Standby vs Portable Generators
A portable generator is the machine most people picture: gasoline-powered, wheeled out when the lights go off, refueled by hand, and connected to a handful of loads through cords or a manual interlock. It works, but it asks a lot of you at exactly the wrong moment. Someone has to be home, the tank has to be full, the cords have to be run, and it has to live outside while it runs because of exhaust. It also stops the moment the gasoline does, which during a long outage means trips to whichever gas stations still have power.
A standby generator removes all of that. It is permanently installed, fed by natural gas or propane so there is no tank to fill, and wired into the panel through an automatic transfer switch so the changeover happens on its own. It starts whether you are home or not, which matters most for the failures you do not see coming: a refrigerator and freezer full of food, a sump pump during a storm, medical equipment, or an HVAC system in a Texas July. The trade-off is that it is a bigger upfront project, which is why sizing it correctly the first time matters.
How an Automatic Transfer Switch Works
The automatic transfer switch, or ATS, is the brain of the system, and it does two jobs. The first is detection: it monitors the utility feed, and when the voltage drops out it signals the generator to start, waits a few seconds for it to come up to speed, and then transfers your backed-up circuits from the grid to the generator. When utility power returns and holds steady, it transfers the load back and tells the generator to shut down and cool off. The whole sequence is automatic, and a typical outage shows up in the house as a brief flicker rather than a dark evening.
The second job is safety. The ATS makes it physically impossible for the generator and the grid to feed the same wiring at the same time. Without that isolation, a generator can backfeed the utility lines, which is dangerous for the line crews working to restore power and is exactly the kind of mistake that code-compliant, inspected installation work exists to prevent.
Sizing the Generator to Your Home
Sizing starts with a question, not a spec sheet: what do you actually need running during an outage? Some homeowners want essentials only - the refrigerator, some lights and outlets, the internet, maybe a furnace blower - which a smaller unit and a selected set of circuits can cover. Others want the whole house to carry on as normal, central air conditioning included, which calls for a larger unit and a transfer switch that handles the full service. Air conditioning is usually the deciding load, because compressors draw heavily at startup and a generator has to be sized for that surge, not just the steady running load.
Your electrical panel is part of the answer too. We run a load calculation, look at the panel's capacity and breaker layout, and confirm it can accept the transfer switch and any new circuits. An older panel that is already full sometimes needs attention before backup power can be added, in which case we fold that work into the same project; see our page on electrical panel replacement in Fort Worth for how that goes. And if there is a future load on your wish list, like a home EV charger circuit, the time to account for it is during sizing, not after the generator is in.
Why Texas Homes Add Standby Power
North Texas gives you more than one reason. Summer thunderstorms and high winds take down lines, summer heat pushes the grid hard, and winter showed its own worst case in February 2021, when Winter Storm Uri left millions of Texas homes without power, many of them for days, in freezing temperatures. That event is the reason a lot of Fort Worth homeowners started pricing standby generators, and it reframed backup power from a convenience into a plan for keeping a home heated, plumbing unfrozen, and food safe when the grid cannot do it. A generator will not fix the grid, but it does mean the next regional outage is something that happens outside your house instead of inside it.
Storm season is also worth thinking about at the panel itself. The same weather that causes outages causes voltage surges when power drops and returns, and a surge device at the panel protects the electronics, appliances, and HVAC controls in the house. Since the electrician is already working in the panel during a generator installation, it is a natural time to add whole-home surge protection in the same visit.
Natural Gas or Propane
Standby generators in this area run on natural gas or propane, and which one fits your home is usually decided by what is already there. A home with natural gas service typically uses it: the supply is effectively unlimited, there is no tank to monitor, and the generator can run as long as the outage lasts. We confirm the gas meter and line can deliver the flow the generator needs, since a larger unit sometimes calls for a meter or line upgrade, which gets coordinated as part of the install.
Propane is the answer where natural gas service is not available. The generator runs the same way, but the fuel lives in a tank on the property, so the practical questions become tank size, placement, and keeping it filled ahead of storm season. Either fuel beats gasoline for a standby unit, because the system can start and run unattended without anyone hauling fuel cans during an outage.
Permits, Code, and a Licensed Contractor
A standby generator installation is permitted electrical work. The unit has to be placed with proper clearances, the transfer switch has to be wired and grounded to code, the fuel connection has to be done right, and the finished job gets inspected. Breeze handles that as the licensed electrical contractor of record (TECL34012): we pull the permit, do the work to code, and schedule the inspection so the system is documented, safe, and ready to run. That paperwork also matters later, at resale or for insurance, when an unpermitted generator becomes a problem instead of a selling point.
Maintenance Basics
A standby generator is an engine that spends most of its life waiting, so maintenance is what guarantees it actually starts. The unit runs a brief self-test on a schedule to keep itself exercised, and beyond that it needs the things any engine needs: periodic oil and filter changes, battery checks, and an annual inspection to catch worn parts before an outage finds them. We service and repair the generators we install, and we maintain Generac units other companies installed, so an existing system that has been neglected is worth a call rather than a replacement assumption.
