In the face of a devastating heat wave, the rickety system has managed to keep ACs around the state running. How?
Texas’ uniquely isolated and deregulated electricity grid has been wobbling on the edge of rolling blackouts this week thanks to extreme heat throughout the state.
At least so far, the grid has survived, despite less wind than expected, some power plants going offline, and near-record levels of demand. It hasn’t been so lucky in the past. The state became a poster child for the risk that extreme weather can pose to electricity generation in 2021 when Winter Storm Uri led to massive and deadly blackouts.
With Texas still facing a potentially deadly combination of extreme weather, homes that rely on electricity for both heating and cooling, and an energy market that has historically underinvested and underemphasized resiliency and is disconnected from the rest of the country, how has the state managed to avoid devastating blackouts during this heat wave — and I can’t stress this enough — so far?
One big reason is that electricity generation hasn’t quite hit the record-breaking levels ERCOT, the grid operator, has feared.
On Tuesday, power peaked at just over 79,000 megawatts, just below the over 80,000 megawatts record demand last summer, despite temperatures at or near 100 degrees — and heat indices approaching an astonishing 120. ERCOT had forecasted a record-setting electricity consumption day, but actual electricity demand fell below its predictions for the late morning and the afternoon.
Highlighting the risk still confronting the state, ERCOT has forecast that demand for power Wednesday will break records though.
“It has been record or near-record heat in South Texas, not so much in North Texas. Even though the ERCOT electric grid is relatively small, it’s been big enough to move power around from where it’s needed less to needed more,” Texas A&M professor and state climatologist John Nielsen-Gammon told me in an email Tuesday afternoon. One big concern with Texas’ grid is that when the entire state is in need of power, it can’t import electricity from the rest of the country, but at least so far, intra-state transfers have been sufficient.
That could be because ERCOT did itself — and Texas — a massive favor by sending out a warning to Texans on Tuesday just asking them “to voluntarily reduce electric use, if safe to do so.”
These kind of informal requests to reduce power consumption at moments of high demand are not uncommon and can work — they’ve been used successfully in New York and California. They’ve even been used before in Texas during the summer, despite the state’s reputation for being more generation-than-conservation friendly compared to its big state peers.
When comparing the disaster in 2021 to today, it’s also helpful to note that a big reason the state struggled back then was large amounts of natural gas generation going offline due to poor winterization.
Summertime brings even higher electricity demand than the winter, but it tends not to pose the same threat to the grid, explained University of Texas researcher Joshua Rhodes.
“The vulnerability in the summer is that everyone has an air conditioner,” Rhodes said.
That same high heat that causes people to crank up their air conditioning also means that solar power tends to be more abundant at the same time. By the late afternoon Tuesday, solar was providing 14.5% of Texas’ electricity, operating at 90 percent of its summer capacity. Meanwhile natural gas was responsible for just over half of Texas’ electricity generation, but operating at 85 percent of its summer capacity.
“Whoever designed it such that solar energy output is high when it is hot outside was brilliant,” University of Texas professor of energy resources Michael Webber tweeted Tuesday afternoon.
Natural gas power plants can underperform due to high heat, Rhodes said, but the risk of catastrophic failure is lower. Texas also schedules power plant maintenance in order to ensure that plants are online during the highest demand portion of the year.
But while natural gas provides the bulk of Texas’ electricity, wind and solar play a substantial and growing role in the state’s power generation. When ERCOT requested that Texans voluntarily reduce power consumption, it cited “higher than normal” power plant outages as well as “low wind generation compared to historic performance during summer peak.”
Like much of the country, fossil-fuel-rich Texas is dependent on renewables to keep the lights (and AC) on. The head of the Public Utility Commission of Texas warned in May that “On the hottest days of summer, there is no longer enough on-demand dispatchable power generation to meet demand on the ERCOT system.”
According to ERCOT figures from Tuesday, the listed summer capacity of coal, nuclear, and natural gas would have fallen short of peak demand, let alone the record demand forecasted on Monday, so solar really has played an important role in keeping danger at bay — and, again, I can’t stress this enough — so far.
As might be expected in a conservative state with a massive energy industry, when it came time to address reliability issues following Uri and record breaking heat last summer, Texas’ elected officials chose to do so in a way that would favor more fossil generation, as opposed to energy efficiency or more extensive demand management. Governor Greg Abbott signed a slew of bills in its past legislative session, including a bill that would set up a program for billions of dollars worth of loans for new gas-fueled power plants, while vetoing a bill that would allow the state to update building codes due to a fight between the governor's mansion and the statehouse over property taxes.
