Entergy's Conroe Network, which covers Conroe, Montgomery and Willis, still had about 57,000 customers out on the third day. Winter Storm Uri in February 2021 put 57,966 Entergy customers in Montgomery County in the dark on the afternoon of February 15, and about 45,000 were still out the next morning. Hurricane Ike in September 2008 cut power to about 390,000 Entergy Texas customers, about 99 percent of its customers.

The City of Conroe Building Inspections and Permits Department issues the permit through its OpenGov portal and has adopted the 2026 National Electrical Code. Grasten pulls the permit with a licensed electrician and schedules the inspections.

Why Conroe Chooses Grasten
What Makes Us Different
Multi Brand Dealer
Conroe is home turf: our facility at 10890 TX-242 is about 4 miles away. Because we sell four brands, a larger house with heavy loads might get a Cummins, while essential circuits on a tighter budget often point to Briggs & Stratton instead.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Entergy's Conroe Network still had about 57,000 customers out on the third day after Beryl. A Generac air-cooled unit installed by Grasten carries 12 years of coverage on parts, labor, travel and major components, a $1,499 value that costs you nothing extra.
12 Years of Full Coverage

Whole home installs in the Houston area typically run $7,000 to $25,000+. Here's where most Conroe homes land.

Larger homes, multiple HVAC zones
Large homes, home offices, medical equipment
Prices include equipment, in-house installation, transfer switch, City of Conroe permit fees, and our 12-year warranty. Where a CenterPoint gas main reaches your street, a natural gas connection typically adds minimal cost compared with a propane tank installation.
Most Conroe homes on city gas service run natural gas. CenterPoint Energy Gas covers most of the metro, and the generator pulls off the same line that already feeds the house.

Frequently Asked Questions
Conroe Generator Questions, Answered
Do I need a permit to install a generator in Conroe?
Yes. Inside the city the permit comes from the City of Conroe Building Inspections and Permits Department; since December 2025 every application, inspection request and payment goes through the city’s OpenGov portal, and the city inspects to the 2026 National Electrical Code. A Conroe address outside the city limits goes through the Montgomery County Permit Department in Conroe. Grasten pulls the permit with a licensed electrician and schedules the inspections.
What knocks out power in Conroe?
Hurricanes and summer storms on the overhead lines, and the occasional grid failure. When Hurricane Beryl came through in July 2024, 247,000 Entergy Texas customers were without power by the first evening, and about 110,000 Montgomery County customers were still out two days later. Entergy’s Conroe Network, which covers Conroe, Montgomery and Willis, still had about 57,000 customers out on the third day. A standby generator starts on its own within seconds and runs until Entergy restores service.
Is natural gas available at my Conroe address?
Often, yes. CenterPoint Energy Entex serves Conroe. 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 Conroe 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 Conroe for repairs?
Conroe is served from our Conroe facility at 10890 TX-242, about 4 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.
