A new analysis of federal data shows that U.S. power plants are sitting on a huge stockpile of coal, much of which came from the Powder River Basin. Experts say the surplus could reduce demand.

The stockpiles amount to 138 million tons of coal, with a value of $6.5 billion, according to a new report from the Institute for Energy Economics and Financial Analysis.

Seth Feaster is an institute energy data analyst and one of the authors, and said coal deliveries to power plants have been declining - but added that "doesn't appear to be enough."

"That's going to squeeze coal producers for the next year or more," said Feaster, "because the power companies are going to have to burn down that inventory, and try and reduce what their deliveries are going to be."

Feaster said previous stockpiles have taken up to three years to get through.

This excess can happen when the price of natural gas drops, driving power plants that utilize a mix of fuels to opt for more natural gas.

Feaster said another reason power companies may choose gas over coal is that while coal plants are aging and declining, natural-gas production has become a more reliable and responsive source - which mixes well with increasing renewable energy supplies.

"The ability of gas-fired power to adjust quickly to the ups and downs of solar and wind production," said Feaster, "has made it an integral part of the modern energy mix for power production."

Feaster said renewable energy is appealing to power companies because it's relatively inexpensive to build, and there are no additional fuel costs after it's built.

Although the incoming Trump administration appears to be broadly supportive of fossil fuels, Feaster said gas use will affect coal demand.

"I think it's pretty clear that anything that's going to help gas in the overall energy mix is likely to help gas much more than coal," said Feaster, "because it's going to keep prices on the fuel cheaper."

According to the report, coal deliveries have been decreasing for years. About 30 million tons were delivered per month this year, compared with 80 million tons per month in 2008.

Thousands of Kentucky families face utility disconnections this summer, and the latest budget reconciliation bill would eliminate the Low-Income Home Energy Assistance Program, which helps millions of Americans afford their heating and cooling expenses.

The move would significantly impact Eastern Kentucky counties, where many households spend more than a third of their income on energy bills, said Chris Woolery, energy projects coordinator for the Mountain Association. He added that many households are stressed over both paying their energy bills and providing for their families' other needs.

"We're talking hundreds of thousands of households across Kentucky," he said, "and some of them face disconnections."

In 2024 alone, the program was utilized more than 219,000 times by households across the state, who received up to $250 per season. Supporters of defunding the program have argued that lower energy prices are on the horizon.

Earlier this year, lawmakers introduced legislation aimed at preventing disconnections during extreme weather events.

Woolery said eastern Kentucky is one of the most energy-burdened regions in the country. Without the energy assistance program as a safety net for working families, elderly residents and people with disabilities, he said, state-level protections are critical.

"We're trying to get more Kentuckians involved in the conversation," he said, "and that's why we're pushing for disconnection protections at the legislative level."

According to state data, Kentucky's average energy burden is 3%, but for low-income and disadvantaged communities, energy costs can be as high as 18%. The federal government allocated approximately $54 million in safety-net funds to Kentucky in fiscal year 2025.

Michigan taxpayers may end up footing the bill to keep an aging coal plant open.

The J.H. Campbell plant was scheduled to close on May 31, but a last-minute order from the Department of Energy is forcing it to stay open.

The owner of the plant, Consumers Energy, says it wants the facility shuttered, but its hands are tied.

Dennis Wamsted, energy analyst with the Institute for Energy Economics and Financial Analysis, said the Trump administration can use the Federal Power Act to force aging coal plants to stay open under emergency conditions.

"A really severe winter storm requires plants to continue to operate above what might be their normal generation levels," said Wamsted. "So there are provisions to operate plants or order them to remain online if there's a real emergency. This was not a real emergency."

Since 2021, Consumers Energy has built new solar and wind generation resources and purchased a natural gas-fired power plant.

These moves were made to replace energy produced by the J.H. Campbell plant and for a complete transition from coal production by the end of 2025.

President Donald Trump issued an executive order in April authorizing the Department of Energy to keep plants open using the Federal Power Act.

Trump said he wants to meet a rise in electricity demand due to an anticipated surge in domestic manufacturing and the construction of artificial intelligence data processing centers.

Wamsted said he believes the taxpayer burden to support J.H. Campbell is unfair and expensive.

When estimating the plant's operating costs, he cited an example from 2023, when the owners of a West Virginia coal plant were forced to keep a site open.

Monthly operating costs were at $3 million. Wamsted called that a "good figure" for J.H. Campbell's operational costs.

"They have to pay the staff to keep the plant there," said Wamsted. "They have to pay to run the pipes and keep the turbine so it can actually produce electricity. So you end up paying that $3 million or more just to keep the plant able to operate."

Wamsted said he is not aware of any legal action taken to force the plant's closure, move upkeep expenses out of taxpayers' hands, or recover the money at a later date.

He said things could change if there's a filing with the Federal Energy Regulatory Commission, which would allow outside intervenors to force the plant to close or challenge a tariff.

Pennsylvania's U.S. Senators are being asked to do what they can to safeguard federal clean energy tax credits, which are on the chopping block in the big budget reconciliation bill in Congress.

The nonpartisan think tank Energy Innovation said repealing these credits could lead to a loss of 26,000 jobs in Pennsylvania by 2030 and even more by 2035.

Robbie Orvis, senior director of modeling and analysis for Energy Innovation, said losing tax credits from the Inflation Reduction Act would make clean energy manufacturing and clean power projects less viable and increase household energy bills.

"In Pennsylvania in particular, we found that the loss of the clean energy tax credits would lead to $60 per year in higher household energy bills by 2030 growing to $80 per year by 2035," Orvis reported. "That amounts to more than $2 billion more in spending on energy for Pennsylvanians between 2025 and 2035."

He added the lost incentives would also mean $5 billion in lost state gross domestic product by 2030, and $6 billion by 2035. In Congress, Senators are divided over whether to keep the Biden-era tax credits.

Aaron Nichols, solar policy and research specialist for the Bucks County system installer Exact Solar, said solar allows thousands of Pennsylvania homes and businesses to save on energy bills and gives them a choice beyond big utilities. The tax credits make the switch easier.

"Solar energy made up 66% of the new electricity-generating capacity added to the grid last year," Nichols pointed out. "As people have taken advantage of these incentives, the solar industry has grown, creating thousands of good-paying jobs."

Mike Zimmerman, senior attorney for electrification at the advocacy group EDF Action in Pittsburgh, said they have seen more than $1 billion in clean energy investments in the state from battery manufacturing in Turtle Creek to solar manufacturing in Leetsdale and grid technology production in Williamsport. He added 27 gigawatts of mostly solar, wind and battery projects are waiting to connect to the grid.

"These facilities are doing much more than creating jobs," Zimmerman emphasized. "They're cutting energy costs for families, meeting growing energy demand and reducing the pollution that threatens our health and our state's natural resources."

Backers of keeping the clean energy tax credits said repealing them would lead to more fossil fuel use, which worsens air quality and is linked to serious health problems.
