About the Transmission LIne

The Mead-Adelanto Transmission Project is a 202-mile, 500 kV AC transmission line with a rating of 1,291 MW. This transmission line runs from the existing Adelanto Substation in southern California to the Marketplace Substation near Boulder City, Nevada.

SCPPA Participation

SCPPA's original capacity of the transmission line is 877 MW, bringing in energy from Nevada based projects. In 2015, SCPPA purchased additional capacity on behalf of LADWP.  By connecting to the Marketplace Substation, the transmission line also interconnects with the Mead-Phoenix Transmission Project and the McCullough Substation in southern Nevada. This connection makes it possible for SCPPA participants to receive the energy from projects in Arizona as well.
