U.S. Energy Secretary Steven Chu this week announced a conditional commitment to provide a partial guarantee for a $1.3 billion loan in support of Caithness Energy's 845-MW Shepherd's Flat project in eastern Oregon. The $1.3 billion loan is expected to be funded by a group of institutional investors and commercial banks led by Citi, as lender-applicant and joint lead arranger, and three other joint lead arrangers: the Bank of Tokyo-Mitsubishi UFJ, Ltd., RBS Securities and WestLB Securities, Inc.
