About HIPOWER Systems

HIPOWER Systems (a Yanmar company and division of Himoinsa, S.L.) is the principal supplier of power-distribution equipment and prime, standalone power-generation equipment and packages to the U.S. and Canadian markets, serving the residential, commercial and Industrial sectors including the agriculture, telecommunications, healthcare and oil & gas industries. The company builds and customizes diesel generators from 8 kw to 3 MW and natural gas or alternative fuel/bi-fuel sets from 20 to 400 kW with a complete range of accessories, including automatic transfer switches, paralleling switch-gear, UL tanks, enclosures and power distribution equipment.

In North America and throughout the globe, HIPOWER’s rental packages and power distribution equipment are recognized as the best power solution source for emergency and disaster relief.

Diesel backup generators are available in a wide range of configurations that vary based upon the application and mode of operation. Liquid-cooled diesel backup generators such as those that HIPOWER Systems offers are preferable where quiet operation is required; they also offer a more evenly controlled temperature than air-cooled backup diesel generators.

Diesel standby generators cost less to maintain than natural gas models due to a variety of factors, including the absence of a spark ignition system. They are considered more rugged and reliable in very harsh conditions and have longer operating lives. They also will perform with less frequent service intervals. Depending on the size and operating speed of the engine, a diesel backup generator may run for three times as long as its natural gas counterpart before requiring servicing.

Industrial, diesel-powered backup generators for standby backup power are commonly found in agricultural, construction, forestry, hospital, marine, mining, telecommunications and underground applications. Diesel standby/backup generators can be outfitted with bi-fuel systems to burn natural gas, as well.

Standby/Backup Natural Gas Generators

Fuel-source reliability and environmental regulations or concerns are the primary reasons why organizations select natural gas generators for standby or backup power. Where generators may go long periods without being run other than for testing, concerns about long-term diesel storage is also a concern.

These considerations are not insignificant, making the choice of natural gas a necessity, or even a directive, for many firms. Natural gas is also less expensive than diesel, although it generally takes much longer to recapture the cost differential for a standby natural gas generator (as compared to diesel) than for a prime power unit.

  • The availability of underground natural gas lines gives natural gas generators a reliable fuel supply if above-ground disasters strike. Having a continuous supply eliminates the need for fuel storage and scheduled deliveries. This enables natural gas backup generators to meet the rigorous guidelines of cities and other urban areas concerned with the possibility of fuel tank explosions.
  • Standby natural gas generators can be interconnected with the utility grid through an automatic transfer switch. In the event of a power disruption, they can start automatically and then shut themselves off when power is restored. Some of these units can also test themselves automatically on a regularly scheduled basis.
  • In urban areas, local or state governments may have enacted regulations prohibiting the use of diesel engines due to emissions concerns. Even though the current generation of diesel engines burns far cleaner than in previous years, natural gas is still considered a more environmentally friendly choice.
