Caveats

  • The source publishes sales in megawatthours; values here are divided by 1000 to store gigawatthours.
  • Total retail sales includes each geography's 'Other' sector sales (1990 to 2002); those are not broken out in the by-sector breakdown.
  • Figures cover the Total Electric Industry (all provider types combined), not any single provider type.
