Brooklyn Navy Yard Cogeneration is an operating natural-gas-fired combined-cycle cogeneration facility located at 63 Flushing Avenue, Building 41, in the Brooklyn Navy Yard in Kings County, New York. The facility comprises two Siemens V84.2 gas turbines, each equipped with a heat-recovery steam generator, two Siemens SST-800 steam turbines, Siemens SGen6-1000A generators, SPPA-T3000 controls, and two distillate-oil emergency generators. The facility produces 286 MW of electricity and supplies steam to Consolidated Edison, the Brooklyn Navy Yard, and the Red Hook Water Pollution Control Plant. Approximately 98% of generation is sold to Con Edison under a long-term power purchase agreement. The facility operates in NYISO Zone J and is owned by Brooklyn Navy Yard Cogeneration Partners, L.P., with current ownership divided between Axium BNY LLC (58.4%) and Mission Energy New York, Inc. (41.6%).

## Data quality

- The exact facility is identified by EIA plant ID 54914, regulatory permits, official project website, and multiple transaction records. Asset identity is resolved. Capacity is reported inconsistently across sources: 286 MW is the facility's stated output power (regulatory permits, official website); 322 MW is the aggregate nameplate capacity of the four principal generating units (FERC, 2024 regulatory reporting). These figures should not be treated as interchangeable but represent different scoping. The 286 MW figure is selected as the facility's power rating; the conflict row documents the distinction. The April 2018 Axium announcement concerns acquisition of 100% of Brooklyn Navy Yard Cogeneration Partners, L.P., the project company. The sale price was expressly not disclosed. Operis and IPP Journal report the July 24, 2018 closing date. Acquisition financing (US$322.5M senior secured, US$30M letter-of-credit facility, US$82.125M subordinated) is documented by IPP Journal and Operis, but this is financing for the acquisition structure, not the purchase consideration. These amounts should not be confused with acquisition price. Equipment: Two Siemens V84.2 (SGT6-2000E) gas turbines at 121 MW each, two Siemens SST-800 steam turbines at 40 MW each, Siemens generators and controls, and two emergency generators. Permit identifies V84.2 designation; project profiles and service announcements identify SGT6-2000E model. The facility was reported operating and generating through 2024. No separate retirement, repowering, or fuel-conversion event for the exact EIA 54914 asset was identified. 2024 ownership as reported by New York PSC: Axium BNY LLC 58.4%, Mission Energy New York, Inc. 41.6%. Both are recorded as joint owners of all four principal generators. Power purchase agreement reports 40-year term from 1996 start. Axium's 2018 release noted 18 years of remaining contract life at that date, which is consistent with a 40-year term beginning in 1996. Hurricane Sandy outage (late 2012) resulted in force majeure declarations, approximately $70.6 million of additional LOC debt, and approximately $15 million of restart capital. S&P base case assumed January 2013 restart; plant returned to operation by at least mid-2013. Service announcement describes performance enhancements including Si3D turbine blade technology and Advanced Compressor Mass Flow (CMF+) modifications. All material facts, relationships, and party identities are supported by at least one authoritative source (regulatory permits, official project website, official acquisition release, or published financial/transaction documents).
