Title

PG&E's Moraga-Oakland X 115 Kilovolt Rebuild Project

Description

The Project would involve proposed upgrades to approximately 5-miles of four overhead 115 kV power lines between Moraga and Oakland X substations in the City of Orinda, unincorporated areas of Contra Costa County, and the cities of Oakland and Piedmont within Alameda County. The two existing parallel double-circuit power lines are located within existing PG&E land rights, and the Project would rebuild the four overhead lines into four hybrid lines, with both overhead (~4 miles) and underground (~1 mile) segments. Existing towers, poles and conductors would be replaced either with overhead rebuild or underground components, and minor modifications would occur within the existing substations. Some recently replaced power line structures would be reused or reused with some modification. Single circuit transition structures would support the connection between the overhead and underground portions of each line. Double-circuit transition structures would be used to connect the underground portion to existing overhead line terminals at Oakland X Substation. Additionally, the rebuild would include the installation of optical ground wire on aboveground structures with a communication cable continuing within the underground portion.
