The discrepancy reflects different capacity definitions (project vs. nameplate vs. seasonal). The 48 MW project figure is used in the public description as the most directly attributable to the official project source. The facility operates one GE LM6000 PC Sprint turbine. The permit and project records each independently confirm one unit, and neither source indicates multiple turbines or a phased expansion. A deactivation notice submitted on October 31, 2016 was withdrawn on September 18, 2017, with J-Power USA stating its intention to continue operating the unit. No subsequent retirement or repowering event was identified through the query date. The August 1, 2024 transaction announcement described an agreement to acquire a four-plant portfolio providing approximately 300 MW. The January 30, 2025 announcement confirmed the transaction had closed with Hull Street Energy acquiring 100% of the four plants. No plant-specific purchase price, consideration, or financing terms were disclosed in either announcement. No project-specific financing agreement, lender, principal amount, or financing close date was identified in the candidate research. A 2004 NYISO study included analytical assumptions that such plants would be financed on the parent company's balance sheet; those were study assumptions, not evidence of actual Equus financing. The exact asset is distinguished from other Equus, Freeport, or Long Island resources by EIA plant code 56032, EIA utility code 49845, EIA generator code 0001, NYISO unit identifier GT1, and the single 289 Buffalo Avenue address with one GE LM6000 configuration. The plant record indicates generation data through December 2024 and status as 'Operating,' with no retirement or mothballing date identified. - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] - Open question: [object Object] --- Canonical page: https://askthegrid.com/nyiso/assets/plant/equus-freeport-power Source: Ask the Grid — https://askthegrid.com/
