Electricity Monthly Update

With Data for April 2024 Release Date: June 26, 2024 Next Release Date: July 24, 2024

Electric Power Sector Coal Stocks: April 2024


Total U.S. coal stockpiles increased by 2.5% to 137 million tons compared to the previous month. This month-over-month increase in coal stockpiles is normal during a shoulder month like April, when coal power plants build up their stockpiles for use in the summer months when the demand for electricity is much 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 145 days of forward-looking days of burn in March 2024 to 132 days of burn in April 2024. For subbituminous units largely located in the western United States, the average number of days of burn also decreased, going from 144 days of burn in March 2024 to 132 days of burn in April 2024.
