Electricity Monthly Update

Electric Power Sector Coal Stocks: November 2015
In November, U.S. coal stockpiles increased to 189 million tons, up 7% from the previous month. This increase in October-to-November coal stockpiles follows the normal seasonal pattern whereby coal stockpiles get built up during the fall months. Coal stockpiles are still at relatively high levels due to a loss in market share to natural gas in all regions of the country.
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 October to 88 days of forward-looking days of burn in November. For subbituminous units largely located in the western United States, the average number of days of burn increased, going from 80 days in October to 85 days in November. The percentage of bituminous and subbituminous coal-fired capacity having less than 30 days of burn decreased slightly from 5.5% in October to 4.7% in November.
