U.S. officials in coming days are set to hold the government's biggest coal sales in more than a decade, offering 600 million tons from publicly-owned reserves next to strip mines in Montana and Wyoming.

The sales are a signature piece of President Donald Trump's ambitions for companies to dig more coal from federal lands and burn it for electricity. Yet most power plants served by those mines plan to quit burning coal altogether within 10 years, an Associated Press data analysis shows.

Three other mines poised for expansions or new leases under Trump also face declining demand as power plants use less of their coal and in some cases shut down, according to data from the U.S. Energy Information Administration and the nonprofit Global Energy Monitor.

Those market realities raise a fundamental question about the Republican administration's push to revive a heavily-polluting industry that's long been in decline: Who's going to buy all that coal?

The question looms over the Trump administration's enthusiastic embrace of coal, a leading contributor to climate change. It also shows the uncertainty inherent in inserting those policies into markets where energy-producing customers make long-term decisions with massive implications, not just for their own viability but for the future of the planet, in an ever-shifting political landscape.

Rushing to approve projects

The upcoming lease sales in Montana and Wyoming are in the Powder River Basin, home to the most productive U.S. coal fields.

They're expected to go forward beginning Monday despite the government shutdown. The Trump administration exempted from furlough workers who process fossil fuel permits and leases.

Democratic President Joe Biden last year moved to block future coal leases in the region, citing their potential to make climate change worse. Burning the coal from the two leases being sold in coming days would generate more than 1 billion tons of planet-warming carbon dioxide, according to a Department of Energy formula.

Trump rejected climate change as a “con job” during a September 23 speech to the United Nations General Assembly, an assessment that puts him at odds with scientists. He praised coal as “beautiful" and boasted about the abundance of U.S. supplies while deriding solar and wind power. Administration officials said Wednesday that they were canceling $8 billion in grants for clean energy projects in 16 states that voted for Democrat Kamala Harris in 2024.

In response to an order from Trump on his first day in office, coal lease sales that had been shelved or stalled were revived and rushed to approval, with considerations of greenhouse gas emissions dismissed. Administration officials have advanced coal mine expansions and lease sales in Utah, North Dakota, Tennessee and Alabama, in addition to Montana and Wyoming.

Interior Secretary Doug Burgum said Monday that the administration is opening more than 20,000 square miles of federal lands to mining. That's bigger than New Hampshire and Vermont combined.

The administration also sharply reduced royalty rates for coal from federal lands, ordered coal-fired power plants in Michigan and Pennsylvania to stay open past planned retirement dates, and pledged $625 million to recommission or modernize coal plants amid growing electricity demand from artificial intelligence and data centers.

“We're putting American miners back to work,” announced Burgum, flanked by coal miners and Republican politicians. “We've got a demand curve coming at us in terms of the demand for electricity that is literally going through the roof.”

Coal demand plummets

AP's finding that power plants served by mines on public lands are burning less coal reflects an industrywide decline that began in 2007.

Energy experts and economists weren't surprised. They expressed doubt that coal would ever reclaim dominance in the power sector. Interior officials did not respond to questions about future demand for coal from public lands.

But it will take time for more electricity from planned natural gas and solar projects come online. That means Trump's actions could give a short-term bump to coal, said Umed Paliwal, an expert in electricity markets at Lawrence Berkeley National Laboratory.

“Eventually coal will get pushed out of the market,” Paliwal said. “The economics will just eat the coal generation over time.”

The coal sales in Montana and Wyoming were requested by a Navajo tribe-owned corporation. The Navajo Transitional Energy Co. (NTEC) has been one of the largest industry players since buying several major mines in the Powder River Basin during a 2019 bankruptcy auction. Those mines supply 34 power plants in 19 states.

Twenty-one of the plants are scheduled to stop burning coal in the next decade. They include all five plants using coal from NTEC's Spring Creek mine in Montana.

In filings with federal officials, the company said the fair market value of 167.5 million tons of federal coal next to the Spring Creek mine was just over $126,000.

That's less than one-tenth of a penny per ton, a fraction of what coal brought in its heyday. Processing fees alone for the sale would be more than twice that amount, according to government documents. By comparison, one of the last large-scale lease sales proposed in the Powder River Basin drew a bid of $35 million in 2013. It was rejected by federal officials as too low.

NTEC said the low value was supported by prior government reviews predicting fewer buyers for coal. The company said taxpayers would benefit in future years from royalties on any coal mined.

“The market for coal will decline significantly over the next two decades. There are fewer coal mines expanding their reserves, there are fewer buyers of thermal coal and there are more regulatory constraints,” the company said.

In central Wyoming on Wednesday, the government will sell 440 million tons of coal next to NTEC’s Antelope Mine. Sixteen of the 29 power plants using coal from the Antelope Mine are scheduled to stop burning coal by 2035.

Among them is the Rawhide plant in northern Colorado. It’s due to quit coal in 2029, but will keep making electricity with natural gas and 30 megawatts of solar panels.

Aging plants and optimism

The largest U.S. coal company has offered a more optimistic take on coal's future of late. Since new nuclear and gas plants are still years away, Peabody Energy declared in September that demand for coal in the U.S. could rise by 250 million tons annually — almost a 50% increase from current volumes.

Peabody’s projection was based on the premise that existing power plants would burn more coal. That amount, known as plant capacity, dropped by about half in recent years.
