Fossil fuel plant retirements are slowing down, and projected load growth is to blame.
To fully decarbonize the electricity system will require more than just the rapid deployment of non-carbon-emitting generation capacity, plus the transmission necessary to get that electricity to where it needs to go. It will also require that our existing stock of electricity generation — which is largely natural gas- and coal-powered — get mostly mothballed. So far, this process has been proceeding briskly. Renewable deployment is on the way up and is projected to accelerate, and older electricity generation was sliding quickly but gracefully into retirement — until recently.
Retirements of existing generation have slowed down dramatically in the first half of this year, which is on pace to be the slowest for existing generation retirements since 2011, according to new data from the Energy Information Administration.
In the first half of the year, some 5.1 gigawatts of generating capacity have been retired, and another 2.4 gigawatts are scheduled to be retired by year’s end, for a projected total of 7.5 retired gigawatts. From 2004 to 2023, by contrast, just over 12 gigawatts of capacity were retired each year on average, with almost 15 gigawatts retired per year this decade. Since 2022, according to EIA data, over 90% of retired capacity has been coal or natural gas.
What’s behind the slowdown? “Reliability is threatened because the grid conditions are tightening,” Douglas Giuffre, executive director of gas, power and renewables analysis at S&P Global Commodity Insights, explained in an email. “This is partly due to the recent pace of coal and natural gas retirements in the U.S., which worked off some of the excess capacity in power markets. Now we are seeing tighter reserve margins, and a relatively thin pipeline of new gas-fired projects that can come online quickly.” That’s especially concerning for utilities at a time when projected electricity demand is way, way up.
The wave of retirements was a national phenomenon, often having nothing to do with state-level plans to decarbonize. Coal and gas were being retired so steadily over the past 20 years not just because plants were aging, but also because power use was essentially flat from the early 2000s through, essentially, yesterday. This meant that older plants — especially dirty coal plants — became uneconomic to run, especially as natural gas prices began to fall.
Now, we are in a completely different world. Electricity use is forecast to start growing again, thanks to a buildout of new data centers and manufacturing, plus the ongoing electrification of automobiles and home heating and cooling.
The Southeast offers an example of how these trends have played out on the ground. In December 2020, the Mississippi Public Service Commission determined that the state had “excess reserves … largely due to decreases in projected load” and ordered a 950 megawatt reduction in generating capacity by Mississippi Power by 2027. A consulting firm hired by the commission determined that Plant Daniel, a coal plant, was “relatively inefficient compared to other available resources;” a few months later, the utility said it would decommission Plant Daniel by 2027.
Then Georgia Power, the utility that covers most of the state (and, like Mississippi Power, a subsidiary of Southern Company), rushed out a new three-year plan for its future power usage less than a year after finalizing its old one. Its demand forecast through the end of the decade had jumped from 400 megawatts to 6,600 megawatts, the result of a projected boom in data center construction.
“They came in with a preselected list of ways it wanted to meet that power need,” including buying power from Plant Daniel and new gas, Bob Sherrier, a staff attorney at the Southern Environmental Law Center, told me. Georgia Power told the state’s utility commission that to respond to growing demand it would need to extend contracts with its sister utility in Mississippi — which meant not only that Daniel would remain open for at least another year — and build new new plants that could run on gas or diesel, plans for which regulators approved on Tuesday. The utility also hinted that its existing plans to euthanize, for the most part, its coal-fired generation fleet by the end of 2028 were likely to be revised.
“To meet that projected need, the utilities are reverting to what they know, which is fossil fuels,” Sherrier said.
In vertically integrated markets, where utilities own generating assets and sell power to customers, environmentalists have seen delayed retirements and the building of new fossil plants as examples of utilities slipping into their comfort zone, building and operating expensive projects instead of developing or procuring renewables to handle rising demand.
But it's not just in vertically integrated markets where fossil retirements are being delayed. In Maryland, for instance, Brandon Shores, a coal-fired power plant that was scheduled to close in 2025, is staying open because PJM Interconnection, the regional electricity market, determined that a plan to replace it with battery storage was not a “realistic option at present” nor “technically viable to resolve the reliability violations or avoid the need for an RMR agreement at this time,” PJM president Manu Asthana said in a letter to Paul Pinsky, the director of the Maryland Energy Administration. The transmission investments required to make up the difference, meanwhile, would take several years.
Along with the neighboring Wagner plant, which burns a mix of coal, oil, and natural gas, Brandon Shores will likely stay open more than three years past its planned retirement date thanks to what’s known as a “reliability must run” contract, which “would put Maryland ratepayers on the hook for over $600 million dollars in out-of-market payments,” according to a letter written by several Maryland congressional representatives to PJM.
Environmental advocates have blamed PJM for not doing enough proactive transmission planning to account for predictable and scheduled plant retirements.
