## Data quality

- Capacity figures use different measurement bases: Dominion lists 1,370 MW net, the Virginia SCC described the facility as 1,329 MW nominal, and FERC/EIA generator records list 1,472.2 MW of nameplate capacity across four generators. The reported $1.091 billion or approximately $1.1 billion figures describe construction or facility cost, not sale consideration or a separately identified project-finance principal. The CPV-to-Dominion purchase price was confidential. PJM continued to list Warren County CC as a 1,370 MW gas combined-cycle resource for the 2025-2026 market year. The commercial-operation date is reported as December 10, 2014 in Dominion's launch release and as December 11, 2014 in a later Dominion award release; both place operation in December 2014.
