COTP California Oregon Transmission Project

Transmission Agency of Northern California (TANC), a joint powers agency that worked in partnership to finance and construct the Harold T. Johnson Intertie, also known as the California Oregon Transmission Project (COTP) – added 1600 MW (at 500-kilovolts) of transmission capability between the Pacific Northwest and California. The telecommunications aspect of the project, completed in late 1992, consisted of 34 microwave sites, three optical terminals, with SCADA, telephony, 56-kb power control, and network infrastructure. SCCI served as the engineering and design sub-contractor to L & R Communications, the prime communication contractor (EF&I) for COTP.
