Utility & rates1
- GS-5 rate class for customers demanding 25 MW or more[9]ConfirmedBacked by a filing, deed, permit, interconnection-queue record, or a government or utility record. As of Nov 25, 2025.Nov 25, 2025Dominion Energy · Virginia State Corporation Commission · Docket PUR-2025-00058 · Final order issued · effective Jan 1, 2027
“the new GS-5 rate class will comprise customers demanding 25 megawatts or more. The new rate class will be effective beginning January 1, 2027.”
Applies to Dominion Energy Virginia's service territory; the facility's utility is the most likely retail provider by location unless a source names it.

Utility, ISO and nearby assets are derived from the site's location. Proximity to a substation or line doesn't establish the interconnection; that needs a utility filing or interconnection-queue record. Queue requests are applications, not commitments — most never reach operation.
