Why Frisco Homeowners Act
Winter Storm Uri in February 2021 left about 90,000 Oncor customers in Collin County without power on the afternoon of February 16, many for days in subfreezing cold. The May 28, 2024 storms knocked out power to more than 650,000 Oncor customers across North Texas in one day. Three days later about 6,200 Collin County customers were still without power. The March 2, 2023 storms left 46,855 Oncor customers in Collin County without power that evening, out of 280,159 across North Texas.
Frisco at a Glance
Power Outage Profile
The local details that shape your install: who runs the grid, who issues the permit, and which gas partners are in your area.
Oncor and CoServ Electric each serve exclusive areas of Frisco, and the city lists both utilities' outage numbers. Oncor customers choose a retail provider; CoServ members buy their power from CoServ.
The City of Frisco publishes a Residential Backup Power Installations page: a permit is required for a standby generator, filed through the Frisco Plans and Permits portal, with a separate gas-line permit inspected by the city. Grasten pulls the permit with a licensed electrician and schedules the inspections.
CoServ Gas is the larger gas utility in Frisco and Atmos Energy serves the rest; your gas bill says which. Streets without a main use a propane tank.
Winter Storm Uri, February 2021: about 90,000 Oncor customers in Collin County were without power on the afternoon of February 16, many for days in subfreezing cold.
Why Frisco Chooses Grasten
What Makes Us Different
Multi Brand Dealer
CoServ Gas runs more Frisco streets than Atmos does, and some lots have neither main. Before recommending Generac, Kohler, Cummins or Briggs & Stratton, we confirm the fuel source, check the electrical load and show you where a unit can sit on your property.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Frisco requires a separate gas-line permit for a standby generator, checked by the city's own plumbing inspectors. We pull both permits, and a Generac air-cooled install leaves with the 12-Year Power Plus Warranty: a $1,499 value, transferable for a small fee.
12 Years of Full Coverage
Customized Mobile Fleet
During Winter Storm Uri, Collin County had about 90,000 Oncor customers without power on the afternoon of February 16, 2021. Frisco is roughly 26 miles from our Dallas facility. Our 24/7 line is staffed by a person who can send out a stocked van.
Ready to Roll
Typically 30 to 90 days from estimate to power on, depending on City of Frisco permit timelines. Grasten pulls the permit with a licensed electrician and schedules the inspections. See all six differentiators and the full process on the Dallas page ›
Frisco Pricing
What Does a Generator Cost in Frisco?
A whole home generator in the Dallas-Fort Worth metro costs $7,000 to $25,000+, installed. Here's where most Frisco homes land.
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
Prices include equipment, in-house installation, transfer switch, City of Frisco permit fees, and our 12-year warranty. Where a CoServ or Atmos gas main reaches your street, a natural gas connection typically adds minimal cost compared with a propane tank installation.
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.

Frequently Asked Questions
Frisco Generator Questions, Answered
Do I need a permit to install a generator in Frisco?
Yes. Frisco has a dedicated Residential Backup Power Installations page that says a permit is still required for a standby generator. The permit comes from City of Frisco Development Services through the Frisco Plans and Permits portal, inspections are requested through eTRAKiT, and a separate gas-line permit is required; under Senate Bill 1202 a homeowner may choose a third-party inspector for the electrical work, but gas piping is always inspected by the city’s licensed plumbing inspectors. A Frisco address outside the city limits goes through Collin County or Denton County Development Services. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Frisco?
Spring and summer storms with straight-line wind and hail, the occasional tornado, and the kind of winter event that took the ERCOT grid down statewide. Winter Storm Uri in February 2021 left about 90,000 Oncor customers in Collin County without power on the afternoon of February 16, many for days in subfreezing cold. The May 28, 2024 storms knocked out power to more than 650,000 Oncor customers across North Texas in one day. A standby generator starts on its own within seconds and runs until your utility restores service.
Is natural gas available at my Frisco address?
Often, yes. CoServ Gas or Atmos Energy serves Frisco, with CoServ Gas on more Frisco streets than Atmos, so check your gas bill. Where there is no gas main on your street, the generator runs on propane from a tank on your property. We confirm which applies during the free estimate.
Will my Frisco HOA allow a whole home generator?
Many HOAs require architectural approval before installation. Grasten Power prepares the application package and goes through the review process for you, so you are not chasing board approvals on your own.
How fast can Grasten reach Frisco for repairs?
Frisco is served from our Dallas facility at 10840 Sanden Dr B, about 26 miles away. Our service vehicles are built out for first visit repairs and stocked with the parts that come up most, and our dispatch runs 24/7 with a live phone.
