An automatic standby generator is a back-up electrical system that operates whether you are at home or away. It automatically supplies power to  your home or business within 30 seconds of a utility failure. After utility power returns, the generator shuts itself off and awaits the next outage. It operates on natural gas or liquid propane and sits outside your house or business just like a central air conditioning unit.

While portable generators do supply power, the poor quality of the electricity can damage your sensitive electronics such as computers, laptops, and televisions. A professionally installed standby generator provides a level of reliability and safety unmatched by portable generators. Standby generators operate automatically as you weather the storm in safety. On the other hand, portable generators require constant attention, the use multiple extension cords, and frequent refueling, increasing the risk of hazardous fumes, fire, and electric shock.

During a utility power outage, an automatic standby generator provides numerous advantages over a portable generator:

• The American Red Cross recommends permanently installed standby generators as a safer way to provide backup power to a home than a portable generator.

• With an automatic standby generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators.

• Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and does not need to be refilled.

• They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords throughout your home.

• They provide protection 24/7, whether you're home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.

Example: Weekly exercise time (11 hours per year) plus four 20 hr. outages (80 hrs/year) equals 91 hours of operation per year OR over 30 years.
