Rate Schedules & Tariff Analysis
DESC C&I bills are dominated by two components: a per-kW billing demand charge and per-kWh energy charges, plus fuel and regulatory riders (including DSM). Demand charges typically set the largest portion of a large customer's bill, so load-factor and peak management drive cost outcomes. Time-of-use schedules (Rate 24) reward shifting consumption off-peak. Exact rate values are set by the SC PSC and should be read from the current tariff book.
Dominion Energy South Carolina Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate 9 - General Service | Small/medium commercial. |
| Rate 24 - Large General Service (TOU) | Large commercial, time-of-use. |
| Rate 23 - Industrial Power Service | Industrial with demand/classification thresholds. |

Dominion Energy South Carolina Data Access FAQ
How can a business get 15-minute interval data from DESC?▾
Commercial and industrial customers with interval meters use MV-WEB at https://mvweb.dominionenergyse.com/. Request access through Large Business Services at 866-913-9762. MV-WEB supports 15-minute, hourly, daily, weekly and monthly load profiles with CSV export and scheduled reports.
Does DESC support Green Button or a public API?▾
No. DESC does not offer Green Button Download My Data, Connect My Data, or a public developer API. Interval data is exported as CSV from the Detailed Energy Usage portal (residential) or MV-WEB (C&I), and automated billing uses EDI.
How does a consultant or aggregator access a customer's DESC data?▾
The customer completes the DESC Third-Party Letter of Authorization specifying data types and duration, submits it to EDISCegbilling@DominionEnergy.com, and DESC issues MV-WEB credentials for the authorized account(s). For ongoing billing automation, EDI enrollment is the primary route.
What C&I rate schedules does DESC offer?▾
DESC's main non-residential electric schedules include Rate 9 (General Service / small commercial), Rate 24 (Large General Service, time-of-use) and Rate 23 (Industrial Power Service), plus Large Power Service options. Larger schedules are demand-metered (billed on kW demand plus kWh energy). Exact rates are set by the SC PSC; see the tariff book for current figures.
How do DESC business rates change?▾
Rates are set by the South Carolina Public Service Commission through base-rate cases and fuel-cost proceedings. In January 2026 DESC filed a rate review; a May 2026 settlement set an overall increase near 7.6% (lower than the ~12.7% initially requested), with new rates expected mid-2026 pending PSC approval. Always confirm current rates in the DESC tariff book.
