## Data quality

- Capacity figures vary by rating and source: EIA-linked inventory reports 1,232 MW nameplate capacity, 1,206.7 MW summer capacity, and 1,288 MW winter capacity; Talen reports 1,120 MW of owned generating capacity; historical transaction sources report ratings ranging from 1,096 MW to 1,186 MW. These figures appear to reflect different rating conventions rather than different facilities. Talen describes the configuration as four gas turbines and two steam turbines, while the EIA-linked inventory counts six generators. The generator count is reported from the source and is not inferred from capacity. The reviewed exact-plant sources document no expansion, repowering, or retirement milestone; the facility is reported as operational. The 2017 $2.1 billion figure was consideration for a four-plant portfolio, and the 2026 $3.45 billion figure was consideration for a three-asset portfolio, not Lawrenceburg-only sale consideration.
