Electric Power Sector Coal Stocks: June 2015
In June, U.S. coal stockpiles decreased to 168 million tons, down 4% from the previous month. This decrease in May-to-June coal stockpiles follows the normal seasonal pattern whereby coal stockpiles begin to decrease as the U.S. enters the summer months. Despite this decrease, 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 declined slightly from 74 days to 73 days of forward-looking days of burn estimates. For subbituminous units largely located in the western United States, the average number of days of burn had a much larger decrease, going from 71 days in May to 65 days in June. The percentage of bituminous and subbituminous coal-fired capacity having less than 30 days of burn increased from the previous month, going from 5.3% in May to 9.2% in June. This is a much lower percentage than last June, when almost 24% of units had less than 30 days of burn.
