America’s energy regulators are hashing it out in the comments.

As decades of administrative law were being rendered irrelevant last week by a landmark Supreme Court decision denying regulators deference in their interpretations of ambiguous legal statues, one such regulator, Mark Christie, already had some ideas about what do with this new development.
Christie, the Federal Energy Regulatory Commission’s sole Republican member, had taken issue with FERC Order No. 1920, which was unveiled in May and established a new set of rules requiring transmission planners to be more proactive in assessing their future needs and how to pay for them. The order was decided in a 2-1 vote along partisan lines and was largely hailed by environmental and climate groups, who saw it as a way to encourage building out the transmission necessary to bring more wind and solar onto the grid.
To some conservatives, however, the order would remove states from their rightful role in the transmission planning process and stick ratepayers with the cost of infrastructure they never asked for. The rule is already being challenged by state utility commissions, Republican state attorneys general, and the country’s largest regional transmission organization in a FERC process known as request for rehearing. Lawsuits will almost certainly follow.
Those lawsuits will play out on the new terrain laid out by Loper Bright Enterprises v. Raimondo, the Supreme Court decision rendered last week, which overturned a decades-old legal principle known as Chevron deference. Named for the 1984 case Chevron v. Natural Resources Defense Council, which established the notion that courts should defer to agencies’ interpretation of ambiguous statutory language to justify their rulemaking activity, Chevron deference formed the legal foundation for much of the U.S. regulatory apparatus.
In Christie’s lengthy and impassioned dissent to the order, however, he signaled that he thought that foundation might be crumbling.
“The final rule does not deserve a shred of deference under Chevron,” Christie wrote. Unlike past transmission planning rules that had survived legal challenge, this new order was “pretextual” and “heavy handed.” An earlier transmission case case that reached the Washington, D.C. Court of Appeals in 2014, South Carolina Public Service Authority v. FERC, upholding FERC’s ability to mandate transmission planning was, Christie wrote, decided in favor of FERC because it “upheld precisely because it was only mandating processes, not outcomes,” whereas the new rule “nakedly intends to produce very specific outcomes.” Christie was basically painting a red flag on the order for the bull of the judicial process to run through.
Once Chevron deference was no longer in force, Christie issued an update to that dissent, writing in a statement on Friday that the “most important legal lifeline that Order No. 1920 needed was pulled away today, and the final rule’s chances of surviving court challenges just shrank to slim to none.” He referred to outstanding petitions for rehearing the order as “devastating takedowns.” Without Chevron to lean on, he prognosticated, “the Commission can wait for a court to strike down” 1920, or it can answer “those many petitions asking for rehearing or amendments with a new opportunity for amendments.”
In other words, the order should not have had Chevron’s protection, but now that it doesn’t, it’s toast.
On Monday, the Commission’s Democratic Chairman Willie Phillips released a statement (because there was nothing else going on in the legal world that day) arguing that the Commission’s ability to regulate both planning and the distribution of costs “has long been recognized by bipartisan majorities of the Commission and U.S. Court of Appeals for the District of Columbia Circuit,” adding that “nothing in the Supreme Court’s Loper Bright decision overturning the Chevron doctrine calls that conclusion into question.”
He also gave a preview of how the Commission will likely defend the rule in federal court. Order No. 1920 “fits easily within the South Carolina precedent,” he wrote. “It does not promote particular public policies, does not dictate specific outcomes, does not include any selection mandate whatsoever, and employs only the lightest touch possible on cost allocation by simply restating the well-established cost causation principle.”
In conclusion, according to Phillips, Christie’s statement “does not provide a logical or reasonable basis for calling into question whether we have that authority in the first place.”
“It’s not every day that two FERC commissioners just decide to release their thoughts on the latest Supreme Court case,” Ari Peskoe, the director of the Electricity Law Initiative at Harvard Law School, told me.
FERC’s likely argument rests on two legal pillars. The first is that FERC gets its authority from the Federal Power Act, which calls for utility rates to be “just and reasonable” and not “unduly discriminatory or preferential.” FERC has argued that this gives it power over practices that directly affect rates, including transmission planning, which the D.C. Circuit affirmed in South Carolina.
In a separate 2016 case, the Supreme Court ruled that FERC could make rules on practices that directly affect wholesale electricity rates but not retail sales. This case did not depend on Chevron, with Justice Elena Kagan writing in her opinion that the justices “think FERC’s authority clear.” The combined D.C. and Supreme Court precedent, Peskoe said, adds up to FERC having “authority when something directly affects rates."
But in this new legal environment, these precedents may not be enough for a fresh case against FERC's transmission planning authority.
“What does happen now? Who knows,” University of Richmond law professor Joel Eisen told me. “What you would expect now is for litigants to say that any major FERC order, including this one, is inconsistent with the statutory authority that the agency has. They would cite Loper Bright to say that the court has to make an independent judgment that FERC has interpreted law to grant authority to do sweeping change to transmission planning, and that is simply no longer the case,” Eisen said.
