The Virginia State Corporation Commission has approved a new rate rider for Dominion Energy Virginia to recover a portion of costs spent to meet state and federal environmental regulations. Known as Rider E, the rate adjustment clause will take effect on or before November 1, 2019. Since 2007, Virginia’s two largest electric companies generally recover the cost of providing service, plus a reasonable return, through three bill components: base rates, a fuel charge, and rate adjustment clauses also known as rate riders. The approval of Rider E means there are now 15 riders, including the fuel rate, paid by residential customers of Dominion Energy Virginia. Initially, Rider E will pay for certain environmental projects, including cleaner disposal of coal ash, at several coal-fired power plants. The new charge will be calculated based on a total revenue requirement of $107,354,000, and a rate of return on common equity of 9.2%.  Re Virginia Electric & Power Co., Case No. PUR-2018-00195, Aug. 5, 2019 (Va.S.C.C.).
