VERIFIED AGAINST ENTERGY'S OWN ITEMISED SAMPLE BILL. Entergy publishes a 1,000 kWh sample for each operating company listing every schedule with its rate and a total, linked from the company's /residential/price page. These figures reconstruct it to the cent, and the build script refuses to write this file if they stop doing so.
PUBLISHED RIDER IS NOT THE SAME AS RIDER ON THE BILL. An Entergy tariff index lists dozens of schedules; roughly a dozen reach a residential bill. The rest are other classes, other programmes, enrolment-only credits, or dormant filings left on file at zero. Nothing in the index distinguishes them, which is why the sample bill is the source of truth for WHICH schedules apply and the tariff sheets only for their values.
THE FILED RATE SHEET IS SEVEN YEARS OLD AND THAT IS CORRECT. Schedule RS is still the original sheet effective 1 February 2019, at $8.40 and 6.990c/kWh in winter. It has not been revised because Rider FRP re-prices it annually instead, and the current FRP rate is 52.4369%. Encoding the RS sheet alone would understate a bill by about a third - and nothing on the sheet warns you.
THE PERCENTAGE BASE IS THE BASE RATES ONLY. Rider FRP (+52.4369%) and Rider TA (-1.17598%) are parallel percentages of the customer charge plus the energy charge. They do not compound with each other and no rider sits inside either base. Entergy's sample bill shows the FRP computed on $82.32, which is exactly $8.40 + $73.92.
RIDER GAJA IS NOT GROSSED UP, despite being absent from the FRP exclusion list. The sample bill shows it as a flat $0.00574/kWh adder, and its own Attachment 2 derives the rate as revenue requirement divided by billing units - a 52% gross-up would over-recover by about $23m against a rider that is subject to Commission review and refund. The exclusion list, effective 2 January 2026, simply has not caught up with a rider filed on 2 December 2025. Cost of getting this wrong: $3.01 a month.
RIDER IRCR IS EXPIRED BUT STILL LISTED AS MANDATORY. The internal restructuring credit (-0.5031%) stopped billing with cycle 21 of December 2024, and Attachment A was never renewed - yet IRCR still appears in the Table of Riders (8th revised, effective 2 December 2025) and in the FRP exclusion list. It is absent from the sample bill. This is the Arkansas version of the Texas DPBF trap: a real document, currently posted, that does not reach a bill.
THE TIER DIRECTION REVERSES WITH THE SEASON. June-September INCLINES - 7.392c for the first 1,500 kWh then 9.593c. October-May DECLINES - 6.990c for the first 1,000 kWh then 5.154c. So heavy usage is penalised in summer and rewarded in winter, and the tier threshold moves too. Alabama Power has the same shape.
NEITHER TIER IS CONFIRMED BY A PUBLISHED EXAMPLE. Every sample bill Entergy Arkansas publishes is for 1,000 kWh, which never crosses the 1,500 kWh summer boundary and sits exactly on the 1,000 kWh winter one. The above-tier rates come from the rate sheet alone.
NOT ENCODED: the Low/Level Use rate (7.0-8.99c summer, 6.4-4.7c winter), which is materially cheaper but cannot be selected from a month's kWh. It requires twelve months of history at the same residence, annual consumption at or below 6,000 kWh, and a summer peak no more than 1.2 times the winter peak.
EXCLUDED: Rider MFA, the municipal franchise adjustment, which runs from 0% to 6% by town and applies to the whole pre-tax bill - Little Rock is 5.2%. Also excluded: Arkansas state, city and county sales tax, the $3.31 three-phase adder, and Rider CAC, which is per-event fees rather than a recurring charge.
THE DOCUMENT URLS ARE DATED AND WILL MOVE. Arkansas is the only one of the five that files under dated WordPress upload paths, and they are inconsistent - the rate sheet under 2024/11, most riders under 2025/06, GAJA and the sample bill in the bare uploads directory. Assuming the bare path 404s on eight of the ten. When Entergy re-uploads a rider the path changes and the monitor will report it unreachable rather than changed, so an Arkansas 404 means 'go read the index page again', not 'the rider was withdrawn'.
SHORT SHELF LIFE. GGR, EECR, CCR, MISO and TA all reset with the first billing cycle of January 2027; ECR resets 1 April; GAJA holds through May 2027. Entergy's July 2026 FRP filing proposes a change to the 52.4369% figure effective 2 January 2027.
Entergy's operating companies are vertically integrated and state-regulated (New Orleans by the City Council), so a bundled residential rate exists here. That is not true of Oncor and CenterPoint elsewhere in Texas, which are wires-only and sell no energy.
