Houston Power Outages: What to Do & How to Prepare

It happens fast. One afternoon the sky turns green over Memorial, and by evening half a zip code is dark. Families drag generators out of garages, neighbors share ice, and everyone's staring at their phone waiting for an update from CenterPoint Energy.

Houston consistently ranks among the most outage-prone large metro areas in the United States. The city sits at the intersection of Gulf Coast hurricane tracks, intense summer heat loads, and an aging distribution grid that stretches across miles of tree-lined suburban streets. The result is a system where outages are not rare edge cases but a recurring fact of life that residents plan around.

Understanding why outages happen, how to track them in real time, and what protections Texas law gives you puts you in a far better position than simply waiting in the dark.

Several factors combine to make Houston outages more frequent and longer-lasting than in many other cities.

Tropical weather. The Gulf Coast funnel means Houston is in the direct path of tropical storms and hurricanes almost every season. Hurricane Beryl in 2024 left hundreds of thousands of CenterPoint customers without power for days, and that event triggered a wave of PUCT scrutiny and legislative attention that was still shaping utility policy into 2026.

Extreme heat. Summer demand peaks in Houston regularly push the regional grid hard. When temperatures stay above 95°F for days at a stretch, load on transformers and distribution lines spikes, equipment fails, and neighborhoods go dark even without a single storm cloud overhead.

Trees and overhead lines. Houston's heavily wooded neighborhoods are beautiful and shade homes, keeping cooling costs down. They also mean that a fast-moving thunderstorm drops limbs onto power lines across hundreds of distribution points simultaneously, overwhelming CenterPoint crews.

Grid scale. CenterPoint's Houston Electric service territory covers a large swath of the greater Houston area, meaning a single major weather event creates restoration challenges across a geography the size of some entire states.

CenterPoint Energy publishes an interactive outage map at their website that shows current outages, estimated restoration times, and the number of customers affected in each area. During a major storm event it becomes the most-visited page in Houston.

A few things worth knowing about how to use it effectively:

Zoom in past the county level. During widespread events the county view is too broad to be useful. Zoom to the neighborhood or street level to see whether your specific block is flagged.

Estimated restoration times shift. CenterPoint updates ETRs as crews assess damage in the field. An estimate that says midnight may move to the following afternoon once a crew finds a downed transmission line rather than a single broken pole. Treat ETRs as working estimates, not guarantees.

Report your outage directly. If your address does not appear on the map, report it through CenterPoint's website or their outage reporting line. Unreported outages sometimes fall outside the automated detection system, and a manual report can get a crew dispatched faster.

Third-party trackers. Sites like poweroutage.us aggregate utility data and can provide a broader regional view, useful for understanding whether an outage is isolated to your block or part of a multi-county event.

Texas electricity is regulated by the Public Utility Commission of Texas (PUCT). In the competitive Houston market, your Retail Electric Provider (REP) sells you the electricity plan, but CenterPoint Energy is the Transmission and Distribution Utility (TDU) that physically delivers the power. That distinction matters a great deal when the lights go out.

CenterPoint is responsible for the poles, wires, and transformers. Your REP has no control over restoration speed. Calling your REP during an outage will not speed up repairs. Call or report through CenterPoint directly.

The PUCT sets service quality standards and can investigate utility performance. After the Beryl aftermath drew intense criticism, the PUCT increased scrutiny of CenterPoint's storm hardening plans and restoration communication requirements. Consumers who believe a utility has violated service rules can file a complaint directly with the PUCT through their online complaint portal.

One important protection: if a utility crew causes damage to your property during restoration work, you have the right to document it and pursue a claim. Keep records, photograph any damage, and contact the utility's customer service in writing.

The best time to prepare for a houston power outage is well before hurricane season peaks in August and September, or before the first major heat wave of summer arrives.

Know your medical baseline. If anyone in your home depends on powered medical equipment, register with CenterPoint's Medical Baseline program. The PUCT requires TDUs to maintain such programs, and registration can mean priority in restoration sequencing and advance notification.

Build a 72-hour kit. Water, non-perishable food, flashlights, battery banks, and a battery-powered or hand-crank weather radio. The National Weather Service Houston office provides the most reliable local storm forecasts.

