These identifiers separate it from other Castleton-named or nearby facilities. The 2016 transaction was an acquisition of Castleton Power LLC and related ownership interests, not a disclosed project-finance amount. Public transaction coverage and deal-flow reporting do not state a purchase price; the deal-flow record marks the value as undisclosed. The 2018 New York PSC financing approval authorized aggregate indebtedness of up to $200 million for Castleton Power and Lockport Energy Associates jointly. It should not be treated as a Castleton-only project-financing amount. Available plant data continued to identify it as operating. The facility ceased qualified-cogeneration operation in 2002 and became an exempt wholesale generator; it is classified as IPP non-CHP in current EIA and regulatory records. Equipment detail (GE turbine model PG6541B, Deltak HRSG, COEN duct burner, Johnston boiler) is sourced from official NYSDEC permit and EPA technical support documents. Ownership chain is fully documented through regulatory PSC orders and transaction announcements: Cogen Energy Technology (1992–1999) → TransCanada Power (1999–2006) → EPCOR (2006–2009) → Castleton Energy Center/Wayzata (2009–2016) → Fortistar (2016–present). Fortistar Castleton LLC is the acquisition subsidiary through which Fortistar LLC acquired Castleton Power LLC on 2016-07-20. It is a separate legal entity created for the transaction and documented in New York PSC filings. - Open question: [object Object] - Open question: [object Object] --- Canonical page: https://askthegrid.com/nyiso/assets/plant/castleton-energy-center Source: Ask the Grid — https://askthegrid.com/
