  * = Value is less than half of the smallest unit of measure (e.g., for values with no decimals, the smallest unit is "1" then values under 0.5 are shown as "*".)
  Notes: See Glossary for definitions. Relative Standard Error is designed to indicate error due to sampling.  However, nonsampling error is important for all surveys, census or sample.  See Technical Notes for further information. Values for 2008 are preliminary.
  Sources: Energy Information Administration, Form EIA-906, "Power Plant Report;" Beginning with 2008 data, the Form EIA-923, "Power Plant Operations Report," replaced the following: Form EIA-906, "Power Plant Report;" Form EIA-920, "Combined Heat and Power Plant Report;"  Form EIA-423, "Monthly Cost and Quality of Fuels for Electric Plants Report;" and  Federal Energy Regulatory Commission, FERC Form 423, "Monthly Report of Cost and Quality of Fuels for Electric Plants."
