Why Celina Chooses Grasten
What Makes Us Different
Multi Brand Dealer
Three utilities split Celina: Grayson-Collin Electric Cooperative, CoServ Electric and Oncor. Whichever serves your address, the right unit depends on the house, and we can compare Cummins for heavier loads, Kohler for a quieter yard, and Generac or Briggs & Stratton side by side.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Since December 2025, City of Celina Building Services takes residential permits through MGO Connect, and we handle that filing for you. Once a Generac air-cooled unit is running, its 12-Year Power Plus Warranty stays in force with annual maintenance by a Certified Canter Technician.
12 Years of Full Coverage
Customized Mobile Fleet
At about 41 miles from our Dallas facility, Celina is a trip we plan to make once. Each service van leaves loaded with the parts that come up most, built to finish on the first visit, and remote monitoring can flag the fault code beforehand.
Ready to Roll
Typically 30 to 90 days from estimate to power on, depending on City of Celina 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 ›
Celina Pricing
What Does a Generator Cost in Celina?
A whole home generator in the Dallas-Fort Worth metro costs $7,000 to $25,000+, installed. Here's where most Celina 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 Celina permit fees, and our 12-year warranty. Where a 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
Celina Generator Questions, Answered
Do I need a permit to install a generator in Celina?
Yes. The permit comes from City of Celina Building Services at 112 North Colorado Street; since December 2025 all new residential permit applications and inspection requests go through the MGO Connect portal. A Celina 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 Celina?
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 Celina address?
Often, yes. Atmos Energy serves Celina primarily, with CoServ Gas on some streets. 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 Celina 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 Celina for repairs?
Celina is served from our Dallas facility at 10840 Sanden Dr B, about 41 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.
