A standby generator is the difference between riding out an outage and living through one. North Texas homeowners know the pattern: summer thunderstorms that knock out power for hours, ice events that take down lines for days, and a grid that gets stressed exactly when you need air conditioning or heat the most. Grizzly Electrical Solutions installs permanently mounted, automatically switching standby generators across the Dallas–Fort Worth metroplex — sized correctly for your home, permitted properly, and wired by licensed electricians who do this work every week.
A portable generator can keep a refrigerator and a few lights alive if you're home, awake, and willing to run extension cords through a cracked door in the rain. A standby generator is a different category entirely. It's permanently installed on a pad outside your home, connected directly to your electrical system through an automatic transfer switch, and it starts itself within seconds of an outage — whether you're home, at work, or on vacation. No cords, no gasoline runs, no carbon monoxide risk from a machine running too close to a window, and no decisions to make at 3 a.m. When utility power comes back, it switches you over and shuts itself down. For families with medical equipment, home offices, freezers full of food, or anyone who simply refuses to lose a week of comfort to a storm, standby is the answer.
The most common question we get is "how big a generator do I need?" For most whole-home installations in DFW, the answer lands in the 20–22kW range — enough to run central air conditioning, the refrigerator, lights, outlets, and the rest of a typical household load at the same time. Air conditioning is the deciding factor in Texas: a large AC condenser is the single biggest load in most homes, and it dominates the sizing calculation. Smaller units in the 10–14kW range work for partial-home setups where you pick essential circuits instead of backing up everything. We start every install with a load assessment of your actual home — square footage, AC tonnage, electric vs. gas appliances, EV charger if you have one — and size the unit to the real numbers, not a guess. If your service panel is undersized or due for attention, we may recommend pairing the project with a panel upgrade so the whole system is ready for the load.
Standby generators run on one of two fuels, and your home usually decides which:
The transfer switch is what makes a standby system "standby" instead of "a very expensive portable." It monitors utility power constantly. When the grid drops, it isolates your home from the utility lines — a critical safety function that protects line workers and your equipment — then signals the generator to start and moves your home's load onto generator power. When the utility returns and stabilizes, it switches you back and lets the generator cool down and shut off. Whole-home systems use a service-rated transfer switch installed between the meter and your panel; partial-home setups use a switch that feeds a selected set of essential circuits. Either way, the changeover is automatic, safe, and code-compliant — and it's work that must be done by a licensed electrician.
A full standby system is the premium solution, and it's not the right fit for every budget. If you want real backup power at a fraction of the cost, a generator inlet with an interlock kit is the smart middle path: we install a weatherproof inlet on the outside of your home and a code-compliant interlock on your panel, so a portable generator can safely back-feed selected circuits without extension cords through windows. You trade automatic switchover and whole-home capacity for a much lower price tag — and you can always upgrade to a standby unit later. It's the most popular backup-power project we do, and we're happy to walk you through both options on the same call.
A standby generator project has a few moving parts, and we manage all of them. It starts with the site assessment and load calculation, then the permit filing with your city — generator installs require electrical permits across DFW, and gas work requires its own permit and inspection. The unit sits on a concrete or composite pad with required clearances from windows, doors, and the property line. On install day, we set the generator, run the electrical connection through the transfer switch, and coordinate the gas line connection with a licensed plumber where needed. After the city's inspection, we start the unit, test the full transfer sequence with a simulated outage, and walk you through the weekly self-test cycle and basic maintenance schedule. You end up with a system that exercises itself every week and texts nobody about it — it just works when you need it.
Standby generator pricing varies more than almost any other project we quote, because every home's situation is different. The main drivers:
Call us for a site assessment and a written quote — and if the numbers point you toward the inlet-and-interlock route instead, we'll say so. Protecting the generator and your home's electronics from grid-side spikes when power returns is worth a conversation too: see our whole-home surge protection page for how that layer works.
We install standby generators across the metroplex from our base in Rowlett: Rowlett, Rockwall, Garland, Sachse, Wylie, Murphy, Plano, Dallas, Fort Worth, Frisco, Arlington, Royse City, Irving, Grapevine, Richardson, McKinney, and Farmers Branch. Planning a generator alongside an EV charger? The two projects share panel capacity considerations — our EV charger installation page covers what that load looks like.
Most whole-home installations in DFW land in the 20–22kW range, driven mostly by your air conditioner's load. Smaller 10–14kW units work if you only want essential circuits backed up. We do a real load assessment of your home before recommending a size — square footage alone doesn't tell the story.
If your home has natural gas service with enough capacity, that's usually the way to go: no tank, no refills, unlimited runtime. Propane is the standard solution for homes without gas service and works perfectly well — it just needs a properly sized storage tank on the property.
Yes. Generator installations require electrical permits in every DFW city we work in, and the gas connection requires its own permit and inspection. We handle the filings, the inspection scheduling, and the utility coordination — you don't touch the paperwork.
Equipment lead times vary by manufacturer and season — demand spikes after every major Texas outage event. Once the unit is in hand, the physical installation is typically a matter of days, plus the city's inspection schedule. We'll give you a realistic timeline at the quote stage rather than a best-case fantasy.
Absolutely, and a lot of homeowners do exactly that. The inlet-and-interlock setup gets you safe backup power now at a fraction of standby cost, and nothing about it gets in the way of a future standby installation. It's a sensible stepping stone, not a dead end.
