1/ Data on purchases from nonutilities were not collected on the Form
EIA-861.
2/ These values are not measured; however, they represent losses and
unaccounted for energy. These values are calculated in order
that source and disposition of energy are equivalent. Notes:
· Data are final. ·
Annual net generation data shown here should only be used in comparison
with other Form EIA-861 data. Differences in this net generation
data and net generation reported on the Form EIA-759, "Monthly Power
Plant Report," (Table 1) occur due to the time frame in reporting.
Since the components of net generation are provided monthly by the
Form EIA-759 by prime mover and energy source, the Form EIA-759 is
used as the official Energy Information Administration source for
net generation. · Totals may not
equal sum of components because of independent rounding. ·
"Sales to Ultimate Consumers" for the years 1996 through 2000 do not
include sales by retail power marketers in state-level deregulated
markets. 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. · Due to the complexity
of electric power transactions that involve specifics of contracts,
simultaneous energy transactions, the unintended receipt and delivery
of energy (inadvertent flow), and losses, uniformity in reporting
the classification and quantity of each transaction among utilities
may not exist. Source:
