• October 23, 2026, Virginia State Corporation Commission: Dominion's large-load connection queue case continued after FERC ruling on PJM. In Case No. PUR-2026-00011, Dominion's application of February 2, 2026 for approval of its large-load connection queue process standards, the Commission takes judicial notice of FERC's October 9, 2026 order in Docket ER26-3515. That FERC order rejected PJM's proposed Interim Resource Adequacy Service and found that parts of PJM's large load proposal appear to intrude on retail rate regulation. The order recites that hearings began April 28, 2026 and that an interim order establishing an additional proceeding was entered May 25, 2026. It does not approve or reject Dominion's standards; it states that the matter is continued. Virginia SCC Order, Case No. PUR-2026-00011
• October 15, 2026, Dominion Energy Virginia (filed with the Virginia SCC): Dominion files its 2026 resource plan update. Dominion's 2026 Integrated Resource Plan update, filed in Case No. PUR-2026-00163, presents 17 modeling scenarios for meeting customer demand over 20 years. The company states that the IRP is not a request to approve a specific project, resource portfolio, or cost recovery. It says demand forecasts for the Dominion Zone of PJM continue to increase. Its near-term plan includes a new gas-fired resource expected to enter service by June 2029 and a solicitation for up to 7.3 GW of dispatchable generation with potential in-service dates through 2036. It notes that PJM's 2028/2029 capacity auction left committed capacity more than 6,800 MW below PJM's reliability requirement.

• July 31, 2026, Virginia State Corporation Commission: Transmission rider set; Dominion told to charge large loads up front for direct-connect facilities. The final order on Rider T1 approves the uncontested transmission revenue requirement of $1,538,974,037 for the rate year September 1, 2026 through August 31, 2027. The Commission states that it is without discretion to add to or subtract from these costs. It approves an amended allocation method that applies the new 85% minimum transmission charge for large-load customers beginning January 1, 2027. It says this reduces the projected Rider T1 monthly increase for a typical 1,000 kWh residential customer from $2.90 to $0.94. It directs Dominion to file, within 90 days and in a new docket, an amended line extension policy requiring a mandatory contribution in aid of construction for direct connect transmission facilities, generally substations and the lines connecting a new or expanding large-load customer to the bulk system. It takes a more deliberate approach to assigning higher-order transmission costs and says the new docket may consider that question. Virginia SCC Final Order, Case No. PUR-2026-00056
• March 31, 2026, Court of Appeals of Virginia: Prince William Digital Gateway rezonings held void. The Court of Appeals held that the Board of County Supervisors' advertising for its December 2023 public hearing violated Code 15.2-2204(A) and county Zoning Ordinance 32-700.60. It held that this renders the three data center rezonings known as Compass, Digital Gateway North and Digital Gateway South void ab initio. It affirmed the circuit court judgment that invalidated all three and held that at least one of the Oak Valley plaintiffs has standing to challenge them. It also held that the circuit court erred in dismissing the same claim in a companion case, Burke, but did not send that case back because this ruling makes further relief there unnecessary. Court of Appeals of Virginia, Board of County Supervisors of Prince William County v. Oak Valley Homeowners Association, Record Nos. 1590-25-4, 1584-25-4, 1592-25-4, 2025-24-4 (published opinion)
• November 25, 2025, Virginia State Corporation Commission: Dominion base rates set; new GS-5 class for customers of 25 MW or more. The final order in Dominion's 2025 biennial review finds annual base rate revenue increases of $565.7 million for 2026 and $209.9 million for 2027. It says these mean approximate monthly increases for a typical 1,000 kWh residential customer of $11.24 in 2026 and an additional $2.36 in 2027. It creates Rate Schedule GS-5, effective January 1, 2027, for customers with a measured or contracted demand of 25 MW or more on a contiguous site and a load factor of at least 75%. For customers signing an electric service agreement on or after that date, the order sets a 14-year contract term, minimum charges of 85% of contracted demand for distribution and transmission and 60% for generation, collateral of $1.5 million per MW, and an exit fee covering outstanding minimum charges. The Commission did not address comprehensive transmission planning or transmission cost allocation in this case. It directed Dominion to propose alternative transmission cost allocations in its next transmission rider filing and to file its large-load interconnection queue process in a separate case by February 2, 2026. Virginia SCC Final Order, Case No. PUR-2025-00058

What this page cannot tell you about a bill

Dominion's Virginia electric rates are set by the State Corporation Commission in rate cases. Base rates let the utility recover its reasonable and prudent operating costs plus a fair return on its rate base, which is its investment in things like generating stations and the distribution grid. Fuel costs can be recovered annually if they are proven reasonable. Transmission costs, and other costs such as environmental compliance and generation facilities, are recovered through separate rate surcharges, and the transmission surcharges may change annually (Virginia State Corporation Commission, Electric Rates in Virginia: How are they determined by the State Corporation Commission?). A statewide residential average blends every utility's residential customers, and nothing on this page shows how much any project or power line added to a household's bill. EIA publishes the averages by state: Electric Power Monthly, Table 5.6.A.
