What Would It Take to Eliminate Storm-Related Power Outages?
Many in the Southeast still lack power during a dangerous cold snap. Experts say a few changes could make these outages less likely.

Hundreds of thousands of households, mostly in the Southeast United States, were without power when a dangerous cold snap hit this week, just days after the previous weekend’s winter storm buffeted large swathes of the country. Officials in several of the affected states have warned that these outages could linger for some time—in Mississippi, one emergency management coordinator told CNN that they might last “weeks, not days.”
Power outages during severe weather events are increasingly common. And they can easily be fatal, particularly when paired with extreme temperatures. What would it take to at least reduce the frequency of these outages, even as the severe weather driving them increases?
“There are several points of failure that lead to these kinds of widespread power outages,” Gudrun Thompson, senior attorney and energy program leader at the Southern Environmental Law Center, told me by phone. She pointed not just to the most recent storm but also to Winter Storm Elliott, which hit the Southeast hard in 2022, and Winter Storm Uri, which devastated Texas in 2021.
Getting electricity into homes happens in a few stages: It begins with power generation, then transmission (where it goes to substations), and finally distribution to the homes themselves. Here, the amount of power demand also plays a role. “Each of these need to be tackled, and some of the solutions won’t address all three of these,” said Adam Kurland, a federal energy attorney with the Environmental Defense Fund.
But both Thompson and Kurland pointed to a few things that could make a difference. “On the supply side, the biggest thing is just having a portfolio of diverse resources,” Kurland said. Renewables aren’t just good from a climate and environment perspective, he said, “they are also usually the most reliable during extreme weather events, and that’s been proven out by a number of studies that have found that both gas and coal have resulted in bottlenecks during extreme weather events.”
That’s particularly true in some of the regions suffering from outages this week. “You’ve got this legacy power system where the electric grid is still in this very twentieth-century model of big central station power plants,” said Thompson. “You’ve still got coal plants running in the South, you’ve got some nuclear plants, you’ve got a lot of new and old gas plants.” And “in some of these winter storms, we’ve literally seen these piles of coal freeze, so they couldn’t run the coal-fired plants.”
Gas supply networks are similarly vulnerable, and were a major factor in the Texas outages in 2021. Initial analysis from the energy and climate policy firm Energy Innovation suggests gas generation within PJM Interconnection—the country’s largest grid operator, serving over 65 million people across the mid-Atlantic to the upper South and Midwest—fell by 10 gigawatts during this most recent storm.
This contradicts everything that conservative politicians, in particular, tend to say in the wake of these events—certainly after the Texas outages in 2021. “I often get asked by reporters, ‘What do you say to what the electric utility is saying about how this winter storm event just proves they need more gas?’” Thompson said. “It’s a false narrative. Clean energy resources are more reliable, more affordable, less risky for consumers, when you kind of put them all together as a portfolio. You can’t rely on any one source, so you’ll hear fossil industry apologists saying, ‘Well, the sun doesn’t always shine, the wind doesn’t always blow.’ That’s true,” she said, but no one’s advocating relying on a single source.
And that points to another thing that could be done to eliminate these outages: a more interconnected grid. This was one of the main factors in 2021 in Texas, Kurland noted. “Texas’s power grid, ERCOT, is primarily islanded from the rest of the United States, so there weren’t a lot of connections there to be able to bring power into Texas during that storm.” If the goal is to build resilience to severe weather events, we need “an electrical grid that’s bigger than the weather,” Kurland said. With better transmission lines connecting different regions, it won’t matter if the sun isn’t shining or the wind isn’t blowing or severe cold is kneecapping fossil fuel generation in a particular location, because “you’re now able to dispatch power from one side of the United States to the other.”
Microgrids tied into the main grid, as well as better power storage, could also play a role. And then there’s the option of burying power lines, which would address the problem not only of the lines sagging under ice in the winter but also of stray sparks causing wildfires in other seasons. This isn’t feasible everywhere, Kurland emphasized, pointing to water tables and local geology. But even for such inhospitable locales, there are different, more advanced types of wires that are less vulnerable to sagging and the like. “There are some incentives that the federal government and the states can apply to be able to unlock those types of advanced technologies on the transmission system.”
When it comes to federal incentives, though, both Kurland and Thompson noted that a lot of the policies that could make households and the electrical grid less vulnerable in severe weather have been recently reversed, or the associated funds delayed. That’s true not just for, say, offshore wind projects but also for the weatherization programs that could both help reduce strain on the grid during cold snaps and help people survive brief outages when they occur. “As of last month, there were still a number of states trying to get that funding for cold snaps and extreme weather events like this,” said Kurland. He pointed to funds already designated to states via the Weatherization Assistance Program, slated to be released in June 2025, which still hadn’t arrived as of late December. Under the Trump administration, the Department of Energy has proposed scrapping the program altogether.
The entire grid feels the effect when homes aren’t weatherized, Kurland said. Weatherization is “one way that you can reduce that demand so there isn’t a big draw on the system.” If homes are drawing a large amount of energy, it can actually prolong outages. “When you have all the customers with the thermostats turned all the way up waiting for the power to come on, that can just trip that system again.”
Thompson also pointed to the Trump Environmental Protection Agency “unlawfully” canceling grants that had already been awarded for community solar programs and similar projects, in the Southern states where she works. “The Trump administration, even though they say they have this energy affordability agenda, is actually working to undermine successful policies and programs that would actually help households to afford their electricity bills,” Thompson said.

What I’m Reading
Time for some courage in the climate fight, too
I’ve been reading a lot of good essays from climate writers watching and troubled by the events in Minnesota in the last few weeks. Emily Atkin’s essay, over on Heated, is definitely worth your time, as is Bill McKibben’s reflection on just how wrong politicians have been, time and time again, when guessing what ordinary people care about.
… it’s not just the Trump administration that those brave people faced down, it’s the pundit class too, who insisted over and over that progressives should avoid talking about immigration because it wasn’t politically popular. The other subject we’ve been told to sideline is “climate change,” for fear of offending voters more interested in “affordability.” (Former energy secretary Jennifer Granholm told an industry audience Monday that “on Maslow’s hierarchy of human needs, climate does not rise as much as how much I’m paying for my electricity bill,” which is one of those things that sounds clever until you meet someone who lost their home to a wildfire.)
I actually have no problem with the advice to focus on electric bills—as I wrote a couple of weeks ago, I think affordability, especially of electricity, is an issue that helps both elect Democrats and reduce carbon emissions, since anyone interested in the cost of power is going to be building sun and wind. But I also don’t think that talking about global warming is a mistake—most Americans, polls show, understand the nature of the crisis, and want action to stem it. It isn’t the single most salient issue because all of us live in this particular moment (and in this particular moment the fact that federal agents are executing citizens who dare to take cellphone pictures of them is definitely the most salient issue) but it is nonetheless a net plus for politicians, especially in blue states.
