Purchase Report

Industry Summary

The 313 Coal producers in the US sell coal to electric utilities, industrial facilities, steel manufacturers, and energy marketing firms or traders. Exports are also an important market for US coal producers. Coal mines are classified by their mining method and the type of coal they mine. Surface mining is the predominant mining method, particularly in western states, while underground mining is often used in eastern states. Coal varies by heat content, ranging from lignite (the lowest grade) to sub-bituminous, bituminous, and anthracite (the highest grade).

Environmental Compliance

Coal producers are directly impacted by a wide range of environmental regulations that affect the permitting, operation, and reclamation of mining sites.

Competition for Electric Power Generation

According to the US Energy Information Administration (EIA), about 91% of US coal consumption is used for electric power generation, and coal supplies 17% of US electricity generation.


Recent Developments

Jul 27, 2025 - Longer Life Expectancy
  • A new Wood Mackenzie report predicts an extended sunset period for coal as a US power source. The report found that rising electricity demand and a slowdown in the buildout of alternative power generation sources could extend the use of coal globally and displace 2,100 GW of gas and renewables by 2050. While in the US coal is more expensive than gas or solar and storage, the cost of building new gas power plants has nearly doubled and long-duration energy storage technology isn’t mature enough to convert solar and wind into true “baseload” resources, per the report. It’s also becoming more expensive to replace aging coal plants with gas and renewables, causing “sticker shock” for power producers looking to switch. The report blames tariffs, reshoring, and infrastructure delays for pushing up the cost of new solar and a near-doubling of costs for new gas power plants.
  • The scheduled retirement dates of dozens of coal-fired US power plants are being canceled as growth in energy demand and changes in environmental regulations keep the plants online, The New York Times reports. Wyoming’s 66-year-old Dave Johnston Power Plant – one of the oldest in the US that’s situated on the edge of the nation’s largest coal mine – was slated to close in 2027, but its planned retirement was canceled. According to a NYT analysis, utilities have extended the life of nearly a third of coal units with planned retirement dates. A 2023 study by Energy Innovation showed that 99% of operating US coal plants were more expensive to operate than replacement by local wind, solar, and energy storage resources. Some 780 coal units have retired since 2000 leaving the US with about 400, according to new data from the Global Energy Monitor cited by NYT.
  • Cuts to the National Institute for Occupational Safety and Health (NIOSH) by the Department of Government Efficiency, or DOGE, threaten miners’ safety just as the Trump administration seeks to expand mining in the US, NPR reports. The president of the United Mine Workers of America (UMWA) condemned the cuts, stating “This is not just an attack on jobs. This is an attack on the very foundation of worker safety in the United States of America.” UMWA president said the dismantling of the Respiratory Disease Division at NIOSH eliminates the nation’s leading defense against black lung disease and other respiratory illnesses that afflict miners. In March, President Trump signed an executive order fast tracking permitting and expanding mining in the US. The cuts at NIOSH followed soon after. More mining means more miners to protect. However, miners' protections are being stripped away, according to UMWA.
  • Producer prices for coal mining firms rose 1.5% in June compared to a year ago, after rising 4.4% in the previous June-versus-June annual comparison, according to the latest US Bureau of Labor Statistics data. Employment by coal mines shrank 5.3% year over year in June, while average wages at mining firms rose 2.9% YoY in May to $35.85 per hour, BLS data show. Competition from cleaner alternative energy sources – notably natural gas for electricity – has led to declining demand for coal and coal miners, whose numbers are down nearly 40% over the past decade, according to BLS figures.

Industry size & Structure

The average US coal mining company operates 1-2 mines, employs about 136 workers, and generates $89 million in annual revenue.

    • The US coal mining industry comprises about 313 companies operating 501 mines, employing 42,500 workers, and generating $28 billion in annual revenue.
    • Electric power generation accounts for 91% of US coal consumption.
    • The US has a total productive capacity of almost 847 million short tons of coal. Nearly two-thirds (62%) of US coal production is from surface mines, while underground mines account for 38%.
    • The industry is highly concentrated: the top 20 companies account for 76% of annual production.
    • The largest US coal producers are Peabody Energy, Core Natural Resources, Navajo Transitional Energy Company (NTEC), Alliance Resource Partners, and Acnr Holdings.
    • The largest coal producing states are Wyoming, West Virginia, Pennsylvania, Illinois, and Montana.
    • The largest underground mine in the US is the Bailey Mine in Pennsylvania, producing over 11.1 million short tons annually. The largest surface mine in the US is Wyoming’s North Antelope Rochelle Mine, producing over 62 million short tons annually.
    • According to the Bureau of Labor Statistics, employment by US coal mines is projected to fall 43.3% between 2022 and 2032, the sharpest decline of all industries.
