## Data quality

- Capacity figures reflect different scopes and reporting dates: the EIA-derived plant record reports 1,825 MW, Olympus reported 1,612 MW, Bracewell described the acquired facility as 1,613 MW, and the FERC market-power filing focused on the 1,200 MW steam Units 3 and 4. The December 2023 Olympus transaction and November 2024 Rockland transaction were separate ownership events. No project-financing debt amount or Chalk Point-specific sale consideration is identified in the cited transaction materials. The clearly documented generation change is the retirement of coal Units 1 and 2 while the natural-gas and oil-fired capacity continued operating.
