We studied making system upgrades to the existing 115- and 230-kV transmission lines in this area, but these upgrades would not provide the added reliability, stability and flexibility that a new 500-kV line would. Adding additional 115- and 230-kV transmission lines and substations would add more total miles of transmission line upgrades than are being proposed with the I-5 Corridor Reinforcement Project.
