Indeck Olean Energy Center is a 1×1 combined-cycle natural-gas cogeneration plant in Olean, New York, operated by Indeck-Olean Limited Partnership. The facility comprises a GE Frame 6 combustion gas turbine rated at approximately 39.6 MW, a heat-recovery steam generator with duct burner, and a Dresser-Rand steam turbine generator rated at approximately 40 MW. The plant was constructed in 1992–93 and commenced production in 1993, with a rated net generating capacity of 79.9 MW. It was originally designed to provide process steam to the adjacent Dresser-Rand Company, though it currently has no steam host and sells electric power to the grid on a contract basis. Natural gas is the primary fuel; distillate fuel oil serves as backup. The facility is connected to the National Grid transmission system at 115 kV and is interconnected at the Homer Hill substation. As of May 2025, the unit was reclassified as a Behind-the-Meter Net Generation Resource and is no longer subject to NYISO dispatch.

## Data quality

- The strongest project-specific sources are the New York State air permit (NYSDEC) and EPA regulatory record; they support the construction period, 1993 production start, configuration, fuels, owner/operator identity, and operational history. Capacity figures vary by definition: 90.6 MW nameplate (NYISO Gold Book), 79.9 MW rated net (NYSDEC permit), and 95 MW maximum (FERC LGIA). All are valid for different regulatory or operational purposes; the 90.6 MW nameplate rating has been selected as the primary technical capacity. The NRG Energy 2001 portfolio acquisition named five projects (Rockford I and II, Bourbonnais I and II, and Ilion) but did not include Indeck Olean, which remained under Indeck-Olean Limited Partnership ownership. The facility's historic role as a steam host to Dresser-Rand is documented in the permit and confirmed as no longer active.