But Texas remains a renewable powerhouse, and like renewable-heavy California with its “duck curve,” Texas faces its own late-day energy crunch, in its case a so-called “armadillo curve,” when solar power drops out of the grid even as demand remains high thanks to continued high temperatures.
At least so far this week, the grid has held up. But summer has only just begun. The National Weather Service projects that “Excessive Heat Warnings may return” in parts of Texas this weekend and early next week. And ERCOT plans every year around power demand peaking in August.

Unlike just about every other car sales event, this one has a real — congressionally mandated — end date.
Car salespeople, like all salespeople, love to project a sense of urgency. You know the familiar seasonal rhythm of the TV commercial: Toyotathon is on now — but hurry in, because these deals won’t last. The end of the discount is, of course, an arbitrary deadline invented to juice that month’s sales figures; there’ll be another sale soon.
But in the electric vehicle market there’s about to be a fire sale, and this time it really is a race against the clock.
Federal incentives for EVs and EV equipment were critically endangered the moment Donald Trump won the 2024 presidential election. Now, with the passage of the omnibus budget reconciliation bill on the Fourth of July, they have a hard expiration date. Most importantly, the $7,500 federal tax credit for an EV purchase is dead after September 30. Drivers who might want to go electric and dealerships and car companies eager to unload EVs are suddenly in a furor to get deals done before the calendar turns to October.
The impending end of the tax credit has already become a sales pitch. Tesla, faced with sagging sales numbers thanks in part to Elon Musk’s misadventures in the Trump administration, has been sending a steady slog of emails trying to convince me to replace my just-paid-off Model 3 with another one. The brand didn’t take long to turn the impending EV gloom into a short-term sales opportunity. “Order soon to get your $7,500,” declared an email blast sent just days after Trump signed the bill.
On Reddit, the general manager of a Mississippi dealership posted to the community devoted to the Ioniq 9, Hyundai’s new three-row all-electric SUV, to appeal to anyone who might be interested in one of the three models that just appeared on their lot. It’s an unusual strategy, a local dealer seeking out a nationwide group of enthusiasts just to move a trio of vehicles. But it’s not hard to see the economic writing on the wall.
The Ioniq 9 is a cool and capable vehicle, but one that starts at $59,000 in its most basic form and quickly rises into the $60,000s and $70,000s with fancier versions. Even with the discount, the Ioniq 9 costs far more than many of the more affordable gas-powered three-row crossovers. And now the vehicle has come down with a serious case of unlucky timing, with deliveries beginning this summer just ahead of the incentive’s disappearance. As of October 1, the EV could become an albatross that nobody in suburban Memphis wants to drive off the lot.
Over the past year, Ford has offered the Ford Power Promise, an excellent deal that throws in a free home charger plus the cost of installation to anyone who buys a new EV. That deal was supposed to expire this summer. But the Detroit giant has extended its offer until — surprise — Sept. 30, in the hopes of enticing a wave of buyers while the getting is good.
This isn’t the first time EV-makers have been through such a deadline crunch. When the $7,500 federal tax credit for EV purchases first started in 2010, the law was written so that the benefit phased out over time once a car company passed a particular sales threshold. By the time I bought my EV in the spring of 2019, for example, Tesla had already sold so many vehicles that its tax credit was halved from $7,500 to $3,750. We had to rush to take delivery in the last few days of June as the benefit was slated to fall again, to $1,875, on July 1, before it disappeared completely in 2020.
The Inflation Reduction Act passed under President Biden not only reinstated the $7,500 credit but also took away the gradual decline of the benefit; it was supposed to stick around, in full, until 2032. But despite Trump’s on-again, off-again bromance with Elon Musk, the president followed through on his long-term antagonistic rhetoric against EVs by repealing the benefit as part of this month’s disastrous big bill.
Trump, despite his best efforts, won’t kill the EV. The electric horse has simply left the barn — the world has come too far and seen too much of what electrification has to offer to turn back just because the current U.S. president wants it to. But the end of the EV tax credit (until a different regime comes into power, at least) seriously imperils the economic math that allowed EV sales to rise steadily over the past few years.
