Electric Power Sector Coal Stocks: March 2016
In March, U.S. coal stockpiles increased to 194 million tons, up nearly 3% from the previous month. The large departure from the winter draw-down in coal stocks occurred because of the extremely warm temperatures experienced throughout the country in March 2016 (and the winter as a whole) and also becaue coal continues to lose 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 decreased from 99 days of burn in February to 97 days of forward-looking days of burn in March. For subbituminous units largely located in the western United States, the average number of days of burn decreased, going from 105 days in February to 102 days in March. Both average number of days of burn for bituminous units and subbituminous units are still at extremely high levels.
