Teun Valstar

Teun Valstar is an invaluable technical expert on electric transmission line projects, including underground transmission line projects.  With his knowledge of fabrication, quality control and field application of new technologies, he has provided expertise on several important 138 kilovolt (kV), 230 kV and 500 kV transmission line projects for investor-owned utilities in Southern California. He is skilled at training and managing transmission crews and is adept at high-voltage splicing and testing.

Teun represented Cordoba Corporation as a member of the team supporting the construction of Southern California Edison’s Tehachapi Renewable Transmission Project’s (TRTP) underground 500 kV segment through Chino Hills.  Since undergrounding of transmission lines of this voltage is not common in the United States, this work required specialized expertise.  Teun provided highly specialized underground cable splicing expertise on TRTP.  His work included source inspection of tooling and materials, as well as the verification of installation processes.  He served as a lead quality control inspector and was involved with conduit proofing, cable pulling, splicing, testing and commissioning.

Teun has also represented Cordoba Corporation on several San Diego Gas & Electric (SDG&E) transmission and substation projects, including the East County Substation Project, which involved 12 miles of underground 138 kV transmission line work; the South Bay Substation Relocation Project, which involved the extension of an existing 230 kV transmission line; and several other smaller projects. He is currently providing support to SDG&E on the Sycamore-Penasquitos 230 kV Transmission Project, which involves a new 12-mile underground 230 kV transmission line.

Prior to joining Cordoba Corporation, Teun worked for a large cable manufacturer, where he served as a splicer, drafter, and a field supervisor.
