Electricity Monthly Update

With Data for April 2025 Release Date: June 25, 2025 Next Release Date: July 24, 2025

Electric Power Sector Coal Stocks: April 2025


Total U.S. coal stockpiles increased by 3.9% to 116 million tons compared to the previous month. This month-over-month increase in coal stockpiles is normal during April when coal power plants begin to build up their stockpiles for use during the summer months when electricity demand is higher.

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 114 days of forward-looking days of burn in March 2025 to 106 days of burn in April 2025. For subbituminous units largely located in the western United States, the average number of days of burn also decreased, going from 124 days of burn in March 2025 to 112 days of burn in April 2025.
