Electricity Monthly Update

With Data for July 2025 Release Date: September 23, 2025 Next Release Date: October 24, 2025

Electric Power Sector Coal Stocks: July 2025


Total U.S. coal stockpiles decreased by 6.6% to 109 million tons compared to the previous month. This month-over-month decrease in coal stockpiles is normal during the summer months when coal power plants operate more and use up their stockpiles to meet summer 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 increased from the previous month, going from 114 days of forward-looking days of burn in June 2025 to 121 days of burn in July 2025. For subbituminous units largely located in the western United States, the average number of days of burn also increased, going from 104 days of burn in June 2025 to 111 days of burn in July 2025.
