Senator Martin Heinrich’s bill, which makes it easier to connect new power plants to the grid, is an encouraging sign for bipartisan permitting reform.

An important part of a bipartisan permitting reform deal may be falling into place.
Senator Martin Heinrich of New Mexico introduced a bill on Thursday that would make it easier for new power plants to hook up to electricity markets across the country.
The legislation, which applies to all types of generation, would allow new power plants to connect to the grid without waiting for the arduous technical studies — and without paying the exorbitant equipment upgrade fees — now required in much of the country.
Instead, the bill would let power plants opt into a much faster safety study and offer what it cheekily dubs “basic access service for energy-only delivery” — that is, BASED service — to the local electricity market.
A similar approach is already used in Texas, which has added more new generation than any other U.S. power market in recent years. In effect, Heinrich hopes to bring that cheaper, faster, and more laissez-faire method to the rest of the country.
“As electricity demand grows, we need to find better, faster ways to add more affordable, reliable power to the grid,” Heinrich said in a statement. “Right now, unnecessary delays are slowing projects that could help lower energy costs and deliver the low-cost energy we need.”
Outside experts have pushed for wider adoption of Texas’s approach, which is dubbed “connect and manage,” for some time. Although Heinrich’s proposal would apply to all kinds of power plants, Texas has been particularly successful at bringing new solar, battery, and natural gas power plants online in recent years — and it has done so while keeping connection costs lower than other markets.
“We’re seeing the success of the free market in Texas,” Sarah Toth Kotwiss, an electricity researcher at the energy and climate think tank RMI, told me, noting the state has added far more generation in recent years than much bigger and more populous U.S. grid zones. “They’re leading the way, and replicating that free market attitude could go a long way in the rest of the U.S.”
More broadly, the proposal is the kind of legislation that would slot into the bipartisan permitting package expected later this year — and as soon as next month. Heinrich’s proposal may be a sign that the senator, the ranking Democratic member of the natural resources committee, takes the prospect of reaching a deal seriously.
Across much of the country, a new power plant can only connect to the power grid after the local grid operator completes what’s called an “interconnection study” — an intensive technical account of how that new plant will affect the overall system.
These studies examine a slew of worst-case scenarios, simulating how the plant would behave at full capacity under extremely congested grid conditions, such as during a heat wave. The new plant’s developer is then required to pay for the grid and transmission line upgrades that would allow their project to run at full blast at those moments of maximum stress.
In theory, that approach maximizes the amount of money a developer can make on a new power plant. But because the grid is a big, interconnected system, that method can cause long delays and rippling costs in practice. In one case, a new 300-megawatt plant in North Dakota near the Canadian border could not start operating until it paid nearly $3 million to upgrade power lines and transformers in Missouri — more than 1,000 miles away.
And because interconnection studies try to model a proposed power plant’s influence on the power grid for years into the future, a single cancellation can have a cascading effect. When a power plant pulls out of the interconnection queue, every project in line behind it sometimes needs to be studied again, causing delays and costs to spiral even further.
In one famous example, a solar and battery plant in Maryland was initially told that it needed to pay for $1.25 million to connect to the local grid. But after a series of cancellations and new rounds of study, that figure was revised — to nearly $72 million. The solar project got shelved.
While interconnection queues used to be relatively quick, the process of hooking up a new power plant to the grid can now regularly take eight years, Kotwiss said.
As I discussed with the electricity researchers Tyler Norris and Claire Waymer on Heatmap’s podcast Shift Key in 2024, these lengthening wait times have changed how power plant developers behave. Many developers now “spam the queue,” filing study requests for any project that they could ever conceivably want to build. That has led delays to spiral even further.
The end result of all this spamming is that the total capacity of power plants asking to connect to the grid now exceeds the size of the U.S. grid itself. At the end of 2025, more than 2,000 gigawatts of new generation or storage projects were waiting in interconnection queues, according to the Lawrence Berkeley National Lab. The country’s operating power plant fleet is only about 1,400 gigawatts.
