For months, the merger proposal has been under review by the Virginia State Corporation Commission (SCC), the state’s independent utility regulator, but the governor’s formal statement last week marked a notable shift in the political landscape surrounding the deal. In his public remarks, Youngkin outlined three core areas of concern: first, independent fiscal analyses showing the merger could lead to average annual household electricity rate increases of $120 to $180 over the next 15 years, adding to the 22% cumulative rate hike Virginia customers have already seen from Dominion since 2019. Second, the merged entity would control nearly 85% of Virginia’s electricity distribution market, effectively eliminating existing competition from small-scale renewable energy providers and third-party energy efficiency programs. Third, the deal could delay implementation of Virginia’s 2020 Clean Economy Act, which mandates 100% carbon-free electricity for the state by 2045, as Dominion has stated it will allocate 30% of post-merger capital expenditures to natural gas infrastructure expansion. In response to the governor’s input, the SCC announced this week that it will extend its public comment period by 30 days and add 7 additional days of public evidentiary hearings, where consumer advocacy groups, environmental organizations, energy policy experts, and Dominion representatives will be invited to testify under oath. Consumer advocacy group Virginia Citizens Consumer Council has already submitted more than 127,000 public comments opposing the merger, while Dominion officials maintain that the deal will generate $3.2 billion in operational synergies over the first decade, 80% of which will be passed directly to customers in the form of rate credits and grid upgrade investments that reduce long-term energy costs. The SCC is scheduled to issue its final ruling on the merger by the end of the third quarter of 2024, and state legislative leaders have already signaled they may introduce special legislation to block the deal if the SCC approves it without implementing strict rate caps and binding clean energy investment mandates.
