- Financing summary: Kendall’s project financing was refinanced on October 7, 2005 with an eight-year $422 million senior secured term loan facility and a six-year $10 million senior secured liquidity facility. The December 2004 acquisition of the Kendall entities was partially funded with debt and owner capital contributions. Separately, the September 2006 conditional Kendall purchase agreement contemplated $200 million in cash for the equity plus approximately $400 million of project debt at year-end; this was sale consideration and assumed project debt, not a new construction-financing facility. The transaction that actually closed on April 2, 2007 was the broader Dynegy-LS Power portfolio merger, under which LS entities received 340 million Dynegy shares, $100 million in cash and a $275 million note, while Dynegy assumed approximately $1.8 billion of LS Power net debt. — Dynegy Announces Agreement to Combine Operating Assets and Establish Development Joint Venture with LS Power - LS Power · confidence: high

## Data quality

- Early development materials described the project as 1,100 MW, while the 2006 transaction announcement described it as 1,160 MW and later project records report 1,256 MW; these figures should not be treated as proof of a discrete expansion without additional plant-level documentation. The original construction record identifies engineering, procurement and construction contracts with National Energy Production Company and Dick Corporation, while later project-profile material identifies SNC-Lavalin Group as the EPC contractor; the relationship may reflect different contracting scopes or project phases. No plant-specific retirement or repowering event is established in the cited record through the research cutoff.
