[1] | During 2023, Virginia Power determined the Bookers Mill solar project under development will be utilized to support its utility customers and included the project in its most recent Rider CE application. See Note 13 for additional information.
[2] | Includes $2.9 billion associated with the CVOW Commercial Project. Virginia Power’s February 2024 construction progress filing with the Virginia Commission included an estimated total project cost of $9.8 billion, excluding financing costs. In accordance with the Virginia Commission’s order in December 2022, the Companies are subject to a cost sharing mechanism in which Virginia Power will be eligible to recover 50% of such incremental costs which fall between $10.3 billion and $11.3 billion with no recovery of such incremental costs which fall between $11.3 billion and $13.7 billion. There is no cost sharing mechanism for any total construction costs in excess of $13.7 billion, the recovery of which would be determined in a future Virginia Commission proceeding.
