A Spectrum News report this week cited energy experts saying the Texas power grid is prepared to handle extreme heat this summer. ERCOT has added generation capacity. Demand response programs are broader than they were in 2021. The headline is reassuring.

Here is what it does not tell you: grid-level stability and your household's actual experience during a heat event are not the same thing. The grid can hold, and your power can still go out — for a few hours, for a day, or long enough to matter — because of a transformer on your street, a substation in your ZIP code, or a rolling conservation appeal that your utility runs quietly at 4 p.m. on a 107-degree afternoon.

Texas families who went through February 2021 know this distinction by feel. The question heading into another brutal summer is not whether ERCOT will collapse. It is whether your household can handle a 24- to 48-hour disruption without it becoming a medical emergency or a financial crisis.

What's actually different this summer

ERCOT's reserve margins have improved since the Uri disaster. The grid operator has more dispatchable capacity on call and better demand-side tools. That is real progress, and it matters.

What has not changed: Texas summers keep setting heat records. The window from late June through early September now regularly produces multi-day stretches above 100°F across the Hill Country, DFW, Houston, and the Rio Grande Valley. At those temperatures, the risk profile is not about the grid failing entirely — it is about localized stress, neighborhood-level outages, and the human cost of even short-duration heat exposure for children, elderly residents, and anyone without a resilient cooling setup at home.

ERCOT also issues conservation appeals — voluntary requests to reduce consumption during peak hours — without those making headlines. If you have not signed up for your utility's outage alerts, you may not know one is happening until the lights are already dim.

What we'd actually do

Sign up for your utility's text and email alerts this week. Every major Texas utility — Oncor, CenterPoint, AEP Texas, TNMP — runs a free alert program. Knowing a conservation event is coming at 3 p.m. lets you pre-cool your house, charge devices, and fill water containers before the peak window hits. This takes four minutes to set up and costs nothing.

Running your thermostat at 78°F during the peak hours (typically 3–7 p.m.) instead of 72°F meaningfully reduces strain on both the grid and your July electric bill. If you have a smart thermostat, program a summer schedule now rather than adjusting it reactively each day. Most Texas utilities also offer free or discounted smart thermostats through their energy efficiency programs — check your provider's website before buying one at retail.

Identify your household's one critical heat vulnerability. This is the specific thing that would make a 24-hour outage dangerous rather than just uncomfortable: a family member on electric-dependent medical equipment, an infant, a dog in an upstairs room, an elderly parent next door. Write it down. Then build one layer of redundancy around that specific vulnerability — a battery-powered fan, a backup power station with enough capacity to run a CPAP for a night, a plan to drive to a friend's air-conditioned home. One targeted fix beats a general gear shopping list.

Locate your nearest cooling center now, before you need it. Every major Texas county operates cooling centers during heat emergencies, and most open during ERCOT conservation events. Harris County, Dallas County, Bexar County, and Travis County all publish lists online. Find the one nearest your home and save the address in your phone. The friction of looking it up during an actual emergency is higher than you think.

Do a five-minute review of your freezer and refrigerator load. A full freezer holds temperature for roughly 48 hours if the door stays closed; a half-empty one loses it faster. If an outage is forecast, fill empty freezer space with water in zip-lock bags. This is the cheapest insurance you can buy for protecting food — and it doubles as an ice source once the bags thaw.

The bigger picture

"The grid will hold" is a grid operator's job to say. Your job is something different: it is to make sure your household can absorb a short disruption without it cascading into a health crisis, a ruined freezer, or a panic run to a hotel at midnight. That is not pessimism. It is the quiet, boring work of durable living in a state where summers are genuinely unforgiving.

Texas has made real infrastructure progress since 2021. That progress earned the headline. What it did not earn is your assumption that the work is done.
