A handful of bills have been introduced that seek to adapt to more frequent heat waves.

What are we going to do about the heat? As devastatingly hot as this summer has been — and it has broken records and likely killed thousands of Americans — next summer will almost certainly be worse. Will Congress act?
New federal legislation to attack the root of the problem by reducing carbon emissions isn’t on the table, thanks to Republican control of the House. But that doesn’t mean there’s zero chance of any kind of heat legislation emerging this year. Republicans have proven open to funding ideas like better hurricane forecasting, the streamlining of flood insurance claims, and more seawalls — all things that get lumped into the category of adaptation to extreme weather or resilience. Could something similar be possible for heat?
A handful of bills have been introduced — almost all by Democrats — that seek to adapt to heat in one way or another. Because adapting to hotter temperatures isn’t as simple as erecting new levies, all the legislation seeks in one way or another to ensure everyone has access to a cooler environment. That might mean giving people money to keep their air conditioners running, funding cooling centers, or building shade outside.
Here are the bills, from most reactive to most proactive:
1. The Extreme Heat Emergency Act: This bill would put heat waves on FEMA’s list of major disaster qualifying events — making funds available for cooling centers and additional personnel. Representative Ruben Gallego, a Democrat from Arizona, introduced the bill alongside Representatives Mark Amodei, a Republican from Nevada, and Sylvia Garcia, a Democrat from Texas..
It might have a better chance with Republicans than its counterparts because FEMA is familiar, says Bob Inglis, a former Republican congressman from South Carolina and the executive director of RepublicEn, a project of the Center for Climate Change Communication at George Mason University that seeks to use “conservative principles” to solve climate change. The agency “butters the bread in conservative districts” in Texas, Louisiana, and Florida when disaster strikes, Inglis explained.
The problem is that FEMA funding only arrives after a disaster has already taken place. Alex Flint, executive director of the right-leaning climate think tank Alliance for Market Solutions, referred to FEMA funding and emergency supplemental bills as “old tools.”
“We will see the need to address higher temperatures in the defense bill, transportation bill, farm bill,” he said. “But policymakers are only just starting to grapple with the near-term effects of this long-term crisis.”
“Things can get more expensive after the fact,” Amy Bailey, director of climate resilience and sustainability at the Center for Climate and Energy Solutions, told me.
2. The Heating and Cooling Relief Act: This bill, introduced by Massachusetts Senator Ed Markey and New York Representative Jamaal Bowman, both Democrats, would inject tens of billions of dollars into the Low Income Home Energy Assistance Program, which helps low-income families pay their utility bills. The bill would also increase funding for cooling assistance — but it also hasn’t attracted a single Republican cosponsor, consistent with the party’s wariness about extending government assistance to low-income Americans.
3. The SHADE Act: This bill would do what its name implies and fund the creation of shade to attack urban heat islands, especially in areas that are low-income or have historically experienced discrimination. The bill has attracted 55 cosponsors — all Democrats.
4. The Preventing HEAT Illness and Death Act: Of the options, this bill is the most wide-reaching. It calls for a study that would identify the gaps in what we know about extreme heat as well as the public facilities (read: schools and prisons) without air conditioning. It would also offer $100 million in financial assistance to communities that want to adapt to extreme heat — installing cool roofs, creating more urban forestry, or making a grid more resilient, as well as training on risk communications — with the condition that 40% of its funding goes towards communities that are low-income or have environmental justice concerns. And it also calls for similar interagency communication on extreme heat that already exists for hurricanes and floods.
“It’s a perfectly reasonable bill that’s aimed towards saving lives on the ground,” said Alice Nam, press secretary for Representative. Marilyn Strickland, a Democrat from Washington state and one of the bill’s House sponsors. “It doesn’t propose a one-size fits all solution.”
“We need the federal government to respond with the urgency these climate and public health crises demand,” sponsor Senator Ed Markey, Democrat of Massachusetts, wrote in a statement to Heatmap.
And interagency communication, Bailey added, would be an “incredible benefit” — helping communities access resources faster. Extreme climate events that cost more than $1 billion, she noted, happened on average every 18 days in 2022, so speed is key.
Markey introduced the same bill in 2021, which advanced out of the Senate Commerce Committee in a bipartisan vote. This year’s version doesn’t have a single Republican co-sponsor in the House — though its authors are actively looking for them, Nam said.
“It’s really hard to tell what is too big of a pill for Republicans to swallow,” she said.
Last Congress, the bill was introduced into the House Energy and Commerce Committee and the House Science, Space and Technology Committee — meaning that this time, either Representative Frank Lucas, Republican of Oklahoma, or Representative Cathy McMorris Rodgers, Republican of Washington state, would need to hear the bill, and Republicans on either of those committees would need to vote in its favor.
Inglis noted that Republicans would likely take issue with the fact that the bill relies on a comparatively narrow set of funds and grants, in addition to the possibility that it could add regulations to plans to adapt to heat. “Conservatives are right to say we don’t need a U.S. Department of Trees for cities,” Inglis said, noting that Republican members would likely prefer for cities to lead the charge themselves — though he added that that still often requires federal block grants.
