What Can State Learn From Texas Crisis?
Power generators in Midwest built to withstand freezing weather, utilities say.
More than half a million Americans from Oregon to Virginia dealt with power outages Thursday as winter storms continued in parts of the country.
Earlier this week, Texas was hit particularly hard. Frigid temperatures caused demand for electricity to skyrocket, while also preventing the state — which is on its own electrical grid — from generating enough power. Homes have been without electricity, and burst pipes and low water pressure have caused their own problems.
“People are coming in hypothermic. They’re coming in with carbon monoxide poisoning, desperate to keep themselves and their kids warm,” she said.
In Rockport, which is three hours south of Houston, temperatures dipped well below freezing on Monday and Tuesday. On Wednesday, it was difficult to get gasoline, and food was scarce at the local grocery store. Fortunately, temperatures there are on the rise.
Wisconsin Utilities Say They’re Focused On Reliability
Demand for natural gas has increased amid the cold weather, but Alliant Energy expects its supply to meet the needs of its customers in Wisconsin and Iowa, said Director of Operations Matt Cole. The utility also provides energy through wind, solar and coal.
“This broad portfolio is purposeful and ensures that we’ve got a diversified approach. What that means is greater resiliency and reliability for our customers every single day,” Cole said.
Madison Gas and Electric Co. builds its equipment and infrastructure to withstand multiple days of 40-below weather, a spokesperson said.
And WEC Energy Group prepares for extreme cold and practices its response for severe weather events, said communications specialist Matt Cullen. Providing safe and reliable energy is the company’s priority, Cullen said. It’s also expanding its diverse mix of generation facilities, with a new solar park planned for Kenosha.
Still, severe weather can impact Wisconsin utilities. It occurs most commonly when a branch falls on a power line or an icy road sends a driver into a utility pole, Cullen said. Customers should always report outages, he said.
“Reporting outages to us is really key because it’s that first step in the process of us being able to send a crew out to the area, make the area safe if that’s needed, and then begin those repairs and restore service,” he explained.
It’s also a good idea to have an emergency kit that includes flashlights, blankets, water bottles, portable chargers and extra batteries, Cullen suggested.
A ‘Low-Probability, High-Impact’ Event
Demand for electricity goes up when temperatures drop, said Dr. Line Roald, an assistant professor of engineering at the University of Wisconsin-Madison. The surprising part of what happened in Texas was that so many generators — from nuclear and natural gas plants to wind turbines — stopped producing energy due to the freezing temperatures, she said.
In colder parts of the country, it’s easier to plan for high demand in winter, though northern states aren’t immune to natural gas shortages, Roald said. It’s also practical to invest in the type of infrastructure that allows generators to continue producing energy on frigid days.
What took place in Texas was a “low-probability, high-impact” event, Roald explained.
“Probably, this type of event wouldn’t be too bad in Wisconsin,” she said. “We already know we can live normally with colder temperatures, but the question here becomes what are those scenarios that we need to plan for that maybe we haven’t thought about.”
It can be a tough trade off, where success goes unnoticed, but failure makes headlines. Roald said had Texas power plants been built to withstand extreme cold, they probably wouldn’t be in the news.
“All we would have heard is that it’s really cold in Texas,” Roald said.
