Austin: Texas could face sudden episodes of extreme cold this winter, posing a serious test to the state’s electric grid, the chief meteorologist for the Electric Reliability Council of Texas (ERCOT) warned on Tuesday. The forecast has raised concerns reminiscent of the devastating Storm Uri in 2021, which caused widespread blackouts and fatalities.
“We’re in a pattern that supports something like a Uri this winter,” said Chris Coleman, ERCOT’s chief meteorologist, during a board meeting. “The more I look at this winter, the more cold potential I see.”
Lessons from Storm Uri
Storm Uri, which struck Texas four years ago, left millions without power, disrupted businesses, and claimed over 240 lives. The catastrophe prompted state authorities to begin overhauling the electric grid to bolster reliability. However, the predicted severe weather for early 2025 could renew concerns about the grid’s ability to handle surging demand during extreme cold.
Rising Demand and Cold Weather Trends
Texas recently experienced its highest-ever winter electricity demand, peaking at over 78,400 megawatts on January 16, highlighting the growing strain on the grid during cold weather events. Coleman pointed to oceanic and atmospheric patterns that align with the conditions seen in early 2021, suggesting that similar challenges could lie ahead.

Notably, while Texas has seen an increase in extreme cold events—with five of the last eight winters logging significant cold spells—average winter temperatures remain generally warmer. Last winter, for instance, ranked as the 11th warmest since 1895.

Preparing for What’s Ahead
As the possibility of another severe winter looms, Texas’ energy infrastructure faces a critical test. ERCOT’s efforts to improve grid resilience will likely come under scrutiny, with residents and businesses watching closely to see how well the system can withstand potential cold snaps.
