How a Natural Gas Standby Home Generator Works

There are four primary components to a natural gas standby home generator system, including the:

  • Natural gas standby generator
  • Automatic transfer switch (ATS)
  • Natural gas meter
  • Electric meter and breaker panel

If you plan to purchase a generator for your home, make certain to select a certified standby generator dealer and installer which has a Texas Electrical Contractors license, factory-trained technicians, and is fully insured to cover liabilities related to your home installation.

How Standby Generator Operating Systems Work

Generators are installed outside of homes (like an A/C units) and will automatically activate on if there’s a power outage, regardless of where you are. Here’s how they operate before and during a power outage:

Before Power Goes Out

The automatic transfer switch, or ATS, has 24/7 monitoring capabilities to track the electricity that’s coming into your home from the power utility company. You can generally find the transfer switch close to your home and the electric meter.

When the Power Goes Out

During an ongoing power outage, the automatic transfer switch (ATS) sends signals for the generator to activate. In a matter of seconds, the ATS relocates your home’s power from the utility to the generator.

Your Generator Powers Your Home

The generator then provides steady electricity to your home until power from your utility company is restored. After power restoration is complete, your generator seamlessly self-deactivates. You don’t have to take any actions.

You should always read a plan’s EFL details to decide if it’s a fit for you, but our system does the tedious math to help you compare estimated costs. Of course, your future bill amounts will depend on your future usage.

You will find a widget on Home Energy Club which fetches your home’s energy usage data from Smart Meter Texas (SMT) and runs calculations of the rate structures of energy plans to help you conveniently estimate the cost of energy plans you are considering, based on your prior 12 months of energy usage as reported by SMT.

In one of the text panels of the widget, you will see an authorization button. By checking the permission box above the fields in which you enter your name and email address, and clicking on the authorization button, you are authorizing Smart Meter Texas to provide us with your location’s energy usage information so that our system can run cost calculations. It’s important to note that errors can occur when developing and running calculations, and the Company does not guarantee that its cost numbers are correct. You should always read the Electricity Facts Label (EFL) for each energy plan you are considering before enrolling, and make an independent decision on whether the plan is an appropriate fit for your home based on your own calculations and all the information disclosed by energy providers in the EFL.
