Virginia utility regulators hear challenge over how data-center transmission costs are allocated

Virginia utility regulators held a hearing Tuesday on how the costs of certain electric transmission projects should be allocated when the work is driven by growth in data centers and other large load customers, according to reporting from UtilityDive and an energy-focused news roundup. The proceeding was before the Virginia State Corporation Commission, where Dominion Energy advanced a cost-allocation approach tied to transmission projects that the company says are needed to serve incremental demand.

The hearing drew participation from Virginia Gov. Abigail Spanberger’s office, and from several large technology and cloud companies, including Meta, Google, Amazon and Microsoft, according to the report. Those organizations weighed in on how Dominion’s transmission-cost allocation would affect customers and rates, and they sought to clarify the standards and accounting used to determine who pays for grid upgrades associated with data center development.

The reporting characterizes the issue as a dispute over whether the proposed framework would result in what critics call “subsidization” of grid investments by existing customers, particularly if the costs of transmission expansions are not fully tied to the incremental economic value or payment obligations of the new large-load developers. Dominion’s proposal, as described in the coverage, focuses on allocating transmission project costs in a way that reflects the drivers of the grid upgrades.

The article also notes that Louise White was the author of the referenced coverage, and it frames the hearing as part of a broader question regulators face when the electricity system must expand to meet demand concentrated in a subset of customers. Transmission projects can involve long planning timelines, substantial capital expenditures, and multi-year cost recovery mechanisms, making the allocation methodology a key determinant of who bears near-term rate impacts while the projects are built.

While the coverage summarizes the positions presented at the hearing, it does not provide docket numbers, specific tariff language, or regulator vote details. The practical effect of the commission’s eventual decision will depend on how the VPSC applies Dominion’s proposal, including what costs are included, how “data center-driven” projects are identified, and the extent to which existing ratepayers vs. new load customers are assigned responsibility.

Next steps in the proceeding would be determined by the VPSC’s process after the evidentiary hearing, including any further filings, review of the record, and a commission order that sets the final cost-allocation approach for future transmission investment tied to load growth in the state.