The slowing retirements mean that emissions from the electricity sector, which have been falling since the mid-2000s (with occasional bumps up as the economy has recovered from downturns), are expected to plateau over the next year or so. EIA forecasts show carbon dioxide emissions from electricity as essentially flat from 2023 to 2025, with increased natural gas emissions essentially offsetting falling coal emissions.
There is a bright side to the data, however. So far this year, the U.S. has installed just over 20 gigawatts of new generation, 80% of which has been solar and battery storage, including a 600-plus megawatt projects in Nevada and Texas. If added generation comes on in the second half of this year as planned, the EIA projects we’ll have 15 gigawatts of battery storage by year’s end. Along with the large and growing solar generation in states like California, Nevada, and Texas, the U.S. is getting closer to a grid that can, at least, run without carbon emissions day or night.

A conversation with Mary King, a vice president handling venture strategy at Aligned Capital
Today’s conversation is with Mary King, a vice president handling venture strategy at Aligned Capital, which has invested in developers like Summit Ridge and Brightnight. I reached out to Mary as a part of the broader range of conversations I’ve had with industry professionals since it has become clear Republicans in Congress will be taking a chainsaw to the Inflation Reduction Act. I wanted to ask her about investment philosophies in this trying time and how the landscape for putting capital into renewable energy has shifted. But Mary’s quite open with her view: these technologies aren’t going anywhere.
The following conversation has been lightly edited and abridged for clarity.
How do you approach working in this field given all the macro uncertainties?
It’s a really fair question. One, macro uncertainties aside, when you look at the levelized cost of energy report Lazard releases it is clear that there are forms of clean energy that are by far the cheapest to deploy. There are all kinds of reasons to do decarbonizing projects that aren’t clean energy generation: storage, resiliency, energy efficiency – this is massively cost saving. Like, a lot of the methane industry [exists] because there’s value in not leaking methane. There’s all sorts of stuff you can do that you don’t need policy incentives for.
That said, the policy questions are unavoidable. You can’t really ignore them and I don’t want to say they don’t matter to the industry – they do. It’s just, my belief in this being an investable asset class and incredibly important from a humanity perspective is unwavering. That’s the perspective I’ve been taking. This maybe isn’t going to be the most fun market, investing in decarbonizing things, but the sense of purpose and the belief in the underlying drivers of the industry outweigh that.
With respect to clean energy development, and the investment class working in development, how have things changed since January and the introduction of these bills that would pare back the IRA?
Both investors and companies are worried. There’s a lot more political and policy engagement. We’re seeing a lot of firms and organizations getting involved. I think companies are really trying to find ways to structure around the incentives. Companies and developers, I think everybody is trying to – for lack of a better term – future-proof themselves against the worst eventuality.
One of the things I’ve been personally thinking about is that the way developers generally make money is, you have a financier that’s going to buy a project from them, and the financier is going to have a certain investment rate of return, or IRR. So ITC [investment tax credit] or no ITC, that IRR is going to be the same. And the developer captures the difference.
My guess – and I’m not incredibly confident yet – but I think the industry just focuses on being less ITC dependent. Finding the projects that are juicier regardless of the ITC.
The other thing is that as drafts come out for what we’re expecting to see, it’s gone from bad to terrible to a little bit better. We’ll see what else happens as we see other iterations.
How are you evaluating companies and projects differently today, compared to how you were maybe before it was clear the IRA would be targeted?
Let’s say that we’re looking at a project developer and they have a series of projects. Right now we’re thinking about a few things. First, what assets are these? It’s not all ITC and PTC. A lot of it is other credits. Going through and asking, how at risk are these credits? And then, once we know how at risk those credits are we apply it at a project level.
This also raises a question of whether you’re going to be able to find as many projects. Is there going to be as much demand if you’re not able to get to an IRR? Is the industry going to pay that?
What gives you optimism in this moment?
I’ll just look at the levelized cost of energy and looking at the unsubsidized tables say these are the projects that make sense and will still get built. Utility-scale solar? Really attractive. Some of these next-gen geothermal projects, I think those are going to be cost effective.
The other thing is that the cost of battery storage is just declining so rapidly and it’s continuing to decline. We are as a country expected to compare the current price of these technologies in perpetuity to the current price of oil and gas, which is challenging and where the technologies have not changed materially. So we’re not going to see the cost decline we’re going to see in renewables.
And more news around renewable energy conflicts.
1. Nantucket County, Massachusetts – The SouthCoast offshore wind project will be forced to abandon its existing power purchase agreements with Massachusetts and Rhode Island if the Trump administration’s wind permitting freeze continues, according to court filings submitted last week.
2. Tippacanoe County, Indiana – This county has now passed a full solar moratorium but is looking at grandfathering one large utility-scale project: RWE and Geenex’s Rainbow Trout solar farm.
