HEARING RECORD: THE CATALYST
The Virginia State Corporation Commission convened a hearing on July 14, 2026, continuing into July 15, to adjudicate Dominion Energy's proposed modification to Rider T-1, a transmission cost recovery mechanism through which the utility seeks to recoup approximately $1.5 billion in transmission infrastructure investments. The hearing represents the most significant regulatory test to date of how the Commonwealth allocates the escalating costs of grid expansion driven by hyperscale data center development in Northern Virginia.
Dominion originally projected that the average residential ratepayer would see a monthly bill increase of $2.90 under the proposed Rider T-1 adjustment. The utility subsequently revised that estimate downward to $0.94 per month based on updated load forecasting.
At the center of the dispute is the methodology for assigning costs across customer classes. Dominion's current allocation relies on a 12 coincident peak (12CP) demand methodology, which spreads transmission costs based on each class's contribution to the system's twelve highest monthly peak demands. Governor Abigail Spanberger's office, represented by Deputy Energy Officer Louise White, argued that this approach produces a "glaring cross-class subsidization" benefiting the newly created GS-5 rate class — the category encompassing large-load data center customers such as Meta, Google, Amazon, and Microsoft. White urged the Commission to adopt three specific remedies: a "but for" cost causation standard that would assign costs to the customers whose interconnection requests necessitate specific upgrades; a requirement that transmission-level Contributions in Aid of Construction (CIAC) payments be mandated for such upgrades; and a transition to a Summer/Winter Peak Average (SWPA) cost allocation methodology, which Dominion already employs in its North Carolina jurisdiction.
Jonathan Zader, Senior Assistant County Attorney for Loudoun County, testified that "the stakes are particularly high" for the county, formally requesting that cost recovery under Rider T-1 include direct allocation and CIAC payments for upgrades that are "but for" caused by interconnecting large-load customers. The Commission must issue its final order by August 1, 2026.
HEARING RECORD: STAKEHOLDER POSITIONS
Governor Spanberger's Office (Deputy Energy Officer Louise White): Advocated a "but for" cost causation standard directly assigning transmission upgrade costs to the specific interconnection requests necessitating them; mandatory transmission-level CIAC payments ensuring developers bear upfront financial responsibility; and adoption of the SWPA methodology, which averages summer and winter peak demands to produce a more equitable cross-class allocation. White framed these measures as necessary to prevent "glaring subsidization" of GS-5 customers by residential and small commercial ratepayers.
Google (Will Cleveland, attorney and lobbyist): Argued that the regulatory changes implemented in the 2025 rate case — particularly the creation of the GS-5 class and the shift to 12CP — should be allowed time to demonstrate their effectiveness. Cleveland testified that Dominion "only recently completed its shift to a 12 coincident peak demands allocation factor, and its new GS-5 rate class for large loads hasn't yet gone into full effect," characterizing the current moment as "simply too early in the process" to evaluate whether these changes alone might fairly reallocate the cost burden. He urged the Commission to direct Dominion to revise its line extension policy to permit voluntary CIAC payments, which he described as a "win-win" providing developers certainty while reducing ratepayer exposure.
Amazon (Cameron Brooks, witness testimony filed June 11, 2026): Advocated for voluntary CIAC payments as "a way to reduce ratepayer burden," arguing this approach would make "the customer's financial responsibility for the identified facilities … clear, enforceable, and integral to mitigating subsidization and stranded cost risks."
Loudoun County (Jonathan Zader): Demanded that Rider T-1 cost recovery include both direct allocation and mandatory CIAC payments for upgrades "but for" caused by large-load interconnections.
Appalachian Voices (Michael Goggin, Grid Strategies): Emphasized stranded asset risk enabled by what Brooks termed the "socialization of speculative investment" from data center developers. Goggin supported CIAC payments and direct assignment but argued these address only part of the problem: "Dominion is still far too reliant on supplemental projects and needs to be directed to utilize the PJM regional competitive transmission planning process for the bulk of its transmission investment, so that we can reduce costs for all ratepayers."
Virginia Attorney General's Office of Consumer Counsel (John Farmer, Section Chief): Expressed conceptual support for direct assignment when a cost causer is identifiable but flagged "uncertainties" warranting additional analysis, particularly regarding assignment to specific customers versus the entire GS-5 class. Farmer endorsed SWPA or an average-and-excess methodology alongside 12CP as "reasonable alternatives," stating the Consumer Council found Dominion's counterarguments to SWPA unpersuasive.
