## Data quality

- The facility is consistently identified in the cited records as Lockport Energy Associates LP / Lockport Cogeneration Facility, but reported capacity varies: 168.8 MW in the 1992 DOE record, 198 MW in a NYSDEC permit, 200 MW in several PSC filings, 210 MW in the 2026 petition, and approximately 221 MW in current plant records. No single documented event (expansion, retirement, or repowering) explains these differences; they likely reflect different rating conventions (gross vs. net, nameplate vs. design) rather than material changes to the physical facility. The current 221 MW rating is selected as the best-supported exact value in the most current authoritative records. The 2018 PSC financing approval authorized up to $200 million of aggregate indebtedness for Lockport Energy Associates, L.P. and Castleton Power LLC together. The record does not establish that the full amount was drawn, nor does it provide a project-construction loan amount, lender, interest rate, or sale consideration. The 2014 and 2021 ownership matters concern transfers of passive or upstream ownership interests rather than documented sales of the physical generating facility. The April 2026 Castleport transaction is described as proposed in the verified joint petition dated April 14, 2026; the cited record does not establish closing by July 25, 2026. No authoritative record located in the cited corpus documents a distinct expansion, repowering, or retirement of generator LEA1. The available evidence instead supports continuous operation from 1992 through the current records. The NYDEC permit identifies the steam purchaser as a 'nearby steam host.' The 2026 PSC petition explicitly identifies this as the 'General Motors Western New York Lockport Components plant,' which is distinguished from the original 1992 DOE record's reference to 'General Motors' Harrison Radiator Division.' The current recipient entity name is preserved from the most recent authoritative filing. The equipment configuration (three GE Frame 6 CTGs, three HRSGs, one STG, one auxiliary boiler, and three starting diesel engines) is supported by explicit permits issued in 2005 and 2016. No later repowering or equipment changes are documented in the reviewed evidence.
