Electric Power Sector Coal Stocks: September 2017

 



In September 2017, U.S. coal stockpiles decreased to 140 million tons, down 1.5% from the previous month. This decrease in total coal stockpiles is a normal occurence during the summer months when demand for electricity is greater.

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 89 days of burn in August 2017 to 92 days of forward-looking days of burn in September 2017. For subbituminous units largely located in the western United States, the average number of days of burn increased from 79 days in August 2017 to 84 days in September 2017.
