The Virginia State Corporation Commission has issued a Final Order approving Dominion Energy Virginia’s Rider T1 transmission revenue requirement and related allocation methodology, while also ordering a new docket for proposed line-extension policy changes.

• Approved a $1,538,974,037 Rider T1 revenue requirement for the September 1, 2026 to August 31, 2027 rate year, including $998,533,997 through Rider T1 and $540,440,040 through base rates.
