A KEYE report this week described a power outage knocking out electricity for thousands of customers in Southeast Austin. The date matters: mid-July in Central Texas, where afternoon heat index values routinely push past 105°F and nighttime lows rarely drop below 80°F. An outage measured in hours isn't a nuisance — it's a health event.

What's actually happening with Texas summer outages

ERCOT, the grid operator for most of Texas, has expanded generation capacity since the February 2021 freeze. Weatherization rules now require some generators to meet cold-weather standards. But the grid's summer exposure is a different problem from its winter one.

The freeze was a supply collapse — generation fell off a cliff. Summer stress is a demand problem layered on top of aging distribution infrastructure. Local outages like the one in Southeast Austin often aren't ERCOT-level emergencies at all. They're distribution failures: a transformer that overheats under sustained load, a line that fails, a substation event. Austin Energy, which serves much of the city, handles those repairs independently of any grid-wide crisis.

That distinction matters because it changes your planning posture. A grid-wide event in Texas might last days and affect millions. A distribution-level outage in one part of Austin might last four hours — or eighteen. You don't know which you're facing until you're already in it, and your first two hours of response look identical either way.

Texas summers also mean the gap between "inconvenient" and "dangerous" compresses fast. The CDC's heat-related illness data consistently shows that indoor heat is the primary risk factor for fatalities, not outdoor exposure. A house that starts at 78°F can reach 90°F indoors within three to four hours of losing air conditioning on a 100°F day with high humidity, depending on insulation, roof color, and shade coverage. Older adults, infants, and people on diuretics or certain psychiatric medications are at accelerated risk.

What we'd actually do

Identify your nearest cooling center now, before the next outage. Austin has a network of city-operated cooling centers that activate during heat emergencies — Austin Public Health maintains a current list. If you're outside Austin, look up your county's emergency management page and bookmark it on your phone. Do this today. When the power goes out and your phone battery is at 60% and your house is already 85°F, you don't want to be Googling.

Set a household trigger temperature. Rather than waiting until someone feels sick, decide in advance: if the indoor temperature hits 88°F, the household relocates — to a cooling center, a library, a friend's house, or a hotel. Write the number down. The reason to set this threshold ahead of time is that heat impairs judgment. People routinely underestimate their own heat exposure while experiencing it.

Charge a USB battery bank every night during July and August. A 20,000 mAh bank costs roughly $30–$45 and can keep two phones alive for a full day. In an outage, your phone is your flashlight, your weather radio, your emergency alert system, and your map to the cooling center. Keeping the bank topped off costs nothing. Many Texas households have one in a drawer that hasn't been charged in eight months.

Audit what's in your fridge and freezer once a month this summer. The FDA's guideline is four hours for a refrigerator to stay food-safe if kept closed, and 24–48 hours for a full freezer. Knowing what you have — and what you'd lose — takes ten minutes and helps you make smarter decisions about when to open the door and when to cut losses. A full freezer also holds temperature longer than a half-empty one; fill gaps with water bottles.

Know your utility's outage map and text alert system. Austin Energy offers outage alerts via text. CPS Energy in San Antonio and Oncor across North Texas have similar systems. Signing up takes about three minutes and tells you whether your outage is isolated or widespread — which shapes every decision you make about how long to wait versus when to leave.

The bigger picture

The Southeast Austin outage is local and, in grid terms, probably minor. That's exactly why it's useful. It's a low-stakes rehearsal for a question every Texas household should be able to answer without hesitation: What do we do in the first two hours of a summer outage?

The goal isn't to be impervious to Texas summers. It's to have a plan that's boring enough to actually execute when you're hot, stressed, and your kids are asking what's for dinner. Durability looks like that: a cooling center address in your contacts, a charged battery bank, a temperature threshold you've already agreed on.

That's not prepping. That's just living in Texas in July.
