Electric Power Sector Coal Stocks: May 2014

 



Total U.S. coal stocks increased by 7.9 million tons compared to the previous month as the electric industry continues its spring build-up of coal stocks at power plants. However, compared to the previous May, total U.S. coal stocks are down 22.9 percent.

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. The total bituminous supply decreased from 55 days the previous month to 51 days in May 2014, while the total subbituminous supply decreased from 50 days in April 2014 to 46 days in May 2014.