To be clear, most of those proposed projects will never be built — they are hypothetical queries submitted by developers who are trying to claim a place in line. Yet even switching on a small set of plants could transform the power grid.
These long wait times aren’t the norm in Texas. In the Lone Star state, it takes less than four years to bring a new plant online.
That’s because new power plants in Texas can hook up to the grid — and start generating power — as soon as the local grid operator completes a more rudimentary engineering and safety study. Then during moments of peak grid congestion, power plants must curtail their own generation, reducing their electricity production to the level that the overall grid can support. While this means that a given solar farm or natural gas plant might not run at full bore all the time, the overall approach gets that plant up and running much sooner, allowing it to sell energy into the grid during most of the year.
Heinrich’s law would order electricity markets and grid operators to make this faster option available to new power plants across the country. It would let power plants opt into receiving a much simpler and faster study, one that checks only that adding the new power plant will be safe for the immediate grid.
A power plant that opts into the new BASED service would still have the option of entering the traditional interconnection queue. Doing so would let it eventually increase its operation over time, paying for grid upgrades so that it can participate in capacity markets and other auctions.
Expanding Texas’s approach to other states could help cut costs for electricity consumers by bringing more energy onto the market faster, Kotwiss said. Even in complicated power markets that include additional auctions — for capacity, for instance, or reliability — energy still makes up most wholesale costs.
It could also help ease the strains on the grid — especially in congested regions like the Mid-Atlantic — caused by artificial intelligence data centers and new factories.
The Texas-inspired technique could help the solar and battery industries, because it keeps a given project’s upfront expenses low and allows those technologies’ low costs to dominate their economics. Solar has boomed in Texas in recent years, and the state now has more utility-scale solar installed than California does.
But the BASED approach would likely help natural gas plants and other forms of newer, cheaper generation, too, because it strengthens new entrants as compared to incumbents. Jacob Mays, a Cornell engineering professor, has studied how slow and wonky interconnection queues can prevent electricity markets from functioning well. The existing interconnection approach used in most of the country “amounts to a significant barrier on new entry to new generation,” he told me, and it has “some anticompetitive impacts.”
Heinrich has said that he plans on introducing more electricity system reforms soon, including a bill to push utilities to adopt technologies that get more capacity out of their existing equipment.
I think it’s an encouraging sign for permitting reform advocates that ranking Senate Democrats are advancing these kinds of technology-neutral power market bills. An eventual deal will likely ultimately rest on Democrats’ willingness to support policy like this — and whether they can strike a deal with Republicans to rewrite parts of long-standing environmental or permitting laws, including the National Historic Preservation Act and Clean Water Act.
But just as importantly, it will depend on Republicans — and the White House — reining in President Trump’s powers to kill energy projects by fiat. With this bill, Democrats are suggesting they’re willing to be, well, a little BASED. Whether the president will join them remains to be seen.

Many nonprofits representing the environmental and climate movement are split.
This is Heatmap Daily, an evening digest written by our executive editor.
It’s now been just over a week since a gang of four bipartisan senators released the Bipartisan American Affordability and Jobs Act, or BAAJA. The permitting reform proposal would make too many changes to federal law to summarize cleanly here — read our explainer for that — but suffice it to say it creates a messy group of winners and losers. Utilities, data centers, and the Trump administration would lose; electricity ratepayers, clean energy companies, long-distance transmission lines, and natural gas pipeline builders win. (As would geothermal startups, virtual power plant providers, and a few other climate tech subsectors that my colleague Katie Brigham recently detailed.)
In the ensuing week since its release, we’ve gotten a better sense of the battle lines over the bill. The hardhat unions largely support the proposal (although the International Brotherhood of Electrical Workers, which is often aligned with utility executives, has stayed notably silent on it.) Clean energy trade groups, such as the American Clean Power Association, back it, too, as do fossil fuel lobbying groups, such as the American Petroleum Institute.
