Western Area Power Administration (WAPA) and the Sacramento Municipal Utility District (SMUD) are studying the potential to build a new 500-kilovolt transmission line. The proposed Colusa-Sutter Transmission Line (CoSu Line) would provide a new link between the California-Oregon Transmission Project (COTP) and SMUD and WAPA's facilities on the east side of the Sacramento Valley. The proposed project would enhance the reliability of the electrical grid in Northern California and increase SMUD's ability to import power from the Pacific Northwest and export power from the Sacramento area.
Announcement - September 5, 2017
WAPA and SMUD are beginning to develop the Draft Environmental Impact Statement/Environmental Impact Report (Draft EIS/EIR) for the CoSu Line. Part of this effort includes requesting temporary right-of-entry to perform studies. Starting in September 2017, WAPA will contact landowners to explain this process and to request temporary right-of-entry for properties in the Northern Corridor and Segment 1 Alternative Study Areas. Visit the Frequently Asked Questions page for further information related to right-of-entry.