Dominion Energy (Robert Miller, Regulatory Analyst): Defended the 12CP methodology as "more appropriate" for Virginia, citing the company's smaller North Carolina service territory and absence of new high-load-factor customers there as reasons SWPA works in that jurisdiction but not in Virginia. Miller conceded, however, that SWPA "is in the zone of reasonableness," a significant acknowledgment given the utility's typical resistance to methodological changes that could reduce revenue recovery from high-growth customer segments.
HEARING RECORD: MECHANICS & EVIDENCE
The technical architecture of the dispute centers on three distinct cost allocation methodologies. The 12 Coincident Peak (12CP) method, currently used by Dominion in Virginia, allocates transmission costs based on each customer class's average demand during the twelve highest system peak hours across the year. Because data centers operate at extremely high load factors — typically 90-95% — their contribution to coincident peaks is proportionally lower than their total energy consumption would suggest, resulting in a lower per-unit cost allocation under 12CP compared to residential classes with pronounced evening peaks.
The Summer/Winter Peak Average (SWPA) methodology, which Dominion employs in North Carolina, calculates class contributions using the average of summer and winter seasonal peaks, a method that tends to increase the allocation to high-load-factor customers by capturing their consistent year-round demand.
The "but for" cost causation standard advocated by Governor Spanberger's office and Loudoun County represents a departure from class-based allocation toward project-specific assignment. Under this approach, each transmission upgrade would be evaluated to determine whether it would have been necessary absent a specific large-load interconnection request. If the answer is negative — the upgrade is "but for" caused by that request — the full cost would be assigned to the requesting customer or customer class. This standard aligns with the CIAC mechanism, which requires developers to make upfront payments for facilities directly necessitated by their interconnection, thereby eliminating ratepayer exposure to stranded cost risk if the developer later departs or reduces load.
Commission staff attorney Andrew Major stated unequivocally: "Regardless of the cost allocation methodology that is chosen, there remains a glaring cross-class subsidization occurring to the benefit of new GS-5 customers." Major recommended that if the Commission departs from 12CP, it should transition "over a multi-year period in order to facilitate gradualism and cost responsibility."
A notable evidentiary gap emerged regarding the March 2026 White House ratepayer protection pledge signed by Google, Amazon, Microsoft, and Meta. Major observed that "Google, Amazon, Microsoft and Meta signed a ratepayer protection pledge at the White House in March, adding, 'Curiously, none of those companies mentioned this pledge in either pre-filed testimony or opening statements today.'" The hearing record includes pre-filed testimony from Amazon's Cameron Brooks (filed June 11), Google's Will Cleveland, Loudoun County's Jonathan Zader, Appalachian Voices' Michael Goggin, and Consumer Counsel's John Farmer, along with Dominion's rebuttal testimony from Robert Miller.
TECHNICAL APPENDIX: COST ALLOCATION METHODOLOGIES
12 Coincident Peak (12CP): Allocates transmission costs based on each customer class's average demand during the twelve highest system peak hours across the year. Tends to assign lower relative costs to high-load-factor customers (e.g., data centers operating at 90%+ load factor) because their demand is relatively constant and thus contributes less disproportionately to system peaks compared to residential classes with sharp evening peaks.
Summer/Winter Peak Average (SWPA): Calculates class contributions using the average of summer and winter seasonal peaks. Captures consistent year-round demand of high-load-factor customers, generally increasing their allocated share relative to 12CP. Currently used by Dominion in its North Carolina jurisdiction.
"But-For" Cost Causation Standard: Project-specific assignment methodology. Each transmission upgrade is evaluated to determine if it would have been necessary absent a specific large-load interconnection request. If the upgrade is "but for" caused by that request, the full cost is assigned to the requesting customer or class. Replaces or supplements class-based allocation for identifiable discrete projects.
Contributions in Aid of Construction (CIAC): Upfront payments required from developers for facilities directly necessitated by their interconnection. Eliminates ratepayer exposure to stranded cost risk if the developer later departs or reduces load. Can be mandatory (as proposed by Governor/Loudoun) or voluntary (as proposed by Google/Amazon).
GS-5 Rate Class: Created in Dominion's 2025 rate case for large-load customers exceeding 5 megawatts of demand. Explicitly identified cost shifting as the "entire premise" of the new rate design (per Google's Will Cleveland testimony). Has not yet gone into full effect as of the July 2026 hearing.