Groups representing the environmental and climate movement are more split, and some of the most influential nonprofits have yet to render a verdict. Earlier today, the Sierra Club published its first take on the proposal, which it described as a “hard look” at the bill. The Natural Resources Defense Council asked its own “hard questions” last Friday. Neither document rejects the proposal outright, although both are critical, and both suggest that future statements are coming.
To some degree, the statements say what you might expect: The groups like all the parts of the compromise that Democrats fought for (such as those that will encourage transmission) and dislike what Republicans wanted (such as those that will ease some pipeline permitting). That is what a compromise means — and for congressional procedure reasons too tedious to explain here, permitting reform will likely always need to be passed as a bipartisan compromise, because it will always need to overcome a 60-vote Senate filibuster.
The Sierra Club’s assessment divides the bill into “green flags,” which will make “long-overdue changes to protect consumers and level the playing field for proposed transmission,” such as by making it easier to plan long-distance power lines, protect ratepayers from utility and data center freeloading, and clarify who in the government can approve power lines. It also names four “red flags,” including the “hollowing out” of court authority over some permits, the removal of a Clean Water Act provision that lets governors block pipelines and power lines, and the option to delegate partial Endangered Species Act enforcement to state governments.
This is a helpful scheme, and I hope the Sierra Club continues using it. But I think it would be a mistake to analyze the bill solely through this metric, because it implicitly assumes we are starting from a neutral baseline — or that every additional “unit” of policy support, so to speak, helps an insurgent industry as much as it might aid an incumbent industry. To be clear: Although I’ve endorsed the idea of permitting reform in the past, I’ve been careful not to endorse or reject this particular permitting bill yet; I hope to write a more comprehensive take on this legislation — and whether I think it’s a good idea — before senators ultimately vote on it.
So for now, let me say that I think everyone should keep in mind that the baseline around U.S. energy permitting is, in fact, not neutral today. By this, I do not merely mean that natural gas pipelines already have a one-stop shop for federal permits, but transmission developers have to go hat in hand to every state government; nor that fracking is already carved out from some federal environmental review laws, but enhanced geothermal technology isn’t.
The mismatch goes deeper than that. Many of the discussions of the bill that I’ve seen seem to fear that the United States might witness some enormous and unprecedented fossil fuel buildout were the bill to pass. But make no mistake: We are already witnessing such a buildout. The United States is slated to add more than 60 gigawatts of new natural gas generation capacity by 2030 under its existing laws.
The existing system of laws, regulations, and procedures is failing to avert an enormous fossil fuel buildout. The existing system has proven itself completely inadequate to manage an era of electricity demand growth and the data center boom without surging fossil demand and sky-rocketing electricity prices. The existing system of laws is pushing hyperscalers and developers to burn natural gas on site, often through rudimentary jet engines.
And the existing system of laws has shown that fossil fuel consumers will go to great lengths to move and obtain fossil fuels, even when dedicated transport options like pipelines are not available. I’ve heard fears that the permitting bill will make it easier to build natural gas pipelines. But pipelines, to a dedicated artificial intelligence customer, are no constraint: Oracle is now delivering natural gas to some of its data centers by truck when pipeline capacity isn’t available.
There may be reasons for green groups to reject this deal. (And there may be reasons for Democratic lawmakers to support it anyway, even if environmental groups oppose it.) But the perfection of our current environmental and energy legal regime is not one of them. Even if your sole goal were to reduce the carbon emissions produced by the American energy system — even if you set aside the problems with cost, conventional pollution, or monopoly control — the current system sucks.
Advanced nuclear will take a decade or more to hit commercial scale. Meanwhile, the hyperscalers need power now. Enter the uprate.
When America’s tech titans started plowing money into nuclear technology to power data centers in 2024, companies such as Google and Amazon opted to invest first in next-generation reactor startups. But electricity demand is soaring today, and those projects are still years away — at least — from generating power at reasonable commercial rates.
