About these numbers

Source
U.S. Energy Information Administration, Annual Electric Power Industry Report (Form EIA-861), 2024 data. The monthly bill and price per kWh are computed by CheckedHome from EIA residential revenue and sales. View the source. Synced from EIA on .
Self-reported
Utilities report these figures to EIA themselves; EIA does not audit every submission, and outages from recent months appear only in the next annual release.
Major storm days
Outage figures can be shown with or without Major Event Days (severe storms). We show both on utility pages and never cherry-pick.
A correction?
We republish the official record verbatim. If a figure looks wrong, see Corrections; we re-check it against EIA.
Reporting standard
Southern Maryland Elec Coop Inc reports under the IEEE 1366 method. The standard used is shown so figures are not mixed silently.
Counties served
Calvert, Charles, Prince Georges, St Marys.

We show EIA values as published, reformatting only for a consistent house style. How we display these figures.
