Electricity Monthly Update
With Data for December 2013 | Release Date: Feb. 21, 2014 | Next Release Date: Mar. 21, 2014
Electric Power Sector Coal Stocks: December 2013
In December 2013, total coal stocks decreased 5.0 percent from the previous month. This follows the normal seasonal pattern for this time of year as the country begins to consume more coal for electricity generation during the winter months. Compared to last December, coal stocks decreased 20.1 percent. This occurred because coal stocks in December 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 from 71 days the previous month to 63 days in December 2013, while the total subbituminous supply decreased from 56 days in November 2013 to 48 days in December 2013.