So the industry is hedging by betting on existing nuclear plants to pump out more electricity in the near term. Uprates — renovations that allow nuclear operators to produce more power from existing reactors — are all the rage this year.
In February, the Department of Energy issued its largest-ever loan to Southern Company to fund up to 6 gigawatts of uprates across the utility’s nuclear fleet. Last week, Amazon signed a deal with Constellation Energy, the nation’s largest operator of nuclear reactors, to uprate the Calvert Cliffs plant in Maryland to generate another 190 megawatts on top of its current 1.8-gigawatt output. Soon after, the Energy Department offered nuclear operator Vistra a $4 billion loan to uprate plants in Ohio and Pennsylvania.
Then on Tuesday, Google inked its own deal with Constellation aimed at wringing out 890 megawatts of new power from 11 reactors across PJM Interconnection, the nation’s second-biggest and arguably most overworked grid system.
“Everyone loves nuclear, but it takes a really long time to build,” Raiford Smith, Google’s head of power and energy for the cloud, told me yesterday. “The fastest way to get it is via uprates. It’s real megawatts, but the quicker, shorter-term approach.”
Building new reactors, he said, “is the intermediate term plan, and we see fusion as the longer term bet.” Given that “new data centers are coming on at a gigawatt a clip, that means even with all the uprates, there’s still more to come,” he added.
The investments into existing nuclear stations deliver a win for Constellation, whose chief executive, Joe Dominguez, has been among the more vocal C-suite skeptics of what my colleague Matthew Zeitlin described as utility executives’ “load growth mania” over the past two years. But the deals say as much about the shifting lines in the debate over how to expand the nuclear power fleet in this country — what size reactors are better, how to finance projects — as the disagreement over how much new generation is needed to supply the artificial intelligence boom.
The deal “is a win-win,” Emmet Penney, the director of energy and infrastructure at the think tank Foundation for American Innovation, told me. “Constellation and Google are revealing just how essential our nuclear fleet is to maintaining our energy dominance.”
America’s last attempt at a nuclear buildout ended in a series of financial boondoggles. The problems traced back to numerous factors: Decades without any nuclear construction atrophied the workforce. Electricity market reforms aimed at breaking up monopoly utilities left the industry with few players equipped with large enough balance sheets to take on megaprojects that would take years to build and billions of dollars of upfront capital. Increased competition from cheap natural gas.
The only two new reactors that made it over the finish line, Southern’s pair of Westinghouse AP1000s at the Alvin W. Vogtle Generating Station in eastern Georgia, came in billions of dollars over budget, in part because the developers erred in choosing a Nuclear Regulatory Commission licensing pathway that required long stops and costly delays every time the builders tweaked the design. Since those were the first AP1000s constructed in the U.S., there were plenty of last-minute design kinks to iron out.
In the meantime, the industry rallied behind the idea of small modular reactors. By making individual reactors roughly a third or less powerful than large-scale units such as the AP1000, the thinking went, developers would need to buy more, helping the technology slide down the cost curve through repeated construction and assembly-line manufacturing of components.
While Google and Amazon both backed fourth-generation startups whose designs use coolants other than water, such as liquid sodium or helium gas, the only such reactor operating in the world is in China, and America’s track record of running similar plants is poor. As such, government-owned utilities such as Canada’s Ontario Power Generation and America’s Tennessee Valley Authority have thrown their weight behind third-generation SMRs that essentially just shrink down existing water-cooled technology. The first of GE Vernova Hitachi Nuclear Energy’s BWRX-300s, a 300-megawatt design based on the boiling water reactors that make up about a third of the U.S. fleet, is now underway at OPG’s Darlington plant. In the U.S., meanwhile, the NRC just issued a construction license for the TVA’s first BRWX-300.