3. Columbia County, Wisconsin – An Alliant wind farm named after this county is facing its own pushback as the developer begins the state permitting process and is seeking community buy-in through public info hearings.
4. Washington County, Arkansas – It turns out even mere exploration for a wind project out in this stretch of northwest Arkansas can get you in trouble with locals.
5. Wagoner County, Oklahoma – A large NextEra solar project has been blocked by county officials despite support from some Republican politicians in the Sooner state.
6. Skagit County, Washington – If you’re looking for a ray of developer sunshine on a cloudy day, look no further than this Washington State county that’s bucking opposition to a BESS facility.
7. Orange County, California – A progressive Democratic congressman is now opposing a large battery storage project in his district and talking about battery fire risks, the latest sign of a populist revolt in California against BESS facilities.
Permitting delays and missed deadlines are bedeviling solar developers and activist groups alike. What’s going on?
It’s no longer possible to say the Trump administration is moving solar projects along as one of the nation’s largest solar farms is being quietly delayed and even observers fighting the project aren’t sure why.
Months ago, it looked like Trump was going to start greenlighting large-scale solar with an emphasis out West. Agency spokespeople told me Trump’s 60-day pause on permitting solar projects had been lifted and then the Bureau of Land Management formally approved its first utility-scale project under this administration, Leeward Renewable Energy’s Elisabeth solar project in Arizona, and BLM also unveiled other solar projects it “reasonably” expected would be developed in the area surrounding Elisabeth.
But the biggest indicator of Trump’s thinking on solar out west was Esmeralda 7, a compilation of solar project proposals in western Nevada from NextEra, Invenergy, Arevia, ConnectGen, and other developers that would, if constructed, produce at least 6 gigawatts of power. My colleague Matthew Zeitlin was first to report that BLM officials updated the timetable for fully permitting the expansive project to say it would complete its environmental review by late April and be completely finished with the federal bureaucratic process by mid-July. BLM told Matthew that the final environmental impact statement – the official study completing the environmental review – would be published “in the coming days or week or so.”
More than two months later, it’s crickets from BLM on Esmeralda 7. BLM never released the study that its website as of today still says should’ve come out in late April. I asked BLM for comment on this and a spokesperson simply told me the agency “does not have any updates to share on this project at this time.”
This state of quiet stasis is not unique to Esmeralda; for example, Leeward has yet to receive a final environmental impact statement for its 700 mega-watt Copper Rays solar project in Nevada’s Pahrump Valley that BLM records state was to be published in early May. Earlier this month, BLM updated the project timeline for another Nevada solar project – EDF’s Bonanza – to say it would come out imminently, too, but nothing’s been released.
Delays happen in the federal government and timelines aren’t always met. But on its face, it is hard for stakeholders I speak with out in Nevada to take these months-long stutters as simply good faith bureaucratic hold-ups. And it’s even making work fighting solar for activists out in the desert much more confusing.
For Shaaron Netherton, executive director of the conservation group Friends of the Nevada Wilderness, these solar project permitting delays mean an uncertain future. Friends of the Nevada Wilderness is a volunteer group of ecology protection activists that is opposing Esmeralda 7 and filed its first lawsuit against Greenlink West, a transmission project that will connect the massive solar constellation to the energy grid. Netherton told me her group may sue against the approval of Esmeralda 7… but that the next phase of their battle against the project is a hazy unknown.
“It’s just kind of a black hole,” she told me of the Esmeralda 7 permitting process. “We will litigate Esmeralda 7 if we have to, and we were hoping that with this administration there would be a little bit of a pause. There may be. That’s still up in the air.”
I’d like to note that Netherton’s organization has different reasons for opposition than I normally write about in The Fight. Instead of concerns about property values or conspiracies about battery fires, her organization and a multitude of other desert ecosystem advocates are trying to avoid a future where large industries of any type harm or damage one of the nation’s most biodiverse and undeveloped areas.
This concern for nature has historically motivated environmental activism. But it’s also precisely the sort of advocacy that Trump officials have opposed tooth-and-nail, dating back to the president’s previous term, when advocates successfully opposed his rewrite of Endangered Species Act regulations. This reason – a motivation to hippie-punch, so to speak – is a reason why I hardly expect species protection to be enough of a concern to stop solar projects in their tracks under Trump, at least for now. There’s also the whole “energy dominance” thing, though Trump has been wishy-washy on adhering to that goal.
Patrick Donnelly, great basin director at the Center for Biological Diversity, agrees that this is a period of confusion but not necessarily an end to solar permitting on BLM land.
“[Solar] is moving a lot slower than it was six months ago, when it was coming at a breakneck pace,” said Patrick Donnelly of the Center for Biological Diversity. “How much of that is ideological versus 15-20% of the agencies taking early retirement and utter chaos inside the agencies? I’m not sure. But my feeling is it’s less ideological. I really don’t think Trump’s going to just start saying no to these energy projects.”
