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.
WAPA and SMUD have posted the scoping report that includes copies of the public comments from the 2015-2016 scoping period and the 2017 scoping period, and describes the activities conducted during the public scoping period. The scoping report will inform the analysis of the Draft Environmental Impact Statement/Environmental Impact Report. The scoping report can be viewed online or at local libraries.
