## Data quality

- The EIA record reports 619.7 MW for plant ID 56476, while the California Energy Commission and project materials describe the facility as nominally 530 MW; these figures likely represent different capacity conventions. The reported $386 million amount is identified as construction cost, not as acquisition consideration or project-financing proceeds. The CEC and project materials support January 4, 2009 as the commercial-operation date; a contemporaneous local article refers to commercial operation on January 5, 2009. CEC records show post-operation equipment and facility modifications, but the retrieved record does not identify a capacity expansion, retirement, or repowering decision through the latest 2025 compliance filing docketed in 2026.
