The Colusa-Sutter Transmission Line (CoSu) is a planned 500-kV transmission line within Colusa and Sutter counties, CA. The project, which will be a new pathway for renewable energy flow, would interconnect the California-Oregon Transmission Project (COTP) transmission system, near either Arbuckle or Maxwell, California, to the Central Valley Project (CVP) transmission system near Yuba City, California. According to THUB calculations, the project has an estimated cost of $60m.
