Lead lenders include Credit Suisse First Boston, Commerzbank and Union Bank of California. Credit ratings of A- and Baa1 were received from Standard & Poor's and Moody's, respectively. "By closing the financing on this important project in the current economic climate, Kern River and its lenders have once again affirmed Kern River's unique position and critical value to a growing and dynamic natural gas market in California, Nevada and Utah," said Robert Sluder, president of Kern River. The $1.2 billion expansion project will be financed with 70 percent debt and 30 percent equity. The 2003 expansion will more than double the amount of natural gas transported on the Kern River system. The project includes placing a second natural gas pipeline in the right-of-way adjacent to the existing pipeline, constructing three new compressor stations and installing additional compression and modifications at six existing facilities. When completed, the Kern River system will be able to transport approximately 1.7 billion cubic feet per day. Kern River has executed binding agreements with shippers for over 900 million cubic feet per day of incremental service. It is anticipated the Federal Energy Regulatory Commission will issue final approvals in time for construction to begin in summer 2002 to meet a May 1, 2003, facilities in-service date.