But the completion of the second AP1000 at Plant Vogtle demonstrated an uncomfortable reality proposed by researchers at the Massachusetts Institute of Technology: That the next, cheapest reactor to build in the U.S. would be another of Westinghouse’s flagship design. Vogtle Unit 4 came online in 2024 roughly 30% cheaper and faster than its slightly older twin, Vogtle Unit 3.
If that reduction seemed to justify the approach SMR companies were pursuing, a report by an economist and former antinuclear researcher raises new questions. The study by Charles Komanoff, which I covered here last month, suggests that the number of reactors required to achieve major cost reduction through “economies of duplication” pales in comparison to the price drop achieved through “economies of scale.” In other words, the nuclear industry’s time-tested approach to making reactors more economical — making them bigger — is still the best bet.
The Trump administration certainly agrees. The Energy Department laid plans for at least 10 new AP1000s last year, and put up another nearly $20 billion loan package for utilities that form joint ventures with Westinghouse to build one of the 1,100-megawatt reactors. South Korea is currently working out the fine print on a deal to help finance and build as many as six AP1000s and two APR1400s, the Korean rival to the Westinghouse reactor.
Whether any American utilities step up to help build any of those AP1000s remains an open question.
“There’s no way any utilities could consider building a large AP1000 because doing so could bankrupt the whole operation, and they don’t have enough confidence,” Chris Gadomski, the lead nuclear analyst at the consultancy BloombergNEF, told me.
The workforce that constructed the two AP1000s at Vogtle, he said, are now out building data centers. Unlike the Chinese, whose state-owned nuclear companies reverse engineered the AP1000 and made it relatively cheap to build by constructing as many as half a dozen at a time at one location, “we don’t have the wherewithal or sites in this country to build six reactors at once,” Gadomski said. “You’re lucky to build two at one site in this country.”
So fusion and next-generation fission remain years away. Current-generation SMRs come with big questions. And the leading large-scale design, the AP1000, is proving a hard sell to utilities. That leaves two options: Restarting decommissioned plants and uprating current reactors. The Energy Department has pumped billions in loans into projects to restart at least three permanently closed reactors: Holtec’s Palisades plant in Michigan, NextEra’s Duane Arnold facility in Iowa, and Constellation’s Crane Clean Energy Center, née Three Mile Island, in Pennsylvania. The consensus among industry experts is that those are the only three that remain intact enough to start back up; every other shuttered plant is at too advanced a stage of demolition.
That leaves uprates.
There are limits to how much power can be drawn from existing plants, said Jeff Jenkins, the founder and managing partner of Bernhard Capital Partners, an investment firm whose portfolio includes Allied Power, a contractor that has worked with Constellation on past uprates. “There’s still a few gigawatts out there,” he said. “And a gigawatt is a lot.”
But ultimately, the U.S. nuclear buildout needs options.
“It’s very much a hedge,” Gadomski said. “They’re spreading their bets. That’s a strength of Google’s strategy. They’re willing to place bets on advanced reactors, fusion, and still try to double down on the capacity of existing plants.”
On methane rules, British wind, and the Israeli electricity market
Current conditions: Singapore’s air is the worst in the world as wildfire smoke from Indonesia chokes the city state and neighboring Malaysia • Following a summer-like heat wave, temperatures in the American West are set to drop by as much as 50 degrees Fahrenheit as a cold snap moves in • In the Gulf of Mexico, Tropical Storm Isaias officially strengthened into the first Atlantic hurricane of the season this morning.
With its offshore oil fields booming in Guyana and its opportunities opening in Venezuela, Exxon Mobil is eyeing the next location for the Americas’ oil and gas: Trinidad and Tobago. In an interview with the Financial Times this week, the company’s exploration chief said the island nation’s existing oil and gas industry could expand to tap the same basin east of Venezuela that has transformed Guyana from one of the hemisphere’s poorest nations to one of its richest in terms of per capita gross domestic product. “A lot of people ask, ‘well, where’s the next Guyana?’” John Ardill, Exxon Mobil’s vice-president and head of global exploration, told the newspaper. “In Trinidad, we moved in as a play extension to Guyana.” The agreement between Exxon Mobil and the Trinidadian government took “about half as long as it usually takes on a good day,” delivering a pact in “record time.”