Much of FERC’s more than 1,300-page order is devoted to detailed analysis of the electricity market as it stands now and how it will evolve over time, justifying the new transmission planning rules. It’s this record, Eisen said, that might let the order survive in a post-Chevron world, even when FERC asserting that the Federal Power Act gives it the right to set rules may be insufficient on its own.
“That may not have been done as an explicit nod to whether a court might uphold it under Chevron going forward. “It seems to me at least that in this new landscape, what will matter is the robustness of the agency grounded in its expertise,” Eisen told me. “The voluminous record supporting 1920 may be persuasive to a federal court.”
But, as Eisen and Peskoe both warned, which federal court may be as important — if not more so — than any argument FERC makes.
Will FERC's arguments about the nature of the electricity market and precedents relating to interpretation of the Federal Power Act fly in, say, a Texas federal court in the Fifth Circuit, where state utility commissions or Republican attorneys general may file suit? District and appeals court judges in the Fifth Circuit have shown great eagerness to throw out Biden-era rules, with a federal judge in Louisiana only this week blocking the Biden administration’s pause on approving new natural gas export terminals.
“If it goes to the Fifth Circuit,” Peskoe said, “that will be bad news.”

Flames have erupted in the “Blue Zone” at the United Nations Climate Conference in Brazil.
A literal fire has erupted in the middle of the United Nations conference devoted to stopping the planet from burning.
The timing couldn’t be worse. Today is the second to last day of the annual climate meeting known as COP30, taking place on the edge of the Amazon rainforest in Belém, Brazil. Delegates are in the midst of heated negotiations over a final decision text on the points of agreement this session.
A number of big questions remain up in the air, including how countries will address the fact that their national plans to cut emissions will fail to keep warming “well under 2 degrees Celsius,” the target they supported in the 2015 Paris Agreement. They are striving to reach agreement on a list of “indicators,” or metrics by which to measure progress on adaptation. Brazil has led a push for the conference to mandate the creation of a global roadmap off of fossil fuels. Some 80 countries support the idea, but it’s still highly uncertain whether or how it will make its way into the final text.
Just after 2:00 p.m. Belém time, 12 p.m. Eastern, I was in the middle of arranging an interview with a source at the conference when I got the following message:
“We've been evacuated due to a fire- not exactly sure how the day is going to continue.”
The fire is in the conference’s “Blue Zone,” an area restricted to delegates, world leaders, accredited media, and officially designated “observers” of the negotiations. This is where all of the official negotiations, side events, and meetings take place, as opposed to the “Green Zone,” which is open to the public, and houses pavilions and events for non-governmental organizations, business groups, and civil society groups.
It is not yet clear what the cause of the fire was or how it will affect the home sprint of the conference.
Outside of the venue, a light rain was falling.

The Trump administration on Wednesday proposed significant new limits on federal protection under the Endangered Species Act. A series of four tweaked rules would reset how the bedrock environmental law to prevent animal and plant extinctions could be used to block oil drilling, logging, and mining in habitats for endangered wildlife, The New York Times reported. Among the most contentious is a proposal to allow the government to consider economic factors before determining whether to list a species as endangered. Another change would raise the bar for enacting protections based on predicted future threats such as climate change. “This administration is restoring the Endangered Species Act to its original intent, protecting species through clear, consistent and lawful standards that also respect the livelihoods of Americans who depend on our land and resources,” Secretary of the Interior Doug Burgum said in a statement.
In Congress, meanwhile, bipartisan reforms to make federal permitting easier are advancing. Representative Scott Peters, the Democrat in charge of the permitting negotiations, called the SPEED Act introduced by Representative Bruce Westerman, the Republican chairman of the Natural Resources Committee, a “huge step forward,” according to a post on X from Politico reporter Josh Siegel. But Peters hinted that getting the legislation to the finish line would require the executive branch to provide “permit certainty,” a thinly-veiled reference to Democrats’ demand that the Trump administration ease off its so-called “total war on wind” turbines.
In World Cup soccer, Turkey hasn’t faced Australia in more than a decade. But the two countries went head to head in the competition to host next year’s United Nations climate summit, COP31. Turkey won, Bloomberg reported last night. Australia’s defeat is a blow not just to Canberra but to those who had hoped a summit Down Under would set the stage for an “island COP.” The pre-conference leaders’ gathering is set to take place on an as-yet-unnamed Pacific island, which had raised hopes that the next confab could put fresh emphasis on the concerns of low-lying nations facing sea-level rise.
More than a dozen states where data centers are popping up could face electric power emergencies under extreme conditions this winter, a grid security watchdog warned this week, E&E News reported. The North American Electric Reliability Corporation listed New England, the Carolinas, most of Texas, and the Pacific Northwest among the most threatened regions. If those emergencies take place, the grid operators would need to import more electricity from other regions and seek voluntary power cutbacks from customers before resorting to rotating blackouts.

The United States is on the cusp of restarting a permanently shuttered atomic power plant for the first time. But anti-nuclear groups are making a last-ditch effort to block the revival. In a complaint filed Monday in the U.S. District court for the Western District of Michigan, a trio of activist organizations — Beyond Nuclear, Don’t Waste Michigan, and Michigan Safe Energy Future — argued that the plant should never have received regulatory approval for a restart. As I wrote in this newsletter at the time, the Nuclear Regulatory Commission granted plant owner Holtec International permission to go ahead with the restoration in July. Last month, the company — best known for manufacturing waste storage vessels and decommissioning defunct plants — received a shipment of fuel for the single-reactor station, as I reported here. While the opponents are asking the federal judge to intervene, state lawmakers in Michigan are considering new subsidies for nuclear power, Bridge Michigan reported.
