These values are calculated in order that source and disposition of energy are equivalent.
Data are final.
Annual net generation data shown here should only be used in comparison with other Form EIA-861 data. Totals may not equal sum of components because of independent rounding. For further information on these transactions see Electric Sales and Revenue for those years. The source and disposition of electricity represent the total volume of energy transactions between utilities. These data should not be summed as they are the aggregation of data reported for each utility and could be double counted due to the nature and types of electricity trade.
