Rensselaer Cogen is an operating 88.2 MW natural-gas-fired combined-cycle electric generating facility located at 39 Riverside Avenue in Rensselaer, New York. The facility began operation in April 1994 and is owned and operated by Rensselaer Generating LLC. It consists of one combined-cycle generating unit comprising a combustion turbine, supplemental duct burners, heat-recovery steam generator, and steam turbine generator, configured to use natural gas as the primary fuel and distillate fuel oil as backup. The plant originally supplied electricity and process steam, but the steam-sales agreement with BASF Corporation expired at the end of 1999; it has since produced electricity only.

## Data quality

- The exact facility is identified by EIA plant ID 54034, NYISO PTID 23796, and historic NYISO resource ID 1713; these identifiers distinguish it from other Rensselaer-area generation projects. Historical capacity is not uniform across records: the 2006 NYISO exhibit lists 79,000 kW, EPA describes a 79 MW unit, while later plant records report approximately 88.2 MW. The EIA generator record reports 49.2 MW nameplate capacity for the combustion-turbine-part unit (with seasonal variants), which represents component-level rating distinct from the full combined-cycle plant rating. A separate transaction transferring the asset from CCI to Rensselaer Generating LLC, and its consideration, was not established in the candidate research; the operator transition is inferred from plant-history records. No documented retirement, repowering, or major expansion was identified. Recent DEC records (2022, 2025) describe permit renewal, modification, and continuation of an existing operational activity rather than a new-build or retirement project. The facility originally supplied both electricity and process steam to BASF Corporation's Rensselaer Colorants facility under a steam-sales agreement (1991–1999). After that agreement expired, the facility transitioned to electricity-only production. Energy Trading Innovations LLC is identified as the parent company of Rensselaer Generating LLC in Global Energy Monitor records, with an indicated 87% ownership stake. However, no official corporate domain or additional company documentation was identified for this parent entity. The NERC audit report confirms a single point of interconnection at 115 kV through a National Grid–owned interconnection facility. No construction contractor, EPC contractor, equipment suppliers other than the OEMs for major equipment, or other adjacent projects were identified in the candidate research.
