Electric Power Sector Coal Stocks: October 2016

 



In October, U.S. coal stockpiles increased to 164 million tons, up 3.4% from the previous month. This increase in total coal stockpiles follows the normal seasonal pattern whereby coal stockpiles begin to build-up during the autumn 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 92 days of burn in September to 86 days of forward-looking days of burn in October. For subbituminous units largely located in the western United States, the average number of days of burn remained unchanged at 87 days in October.
