This document contains the combined reports (“Report") of the Virginia State Corporation Commission (“Commission") submitted pursuant to several provisions of law. The Commission has reviewed and investigated each of the areas or topics listed below, and reports as follows:

Grid Modernization, Reliability, and Integration of Renewables (The Grid Transformation and Security Act (“GTSA"), 2018 Virginia Acts of Assembly Chapter 296) and Infrastructure Investments to Improve Reliability (2022 Virginia Acts of Assembly Chapter 653):

Concerning reliability, Virginia electric utilities continue to participate in regional transmission planning through PJM Interconnection, L.L.C. (“PJM"), the entity that manages the electric grid primarily at transmission-level voltages. At the distribution level, the Commission monitors reliability in part through utility reports on measures related to tree-trimming and indices that measure frequency and duration of electricity service outages.

Utility-owned and third party-owned renewable generation resources are being added to the electric distribution grid. Before connecting utility-scale resources to the electric grid, owners must coordinate with the affected local utility and with PJM. Under certain circumstances, the projects are also subject to Commission approval.

Concerning grid security and grid hardening activities, the Commission has previously given approval for Virginia Electric and Power Company d/b/a Dominion Energy Virginia (“DEV" or "Dominion") to implement, among other things, mainfeeder hardening, targeted corridor improvement, voltage island mitigation, hosting capacity analysis, and physical and cyber security. Appalachian Power Company (“APCo") has filed its first GTSA petition which seeks to implement distribution automation circuit reconfiguration and other investments to reduce circuit exposure. APCo’s petition is currently pending before the Commission and will be addressed in greater detail in a future Report.

Both DEV and APCo are expected to have sufficient capacity to meet peak energy demands in the near term,(*1) either through company-owned generation or market purchases. Both companies also continue to invest in the generation, transmission, and distribution of electricity. During 2024, such annual investments were:

Company: Dominion Energy Virginia
Generation: $1,647.0 million
Transmission: $1,246.0 million
Distribution: $1,327.0 million

Company: Appalachian Power Company
Generation: $231.3 million
Transmission: $289.7 million
Distribution: $391.9 million

With respect to infrastructure investments to improve reliability, as part of recent GTSA filings, Dominion is performing: (i) mainfeeder hardening projects targeting improvements for poorly performing mainfeeder segments; (ii) targeted corridor upgrades that remediate ash tree mortality and apply herbicides for ground floor maintenance; (iii) substation technology deployment projects; and (iv) fault location, isolation, and service restoration projects (“FLISR").

Construction of New Solar and Wind Projects (GTSA, 2018 Virginia Acts of Assembly Chapter 296) and Storage Projects (2020 Virginia Acts of Assembly Chapter 1190):

Between July 1, 2018, and June 30, 2025, Virginia utilities placed into operation solar and wind facilities totaling 2339.70 megawatts (“MW") of nameplate generation capacity in the Commonwealth. Dominion also has under development approximately 6,656.78 MW of Company-owned and contracted nameplate solar generation and 2,587 MW of nameplate offshore wind generation capacity located off the Commonwealth's Atlantic shoreline.(*2)

APCo currently has 112.5 MW of contracted nameplate solar generation capacity under development as of June 30, 2025. Third parties are also developing facilities that may provide approximately 5,965.78 MW of additional nameplate solar generation capacity in the Commonwealth. DEV has constructed five energy storage facilities for a total of 36 MW of energy storage in operation. Other utilities, third-party generators, and electric cooperatives collectively have 2,628.64 MW of energy storage under development.

Third Party Power Purchase Agreement Pilot Program (Chapter 382 of the 2013 Virginia Acts of Assembly):

The Third Party Power Purchase Agreement (“PPA") Pilot Program is underway for each investor-owned electric utility in Virginia. This program enables the owner or operator of a solar-powered or wind-powered electricity generation facility, located on premises owned or leased by an eligible customer-generator, to sell the electricity generated from such facility exclusively to the eligible customer-generator under a PPA. The pilot programs are limited to aggregated capacity not exceeding: (i) 500 MW for Virginia jurisdictional and 500 MW for Virginia non-jurisdictional customers; and (ii) six percent of each Pilot Utility's adjusted Virginia peak-load forecast for the previous year.

As of November 1, 2025, the cumulative capacity of facilities participating in the Third Party PPA Pilot Program has not yet reached the participation caps for any utility. Notices of intent for each PPA program currently constitute an estimated 76.5 MW, 13.3 MW, and 7.6 MW of total solar generating capacity for DEV, APCo, and Kentucky Utilities Company d/b/a Old Dominion Power Company (“ODP"), respectively. It is worth noting that ODP has received notices of intent for almost 88.3% of its available capacity,(*3) the largest percentage of the three utilities.

(*1) DEV’s 2025 IRP Update build plans are inclusive of CERC. Commonwealth of Virginia, ex rel. State Corporation Commission, In re: Virginia Electric and Power Company’s 2025 Updated to the 2024 Integrated Resource Plan filing pursuant to Va. Code § 56-597 et seq. in Case No. PUR-2025-00184 at Figure 5.1.1.3.
(*2) These figures reflect data provided by Dominion as of June 30, 2025. In next year's report, the Commission will update these amounts to include additional projects and purchased power agreements (“PPAs") proposed in Dominion's 2025 RPS Filing, Case No. PUR-2025-00148, filed on October 15, 2025, and currently pending at the Commission.
(*3) As of November 1, 2025 ODP’s maximum available Third Party PPA program capacity is 8.6 MW. ODP has 7.6 MW capacity that has been assigned to projects that have either been completed or are in some phase of contracting and construction. The unassigned portion of the program that remains available for entities in 2025 is 1.0 MW of capacity. ODP’s forecasted increase in 2026 Virginia Peak load will increase the total capacity in the program from 8.6 MW to 10.2 MW. Assuming no projects submit a notice of intent prior to January 1, 2026, this would mean that the unassigned capacity available for new Third Party PPA projects would increase from 1.0 MW to 2.6 MW.
