Rate-case process
Commission-led cost-of-service regulation within a largely vertically integrated utility model.
The SCC conducts court-like rate proceedings and applies Virginia statutes to determine reasonable and prudent costs, rate base, and a fair return. Dominion's electric base rates are also reviewed through the statutory biennial-review framework.

Form EIA-861 2024 identifies this utility jurisdiction with PJM; the date records the dataset year, not the original membership start.

Full base-rate reviews set the broad revenue and return framework. Recurring riders, clauses, and reconciliations can change narrower charges between those reviews. These are governing patterns, not filing-date forecasts.

Rate adjustment clauses
Project- and rider-specific

Fuel factor
Separate periodic filing
The fuel factor passes prudently incurred fuel and purchased-power costs through a separate SCC proceeding instead of waiting for the next base-rate review.
