SEPA Electricity Demand and Generation Mix

Hourly and daily grid operator data for Southeastern Power Administration. Operator data is hourly and provisional, and may be revised.

SEPA is a generation only balancing authority: it reports generation and interchange but no demand.

Key Facts

  • SEPA is a balancing authority in the United States, part of the EIA Southeast region.
  • SEPA generated 1.44 TWh of electricity in 2025.
  • Hydro supplied 100.0% of SEPA's generation in 2025.

Generation by Source

Net interchange-196 MWnet imports

EIA publishes generation by source 10 or more hours after demand, so this hour can be earlier than the latest demand hour. Net interchange is positive when SEPA exports.
