## Data quality

- The historical solar project was reported at 200 MWac/272 MWp, while the current EIA plant record reports 273.1 MW nameplate across solar and storage; these figures describe different configurations and should not be treated as interchangeable. The approximately $480 million figure refers to project debt and related facilities, not sale consideration. The approximately $307 million PKA transaction covered Garland and the separate Tranquillity facility together, not Garland alone. The plant remains listed as operational with three operational units and no planned units; no separate retirement or repowering milestone is identified in the cited history.
