Electric Power Sector Coal Stocks: June 2014

 



Total U.S. coal stocks decreased by 3.3 million tons compared to the previous month. This decrease in coal stocks follows the seasonal pattern from May to June as power plants begin to consume more coal to meet increased electricity demand during the summer months. Furthermore, compared to the previous June, total U.S. coal stocks are down 22.1 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 51 days the previous month to 49 days in June 2014, while the total subbituminous supply decreased from 46 days in May 2014 to 42 days in June 2014.
