Henrietta – Gates Transmission Upgrade

The Henrietta-Gates transmission upgrade is a planned addition to an existing 230-kV line. The new 230-kV will run parallel and adjacent for about 11 miles between the new Westlands Solar Park site and the Gates Substation. The planned line is part of the construction of the Westlands Solar Park in Frenso, CA. The facility’s anticipated output will be nearly 2,400 MW which will will need the added carrying capacity for the existing transmission infrastructure.
