What this figure does and does not include
Transcription notes recorded when this tariff was encoded, including anything deliberately left out.
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 0.008425/kWh. The Tax Adjustment is excluded, being jurisdiction-specific.
THE FAC IN FORCE COVERS 2026-10-01 THROUGH 2027-01-31. Ameren re-sets it for each recovery period and republishes it at the same URL, so the ordinary content hash sees it change. From 1 October 2026 it is $0.00445/kWh at secondary voltage, down from $0.00894 for June to September: the new period's own adjustment is $0.00000 and only the prior period's $0.00421 carries.
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.
A SEPARATE EIA OPERATING COMPANY FROM AMEREN ILLINOIS. Same brand, different company, different commission - Union Electric files in Missouri and Ameren Illinois in Illinois, and encoding one says nothing about the other. This note used to add that it was outside the surveyed population and must not move the coverage figure; that stopped being true on 2026-08-29, when the population became a rank-based rule and Union Electric qualified on it at rank 33. It is counted now.
NOT ENCODED: the Residential Smart Saver and Evening/Morning Saver time-of-use alternatives, which appear on the same sheet.
