra-low sulfur diesel (ULSD) in mandated in all standby generator applications. ULSD goes through additional refining processes which makes it less stable than traditional diesel fuel. This requires the fuel to be polished more frequently to ensure the fuel does not degrade and/or clog the engine filters. With bi-fuel generators, less diesel fuel has to be stored on-site, resulting in lower costs.
At the same time, because on-site diesel fuel is still part of the system, reliability is improved. Should the natural gas supply be interrupted, the generator can run on 100% diesel fuel. The system will automatically and seamlessly switch to 100% diesel operation with no loss of power during the transition.
Generac Bi-Fuel™ generators meet the on-site fuel requirements for emergency systems as referenced in National Electric Code 700 and National Fire Prevention Association (NFPA) 110. Less on-site diesel fuel typically means easier permitting, and indoor fuel installations with capacity limits per NFPA or local codes become a viable option.
“Generac is the only manufacturer supplying bi-fuel standby generators directly from the factory, providing the key advantages of factory testing and a factory warranty,” said Sweeney. “Other manufacturers have to convert their generators to bi-fuel by adding third-party after-market equipment which can lead to problems. There is also the question of responsibility should something malfunction on the generator,” he added.
The market has shown significant interest toward products that burn inherently clean natural gas as an alternative to diesel solutions. Bi-fuel generators utilize up to 75% clean burning natural gas providing the market with another viable fuel option.
Finally, Bi-Fuel™ generators can be used as part of Generac’s innovative MPS. While it is well-known Generac’s MPS provides redundancy, flexibility and scalability in a modular type paralleling system, MPS also provides the ability to mix and match gensets.
