## Data quality

- Current EIA-derived plant data reports 1,086.2 MW and 10 generators, while historical transaction documents describe Aurora as 878 MW and the 2026 NRG acquisition filing lists Aurora Generation LLC at 1,050 MW; these figures reflect different rating, reporting, or transaction vintages and should not be treated as interchangeable. Commissioning was staged: site work began in 2000, the first unit is reported online on May 1, 2001, and nine of the 10 turbines were online by June 1, 2001. The current generator record indicates units entered service during 2001-2002. The plant is reported as operational with 10 operational generators. No separate expansion, retirement, or repowering milestone is identified in the cited plant and transaction records.
