| * = 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 “*”.) | |||||||||||
| NM = Not meaningful due to large relative standard error or excessive percentage change. | |||||||||||
| Notes: • Totals may not equal sum of components because of independent rounding. • Percentage difference is calculated before rounding. • See Glossary for definitions. • Negative generation denotes that electric power consumed for plant use exceeds gross generation. • Values for 2010 are final. Values for 2011 are preliminary. – See Technical Notes for a discussion of the sample design for the Form EIA-923. | |||||||||||
