Plano Outage History
Why Plano 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. The Oncor outage map showed more than 7,000 customers in Plano without power the next day, and the city warned parts of Plano would stay out until Friday. The March 2, 2023 storms left 46,855 Oncor customers in Collin County without power that evening, out of 280,159 across North Texas.

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 owns the poles and wires in most of Plano and restores outages; CoServ Electric serves some Plano addresses and the city publishes both utilities' outage numbers. Oncor customers choose a retail provider; CoServ members do not.
The City of Plano Building Inspections Department issues residential permits through its online portal. Grasten pulls the permit with a licensed electrician and schedules the inspections.
Atmos Energy's Mid-Tex Division runs the gas mains in most of Plano; CoServ Gas serves a small part of the city. Streets without a main use a propane tank.

Why Plano Chooses Grasten
What Makes Us Different
Multi Brand Dealer
Generac is the most installed brand of home standby generator, yet that alone does not settle it for Plano. Grasten also carries Kohler, a few decibels quieter, plus Cummins and Briggs & Stratton, sized against your Atmos or CoServ Gas supply.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Plano permits run through the Building Inspections Department on K Avenue, and Grasten files them with a licensed electrician. Once your Generac air-cooled model is running, Power Plus covers it for 12 years, and the coverage transfers for a small fee if you sell.
12 Years of Full Coverage
Customized Mobile Fleet
The day after the May 28, 2024 storms, more than 7,000 Plano customers were still without power on Oncor's outage map. Grasten's Dallas facility is about 9 miles off, the phone is staffed 24/7, and remote monitoring sends us real-time fault codes.
Ready to Roll
Typically 30 to 90 days from estimate to power on, depending on City of Plano 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 ›
Plano Pricing
What Does a Generator Cost in Plano?
A whole home generator in the Dallas-Fort Worth metro costs $7,000 to $25,000+, installed. Here's where most Plano 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 Plano 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
Plano Generator Questions, Answered
Do I need a permit to install a generator in Plano?
Yes. The permit comes from the City of Plano Building Inspections Department at 1520 K Avenue, Suite 140, and residential permits are applied for online. A Plano address outside the city limits goes through Collin County Development Services in McKinney (Citizen Self-Service portal). Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Plano?
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 Oncor restores service.
Is natural gas available at my Plano address?
Often, yes. Atmos Energy serves Plano for most addresses, with CoServ Gas on a small part of the city. 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 Plano 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 Plano for repairs?
Plano is served from our Dallas facility at 10840 Sanden Dr B, about 9 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.
