Electricity Monthly Update

With Data for October 2025 Release Date: December 23, 2025 Next Release Date: January 23, 2026 Corrections/Revisions

Electric Power Sector Coal Stocks: October 2025


Total U.S. coal stockpiles increased by 3.4% to 109 million tons compared to the previous month. This month-over-month increase in coal stockpiles is normal when the country enters the fall months and coal power plants begin to build up their stockpiles 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 120 days of forward-looking days of burn in September 2025 to 118 days of burn in October 2025. For subbituminous units largely located in the western United States, the average number of days of burn in October 2025 remained flat at 116 days of burn compared to the previous month.