Further north along Michigan’s western coastline, a coal-fired power plant set to close down in May got another extension from the Trump administration. In an order signed Tuesday, Secretary of Energy Chris Wright renewed his direction to utility Consumers Energy to hold off on shutting down the facility, which the administration deemed necessary to stave off blackouts. The latest order, Michigan Advance noted, extends until February 17, 2026. President Donald Trump’s efforts to prop up the coal industry haven’t gone so well elsewhere. As Heatmap’s Matthew Zeitlin reported last week, coal-fired stations keep breaking down, with equipment breaking at more than twice the rate of wind turbines.
Matthew had another timely story out yesterday: Members of the PJM Interconnection’s voting base of advisers met Wednesday to consider a dozen different proposals for how to bring more data centers online put forward by data center companies, transmission developers, utilities, state lawmakers, advocates, PJM’s market monitor, and PJM itself. None passed. “There was no winner here,” PJM chief executive Manu Asthana told the meeting following the announcement of the vote tallies. There was, however, “a lot of information in these votes,” he added. “We’re going to study them closely.” The grid operator still aims to get something to federal regulators by the end of the year.
Here’s a gruesome protocol that apparently exists when a toothed whale washes up. Federal officials arrived on Nantucket on Wednesday afternoon to remove a beached sperm whale’s jaw. Per the Nantucket Current: “This is being done to prevent any theft of its teeth, which are illegal to take and possess. The Environmental Police will take the jaw off-island.”
Members of the nation’s largest grid couldn’t agree on a recommendation for how to deal with the surge of incoming demand.
The members of PJM Interconnection, the country’s largest electricity market, held an advisory vote Wednesday to help decide how the grid operator should handle the tidal wave of incoming demand from data centers. Twelve proposals were put forward by data center companies, transmission companies, power companies, utilities, state legislators, advocates, PJM’s market monitor, and PJM itself.
None of them passed.
“There was no winner here,” PJM chief executive Manu Asthana told the meeting following the announcement of the vote tallies. There was, however, “a lot of information in these votes,” he added. “We’re going to study them closely.”
The PJM board was always going to make the final decision on what it would submit to federal regulators, and will try to get something to the Federal Energy Regulatory Commission by the end of the year, Asthana said — just before he plans to step down as CEO.
“PJM opened this conversation about the integration of large loads and greatly appreciates our stakeholders for their contributions to this effort. The stakeholder process produced many thoughtful proposals, some of which were introduced late in the process and require additional development,” a PJM spokesperson said in a statement. “This vote is advisory to PJM’s independent Board. The Board can and does expect to act on large load additions to the system and will make its decision known in the next few weeks.”
The surge in data center development — actual and planned — has thrown the 13-state PJM Interconnection into a crisis, with utility bills rising across the network due to the billions of dollars in payments required to cover the additional costs.
Those rising bills have led to cries of frustration from across the PJM member states — and from inside the house.
“The current supply of capacity in PJM is not adequate to meet the demand from large data center loads and will not be adequate in the foreseeable future,” PJM’s independent market monitor wrote in a memo earlier this month. “Customers are already bearing billions of dollars in higher costs as a direct result of existing and forecast data center load,” it said in a quarterly report released just a few days letter, pegging the added charges to ensure that generators will be available in times of grid stress due to data center development at over $16 billion.
PJM’s initial proposal to deal with the data center swell would have created a category for new large sources of demand on the system to interconnect without the backing of capacity; in return, they’d agree to have their power supply curtailed when demand got too high. The proposal provoked outrage from just about everyone involved in PJM, including data center developers and analysts who were open to flexibility in general, who said that the grid operator was overstepping its responsibilities.
PJM’s subsequent proposal would allow for voluntary participation in a curtailment program, but was lambasted by environmental groups like Evergreen Collaborative for not having “any semblance of ambition.” PJM’s own market monitor said that voluntary schemes to curtail power “are not equivalent to new generation,” and that instead data centers should “be required to bring their own new generation” — essentially to match their own demand with new supply.
A coalition of environmental groups, including the Natural Resources Defence Council and state legislators in PJM, said in their proposal that data centers should be required to bring their own capacity — crucially counting demand response (being paid to curtail power) as a source of capacity.
“The growth of data centers is colliding with the reality of the power grid,” Tom Rutigliano, who works on grid issues for the Natural Resources Defense Council, said in a statement. “PJM members weren’t able to see past their commercial interests and solve a critical reliability threat. Now the board will need to stand up and make some hard decisions.”
Those decisions will come without any consensus from members about what to do next.
“Just because none of these passed doesn’t mean that the board will not act,” David Mills, the chairman of PJM’s board of managers, said at the conclusion of the meeting. “We will make our best efforts to put something together that will address the issues.”
