[1] In addition, Virginia Power has riders associated with other projects with an aggregate total revenue requirement of approximately $45 million at June 30, 2026 and pending applications associated with such riders, which if approved, would result in an annual revenue requirement increase of approximately $20 million.
[2] As approved, associated with four solar generation projects, including Bedford and Pumpkinseed (non-jurisdictional generation facilities with an aggregate recorded cost of $251 million at September 30, 2025), one energy storage project, 10 purchased power agreements and certain costs associated with expanding solar and storage facilities in addition to previously approved Rider CE projects.
[3] The total revenue requirement for Rider DIST includes $120 million for certain previously approved electric distribution grid transformation projects, $172 million for previously approved phases and proposed phase nine of certain new underground distribution facilities and $35 million for certain previously approved rural broadband capacity projects. Virginia Power recognized a charge of $24 million ($18 million after-tax) recorded primarily in impairment of assets and other charges (benefits) in the Companies’ Consolidated Statements of Income (reflected in the Corporate and Other segment) for the three and six months ended June 30, 2026, for the disallowance of certain strategic undergrounding costs previously incurred in connection with this final order. In addition, effective June 2026, the rider associated with rural broadband capacity projects was consolidated into Rider DIST and separate collection of rates under the rural broadband rider ceased.
[4] In June 2026, Virginia Power filed a petition to update and reinstate Rider RGGI to recover RGGI compliance costs incurred beginning July 2026 and those projected to occur through February 2028, with rate recovery from March 2027 through February 2028. In its petition, Virginia Power proposed an alternative mitigation approach which, if approved, would spread the recovery of costs over a two-year period and result in a total revenue requirement of $940 million for the rate year beginning March 2027.
[5] Consists of $540 million for the transmission component of Virginia Power’s base rates and $999 million for Rider T1.