But eventually, Flint said, Republicans — even in the House — will come around to the idea that the government should spend money to fund adaptation to climate change.
“Voters of all political persuasions are going to be impacted by fires, flooding, hurricanes, and politicians will have to respond,” he noted. “The climate doesn’t care about people’s politics and will change the lives of Republicans and Democrats alike.”

Talking with National Grid’s Matthew Satterwhite about his new report with S&P Global.
This week’s conversation is with Matthew Satterwhite, head of U.S. policy for National Grid. This week National Grid released a report in collaboration with S&P Global I found noteworthy amidst the data center backlash, asserting that building new transmission lines can potentially reduce consumer costs. I reached out asking if we could chat about how this argument leans into the fight over hyperscale infrastructure. I found our conversation illuminating and educational.
The following Q&A was lightly edited for clarity.
Why did you make this report?
It’s all focused on our customers. We’re always looking to find ways to make sure we can provide our service in the most affordable way possible, the most efficient way possible, and we always think of transmission, but it’s fallen out of favor recently. There’s so much demand with large loads, data centers, advanced manufacturing, reshoring. There’s such a need, and a lot of the debate has been focused on what we need on the generation side. We think transmission is an answer, as well.
We focused on what we have control over — since we’re in deregulated states, the only generation we’re doing is to help states reach their renewable goals. It’s a real page-turner. We really get to the core of everything.
Can we lower customer bills with transmission? This report actually showed us that’s a good investment and helps with the resource adequacy and the constraint problems we have in the Northeast. You can bring cheaper electricity in.
With respect to concerns for everyday consumers, how much do you feel like new transmission might alleviate ordinary Americans’ concerns about rising energy prices?
When you look at the demand that’s coming, the projection is that by 2035, we’ll have to add 45 gigawatts, currently. We’re on that path right now. Transmission alone isn’t going to meet that, but the question is, how do we temper that down? What do we do as National Grid to help alleviate the need for all that demand? Can we get that somewhere else rather than in the region by building generation? It's a different version of all of the above. It’s not a generation single answer or a transmission single answer. We think transmission is a big part of that.
This also allows you to bring in cleaner energy from other places. The more robust the network is, you can have energy in different places and bring that in. It replaces the need for some of the generation to be built and pays for itself by creating a cheaper return for customers adding this.
How much of the data center backlash is affecting your transmission project planning calculus? How is it changing what lines are built in the country?
We’re focused on how we can provide the cheapest service for our customers and physics. It’s science and long-term planning. We don’t have the luxury — we can’t follow, this month we’re thinking something, someone got mad, and so we’re thinking something else. We study a lot of science and physics to figure out how to build the grid.
Do you feel like the average Joe Schmoe American sees transmission as making their life less expensive and making their electricity more reliable?
I think there’s frustration and a lack of understanding about the industry overall. There’s fear of the unknown. Are data centers really driving everything that’s happening? That’s where I think, with reports like this, the benefit of it will be that people will read this and see there’s other things we can do to address the load that we need, something different than building a bunch of generation plants.
How do the question marks around whether data centers get built affect transmission planning? How much harder is the backlash making your job?
It’s a science question. Do we do a bunch of work and then nothing happens? That’s why states put their policies out. There’s multiple studies you go through with a region and with a utility. I think that’s one reason why you see states slowing down, to make sure the policy is in check so people don’t do work they don’t need to do. It’s about having the policy to make sure, if you’re studying something, you’re doing it with a purpose.
Plus more of the week’s biggest development fights.
1. Clark County, Nevada – The first data center approved on federal lands has hit a legal brick wall.
2. Jackson County, Missouri – We have yet another high-profile case of a city councilor losing their job over voting for a data center, and this one’s a doozy.
3. Utah – What’s it take for the Bureau of Land Management to approve a big transmission line for zero-emission energy generation these days? Geothermal, baby.
4. Huntsville, Alabama – You can’t even build a tiny battery storage facility in the middle of Alabama anymore.
Where temporary moratoria could happen next.
Brace yourself for more statewide data center moratoria.
So far there are only two full state-wide blocks on data center permits, in New York and Texas. At least fifteen states have moratorium legislation in the pipeline, but few if any of those bills stand a chance of becoming law in the short term. Here are five states, however, where a broad development pause may gain momentum in the next year or two — and all of them are crucial to watch this November.
If you blinked you may have missed it: New Hampshire Governor Kelly Ayotte, a Republican, said she wants to enact a statewide data center moratorium.
Ayotte first came out in support of a pause last month at a Rotary Club meeting, declaring, “It does not make any sense at all to site a data center in New Hampshire.” She also reportedly plans to include a moratorium proposal in her upcoming 2027 fiscal budget. New Hampshire’s legislative sessions occur in the first half of the year, so we won’t see action on a moratorium bill this fall. But Ayotte’s statements suggest the Granite State — which is controlled by the GOP — could pivot to a pause very soon.
