How freezing rain, tree-lined neighborhoods and above-ground power lines prolonged Austin power outages

At a news conference on Feb. 2, Elton Richards, Austin Energy’s vice president of field operations, said that although crews were on call on the morning of Feb.1, the storm was worse than expected. The weather forecast called for a quarter-inch of ice but as conditions worsened three-quarters of an inch accumulated.

“I just want customers to know we didn’t get blindsided. We do prepare for you guys and we did the best that we could on this one,” Richards said. “We got the crews here as fast as we could.”

Half an inch of ice on trees can mean the difference between limbs staying up or falling and taking power lines down with them. Ice can increase the weight of tree branches up to 30 times, according to Kerri Dunn, a communications manager for electricity provider Oncor. This becomes a larger issue when it comes to live oaks and evergreen trees that keep their leaves throughout the winter, collecting more ice than trees that shed their leaves in the fall.

Austin officials said the sheer number of downed trees, power lines and electricity poles — and the complicated task of making repairs — obstructed efforts to quickly restore power for tens of thousands.

“I’m sorry for how long this is taking,” Austin Energy general manager Jackie Sargent said at a press conference.

Much of Texas’ infrastructure was not built to sustain such extreme cold weather. And local governments historically have not prepared for winter weather — in large part due to the costs. Experts said cities and states across the U.S. must rethink their winter weather preparedness. That can include burying power lines, redeploying emergency response units and keeping trees trimmed,

“When we talk about adaptation, when we talk about resilience, what it means is that day to day, it costs more money to do that,” said Jeffrey Schlegelmilch, director of the National Center for Disaster Preparedness at Columbia University. “Now, it saves it in the long run. It saves it both in terms of economic loss as well as lives and livelihoods. But that [cost] is unavoidable.”

The 2023 outages differed from Winter Storm Uri. During that 2021 storm, the state’s electric grid nearly collapsed due to imbalances in electricity demand and power supply amid subfreezing temperatures across a large swath of the state. Still, the weather in 2023 ultimately caused major disruptions and closures.

“One thing Uri showed us is how vulnerable we are to any weather event that’s even a little bit outside of our normal operating conditions,” said Andrew Dessler, a climate scientist and the director for the Texas Center for Climate Studies at Texas A&M University. “Just a few degrees outside of that, and things go to hell very quickly.”

This year’s storm and subsequent prolonged power outages suggested little was done to fix city emergency communications systems after the 2021 winter storm. Austin Energy customers did not receive communications about when their power would be restored — or that they should prepare for days without electricity — until many had gone two days without. Austin Energy originally said power would be restored by 6 p.m. Feb. 3. But then Austin Energy said it could no longer promise when electricity would be fully restored. Austin Mayor Kirk Watson and Austin Energy officials took more than 24 hours after customers began losing power to hold their first press conference. On Feb. 5, Austin Energy said some customers wouldn’t have power back until Feb. 12 — or maybe later.

“By having a black hole in communications, unfortunately, the city of Austin has set themselves up for a narrative that they can’t deliver on the services,” said Steven Pedigo, the director of the University of Texas at Austin’s LBJ Urban Lab, which focuses on urban policy.

Parents around the Austin area faced an added challenge of finding places to keep their children warm and occupied when schools were closed for most of the week. Jennifer Parker and Justin Havird spent their Saturday looking for places to go to escape their powerless home with their two small children, Arlo and Vernon, ages 5 and 2.

“We woke up and started hunting for warm places to go,” Havird said. The day started with a trip to Whole Foods for breakfast, then a playground stop to give the kids some exercise time outside and finally a library visit for another distraction.

As the days without electricity persisted, Austinites stepped up to help their friends and neighbors — from sharing hand warmers and bringing by warm meals to loaning out chainsaws for tree removals.

After days of freezing rain, icy roads and power outages, many Texans were reminded of the power grid disaster from 2021. Some experts worry these winter crises can be damaging to people’s mental health.

Luz Maria Garcini, a licensed clinical psychologist and assistant professor at Rice University, said weather events over the past couple years have been traumatic for Texans.

“The loss of control and autonomy in their environment leads to anxiety,” Garcini said. “This sustained anxiety leads to depression because you get exhausted and people start isolating.”
