Weekly Coal Production
Data for week ended: March 21, 2015 | Release date: March 26, 2015 | Next release date: April 2, 2015
Note: As of January 8, 2015, EIA began using a new methodology for estimating weekly coal production. The change in methodology resulted in an overall improvement in precision and reduction in bias at the national and regional levels. This change also eliminated existing system issues and greatly reduced the amount of resources needed to produce the report each week. However, in some states, the level of precision declined as a result of the methodology change. Alternatively, in some states, the level of precision improved. The accompanying spreadsheet, "Comparison Model Performance vs Actual," contains a statistical comparison of the previous vs. new methodology with actual coal production for the past five years. Users are encouraged to review these results in order to make informed use of the state-level estimates. Please note: comparisons were done at the quarterly level, as this is the shortest interval for which actual coal production data exist; actual weekly or monthly coal production data are not available from any known source.
In response to customer feedback, EIA resumed publishing the weekly state level estimates beginning with the Weekly Coal Production report published February 12, 2015. EIA also provided weekly state level estimates covering the entire period since the change in methodology was implemented.
For the week ended March 14, 2015:
- Estimated U.S. coal production totaled approximately 18.2 million short tons (mmst)
- This production estimate is 1.7% lower than last week's estimate and 7.9% lower than the production estimate in the comparable week in 2014
- East of the Mississippi River coal production totaled 7.6 mmst
- West of the Mississippi River coal production totaled 10.6 mmst
- U.S. year-to-date coal production totaled 210.9 mmst, 2.8% lower than the comparable year-to-date coal production in 2014
