## Data quality

- Published sources report both a 525 MW nameplate/resource rating and a 585 MW plant capacity; these figures are retained as source-specific values rather than treated as interchangeable. The $138 million figure announced by NRG was the aggregate consideration for the Seward and Shelby County plants; GenOn’s later filing reports $75 million in cash consideration specifically for Seward. The 2004 project replaced or repowered an older plant at the site. No separate later expansion, repowering, or retirement date is identified; Seward remained listed as an operating PJM resource for 2025–2026.
