Texas Power Outage Survival Guide: Hurricanes, Derechos, And Winter Grid Failures Preparedness
How Texas homeowners prepare for hurricanes, derechos, and winter grid failures: outage risks by region, what ERCOT-grid utilities like Oncor and CenterPoint restoration really looks like, and the backup power options that work.
Winter Storm Uri left 4.5 million Texas homes dark in 2021, and ERCOT's summer conservation alerts haven't stopped since. Between hurricanes on the Gulf Coast, derechos in Houston, and a grid that stands alone, Texas homeowners are installing backup power faster than any state in America. This guide covers what Texas homeowners should do before, during, and after an outage, and how to make the next one a non-event.
Before the outage: the 30-minute prep
Store water (one gallon per person per day), charge battery banks, photograph your electrical panel (it speeds up any future generator sizing), know where ERCOT-grid utilities like Oncor and CenterPoint outage maps live, and keep a printed contact list. If anyone in the home depends on powered medical equipment, register with ERCOT-grid utilities like Oncor as a medical-needs customer and have a battery bridge like an EcoFlow unit rated for the device.
During: safety first
Never run a portable generator indoors, in a garage, or near windows: carbon monoxide kills {n} residents nearly every storm season. Keep fridge and freezer doors closed (4 hours safe for a fridge, 48 for a full freezer). Report the outage rather than assuming neighbors did.
The permanent fix
A whole house standby generator turns hurricanes, derechos, and winter grid failures from an emergency into an inconvenience: power restored automatically in under 30 seconds, running on natural gas or propane for as long as the outage lasts. For shorter, more frequent interruptions, a battery system (Tesla Powerwall, EcoFlow) covers essentials silently. Many Texas homes pair both. Free sizing from your electric bill, statewide from Houston to Conroe.
Quick Answers
How long do power outages last in Texas?
Routine outages run 2 to 8 hours, but hurricanes, derechos, and winter grid failures events in Texas have produced multi-day outages, with rural restoration on ERCOT-grid utilities like Oncor and CenterPoint lines sometimes stretching past a week. A standby generator or battery system is the only way to control that timeline yourself.
What should be in a Texas outage kit?
Water, shelf-stable food, flashlights (not candles), battery banks, medications, a battery or crank radio, cash, and printed key phone numbers. Our founder's bilingual book When the Lights Go Out / Cuando Se Va La Luz covers the full checklist.
Do you serve all of Texas?
Yes: Houston, Dallas, San Antonio, Austin, Fort Worth, El Paso and statewide, with equipment supplied factory-direct and installation by independent licensed Texas contractors.