As a result, now might be the best time for a long time to buy or lease an electric vehicle, with remarkably low lease payments to be found on great EVs like the Hyundai Ioniq 5 and Chevy Equinox. Once the tax breaks are gone, lease deals (which got lots of drivers into EVs without them having to worry about long-term ownership questions) are likely to grow less enticing. EVs that would have been cost-competitive with gasoline counterparts when the tax credits taken into account suddenly aren’t.
Plenty of drivers will continue to choose electric even at a premium price because it’s a better product, sure. But hopes of reaching many more budget-first buyers have taken a serious hit. It could be a dream summer to buy an EV, but we’re all going to wake up when September ends.
On the NRC, energy in Pennsylvania, and Meta AI
Current conditions: Air quality alerts will remain in place in Chicago through Tuesday evening due to smoke from Canadian wildfires • There is a high risk of a tropical depression forming in the Gulf this week • The rain is clearing on the eastern seaboard after 2.64 inches fell in New York’s Central Park on Monday, breaking the record for July 14 set in 1908.
The Trump administration is putting pressure on the Nuclear Regulatory Commission to “rubber stamp” all new reactors, Politico reports based on conversations with three people at the May meeting where the expectation was relayed. The directive to the NRC’s top staff came from Adam Blake, a representative of the Department of Government Efficiency, who apparently used the term “rubber stamp” specifically to describe the function of the independent agency. NRC’s “secondary assessment” of the safety of new nuclear projects would be a “foregone conclusion” following approval by the Department of Energy or the Pentagon, NRC officials were made to believe, per Politico.
A spokesperson for the NRC pointed to President Trump’s recent executive order aiming to quadruple U.S. nuclear power by 2050 in response to Politico’s reporting. Skeptics, however, have expressed concern over the White House’s influence on the NRC, which is meant to operate independently, as well as potential safety lapses that might result from the 18-month deadline for reviewing new reactors established in the order.
President Trump and Republican Senator Dave McCormick of Pennsylvania will announce a $70 million “AI and energy investment” in the Keystone State at the inaugural Pennsylvania Energy and Innovation Summit today in Pittsburgh. The event is meant to focus on the development of emerging energy technologies. Organizers said that more than 60 CEOs, including executives from ExxonMobil, Chevron, BlackRock, and Palantir, will be in attendance at the event hosted by Carnegie Mellon University. BlackRock is expected to announce a $25 billion investment in a “data-center and energy infrastructure development in Northeast Pennsylvania, along with a joint venture for increased power generation” at the event, Axios reports.
Ahead of the summit, critics slammed the event as a “moral failure,” with student protests expected throughout the day. Paulina Jaramillo, a professor of engineering and public policy at Carnegie Mellon, wrote on Bluesky that the summit was a “slap in the face to real clean energy researchers,” and that there is “nothing innovative about propping up the fossil fuel industry.” “History will judge institutions that chose short-term gain over moral clarity during this critical moment for climate action and scientific integrity,” she went on.
On Monday, Meta founder and CEO Mark Zuckerberg confirmed on Threads that the company aims to become “the first lab to bring a 1GW+ supercluster online” — an ambitious goal that will require the extensive development of new gas infrastructure, my colleague Matthew Zeitlin reports. The first gigawatt-level project, an Ohio data center called Prometheus, will be powered by Meta’s own natural gas infrastructure, with the natural gas company Williams reportedly building two 200-megawatt facilities for the project in Ohio. The buildout for Prometheus is in addition to another Meta project in Northeast Louisiana, Hyperion, that Zuckerberg said Monday could eventually be as large as 5 gigawatts. “To get a sense of the scale we’re talking about, a new, large nuclear reactor has about a gigawatt of capacity, while a newly built natural gas plant could supply only around 500 megawatts,” Matthew writes.

Electric vehicle sales are currently on track to outpace gasoline car sales in China this year, Bloomberg reports. In the first six months of 2025, new battery-electric, plug-in hybrid, and extended-range electric cars accounted for 5.5 million vehicles sold in the country (compared to 5.4 million sales of new gasoline cars), and are projected to top 16 million before the end of December — both of which put EVs a hair over their combustion-powered competitors.
By contrast, battery-electric cars only accounted for 28% of new-car sales in China last year, per the nation’s Passenger Car Association. But “sales this year have been spurred by the extension of a trade-in subsidy” as well as the nation’s expansive electrified lineup, including “several budget options” like BYD’s Seagull, Bloomberg writes. “China is the only large market where EVs are on average cheaper to buy than comparable combustion cars,” BloombergNEF reported last month.