America’s oil majors are also looking outside the hemisphere. As you may recall from August, I told you that Exxon Mobil was also considering a big investment in Africa, with Mozambique drawing particular attention. Brazil’s state-owned Petrobras, meanwhile, is expanding its own grasp on the Americas’ oil boom. On Wednesday, Upstream reported, the company bid $590 million for control of an ultra-deepwater concession.
The European Union is pausing implementation of its new rules requiring oil and gas exporters to more scrupulously track data on methane emissions. The U.S., on the other hand, is planning a straight-up rollback. At an oil industry conference in Santa Fe on Wednesday, Environmental Protection Agency Administrator Lee Zeldin teased out plans to gut core parts of the methane regulations finalized in 2024. “This proposal takes on many of the problems American producers and operators have raised with us,” Zeldin said, according to Argus Media. “That includes the burden on marginal wells and oil and gas operators in general, the super emitter program, associated gas and control device requirements.”
Record wind power generation may have slashed how much natural gas Britain needed to burn last month for electricity, but it “wasn’t enough to shield the country from surging prices triggered by the war in Iran,” Bloomberg reported. Wind turbines pumped out 6.6 terawatt-hours of electricity in September, a record for the month and 4% more than a year earlier. As a result, gas-fired generation plunged to its lowest level on record for that month. But day-ahead power rates still doubled from a year earlier.
The world’s capacity of floating offshore wind, the subset of the sector that could vastly expand the areas of shoreline dotted with turbines, has reached 382 megawatts, a 38% surge over the past 12 months, according to a Renewables Now writeup of the latest report from the trade group RenewableUK. Meanwhile, Poland has now constructed all 76 of the standard turbines built into the seabed of the Baltic Sea for its first offshore wind farm. One-third of the turbines are now generating power, according to offshoreWIND.biz.

South Korea plans to speed up its shift away from fossil fuels with a new goal of 100 gigawatts of low-carbon energy additions by 2030 and roughly $747 billion in government-led investment over the next decade. The plan, part of the Korean Green Transformation program, “seeks to make Korea one of the world’s top three green manufacturing powers by developing industries such as hydrogen-reduction steelmaking, next-generation solar cells, and all-solid-state batteries,” according to The Korea Times, an English-language daily. New nuclear reactors are also part of the strategy.
The move comes as Seoul advances construction of as many as eight nuclear reactors in the U.S., including six of America’s Westinghouse AP1000 and two of its own APR1400s, as I told you last week.
The utility megamerger of the century so far is “not in the best interest of Virginians.” That’s the judgment the state’s lieutenant governor, Ghazala Hasmi, rendered this week following a five-city public listening tour. The statement came ahead of the State Corporation Commission’s first local hearing on the deal, and marks what Utility Dive called “the most formal expression of opposition from Virginia’s executive branch so far.” Governor Abigail Spanberger, a fellow Democrat, has not yet taken a definitive position on the merger.
But the deal follows some clear market logic. Among the benefits: It would create, as my colleague Matthew Zeitlin wrote in May, “a storage juggernaut.”

Israel’s booming tech sector and soaring stock market are just two ways its economy has dramatically changed from the socialism that defined the early decades after the country’s founding in 1948. Now that shift also includes the electricity market. Since market reforms allowed private actors into the grid at the start of last year, more than 2 million citizens, representing more than 500,244 private and business customers, have switched from the Israel Electric Corporation to private providers, according to The Jerusalem Post. Ratepayers buying electricity from private suppliers enjoy discounted rates ranging from 7% to 20%, “thanks to the lower generation costs in the private market.” Another 23,286 households and businesses submitted requests to switch suppliers just last month. OPC Energy, an independent power provider based in Tel Aviv, raised $200 million in bond issuances in August.
