Porter Outage History
Why Porter Homeowners Act
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. 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.
Porter 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.
Entergy Texas serves Porter from its New Caney Network and restores outages. One company bills you and runs the lines; there is no retail provider to choose.
Porter is unincorporated, so the only permit office is the Montgomery County Permit Department in Conroe, which takes applications in person and does not run electrical inspections. Grasten's licensed electrician installs to code and handles Entergy's connection requirements.
CenterPoint Energy Entex runs the gas mains in Porter, New Caney and Roman Forest. Rural lots may have no main and run on a propane tank.

Why Porter Chooses Grasten
What Makes Us Different
Multi Brand Dealer
Porter has no retail electric provider to choose: Entergy Texas bills you and runs the lines. You do get a choice of generator, and Grasten carries four. Kohler is the quietest by a few decibels, while Generac is the most widely installed home standby brand.
Four Brands, One Recommendation
12 Year Power Plus Warranty
Porter is unincorporated, and Montgomery County does not run electrical inspections, so the quality of the install rests on the installer. Our in-house licensed electricians wire it to code, and Power Plus coverage protects the major components of a Generac air-cooled unit for twelve years.
12 Years of Full Coverage
Customized Mobile Fleet
Porter lies about 28 miles from our Conroe facility, with New Caney and Roman Forest covered too. Remote monitoring sends real-time alerts and fault codes, so a technician can load the right part from our Texas warehouse before the van heads your way.
Ready to Roll
Typically 2 to 4 weeks from estimate to power on, depending on Montgomery County permit timelines. Grasten pulls the permit with a licensed electrician and schedules the inspections. See all six differentiators and the full process on the Houston page ›
Porter Pricing
What Does a Generator Cost in Porter?
Whole home installs in the Houston area typically run $7,000 to $25,000+. Here's where most Porter 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, Montgomery County 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 Porter 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
Porter Generator Questions, Answered
Do I need a permit to install a generator in Porter?
Porter has no city, so there is no city permit. The Montgomery County Permit Department in Conroe handles county development permits in person at 501 North Thompson Street, and its program does not include electrical permits or inspections. Grasten’s licensed electrician installs to the National Electrical Code, documents the work, and handles Entergy’s requirements for the connection.
What knocks out power in Porter?
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. 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. A standby generator starts on its own within seconds and runs until Entergy restores service.
Is natural gas available at my Porter address?
Often, yes. CenterPoint Energy Entex serves Porter. 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 Porter 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 Porter for repairs?
Porter is served from our Conroe facility at 10890 TX-242, about 28 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.
