SMUD Cogeneration Gas Pipeline Project

The Sacramento Municipal Utility District’s (SMUD) Cogeneration Gas Pipeline project consists of a 64-mile, 20 inch (diameter) buried carbon steel pipe which transports natural gas to four SMUD cogeneration power plants, including the Carson Ice Cogeneration project (92-SPPE-01C), the Sacramento Ethanol and Power Cogeneration (SEPCO) project (92-AFC-02C), the Procter & Gamble Cogeneration Project (93-AFC-02C), and the Campbell Cogeneration Project (93-AFC-03C). The pipeline connects with existing Pacific Gas and Electric gas lines 400 and 401 just north of Winters, in Yolo County, allowing SMUD to purchase Canadian gas.

On September 14, 2007, the California Energy Commission (CEC) approved a Post-Certification Amendment (PCA) (TN 42307) the relocation of an approximately 3,200-foot segment of the existing 20-inch Cogeneration Gas Pipeline (Line 700-A) to make way for the proposed Cosumnes River Boulevard Interchange on Interstate Highway 5.

On April 16, 2009, the CEC approved a PCA (TN 51104) to upgrade the equipment that meters and regulates the natural gas flow and pressure from SMUD’s existing Line 700B to the Sacramento Power Authority’s Campbell Cogeneration Project in South Sacramento. The upgrades included new metering and regulating equipment and the installation of a new control building within the existing Campbell Cogeneration Project. The portion of the pipeline associated with these upgrades is located in Sacramento, Sacramento County.

On July 9, 2009, the CEC approved a PCA (TN 52377) to relocate an approximate 150-foot segment of the existing 20 inch Cogeneration Natural Gas Pipeline (Line 700A) near the intersection of County Road 29 and County Road 102 in Yolo County to restore the pipeline to its original design standards with respect to pipeline operating pressure. The pipeline modifications were necessary because Yolo County realigned County Road 29 subsequently restricting SMUD's future operations with respect to pipeline operating pressure.
