Electricity Monthly Update

With Data for February 2025 Release Date: April 24, 2025 Next Release Date: May 23, 2025

Electric Power Sector Coal Stocks: February 2025


Total U.S. coal stockpiles decreased by 5.9% to 107 million tons compared to the previous month. This month-over-month decrease in coal stockpiles is normal during the winter months when coal power plants operate more frequently to meet winter electricity demand.

Days of burn



The average number of days of burn held at electric power plants is a forward-looking estimate of coal supply given a power plant's current stockpile and past consumption patterns. For bituminous units largely located in the eastern United States, the average number of days of burn decreased from the previous month, going from 132 days of forward-looking days of burn in January 2025 to 121 days of burn in February 2025. For subbituminous units largely located in the western United States, the average number of days of burn also decreased, going from 147 days of burn in January 2025 to 133 days of burn in February 2025.
