SAN ANTONIO — Texans have experienced more major power outages in the past 20 years than residents of any other state, a new report shows, and the blackouts have become more frequent amid increasingly extreme weather in recent years.

Environmental advocacy group Climate Central analyzed outage notices filed with the U.S. Department of Energy to calculate the most blackout-prone states. In addition to its rankings, it found there were 64 percent more major power outages across the U.S. from 2011 to 2021 than in the decade from 2000 to 2010.

“As extreme weather events become more common and electrical infrastructure continues to age, the number of outages is only likely to increase,” the group said.

About 83 percent of all major outages — those impacting at least 50,000 customers — in the past 20 years were attributed to weather. Most of those were in the Southeast, followed by the Midwest and Northeast.
