Electric Power Sector Coal Stocks: July 2016

 



In July, U.S. coal stockpiles decreased to 172 million tons, down 7.4% from the previous month. As a whole, U.S. coal stockpiles have decreased 22.6 million tons from this year's high of 194 million tons in March. However, U.S. coal stockpiles are still at relatively high levels becaue coal continues to lose market share to natural gas in most regions of the country.

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 86 days of burn in June to 87 days of forward-looking days of burn in July. For subbituminous units largely located in the western United States, the average number of days of burn increased, going from 79 days in June to 80 days in July.
