Electricity Monthly Update

With Data for January 2024 Release Date: March 26, 2024 Next Release Date: April 24, 2024

Electric Power Sector Coal Stocks: January 2024


Total U.S. coal stockpiles decreased 7.4% to 122 million tons compared to the previous month. In the winter months each year, U.S. coal stockpiles decrease as coal power plants increase operations 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 154 days of forward-looking days of burn in January 2023 to 148 days of burn in January 2024. For subbituminous units largely located in the western United States, the average number of days of burn also decreased, going from 177 days of burn in December 2023 to 156 days of burn in January 2024.
