Batavia Power Plant is a natural-gas-fired combined-cycle cogeneration facility located at 163 Cedar Street in Batavia, Genesee County, New York. It is configured as a 1+1 combined-cycle cogeneration block with a GE Frame 6 (FR6001) gas turbine, a GE Fitchburg steam turbine, and a Zurn heat-recovery steam generator. The facility was originally constructed to provide both heat and electricity to the adjacent O-AT-KA dairy facility. It is currently operated by Seneca Power Partners, L.P. and participates in the NYISO wholesale energy market as a peaking unit, selling capacity, energy, and ancillary services when called upon during periods of high electrical demand. The plant is interconnected to the electrical grid under a FERC-approved large-generator interconnection agreement and is listed in the NYISO Gold Book. As of December 7, 2025, the NYISO market resource Batavia B (PTID 24024) is identified as retired under the Market Services Tariff.

## Data quality

- The exact facility is identified across federal (EIA/FERC), state (NYSDEC/DEC), and ISO (NYISO) regulatory records as Batavia Power Plant, EIA plant ID 54593, located at 163 Cedar Street, Batavia, Genesee County, New York. Capacity discrepancy: DEC records state 67.3 MW; the Alliance project page states 62 MW. The regulatory 67.3 MW figure is supported by FERC EIA unit-level data (GEN1 47.7 MW + GEN2 18.5 MW + GEN3 1.1 MW = 67.3 MW). The registry anchor value of 66.2 MW does not match either source. The 2005 ownership history is described differently by two sources: DEC says Seneca acquired Batavia station; Alliance page says Alliance acquired the plant. Both sources confirm the 2005 date and exact facility identity. The evidence supports a 2005 transfer into the Alliance/Seneca ownership structure but does not identify the prior seller. Current operator is Seneca Power Partners LP per NYSDEC title V permit application, FERC generator records, and NYISO market records. The plant's market resource, Batavia B (PTID 24024), is identified by NYISO as retired under its Market Services Tariff as of December 7, 2025. No Batavia-specific allocation was identified. No documented expansion, repowering, or retirement event prior to the 2025 retirement status was identified for the exact Batavia Power Plant.
