## Data quality

- The 83 MW battery facility was included in the original ORES-permitted scope (June 25, 2021); the evidence does not establish a later expansion. The December 2022 ownership event was an intra-EDF membership-interest assignment, not an identified sale to an unrelated buyer. The transfer to NYSEG concerned interconnection facilities and underlying property, not the solar generating asset; the transfer was to occur at no cost. The reviewed evidence documents construction and operation but does not document retirement or repowering. Equipment evidence identifies specific PV module, inverter, and transformer models used in the facility; official design drawings and OEM product datasheets support these identifications. The project is reported as the first to receive permitting through ORES and the largest operational solar project in New York State at its commercial operation announcement. A NYISO modification record dated March 1, 2024 mentions a reduction in feeders, which is a project configuration change, not a replacement or repowering.
