Electric Power Sector Coal Stocks: December 2016
In December, U.S. coal stockpiles decreased to 164 million tons, down 4.8% from the previous month. This decrease in total coal stockpiles follows the normal seasonal pattern whereby coal stockpiles are drawn down during the winter months.
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 decreased from 85 days of burn in November to 80 days of forward-looking days of burn in December. For subbituminous units largely located in the western United States, the average number of days of burn remained flat from the previous month at 90 days .
