This plan prices by time of day, so a monthly total alone does not determine the bill. The columns are the bounds: every kWh in the cheapest period, and every kWh in the dearest. A real bill falls between them, and where it falls is what this plan is asking you to change.
Before taxes, franchise fees and any local surcharge.

Encoded from the same tariff book, on the same day. Which one
you are on is on your bill; which one you are eligible for is set by the
utility, not by this page.
Transcription notes recorded when this tariff was encoded, including anything deliberately left out.
TWO COMPONENTS ARE INSIDE THE ENERGY CHARGE, NOT ADDED TO IT, and the schedule is explicit about which way round it is: 'The energy charges above INCLUDE a Storm Damage component of $0.00032 per kWh' and 'The above charges REFLECT the Capital Cost Component Rider adjustment'. Adding either would double-count it. Recorded because Duke Energy Carolinas shipped understated by missing a storm charge whose schedule used the opposite wording - 'will be added to the monthly bill' - and the two cases are indistinguishable without reading the sentence.
Dominion Energy South Carolina, Inc. (formerly SCE&G) is a SEPARATE operating company from Virginia Electric and Power Company, which trades as Dominion Energy Virginia and Dominion Energy North Carolina. Same brand, different filings, different regulator, different rates.
The basic facilities charge is filed PER DAY, not per month. It is encoded per day, so February and July differ by three days' worth.
Summer is May-September and winter is October-April. Dominion Energy Virginia's summer is June-September. The seasonal boundary does not carry between the two companies.
NO TAX RIDER. Dominion's SC bill-explanation page still refers to a Tax Rider credit, and 2020-era schedules carry a 3.07% reduction under PSC Orders 2020-331/332/333. Every schedule filed under Order No. 2026-374 contains zero occurrences of 'Tax Rider'. The website text is stale. Applying the 3.07% would make this rate low by that amount.
The energy charge already INCLUDES fuel $0.03949, DSM $0.00278, pension $0.00024 and storm damage $0.00032 per kWh, and reflects the Capital Cost Component Rider adjustment. These are not added - adding them would double-count $0.04283 per kWh.
$1.00 per account per month is added for the Distributed Energy Resource Program. It is encoded as the monthly fixed charge, alongside the per-day facilities charge.
The filed minimum charge is 'the basic facilities charge and the Distributed Energy Resource Program charge' - exactly the fixed component encoded here. It can therefore never bind, and minmonthlycharge is left unset rather than being given a scalar that would misstate short months.
PLAUSIBILITY CHECK ONLY, not verification: coverage of the May 2026 settlement (7.6%, down from a 12.73% ask) says a 1,000 kWh residential bill goes from about $157 to about $169. Rate 8 here gives $169.38-$169.74 in winter and $173.76-$174.12 in summer, depending on month length. The press figure states no season, no month length and no tax basis, so it is recorded as context and asserted on by nothing - the Dominion Virginia encoding was nearly discarded over exactly such a number, which turned out to be the stale one.
NOT RECONCILED against a published total. South Carolina publishes no bill calculator and no sample-bill arithmetic; the Virginia workbook is a Virginia artefact, not a Dominion one. Correctness here rests on transcription from the filed sheets, cross-checked only where Rate 1 and Rate 6 file identical figures.
EXCLUDED: South Carolina sales tax, franchise fees and business license taxes, which the schedules add on top and which vary by locality.
Available on a voluntary basis - an opt-in alternative to Rate 8, so /compare can rank it honestly.
The three energy rates do NOT vary by season. Only the hours move: summer on-peak is 4pm-8pm, winter on-peak is 6am-9am. The schedule is filed under separate summer and winter headings carrying identical prices, which looks like a transcription slip and is not.
Super off-peak is 1am-5am year round, plus noon-3pm in the October-April winter only. Off-peak is every hour not named on-peak or super off-peak.
The filed sheet names no weekday, weekend or holiday exception, so the on-peak windows are encoded for all seven days. Most time-of-use schedules in this catalogue exempt weekends; this one does not say so.
A customer who leaves this schedule may not take any residential time-of-use rate for twelve months. That is a switching cost /compare does not model.
Levelized payment plans are not available on this schedule.
The basic facilities charge is $0.42740 per day here against $0.36164 on Rate 8 - about $2.00 more a month before any kWh.
SKIPPED Rate 1 (Good Cents): 'Effective January 15, 1996 this schedule is closed and not available to any new structure.' Nobody can switch to it, so it is useless for /compare.
SKIPPED Rate 2 (Low Use Residential): available only where consumption has not exceeded 400 kWh in each of the twelve preceding billing months. Eligibility depends on billing history the caller does not supply, and the encoding cannot express it, so /compare would recommend it to people who cannot have it.
SKIPPED Rate 6 (Energy Saver / Conservation): open, but conditional on R-38 ceilings, SEER2 16 cooling, sealed and R-8 ducts, insulated glazing and a builder verification form, with an on-site audit at the Company's option. It undercuts Rate 8 on every tier in both seasons at an identical facilities charge, so encoding it would put it top of every South Carolina /compare result while most households cannot qualify. Blocked on eligibility modelling, not on data.
SKIPPED Rate 7 (TOU-Demand): carries a demand charge of $10.90 per kW of on-peak billing demand in both seasons. rategrid does not model demand charges. It also bills on MAXIMUM INTEGRATED FIFTEEN MINUTE demand, and every entry point to this engine takes 8760 hourly values - an hourly average cannot recover a 15-minute peak and would understate it. Blocked on both demand-charge support and sub-hourly load data.