New Hampshire has very few data centers. Like, almost none. Only two project fights exist in the Heatmap Pro database, both in Portsmouth, and each has been canceled amidst opposition. Ayotte’s remarks were prompted by the fight against a hyperscale project being studied in the small town of Bow at a former coal plant that closed in late 2025.
None of this should surprise anyone familiar with New England NIMBYs. A New Hampshire moratorium also makes sense given the state’s proximity to Maine, which almost had one of its own. Ayotte, who is up for re-election this year, is likely looking at the political fortunes of Governor Janet Mills and trying to avoid potholes ahead of a likely blue wave hitting her state.
This week, Arizona Attorney General Kris Mayes, a Democrat, came out in support of a statewide data center moratorium.
Mayes told Arizonans in a public statement on Monday that she wants to avoid undue strain on the electric grid and adding to the burden of water cuts led by the Trump administration. Phoenix, where opposition grows by the day, seems to be the primary reason. This shouldn’t in any way be a surprise given the backlash to these projects, which in Arizona’s case is rooted in legitimate water security concerns.
One of the first high-profile data center conflicts I ever learned about was in Arizona: Project Blue, which had to move on from the city of Tucson after officials voted it down last summer. That led Amazon to bail from the facility, though it’s still under development elsewhere on county land. Locals are deeply concerned about the water impacts.
Ordinarily an attorney general wouldn’t have any sway on legislative or executive policy, but the state is already quite receptive to restricting data center development. Governor Katie Hobbs has enacted a three-year pause on tax abatements for data centers, and in response to requests for comment on Mayes’ statement, has told media she’s working on more policies targeting the sector. Hobbs has said she will do more in the following legislative session, but it’s not clear what.
The real decisive action here is probably going to be legislation, and that will depend on the reception any moratorium finds with Republicans in the state legislature, which is typically split in this purple state. The Arizona GOP is quite pro-industry, and Mayes’ opponent in her race for re-election opposes restricting data center construction.
You really should get to know the name Cindy Holscher for the next two months.
Holscher, a state senator, won a surprise upset victory in the Democratic gubernatorial primary this year, and currently sits within a one-point margin of her Republican opponent. How’d she get the nom? By calling for a statewide data center moratorium. “It reminds me of when the automobile manufacturers had to put seatbelts into their cars,“ Holscher told MSNOW after she won the primary. “We as a people and as a state just need to make sure there are guardrails in place.”
Kansas politics are weird. The state is best known as a conservative ideological bastion that’s pro-business. Full Republican control of the Kansas government during the Obama era led to significant social services cuts most closely associated with former Governor Sam Brownback. But after that, Kansans seemed to like moderate Democratic governors, electing Laura Kelly in 2022. Kelly is now term limited out of office.
Kansas already has a colorful patchwork of local data center and renewable energy restrictions. Land use is a big deal in this agricultural behemoth. Should Holscher win in a blue wave year, she would have a mandate to enact a statewide moratorium. Still, Republicans control the legislature, and that’s unlikely to change. My major questions are, should Holscher win, would the GOP in state government listen to Holscher’s request? Or can she do this through the executive branch?
Politics nerds are obsessing over Ohio right now. There, Trump acolyte Vivek Ramaswamy is neck-and-neck in the polls for governor with a Democratic candidate who backs a “conditional” data center moratorium: Amy Acton.
What’s a conditional moratorium? It’s in the eye of the beholder, really. Technically speaking, Governor Josh Shapiro instituted a conditional moratorium in Pennsylvania, where data center projects cannot get permits unless they meet very specific standards set by the governor himself. Shapiro did it through executive action, but in this case, it’s unclear whether the moratorium will be codified through that process or through law.
Should Acton win — or if former Senator Sherrod Brown defeats sitting Senator Jon Husted in the U.S. Senate race — I anticipate major legislative action on data centers in Ohio. Republicans there have essentially permanent control of the state legislature, and they’ve historically been pro-data center. But the freakout over opposition to artificial intelligence and hyperscalers in the senate race specifically has spooked national Republicans, who think it provided the opening Brown needed to potentially win back his seat. Acton and Brown’s political fortunes appear to be wedded to one another, linked to a general angst in the American public.
Every top 5 list needs a wild card, and mine is Oklahoma.
Currently, there’s minimal risk of a data center moratorium. I might’ve had this state higher on my list had Gentner Drummond won the runoff for the GOP gubernatorial primary, given his proclivity to side with anti-renewables activists who also oppose data centers. Instead, likely future governor Mike Mazzei is running on a more moderate, Trump-friendly approach to data centers centered on maintaining industry growth while protecting ratepayers from new infrastructure costs. His opponent, Cyndi Munson, supports a one-year moratorium.
I consider Oklahoma’s odds of having a data center moratorium about equal to the chance of a statewide wind energy ban. Momentum for anti-wind legislation began in the state legislature, and I expect the same to happen with data centers. But unlike the wind industry, which has enormous power in the state, data centers are still a nascent industry. This is a place that may take about two or three years to manifest full cultural upheaval over these projects.