COMMISSION STAFF RECOMMENDATIONS
Commission staff attorney Andrew Major presented the following positions:
1. Acknowledged that "regardless of the cost allocation methodology that is chosen, there remains a glaring cross-class subsidization occurring to the benefit of new GS-5 customers."
2. Recommended that if the Commission departs from 12CP, it should transition "over a multi-year period in order to facilitate gradualism and cost responsibility."
3. Noted the absence of the March 2026 White House ratepayer protection pledge from hyperscaler testimony, observing: "Google, Amazon, Microsoft and Meta signed a ratepayer protection pledge at the White House in March, adding, 'Curiously, none of those companies mentioned this pledge in either pre-filed testimony or opening statements today.'"
4. Did not quantify the magnitude of allocation shift under SWPA relative to 12CP, stating only that the transition schedule and updated load profiles would determine the impact.
ANALYTICAL ASSESSMENT
Structural Tensions: The hearing record reveals a fundamental misalignment between 20th-century utility cost allocation frameworks and 21st-century load growth driven by hyperscale data centers. The core dispute is not whether cross-subsidization exists — Commission staff, Consumer Counsel, and multiple intervenors agree it does — but the pace and mechanism of its correction.
Methodological Trade-offs: The 12CP methodology systematically allocates a lower share of transmission costs to high-load-factor customers (GS-5) than their total energy consumption would imply under alternative methodologies; Dominion contests that this constitutes "under-allocation," arguing 12CP remains appropriate for Virginia's system topology. Dominion concedes SWPA is "in the zone of reasonableness" for Virginia.
White House Pledge Omission: The absence of the March 2026 White House ratepayer protection pledge from hyperscaler testimony is noted in the record. While the pledge is voluntary and non-binding in SCC proceedings, its omission may inform the Commission's assessment of the GS-5 class's voluntary commitments versus mandatory cost-causation mechanisms.
Four-Position Spectrum: The record presents a spectrum of positions, not a binary choice: (1) Status Quo / 12CP Maturation (Dominion, Google, Amazon); (2) Staff Hybrid (Multi-year SWPA transition + gradualism); (3) Direct Assignment + Mandatory CIAC + SWPA (Governor, Loudoun); (4) Hybrid Direct Assignment + Regional Competitive Planning (Appalachian Voices, Consumer Counsel). The Consumer Counsel's position — direct assignment where identifiable + SWPA/average-and-excess for shared network — occupies a middle ground likely to influence the final order.
Definitional Challenge: The practical challenge for any "but for" standard lies in defining causation for meshed network upgrades where multiple drivers coexist — a methodological question the Commission may delegate to subsequent rulemaking or technical conference.
PROCEDURAL OUTLOOK
The Commission's August 1, 2026 deadline creates a compressed timeline for a decision that will establish precedent for Virginia's utility regulatory framework and potentially influence cost allocation proceedings in other data center-intensive states.
Three primary procedural outcomes appear plausible based on the record:
1. Adoption of SWPA with Multi-Year Transition: Aligning with Commission staff recommendation. Would increase GS-5 allocation relative to 12CP; magnitude depends on transition schedule and updated load profiles. No witness, model, or staff report in the record quantifies the shift as a specific percentage range.
2. Hybrid Approach: Incorporating direct assignment for identifiable "but for" projects alongside a modified class-based allocation for shared network upgrades. Aligns with Consumer Counsel and Loudoun County positions. Requires subsequent methodological work to define "but for" causation for meshed upgrades.
3. Status Quo Maintenance: Accepting Dominion's argument that 12CP remains appropriate and that the GS-5 class provisions from the 2025 rate case should be allowed to mature. Would represent a significant victory for hyperscale operators and may prompt legislative intervention in the 2027 General Assembly session.
Market implications cited in equity research (not in hearing record) suggest Dominion Energy (NYSE: D) faces earnings sensitivity to the outcome, while hyperscale operators (META, GOOGL, AMZN, MSFT) may evaluate alternative sites if mandatory CIAC payments or higher allocated transmission costs increase effective Virginia capacity costs. PJM Interconnection's regional planning process could see increased scrutiny if the Commission directs greater reliance on competitive transmission planning for bulk system upgrades, per Appalachian Voices' recommendation.
