Southern California Edison (SCE) Tehachapi Renewable Transmission Project Chino Hills Undergrounding

Chino Hills, CA

Cordoba Corp provides highly specialized underground cable splicing experts to assist with quality control and technology application oversight. The work includes source inspection of tooling and materials and the verification of installation processes. In addition, Cordoba also provided civil inspectors to assist the prime contractor, Burns and McDonnell with on site quality control.

The Chino Hills Underground Project is one component of Southern California Edison’s (SCE) Tehachapi Renewable Transmission Project, which will deliver electricity from new wind farms in the Tehachapi area to SCE customers and the California transmission grid. The Tehachapi Renewal project includes constructing new and upgraded electric transmission lines and substations between eastern Kern County and San Bernardino County. The project’s ultimate goals is to enable California to reach its renewable energy goal of 33 percent by the year 2020.

Part of delivering this energy requires the construction of underground transmission channels including under Chino Hills, located in San Bernardino County. Work in Chino Hills includes the installation of an underground 66kV subtransmission line and related grading operations for access roads and pads. Two transition stations will also be installed.
