Electricity Monthly Update
With Data for September 2013 | Release Date: Nov. 22, 2013 | Next Release Date: Dec. 20, 2013
Electric Power Sector Coal Stocks: September 2013
In September 2013, total coal stocks decreased 1.2 percent from the previous month. This decrease in month-to-month coal stocks deviates from the normal seasonal pattern, as there has been a slight increase in total coal stocks from August to September over the past several years. Compared to last September, coal stocks decreased 14.9 percent. This occurred because coal stocks in September 2012 were at an extremely high level.
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. The total bituminous supply decreased slightly from 87 days the previous month to 86 days in September 2013, while the total subbituminous supply increased slightly from 63 days in August 2013 to 64 days in September 2013.
