## Data quality

- The facility is currently mothballed as of the 2025 NYISO existing-generating-facilities listing (status dated December 7, 2025), transitioning from the operating status identified in regulatory and market filings through 2023–2024. This status change should be reflected in any publication. The regulatory record describes the facility as a 128-megawatt energy center, while the supplied plant anchor and EIA-derived generator nameplate capacities (92 MW + 55 MW) total 147 MW. These figures represent different capacity definitions and should not be treated as interchangeable without a capacity-definition reconciliation. The facility transitioned from cogeneration with steam customers (International Paper, then distilled-water plant) to merchant combined-cycle operation. The 2016 FERC docket ER16-925-001 and the 2016 New York PSC lightened-regulation petition address interconnection-agreement acceptance and regulatory status, not an ownership transaction or asset sale. Annual generation data (422.3 GWh) is current as of December 2024 in the EIA-derived plant record, but the facility's current mothballed status may affect future generation reporting.
