When Texas Weather Strikes: Your Complete Guide to Choosing Between Whole House and Portable Generators
Texas homeowners know all too well the reality of unpredictable weather and its impact on power reliability. Texas experiences over 100 days of thunderstorms annually, along with frequent hurricanes and severe winter storms. The February 2021 winter storm alone left 4.5 million Texans without power for days. Texas had 210 weather-related power outages — more than any other state — from 2000 to 2023, making backup power solutions not just a luxury, but a necessity for many families.
When it comes to protecting your home and family during outages, the choice typically comes down to two main options: whole house generators and portable generators. Each has distinct advantages and drawbacks that Texas homeowners should carefully consider.
Understanding Whole House Generators
Whole-home generators, also known as standby generators, are stationary fixtures. They’re connected to your home or business’ electrical system as well as a fuel source, such as natural gas lines or propane tanks. In the event of a power outage, the whole-home generator is automatically notified through the electrical system and kicks on in seconds, powering on your furnace, kitchen appliances, television, lights, well-pump, etc.
The convenience factor cannot be overstated. Whole house generators start automatically during a power outage. There’s no need for manual intervention. Because whole-home generators tap into a natural gas or propane source, you don’t have to trudge out into the cold to refuel the generator with smelly gas or diesel. When the electrical outage is over, the generator turns itself off. Whole-home “standby” generators operate automatically providing hands-free operation throughout the year, even when you’re not there.

Portable Generator Advantages and Limitations
Portable generators are movable units that can be used to power specific appliances or areas during an outage. These generators have lower power capacities compared to whole house generators. They are ideal for powering essentials, like lights and small appliances.
The main advantages of portable generators include their lower upfront cost and versatility. Power output: 3,000 to 8,500 watts Price range: $400 to $1,500. When a large portable model is connected to your home’s circuit-breaker panel with a transfer switch, it can power almost as much as a home standby generator. Plus, I can use my portable at the beach, on camping trips, work sites, etc., something you can’t do with a whole-home system. I might be easier with a whole home, but why pay tens of thousands of dollars for a system that hardly gets used? I did my manual system for less than $3k.
However, portable generators come with significant drawbacks. Portable generators require manual setup and operation. You need to start them and connect them to the desired appliances. The portable models in our generator ratings run on gasoline, burning through 12 to 20 gallons per day depending on the unit’s output and the load being powered. This means you’ll have to store a significant quantity of gasoline, start the generator manually, and refill it (when it’s off, to minimize fire danger) after running it for several hours.
Cost Considerations for Texas Homeowners
The financial investment varies dramatically between the two options. In Texas, the total cost of a whole-home generator, including the unit and installation, typically ranges from $13,000 to $20,000 or more. Here’s a breakdown for an average-sized home: Small home (10-14 kW generator): $13,000 to $15,000+ Medium home (20-24 kW generator): $15,000 to $16,000+ Large home (25 kW+ generator): $16,000 to $20,000+
In contrast, whole-house generators can range in price from $2,000 to $7,000. By comparison, large portable generators that power a whole house start at around $1,000. However, they require professional installation, sometimes involving a plumbing/heating contractor for a gas line, a general contractor for the concrete pad, and an electrician to hook up the generator to your electrical panel. The installation can be more expensive than the unit itself, ranging from about $2,000 to $20,000 or more.
Safety and Reliability Factors
Safety considerations are paramount when choosing between generator types. No matter what you do, you ABSOLUTELY MUST make sure you don’t backfeed power onto the grid. You run the risk of injuring someone who might be working on a down line. If you’re powering your house from a generator, you must disconnect the house from shore power.
Portable models also tend to be noisier and produce less power than whole-house models, and they require careful placement for safety. Always run a portable generator at least 20 feet from your home and equipment such as a central air conditioner condenser or a window AC, and direct the exhaust away from the house or any other structure, including your neighbors’ homes.
Making the Right Choice for Your Texas Home
The decision ultimately depends on your specific needs, budget, and lifestyle. If you experience frequent power outages or want comprehensive coverage, a Generac whole house generator is the best option for your Houston home. For temporary or infrequent use, a portable generator may be a suitable and more affordable solution.
Best for: Families who have frequent outages that often last a long time and are willing to pay for the convenience of a nearly seamless transition to a generator that will run almost indefinitely when the power goes out. Given Texas’s history of severe weather events and grid reliability challenges, whole house generators offer superior peace of mind for families who can afford the investment.

Whether you choose a whole house generator for maximum convenience and reliability, or a portable generator for budget-conscious backup power, the key is having a plan before the next storm hits. As the grid has become less reliable in Texas, demand for generators has grown — especially in Houston. Since the February 2021 freeze, it’s really been a very active market. For most people … every time they have another outage, they get closer and closer to saying, ‘That’s it. I’m ready to spend money to solve this problem because I can’t depend on whoever my utility is to provide power.’
