Everyone knows about Texas summers. Hot, hot and more hot. We hit records in 2023 and 2024, both in temperature levels and duration of the heat.

Fewer think about Texas’ winter extremes. But as a former PUCT staff member told us, “The Texas grid is much more fragile in response to winter weather than it is to summer weather. Be prepared.”

Winter Forecast 2024/2025

During Winter Storm Uri in February 2021, 69% of Texans lost power, some for as long as 4 days. Nearly 250 people lost their lives, with most deaths caused by hypothermia and carbon monoxide poisoning.

At a seasonal briefing on December 3, 2024, a meteorologist for ERCOT, Chris Coleman, said that current climate patterns, including ocean temperatures, atmospheric patterns and soil moisture closely resemble those we had for that historic cold snap.

“We’re in a pattern now where, when we get a warm, mild winter, more times than not, we’re seeing a cold extreme. We’re in a pattern now that supports something like a Uri.” (Source: Houston Chronicle)

Winter 2024/2025 Power Outage Risk: According to ERCOT, the risk of emergency conditions during peak demand times is 8.7% this winter (’24/’25) vs. 11.6% last winter (’23/’24). Mornings from 7-8am are the most critical, due to the later sunrise Texas’ increasing use of solar power.

6 Ways to Stay Warm During a Winter Power Outage

In areas where winter weather extremes are common, people are more prepared for freezing temperatures. In Texas, the focus tends to be more on summer hurricane preparedness. That’s why we compiled this list of ways to stay warm in case of a power outage.

1. Plan Ahead with Back-Up Heat Sources: Invest in an indoor-safe radiant propane heater plus a portable propane tank so you can safely heat one room. Or, look into a portable generator, which is also useful during Texas’ hurricane season.
2. Layer Up Like a Pro: Embrace the power of layering, which traps warm air against your skin. Start with a thin, moisture-wicking base layer or thermal underwear if you have that. Then layer on multiple layers of warmer clothes like sweaters and sweatshirts. Don’t forget warm socks, hats, and mittens to maximize your heat retention.
3. Cozy Up with Blankets and Sleeping Bags: Gather all the blankets you can find, from fluffy comforters to wool throws, and move them into the room with the fewest exterior walls. Make a blanket fort and snuggle in to conserve heat. Sleeping bags can also be lifesavers, offering individual warmth and insulation. If you have a well-insulated two-story home, consider moving to the upper level, since heat rises

Don’t be a hero. If there’s an extended cold snap, don’t tough it out at home. Find a friend or family member that has power, seek out a hotel, or locate warming centers in your local area.
