EIA-930Hourly electricity demand, generation and interchange. Reported values are the authority’s filings. EIA-adjusted values account for non-physical commercial transfers; EIA-imputed values replace missing or anomalous reports with estimates. Every demand report EIA replaced is left out of every sum and mean here; a replaced generation or interchange report is left out when it is whose magnitude is at least 1.5 times the largest unreplaced magnitude of that authority and year, since zeros and imports are real there. The estimate is never used in its place.Definition ↗ reports for this authority, 2023-10 to 2026-09 (UTC months). Mean MW over the hours reported; a dot marks a month with under 90% of hours.
Reported demand; every hour EIA marked is left out and counted, and EIA's adjusted and imputed series are in the download table, never substituted here.
Monthly mean demand, net generation and total interchange (positive = export) as this authority reported them; months with no report are gaps, not zero.

EIA-930 hourly reports summarized by UTC month; means cover the kept reported hours and carry their coverage, leaving out the flagged hours EIA marked (hours_flagged); the 2024Q3 fuel taxonomy change appears as new source codes
A reporting assignment, not a retail supply relationship.
Display names verified against each organization's own website; EIA legal names retained as aliases
A display name is the name an organization uses for itself; the EIA name stays searchable and on the record. Each row cites the page that shows the name.
