It’s puzzling, then, that the Trump administration is pouring vast government resources into saving aging coal plants and expediting advanced nuclear projects — two sources of energy that are famously financial black holes.
The Energy Department announced it would invest $625 million to “reinvigorate and expand America’s coal industry” in late September. Earlier this year, the agency also made $900 million available to “unlock commercial deployment of American-made small modular reactors.”
It’s hard to imagine what economic yardsticks would warrant funding to keep coal plants open. The cost of operating a coal plant in the U.S. has increased by nearly 30% since 2021 — faster than inflation — according to research by Energy Innovation. Driving that increase is the cost of coal itself, as well as the fact that the nation’s coal plants are simply getting very old and more expensive to maintain. “You can put all the money you want into a clunker, but at the end of the day, it’s really old, and it’s just going to keep getting more expensive over time, even if you have a short term fix,” Michelle Solomon, a program manager at Energy Innovation who authored the research, told me.
Keeping these plants online — even if they only operate some of the time— inevitably raises electricity bills. That’s because in many of the country’s electricity markets, the cost of power on any given day is determined by the most expensive plant running. On a hot summer day when everyone’s air conditioners are working hard and the grid operator has to tell a coal plant to switch on to meet demand, every electron delivered in the region will suddenly cost the same as coal, even if it was generated essentially for free by the sun or wind.
The Trump administration has also based its support for coal plants on the idea that they are needed for reliability. In theory, coal generation should be available around the clock. But in reality, the plants aren’t necessarily up to the task — and not just because they’re old. Sandy Creek in Texas, which began operating in 2013 and is the newest coal plant in the country, experienced a major failure this past April and is now expected to stay offline until 2027, according to the region’s grid operator. In a report last year, the North American Electric Reliability Corporation warned that outage rates for coal plants are increasing. This is in part due to wear and tear from the way these plants cycle on and off to accommodate renewable energy sources, the report said, but it’s also due to reduced maintenance as plant operators plan to retire the facilities.
“You can do the deferred maintenance. It might keep the plant operating for a bit longer, but at the end of the day, it’s still not going to be the most efficient source of energy, or the cheapest source of energy,” Solomon said.
The contradictions snowball from there. On September 30, the DOE opened a $525 million funding opportunity for coal plants titled “Restoring Reliability: Coal Recommissioning and Modernization,” inviting coal-fired power plants that are scheduled for retirement before 2032 or in rural areas to apply for grants that will help keep them open. The grant paperwork states that grid capacity challenges “are especially acute in regions with constrained transmission and sustained load growth.” Two days later, however, as part of the agency’s mass termination of grants, it canceled more than $1.3 billion in awards from the Grid Deployment Office to upgrade and install new transmission lines to ease those constraints.
The new funding opportunity may ultimately just shuffle awards around from one coal plant to another, or put previously-awarded projects through the time-and-money-intensive process of reapplying for the same funding under a new name. Up to $350 million of the total will go to as many as five coal plants, with initial funding to restart closed plants or to modernize old ones, and later phases designated for carbon capture, utilization, and storage retrofits. The agency said it will use “unobligated” money from three programs that were part of the 2021 Infrastructure Investment and Jobs Act: the Carbon Capture Demonstration Projects Program, the Carbon Capture Large-Scale Pilot Projects, and the Energy Improvements in Rural or Remote Areas Program.
In a seeming act of cognitive dissonance, however, the agency has canceled awards for two coal-fired power plants that the Biden administration made under those same programs. One, a $6.5 million grant to Navajo Transitional Energy Company, a tribal-owned entity that owns a stake in New Mexico’s Four Corners Generating Station, would have funded a study to determine whether adding carbon capture and storage to the plant was economically viable. The other, a $50 million grant to TDA Research that would have helped the company validate its CCS technology at Dry Fork Station, a coal plant in Wyoming, was terminated in May.
Two more may be out the window. A new internal agency list of grants labeled “terminate” that circulated this week included an $8 million grant for the utility Duke Energy to evaluate the feasibility of capturing carbon from its Edwardsport plant in Indiana, and $350 million for Project Tundra, a carbon capture demonstration project at the Milton R. Young Station in North Dakota.
“It’s not internally consistent,” Jack Andreason Cavanaugh, a global fellow at the Columbia University’s Carbon Management Research Initiative, told me. “You’re canceling coal grants, but then you’re giving $630 million to keep them open. You’re also investing a ton of time and money into nuclear — which is great, to be clear — but these small modular reactors haven’t been deployed in the United States, and part of the reason is that they’re currently not economically viable.”
The closest any company has come thus far to deploying a small modular reactor in the U.S. is NuScale, a company that planned to build its first-of-a-kind reactors in Idaho and had secured agreements to sell the power to a group of public utilities in Utah. But between 2015, when it was first proposed, and late 2023, when it died, the project’s budget tripled from $3 billion to more than $9 billion, while its scale was reduced from 600 megawatts to 462 megawatts. Not all of that was inevitable — costs rose dramatically in the final few years due to inflation. The reason NuScale ultimately pulled out of the project is that the cost of electricity it generated was going to be too high for the market to bear.
It’s unclear how heavily the DOE will weigh project financials in the application process for the $900 million for nuclear reactors. In its funding announcement, it specified that the awards would be made “solely based on technical merit.” The agency’s official solicitation paperwork, however, names “financial viability” as one of the key review criteria. Regardless, the Trump administration appears to recognize the value in funding first-of-a-kind, risky technologies when it comes to nuclear, but is not applying the same standards to direct air capture or hydrogen plants.
I asked the Department of Energy to share the criteria it used in the project review process to determine economic viability. In response, spokesperson Ben Dietderich encouraged me to read Wright’s memorandum describing the review process from May. The memo outlines what types of documentation the agency will evaluate to reach a decision, but not the criteria for making that decision.
Solomon agreed that advanced nuclear might one day meet the grid’s growing power needs, but not anytime soon. “Hopefully in the long term, this technology does become a part of our electricity system. But certainly relying on it in the short term has real risks to electricity costs,” she said. “And also reliability, in the sense that the projects might not materialize.”
