Commercial-operation timing is reported as August 31, 2010 by the EPC record and as September 2010 by ECP and other project sources; the August 31 date is more precise and is used as the supported value. The plant's leased site area is 40 acres, identified by BASF as the portion of its former 90-acre Rensselaer property leased to Empire Generating Company for power plant operations. A 2019 bankruptcy restructuring followed. The plant is identified as an exempt wholesale generator (FERC docket 07-37-000) and participates in NYISO wholesale markets as a merchant generation resource. NYISO identifiers include the plant's two market-generator units (Empire_CC1 with ID 323656 and Empire_CC2 with ID 323658) and the resource ID R1315. The reviewed evidence does not document a subsequent expansion, repowering, or retirement of this exact Rensselaer facility through the most recent status date of March 2026. The plant is modeled as an operating resource in NYISO's 2025 deliverability study. The 2019 bankruptcy materials support a lender credit-bid restructuring and transfer of control to secured lenders, but the retrieved evidence does not provide the complete post-bankruptcy legal ownership chain. --- Canonical page: https://askthegrid.com/nyiso/assets/plant/empire-generating-co-llc Source: Ask the Grid — https://askthegrid.com/