Window heat pumps are an extremely promising answer to the conundrum of decarbonizing large apartment buildings, a new report by the nonprofit American Council for an Energy-Efficient Economy has found. Previously, research on heat pumps had primarily focused on their advantages for single-family homes, while the process of retrofitting larger steam- and hot-water-heated apartment buildings remained difficult and expensive, my colleague Emily Pontecorvo explains. But while apartment residents used to have to wait for their building to either install a large central heat pump system for the whole structure, or else rely on a more involved “mini-split” system, newer technologies like window heat pumps proved to be one of the most cost-effective solutions in ACEEE’s report with an average installation cost of $9,300 per apartment. “That’s significantly higher than the estimated $1,200 per apartment cost of a new boiler, but much lower than the $14,000 to $20,000 per apartment price tag of the other heat pump variations,” Emily writes, adding that the report also found window heat pumps may be “the cheapest to operate, with a life cycle cost of about $14,500, compared to $22,000 to $30,000 for boilers using biodiesel or biogas or other heat pump options.” Read Emily’s full report here.
California was powered by two-thirds clean energy in 2023 — the latest year data is available — making it the “largest economy in the world to achieve this milestone,” Governor Gavin Newsom’s office announced this week.
CEO Mark Zuckerberg confirmed the company’s expanding ambitions in a Threads post on Monday.
Meta is going big to power its ever-expanding artificial intelligence ambitions. It’s not just spending hundreds of millions of dollars luring engineers and executives from other top AI labs (including reportedly hundreds of millions of dollars for one engineer alone), but also investing hundreds of billions of dollars for data centers at the multi-gigawatt scale.
“Meta is on track to be the first lab to bring a 1GW+ supercluster online,” Meta founder and chief executive Mark Zuckerberg wrote on the company’s Threads platform Monday, confirming a recent report by the semiconductor and artificial intelligence research service Semianalysis that
That first gigawatt-level project, Semianalysis wrote, will be a data center in New Albany, Ohio, called Prometheus, due to be online in 2026, Ashley Settle, a Meta spokesperson, confirmed to me. Ohio — and New Albany specifically — is the home of several large data center projects, including an existing Meta facility.
At the end of last year, Zuckerberg said that a datacenter project in Northeast Louisiana, now publicly known as Hyperion, would take 2 gigawatts of electricity; in his post on Monday, he said it could eventually be as large as 5 gigawatts. To get a sense of the scale we’re talking about, a new, large nuclear reactor has about a gigawatt of capacity, while a newly built natural gas plant could supply only around 500 megawatts.
As one could perhaps infer from the fact that their size is quoted in gigawatts instead of square feet or number of GPUs, whether or not these data centers get built comes down to the ability to power them.
Citing information from the natural gas company Williams, Semianalysis reported that Meta “went full Elon mode” for the New Albany datacenter, i.e. is installed its own natural gas infrastructure. Specifically, Williams is building two 200-megawatt facilities, according to the gas developer and Semianalysis, for the Ohio project. (Williams did not immediately respond to a Heatmap request for comment.)
Does this mean Meta is violating its commitments to reach net zero? While the data center buildout may make those goals more difficult to achieve, Meta is still investing in new renewables even as it’s also bringing new gas online. Late last month, the company announced that it was procuring almost 800 new megawatts of renewables from projects to be built by Invenergy, including over 400 megawatts of solar in Ohio, roughly matching the on-site generation from the Prometheus project.
But there’s more to a data center’s climate footprint than what a big tech company does — or does not — build on site.
The Louisiana project, Hyperion, will also be served by new natural gas and renewables added to the grid. Entergy, the local utility, has proposed 1.5 gigawatts of natural gas generation near the Meta site and over 2 gigawatts of new natural gas in total, with another plant in the southern part of the state to help balance the addition of significant new load. In December, when the data center was announced, Meta said that it planned to “bring at least 1,500 megawatts of new renewable energy to the grid.” Entergy did not immediately respond to a Heatmap request for comment on its plans for the Hyperion project.
“Meta Superintelligence Labs will have industry-leading levels of compute and by far the greatest compute per researcher. I'm looking forward to working with the top researchers to advance the frontier!” Zuckerberg wrote.
