Dallas–Fort Worth · The ERCOT grid
DFW power outages:
why the Texas grid fails, and what to do.
Texas is on its own grid — and when a freeze, a heat wave, or a spring storm hits the whole state at once, it can't borrow power from anyone. Here's the honest picture on DFW outages, and how to make sure your house isn't part of the next one.

How often does Dallas–Fort Worth lose power?
More than most big metros. DFW sits on the ERCOT grid, which is isolated from the rest of the country, and it gets hit from three directions: winter freezes (2021's Winter Storm Uri was catastrophic), record-breaking summer heat that pushes the grid to repeated conservation appeals, and violent spring storms with straight-line winds and tornadoes that down lines across the metroplex. Everyday reliability is fine — it's these big events that leave tens to hundreds of thousands of homes dark.
Why is the Texas grid so unreliable during extreme weather?
Because ERCOT runs its own grid, disconnected from the two national grids. That independence keeps Texas free of federal oversight, but it also means when a freeze or heat wave hits the whole state at once, Texas can't import much power from anywhere — supply and demand have to balance inside Texas alone. When they can't, ERCOT orders rolling blackouts. That's the structural reason a Texas outage can last far longer than a quick storm blip.
What happened during Winter Storm Uri in 2021?
In February 2021 a severe winter storm froze Texas power plants and gas supply at the same moment demand spiked for heat. More than 4.5 million Texas homes and businesses lost power — many for multiple days in sub-freezing cold — and hundreds of people died. It's the clearest example of why a home that can't ride through a multi-day Texas outage is exposed, and why standby generators surged in DFW afterward.
What should I do when the power goes out in DFW?
Check the Oncor outage map to see the scope and report your outage, and watch ERCOT grid conditions during heat or cold events. Keep the fridge and freezer closed, never run a portable generator indoors or in a garage (carbon-monoxide kills), and have a plan for anyone on medical equipment — and for extreme heat or cold, which is when Texas outages are most dangerous. A whole-home standby generator removes the scramble entirely: it starts on its own and runs on your gas line.
Will a generator keep my home running through a Texas outage?
Yes — that's exactly what a whole-home standby generator is for. It auto-starts within seconds of an outage and runs on your natural gas line indefinitely, so it doesn't ration power like a battery or need refueling like a portable. Through a multi-day freeze, a heat wave with rolling blackouts, or a spring storm, your Dallas-area home simply stays on.
The permanent fix
Don't wait for the next grid failure.
A whole-home standby generator auto-starts the instant the grid drops and runs on your gas line through the freeze, the heat, and the storm. See what one costs →
