## Data quality

- Capacity varies by reporting basis: the DRBC describes the facility as 600 MW, EIA/FERC generator records total 614 MW of nameplate capacity, and Vistra’s Pennsylvania profile lists 607 MW. The April 2015 consideration of approximately $3.35 billion in cash plus $105 million of Dynegy common stock was aggregate consideration for the EquiPower and Brayton portfolio transaction, not a Liberty-only sale price. The documented financing-related history is a distressed-debt restructuring that transferred ownership to Strategic Value Partners by mid-2007; no separate plant-level construction-financing amount or lender is disclosed in the cited records.
