Remember when coal was supposed to be dead? Turns out those obituaries might have been written a bit early. Coal-fired power is getting an unexpected lease on life in the United States, and the reason is pretty straightforward: we need more electricity, and we need it now.
The surge in power demand is forcing utilities and policymakers to make a practical choice between sticking to retirement schedules and keeping the lights on. Reliability is winning.
"Coal is, quite simply, America's largest energy asset," Peabody Energy Corporation (BTU) CEO James Grech said during the company's latest earnings call. "More than that, America has more energy in its coal than any nation has in any one energy source."
Grech, who recently took the helm of the reconstituted National Coal Council, argues it would be "irresponsible to not use this unique asset for the benefit of the American people." His pitch is basically that coal offers strategic value because it's abundant, sitting right here at home, and can support long-term energy security.
The AI Power Problem
Here's what's driving this shift: electricity consumption is climbing fast, pushed higher by artificial intelligence, data centers, and advanced manufacturing. BloombergNEF estimates that U.S. data centers alone could consume up to 106 GW of power by 2035, compared with about 35 GW in 2024. That's a massive jump in just over a decade.
Utilities are responding by keeping coal plants online. Southern Company chief executive Chris Womack recently said the utility would extend coal plants "as long as we can because we need those resources on the grid," according to Yale. At least 15 coal plants have already delayed planned retirements, and some of those delays are indefinite.
Running Below Capacity
Peabody Chief Commercial Officer Malcolm Roberts noted that coal generation jumped about 13% year-over-year, which was more than expected. But there's still plenty of headroom. Existing coal plants ran at just 42% of capacity in 2024, compared to 72% at historical peak levels.
That's the key insight here: extending the life of existing plants could significantly boost electricity supply without the delays that come with building new infrastructure. Raising utilization rates could add up to 10% of total U.S. power generation compared with 2024 levels.
"Renewables continue to be built out, but don't solve the problem of data centres and factories that need 24/7 generation," Roberts explained. Gas plants face development backlogs, and nuclear projects involve long permitting and construction timelines. Meanwhile, he pointed to research showing that adding new solar capacity could cost 10 times as much.
This isn't just an American phenomenon. In Australia, the planned closure of the country's largest coal-fired power station, Eraring, has been pushed back from 2027 to 2029. Experts warned that the grid wasn't ready and blackouts were possible.
Still, this doesn't mean coal is making a permanent comeback. The International Energy Agency expects global coal demand for power generation to plateau and then ease slightly through 2030. Think of this as a bridge strategy rather than a long-term plan.
BTU Price Action: Peabody Energy shares were up 0.48% at $38.01 during premarket trading on Tuesday. The stock is approaching its 52-week high of $39.95.
