Electric Power Sector Coal Stocks: August 2016
In August, U.S. coal stockpiles decreased to 163 million tons, down 5.3% from the previous month. Although U.S. coal stockpiles are at their lowest levels all year due to the normal, seasonal draw-down of coal stockpiles that occurs each summer, the coal stockpiles level reached in August 2016 was still 3.8% above the level observed last year, when coal stockpiles were at 157 million tons.
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 87 days of burn in July to 90 days of forward-looking days of burn in August. For subbituminous units largely located in the western United States, the average number of days of burn increased, going from 80 days in July to 84 days in August.
