Generac explains how a standby generator works here.  

Colorado's best certified standby generator installers, Roy's Electric Colorado sells, installs, maintains, and does warranty work for standby generators, in home or small business.  Keep the power on and your business open, or your home comfortable (and your refrigerator and freezer goods safe)!  A permanent backup power system.

Installed on the outside of your home or business, similar to an air-conditioning unit.  The standby generator sends power to the electrical system of the entire home.  We are certified by the following top manufacturers, including Briggs & Stratton, GE Generator, Generac and Kohler Generators.


The standby generator comes on automatically whether you are in the home/business or not, and it all happens within seconds of any power outage.  Whether working for a couple of hours, or a day or two, a standby generator offers peace of mind when those impressive storms hit.

No re-fueling is necessary because standby generators run on natural gas or natural gas generator!  Natural gas and propane are the fuels typically used.  

GE Generators offers a Generator Size Calculator to find out just the right size for your location & application.