Generator safety is not optional. Carbon monoxide from improperly vented generators kills people every storm season in Texas. Run generators outside, away from windows and doors, always.

Freeze your freezer. Fill containers with water and freeze them before a storm arrives. A full, well-sealed freezer holds temperature far longer than a half-empty one.

Understand your lease or HOA rules. Some Houston-area HOA communities have specific rules about generators and fuel storage. Know them before you need them.

When the power goes out, the first move is confirming whether it is just your home (check your breaker panel) or your neighborhood. The CenterPoint outage map answers that within seconds.

Keep refrigerators and freezers closed as much as possible. A refrigerator holds safe temperature for roughly four hours if unopened; a full freezer for up to 48 hours. The USDA Food Safety and Inspection Service has published specific guidance on what to keep and what to discard after an extended outage.

For extended summer outages in Houston, heat is the immediate danger. The city operates cooling centers during heat emergencies. Harris County and the City of Houston both maintain lists of cooling center locations that are updated in real time during events. Check the official Houston Emergency Management or Harris County Office of Homeland Security and Emergency Management websites for current locations.

After power is restored, reset clocks, check that your HVAC is running properly, and inspect any food that was in the refrigerator. A meat thermometer is genuinely useful here: if anything was above 40°F for more than two hours, the safe call is to discard it.

Most Houston residents know they can shop electricity plans, but fewer think about how plan selection intersects with outage risk.

CenterPoint's delivery charges appear on every plan as a pass-through fee. You pay them regardless of which REP you choose, and they do not change based on your plan. What does change is your energy supply rate and, in some cases, your plan's structure around outage events.

A few plan features worth examining on your Electricity Facts Label (EFL) before signing:

Outage bill credits. Some REPs have begun offering bill credits if your power is out for an extended period. The terms vary significantly, so read the EFL carefully.

Battery backup and solar pairing. Plans designed to pair with home battery systems can change the economics of backup power considerably. If you are considering a home battery, compare plans that offer export rates or time-of-use structures.

Rate tiers and the 1,000 kWh benchmark. Texas EFLs show rates at 500, 1,000, and 2,000 kWh usage levels. As of July 2026, the lowest all-in advertised rate in the Oncor/Dallas area at 1,000 kWh is around 7.1 cents per kWh, with a median near 16.1 cents. The spread between those numbers means Houston residents in the CenterPoint territory who have not shopped recently may be leaving real money on the table. Rates differ by territory and usage level; always check the EFL for your specific situation.

Shop current plans at Power to Choose, the PUCT's official retail electricity shopping site, or compare options at ElectricRates.org's Texas page for live rates.

An extended outage is an uncomfortable but useful prompt to review your electricity contract. If your current term is ending soon, or if you are already month-to-month, a major storm season may be the right moment to compare.

Start at powertochoose.org and enter your zip code and average monthly usage. The site filters active REPs in your area and shows EFL-verified pricing at the 500, 1,000, and 2,000 kWh tiers. Look beyond the headline rate: early termination fees, recurring monthly charges, and any usage-tier thresholds all affect your real cost.

For a broader comparison that includes plan features and contract details side by side, ElectricRates.org's Texas rate comparison tool pulls live plan data across the Houston/CenterPoint territory. A few minutes of comparison shopping can move a household from the median rate toward something meaningfully lower, which compounds month after month.

Remember: switching REPs in Texas does not change how CenterPoint delivers your power or how quickly they restore your service after an outage. But it can change what you pay for that power every month.

Information moves fast during a major outage event, and the sources that matter most are official ones.

The CenterPoint Energy outage map is the primary real-time source for customer-level outage data in Houston. Bookmark it on your phone now, before you need it.

The National Weather Service Houston/Galveston office issues storm watches, warnings, and post-storm assessments. Their forecasts are more granular and reliable than most commercial weather apps during severe events.

The Houston Emergency Management office and Harris County OHSEM coordinate local emergency response and publish real-time resources including shelter locations and road closures.

The PUCT publishes utility performance information and accepts consumer complaints at puc.texas.gov. If you believe CenterPoint's communication or restoration performance fell short of required standards, that is the place to file.
