Caveats

  • This is EIA's residual (supply minus sales, direct use, exports and losses), not a direct measurement of interstate power flows.
  • The source publishes megawatthours; values here are divided by 1000 to store gigawatthours.
  • Each state and the District of Columbia publishes its own workbook in the same format; Idaho's is linked above, and every other state's is the same file with its own two-letter postal abbreviation in place of ID.
