## Data quality

- The asset is uniquely identified by EIA plant ID 58777, NYISO Service Agreement No. 2475, FERC docket ER20-2202-000, and New York Article 10 case 14-F-0490. Capacity varies slightly across authoritative sources: EIA plant record reports 124 MW, RWE marketing materials report 125 MW, NYISO interconnection filing reports 126 MW, and New York DPS regulatory affidavit reports 125.5 MW (the weighted sum of individual turbine ratings). The 125.5 MW figure is the most precise and is selected as the standard capacity value. The investment figure of more than $200 million is explicitly reported by RWE as project investment in Chautauqua County and should not be confused with the approximately $67.9 million merger-agreement milestone payment to Trireme, which was tied to commercial-operation timing under a separate predecessor transaction. No project-specific lender, debt facility name, debt amount, or separately disclosed tax-equity investor was identified in the reviewed authoritative sources. Financing context is documented at the corporate and acquisition level (Innogy financing the IRUS acquisition and construction), but no named project-level finance structure was found. Interconnection point details may reflect changes from the 2019 LGIA filing, which identified Laona-Falconer Lines 172 and 173.
