(2) | In January 2022, Virginia Power filed a motion to withdraw its application as a result of the announcement by the Governor of Virginia that he intends to withdraw Virginia from RGGI. The Virginia Commission granted Virginia Power’s motion in April 2022. See additional discussion below.
(3) | Virginia Power also requested approval of cost recovery of approximately $1.2 billion through Rider SNA for the first phase of nuclear life extension program which includes investments through 2024. In April 2022, Virginia Power, the Virginia Commission staff and certain interested parties filed a proposed stipulation recommending that costs incurred after February 2022 associated with the first phase of the nuclear life extension program for North Anna be deferred and requested for recovery in a subsequent Rider SNA filing.

(5) | Consists of $60 million for previously approved phases and $35 million for phase six costs for Rider U.
In May 2022, Virginia Power filed a petition with the Virginia Commission requesting a suspension of Rider RGGI approved in August 2021. Virginia Power also requested that RGGI compliance costs incurred and unrecovered through July 2022 be recovered through existing base rates in effect during the period incurred. If approved by the Virginia Commission, Virginia Power expects to record charges to its Consolidated Statement of Income for the amount of any unrecovered costs, which are estimated to be approximately $215 million, including the impact of certain non-jurisdictional customers which follow Virginia Power’s jurisdictional customer rate methodology. This matter is pending.
