Electric Power Sector Coal Stocks: September 2016
In September, U.S. coal stockpiles decreased to 158 million tons, down 1.4% from the previous month. This small decrease in total coal stockpiles deviates slightly from the normal seasonal pattern whereby historically, coal stockpiles have begun to increase in September.
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 to 92 days of forward-looking days of burn in September. For subbituminous units largely located in the western United States, the average number of days of burn increased, going from 84 days in August to 87 days in September.
