Transcription notes recorded when this tariff was encoded, including anything deliberately left out.
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.
The standard residential rate - the one a household gets by default. Tiered at 800 kWh, with the FIRST tier identical in both seasons and only the excess tier seasonal. That is the filing, not a transcription slip.
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.
