Cotton Transmission Corridor 500kV/230kV
aps
Voltage: 500kV and 230kV
Estimated Completion Date: 2031/2032
Location: SW Valley Region (Gila Bend, Buckeye, Goodyear and Avondale)
Why this project is needed:
New 230 kilovolt (230kV) and 500 kilovolt (500kV) power lines are needed to improve electrical infrastructure and enhance reliability for current and future APS customers in the Western Maricopa County region. We have begun studies to determine appropriate routes for these lines, which will connect new and existing substations in Gila Bend, Buckeye, Goodyear and Avondale.
Project Details
- Approximately 53 miles of new 230kV and 500kV transmission lines interconnecting multiple substations
- Crosses primarily private, BLM and State Trust Land
- Avoids protected areas, such as the Buckeye Hills Regional Park, Sonoran Desert National Monument and Estrella Mountain Regional Park
- Federal land crossings (BLM) will require undergoing a NEPA process prior to submitting for a CEC with the state.
Project Features
This project will primarily include Monopole (single-pole) structures, but a variety of steel structure types may be used. These structure heights typically range from 130 – 200 feet depending on routing, terrain and crossing of existing structures, including elevated roads and other power lines.
Any opportunity to use existing power line routes for the new structures will be considered. However, new rights of way and/or easements, approximately 120 to 200 feet wide, will be needed.
