THE DEFAULT RESIDENTIAL RATE in Ameren Missouri's territory. Seasonal, and NOT time-of-use.
$9.19/month, being a $9.00 customer charge PLUS a separate $0.19 Low-Income Pilot Program Charge. Two lines, not one.
THE WINTER BLOCK DECLINES: 0.1062 for the first 750 kWh and 0.0714 above it. Almost every other tiered residential rate in this catalogue increases with usage; assuming that here would overcharge every high-use winter month and still look ordinary.
Summer is June to September at 0.156/kWh flat; winter is October to May.
THREE RIDERS APPLY and the schedule names them: FAC (fuel and purchased power), EEIC (energy efficiency) and RESRAM (renewable energy standard), totalling 0.012915/kWh. The Tax Adjustment is excluded, being jurisdiction-specific.
THE FAC IN FORCE COVERS JUNE 1 TO SEPTEMBER 30 2026 ONLY. Ameren's recovery periods are February-September and October-May, so the winter FAC is not filed yet. The winter figures here carry a summer FAC and will move on October 1. No successor probe is needed: Ameren republishes the FAC at the same URL, so the ordinary content hash sees it change.
RIDER RESRAM IS SERVED FROM A FILE NAMED 'blanksheets'. It is not blank - it is Sheet No. 93, the full rider, at $0.00207/kWh. A filename is not a fact about its contents.
NOT IN THE SURVEYED TOP THIRTY. Union Electric is a separate EIA operating company from Ameren Illinois and was never surveyed, so this is real coverage that must not move the '% of the top-30' figure - the same convention as Dominion Energy South Carolina.
NOT ENCODED: the Residential Smart Saver and Evening/Morning Saver time-of-use alternatives, which appear on the same sheet.
