When the power goes out in Texas, it can shut down more than just lights. From home air conditioning to business operations, you depend on electricity every minute of the day. With Texas’s unique grid setup and unpredictable weather, having a plan for what to do in an emergency is essential.
The Growing Need for Emergency Power in Texas
The Electric Reliability Council of Texas (ERCOT) oversees the state’s independent power grid. However, while Texas can regulate its own electrical market, it cannot get power from nearby states when the grid is under stress.
The consequences were evident during Winter Storm Uri in 2021, when power plants and gas supply froze, and millions lost heat and electricity for days. In the years since, extreme summer heat has created its own strain as record demand pushes the grid close to its limits during peak afternoons and evenings.
The weather is just one factor. Outages can happen due to aging infrastructure, equipment failures and line damage. Demand is also rising fast as data centers, industrial facilities and population growth increase electricity use.
The U.S. Energy Information Administration projected that national retail electricity sales to end users could rise about 2.2% per year in 2025 and 2026, after averaging only 0.8% growth from 2020 to 2024. The agency attributes much of this increase to rapid demand growth in the ERCOT region, where usage is expected to rise by roughly 11% across 2025 and 2026.
A study ranks Texas second in the U.S. for summer outage risk based on events affecting more than 5,000 customers from 2019 to 2023. Over that period, the state had 7,164 summer outages, and the highest total hours without power per year at around 35,440 hours on average.
For homeowners, losing power can quickly lead to health and safety issues when cooling or heating is unavailable. Medications can spoil and security systems can go offline. For businesses, every hour of downtime can mean lost revenue, damaged inventory and disruptions to operations.
What to Look For in an Emergency Power Company
You need a partner that understands your needs and can respond when it matters most. Start by thinking about your usage needs. Some companies only want a piece of equipment, such as a standby generator for an industrial facility, and have internal staff manage everything else. Many homeowners and small businesses prefer a full-service provider that handles assessment, sizing, installation, permits, fuel setup and long-term maintenance.
If you’re thinking of renting for outages, confirm that the provider has a structured deployment process in place. Look for companies that already work with established manufacturers and provide equipment that meets current standards and codes.
Local presence also matters. Providers with service teams in the area know more about the hazards of bad weather, what permits are necessary and how to ensure compliance. They can also reach you more quickly for service calls, fuel issues or emergency repairs. Those that regularly service residential, commercial and industrial clients tend to have a broad view of load profiles and critical systems.

What Size Generator Do I Need For my Home or Business?
Generator capacity is measured in kilowatts (kW), and the right size depends on what you need to keep running. There is no universal number. For homes, you can choose between essential-circuit coverage and whole-home coverage. Essential-circuit systems power only critical items, such as your refrigerator, some lighting circuits, medical equipment and possibly a small air conditioning unit or heater. Whole-home systems are sized to handle your HVAC, kitchen, laundry and other major loads.
Sizing is more complex for businesses, as the load calculation has to account for critical machinery, servers, lighting, HVAC and any process-specific equipment. Starting currents for motors and compressors also matter. A professional load assessment is the safest way to determine the capacity needed to prevent disruptions and equipment damage.
What Factors Determine the Total Cost of a Generator System?
The total cost covers more than the unit itself. The generator is the largest single component. Larger kW ratings and premium brands cost more, but they may also provide longer life or better performance. Your application and runtime needs will guide this part of the budget.
The automatic transfer switch is another element. It switches your electrical system between grid and generator power and must be properly sized and configured. In many cases, it is priced separately.
Installation labor comes next. It covers electrical work, fuel piping, concrete pad separation and any trenching or panel upgrades. The distance between the generator and your electrical panel or fuel sources can influence this cost. Permits and municipal fees are also part of the overall price, as are any sound enclosures or special foundations.
Overall, the most accurate way to determine pricing is to request a detailed on-site quote from an experienced provider.
Powering Your Preparedness for the Future
Securing emergency power solutions in Texas is a practical step toward protecting your home, business and community from an increasingly stressed grid. The right approach depends on your situation, whether you need a compact home standby unit, a dedicated generator service partner or a large-scale equipment provider for industrial and utility operations.
