In commercial operation since March 17, 1993, the COTP is an integral part of the California-Oregon Intertie (COI). The Project is rated at 1600-MW and consists of two substations (Olinda and Tracy), and one series-compensation station (Maxwell).
The Olinda Substation near Redding, California includes facilities to interconnect the Project to the Western Area Power Administration’s (Western) 230-kV transmission system through an 850-MVA transformer bank. At Tracy Substation, there are two similar transformer banks interconnecting the Project to Western, each of which has a capacity of 850-MVA.
The COTP participants include TANC, Western, PG&E, City of Redding, Carmichael Water District, and San Juan Water District. The Project has been operating reliably since being placed in operation. Operations and maintenance services are provided by Western.
