Calpine Corp. has ousted Deutsche Bank as lead manager for its $2.3 billion CCFC-II refinancing and is holding talks with rival Wall Street giants Morgan Stanley, Credit Suisse First Boston and Goldman Sachs about taking over the mandate, according to sister publication Power Finance & Risk. Several bankers close to the situation said Calpine is leaning toward hiring Goldman Sachs, but added that Calpine CFO Robert Kelly has yet to ink a contract. A spokesman at Deutsche Bank was unable to provide comment and a Calpine spokeswoman did not return calls. Bankers at CSFB, Goldman and Morgan Stanley declined comment.
