## Data quality

- The 588.3-MW EIA plant record is kept separate from broader Fowler Ridge complex descriptions totaling 750 MW that include Phase IV; Phase IV is not added to this plant's capacity or history. Plant-operator naming is not uniform across available records: one plant directory identifies Clearlight Energy as operator, while another plant record identifies AE Power Services LLC. Clearlight is treated as the current platform-level owner/operator following the 2025 transaction, with AE Power Services retained as an associated registered operating entity. The original construction cost and any separate construction-financing amount were not disclosed in the cited project account. The approximately $100 million disclosed by BP relates to the 2023 turbine upgrade, not sale consideration or original project financing. No retirement or decommissioning milestone is identified in the cited records; the latest plant record describes the facility as operational.
