## Data quality

- Capacity discrepancy: EIA-aligned plant record reports 100 MW nameplate; New York DEC permit reports 95 MW maximum electrical output; former owner's project page reports 90 MW. All three sources are authoritative for their respective jurisdictions/contexts. The 100 MW EIA value is selected as the facility-level nameplate rating; operating capacity may be lower. Fuel designation discrepancy: Official project page lists 'JET-A fueled' while New York environmental permit and plant record list 'distillate oil' and 'Oil'. These terms refer to the same fuel type (Jet-A is a type of distillate fuel), so this is a semantic rather than substantive conflict. No separate construction-start date, EPC contractor, or construction financing amount was identified in the retrieved sources. The plant entered service in August 2002 under PPL ownership. Power-purchase agreement with Long Island Power Authority expired in August 2017; no post-2017 offtake arrangement was identified in the retrieved sources. No documented expansion, retirement, or repowering event for the facility was found in the retrieved sources; the plant continues to operate its original two-turbine simple-cycle configuration.
