Electric Power Sector Coal Stocks: January 2017

 



In January, U.S. coal stockpiles decreased to 157 million tons, down 4% from the previous month. This decrease in total coal stockpiles follows the normal seasonal pattern whereby coal stockpiles are drawn down during the winter months.

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 80 days of burn in December to 90 days of forward-looking days of burn in January. For subbituminous units largely located in the western United States, the average number of days of burn increased from 90 days in December to 99 days in January.
