Cloverdale Expansion Project

The Cloverdale Expansion Project will be built near the existing Cloverdale substation and includes three new 345-kV transmission lines and one new 500-kV transmission line; the partial relocation of an existing 765-kV transmission line, an existing 500-kV transmission line and two existing 138-kV transmission lines; and improvements to the Cloverdale substation, including the construction of a new 500-kV yard to serve as the terminus for the relocated 500-kV line. Construction began in March 2015, while this project is expected to be completed by summer 2017.
