Policy Details
What Changes
The Virginia State Corporation Commission approved a new GS-5 rate class for very large electricity customers, including hyperscale data centers. The class applies to customers with demand of 25 MW or more and introduces specific pricing and minimum-demand requirements intended to ensure that large customers contribute more directly to the cost of serving their electricity demand.
The new rate class takes effect January 1, 2027.
Who Is Affected
Large electricity customers meeting the GS-5 eligibility threshold, particularly hyperscale data centers and other high-demand commercial or industrial users, as well as Dominion Energy Virginia and electricity customers that could otherwise bear a portion of large-load infrastructure costs.
Why It Matters
The policy establishes a specific regulatory framework for recovering the cost of serving very large electricity users. It is particularly significant for Virginia's data-center market because large facilities require substantial generation, transmission and distribution capacity.
The policy could influence the economics and location of future data-center projects and provides a potential model for other states dealing with rapidly increasing electricity demand from large technology facilities.
Expected Impact
Higher direct cost responsibility for large electricity users; stronger cost recovery for grid infrastructure; potential changes to data-center project economics and site selection.
Risks / Uncertainties
The full commercial impact will not be known until the GS-5 class is implemented in January 2027. Key uncertainties include how qualifying customers respond to the new rate structure, how Dominion applies the requirements in practice, and whether other states adopt similar large-load rate frameworks.
What Happens Next
GS-5 implementation begins January 1, 2027. Monitor Dominion Energy Virginia's implementation and the treatment of qualifying large-load customers.
Commercial Opportunity
Potential demand for power generation, transmission, distribution, substations, grid equipment, engineering and construction services as Virginia accommodates large electricity users.

Analyst Notes
Regulatory Context:
The GS-5 rate class was established by the Virginia State Corporation Commission as part of Dominion Energy Virginia's 2025 biennial review. The framework is intended to address the cost and operational implications of serving very large electricity customers, particularly hyperscale data centers and other large-load facilities.
Eligibility:
The GS-5 class applies to customers meeting the Commission's large-load eligibility requirements. The principal threshold is 25 MW or greater demand. It is not exclusively a data-center tariff; other customers meeting the applicable requirements can also fall within the class.
Cost Recovery:
The policy is designed to improve recovery of the costs associated with serving large electricity users and reduce the possibility that infrastructure and service costs attributable to large loads are shifted to other customer classes.
Implementation:
The Commission's decision was issued on November 25, 2025, with the new GS-5 rate class scheduled to take effect on January 1, 2027.
Strategic Significance:
Virginia is one of the most important U.S. data-center markets. The GS-5 framework therefore provides an important regulatory precedent for how jurisdictions can respond to rapidly increasing electricity demand from hyperscale facilities.
Monitoring Points:
Project Herald should monitor the practical implementation of GS-5, the number and type of customers entering the class, the resulting electricity-cost implications for large-load projects, and whether other U.S. jurisdictions introduce comparable large-load rate structures.
Relationship to FERC Large-Load Policy:
The GS-5 framework should be tracked alongside FERC's June 2026 large-load interconnection proceedings. The two developments address different regulatory layers: Virginia's framework concerns the recovery and allocation of electricity-service costs, while FERC's action addresses interstate transmission tariffs and the connection of large electricity users to the grid.
Important Classification Note:
GS-5 should be treated as a large-load electricity rate framework, rather than labelled as a data-center-only policy. Data centers are a major affected group, but the policy is broader than the data-center sector.
