Electricity Monthly Update

With Data for July 2026 Release Date: September 24, 2026 Next Release Date: October 23, 2026

Electric Power Sector Coal Stocks: July 2026


Total U.S. coal stockpiles decreased by 8.0% 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 117 days of forward-looking days of burn in June 2026 to 127 days of burn in July 2026. For subbituminous units largely located in the western United States, the average number of days of burn also increased, going from 116 days of burn in June 2026 to 119 days of burn in July 2026.
