## Data quality

- The current EIA-derived record reports 795.6 MW and four operating units, while 2017 transaction materials reported approximately 640 MW or 770 MW for Troy; these figures reflect different reporting dates or capacity definitions. The disclosed $480 million amount was portfolio sale consideration, not project financing. The 2019 approximately 500 MW expansion was reported canceled. The March 2025 Troy conversion was described as a proposal, and no completed expansion, repowering, or retirement milestone was identified. A construction start date and EPC contractor were not disclosed in the gathered sources; commissioning and equipment-supplier information were available.
