## Data quality

- Capacity nomenclature varies by source: EIA plant records report 739.5 MW, while AMP describes the facility as nominally 700 MW with 512 MW unfired plus 163 MW of duct-firing; another project record describes the fired capacity as 675 MW. The cited project and financing materials document operation but do not disclose a retirement or repowering milestone.
