Why Fort Worth Homeowners Act
Fort Worth's Power Outage Reality
Fort Worth runs on the ERCOT grid like the rest of Texas, and the threats are the same ones that hit Dallas: severe spring and summer storms, the occasional tornado, and the kind of winter event that took the state down. The grid here doesn't get help from neighboring states when it's overwhelmed. That's the part most homeowners don't think about until they're sitting in the dark.
Oncor runs the wires across Tarrant County. When Winter Storm Uri hit in February 2021, ERCOT failed at scale and around 172,000 Oncor customers in Tarrant County were without power on the afternoon of February 16, many for days in subfreezing temperatures. The May 28, 2024 derecho left more than 650,000 Oncor customers without power across North Texas, and May and June every year bring straight line wind events that can take a neighborhood offline for hours or days.
The daily reality is more mundane but still costs you. A summer pop up thunderstorm with hail can take a single substation offline and darken several zip codes. A standby generator starts on its own within seconds of the lights going out and runs until Oncor restores service, whether you’re out for an afternoon or a long week.
February 2021, the week the grid failed. Fort Worth went days without power in record cold.

North Texas runs one of the highest severe weather counts in the country. Most Fort Worth outages come from routine storms, not the headline events.

Fort Worth Pricing Guide
What Does a Generator Cost in Fort Worth?
Installed in Fort Worth, a whole home generator runs $7,000 to $25,000+. The number depends on unit size, fuel source, and a few details about the property.
Essential circuits (lights, fridge, AC unit)
Most homes under 3,000 sq ft (full house)
Larger homes, multiple HVAC zones
Large homes, home offices, medical equipment
That price includes the equipment, our install crew, the automatic transfer switch, Fort Worth permit fees, and the 12 year Power Plus warranty. If you're on Atmos Energy gas, connecting to an existing line stays inexpensive. The estimate assumes there's an existing fuel source at the property.
Because Grasten Power installs with our own crews instead of subcontractors, we cut out the outside markup that pushes installation costs higher at other companies. As a multi brand dealer, we match you with the unit that fits your home and budget rather than the only one on the shelf. The result is a higher quality installation at a fair price.

Exclusive Power Plus Warranty 12 Years of Full Coverage
Every Generac air-cooled installation we do includes the full 12 year Power Plus Warranty at no extra cost, covering parts and labor for 12 full years beyond the standard manufacturer warranty.
Choosing Your Generator
Comparing Your Options for a Fort Worth Home
Grasten Power is one of the few dealers in Tarrant County authorized to install and service all four leading brands. Here's how Generac, Kohler, Cummins, and Briggs & Stratton compare for Texas homeowners.
Generac
The most widely installed whole home generator brand in the United States. Generac offers the broadest range of residential standby units (11kW to 24kW+ air-cooled) and a mature remote monitoring platform (Mobile Link). Strong parts availability and the largest dealer network make Generac the practical choice for most Texas homeowners.
Kohler
Known for quieter operation and premium build quality. Kohler residential generators are often preferred by homeowners who prioritize noise levels (especially relevant in denser neighborhoods and HOA communities). Commercial-grade engineering translated into residential units.
Cummins
Industrial-grade engineering scaled for the home. Cummins backup generators carry the same engine heritage that powers commercial fleets, with sizing options that comfortably cover larger Texas homes, multi-HVAC properties, and homes with elevators or pools. Diesel and natural gas configurations available.
Briggs & Stratton
Value-tier standby generators built by one of the most established names in residential power. Briggs & Stratton units are a strong fit for homeowners who want reliable backup at a lower entry price, or who only need to cover the essential circuits of a smaller home.
The free estimate covers all four brands against your specific home, neighborhood, and HOA. There’s no upside on our side to push one over another. We just want the right unit on your pad.

What Fort Worth Homeowners Say
Fort Worth Homeowner Questions
Fort Worth Generator Questions, Answered
The questions Fort Worth homeowners ask before scheduling a free estimate.
How much does a whole home generator cost in Fort Worth?
Real range is $7,000 to $25,000+ turnkey, and most Tarrant County jobs land in the middle. A 22kW Generac air cooled unit handles the typical 2,500 square foot home. The price includes the generator, the automatic transfer switch, electrical and gas connections off an existing Atmos Energy line, Fort Worth permit fees, and the 12 year Power Plus warranty. Larger homes, longer panel runs, an electrical service upgrade, or a new gas line push the number up. The free on site estimate gives you an exact figure for your property.
Do I need a permit, and who pulls it?
Three permits are required: building, electrical, and mechanical (gas), all through Fort Worth Development Services. Grasten Power pulls everything. We submit the application, coordinate the inspections, and run any HOA architectural review (Westover Hills, Mira Vista, and most master planned communities require this). From you we need a signed Notice of Commencement and a property survey. Approval normally runs 10 to 21 business days, longer in peak storm months.
What size unit do I need for a Fort Worth home?
For 1,800 to 3,500 square feet, a 22kW or 24kW air cooled unit handles the load. The biggest draw is the AC system, which on a Fort Worth August afternoon is doing serious work. Multiple HVAC zones, homes over 4,000 square feet, an elevator, or specialty equipment push you into 26kW or larger, and that’s where Cummins becomes a serious option. The free estimate includes a load calculation. We don’t guess.
Will my HOA need to sign off?
Westover Hills, Mira Vista, the TCU area, and most newer master planned communities require architectural review before installation. The HOA wants a placement plan, screening or landscaping, and proof the generator stays under their noise standard (55 to 65 decibels at the property line is typical). Grasten Power prepares and submits the application package on your behalf. You’re not chasing board meetings.
Natural gas vs propane in Fort Worth?
Most Fort Worth addresses on city service run Atmos Energy natural gas. That’s the simpler setup: no tank, no fuel delivery schedule, the generator just pulls from the same line as the house. If your property isn’t on city gas, propane works fine, but means a 250 to 500 gallon tank on the lot and an ongoing fuel contract. Both are reliable. Cost and convenience are the trade off. We look at your specific address during the estimate.
How long does the install take?
On site work is one to two days. Day one is concrete pad, generator placement, gas and electrical connections, transfer switch. Day two, when needed, is commissioning, testing, and the walkthrough. The 30 to 90 day total timeline is dominated by permits and inspection scheduling with the city, not actual labor.
How loud will it be for the neighbors?
55 to 65 decibels during operation. Dishwasher volume. Kohler tends to come in a few decibels quieter than the others, which can matter in Westover Hills or anywhere with strict HOA noise rules. The weekly self test is 5 to 10 minutes. During an actual outage, the neighborhood is dark and the generator next door isn’t what anyone’s noticing.
Will the generator survive a tornado?
All four brands we install are engineered to handle tornado force winds. The unit sits on a concrete pad anchored to specification. What can go wrong in a major storm event is downed lines or transfer switch damage. Both are quick fixes our service team can handle. Our 12 year Power Plus warranty covers parts and labor for the full duration. If hail or wind damage hits the housing, we document it and get you a repair estimate within 48 hours for the insurance claim.
Who handles service after the install?
Grasten Power runs our own service fleet across Dallas Fort Worth. Our mobile vehicles are stocked with common parts. Our 24/7 dispatch line is a live phone, not an answering service. When a major event hits Tarrant County, our crews stay in the metro working through the call volume. Most Fort Worth customers enroll in an annual maintenance plan at installation to keep the unit and the 12 year warranty in good standing.
