## Data quality

- The $2.8 billion Dynegy transaction completed in 2015 covered Duke Energy’s non-regulated Midwest commercial-generation business; Duke Energy Ohio and Kentucky regulated utilities were excluded, so that portfolio value is not a Woodsdale sale price. Duke Energy’s 2026 Woodsdale page concerns substation and transmission-line work rather than additional generating units; it is not counted as a generation expansion of EIA plant 7158. The proposed Woodsdale Solar Center is treated as a separate solar project and is not merged into the natural-gas Woodsdale generating plant.
