## Data quality

- The project identity is tied to EIA plant ID 56953 and the official project name High Sheldon Wind Farm; New York regulatory records and Invenergy announcements consistently use this name. The 112.5 MW capacity and 75 GE 1.5sle turbine count are confirmed by multiple authoritative sources: Invenergy official announcements, New York PSC filings, and independent third-party sources. The PSC-sourced date of March 12, 2009 is used as the most authoritative. The January 6, 2009 financing closed for a portfolio (Coastal States Wind Holdings LLC) that included High Sheldon. No High Sheldon-specific financing amount is disclosed in the sources. The $6.4 million figure in the PSC record refers to Sheldon's estimated installed cost of the interconnection facilities transferred to NYSEG, not project-level financing or sale consideration for the wind farm. The 2011–2012 interconnection-facilities transfer (Case 11-E-0619) is well-documented. The PSC order header indicates a February 16, 2012 session but states the order is issued and effective February 22, 2011; this internal inconsistency is noted but does not affect the substantive accuracy of the transfer details. No wind-farm acquisition, sale of the generation asset, expansion, retirement, or repowering transaction was identified in official owner or regulatory records. Sheldon Energy LLC retained ownership of the generation-side facilities between the wind turbines and the point of change of control to NYSEG; Sheldon continues to operate the wind farm.
