Saguaro to Marana 115/138 Kilovolt Transmission Line Project
Tucson Electric Power (TEP) and Arizona Electric Power Cooperative (AEPCO) are planning new electrical infrastructure to serve the Town of Marana and surrounding area. The Saguaro to Marana 115/138- Kilovolt (kV) Transmission Line Project will strengthen electric reliability and add transmission capacity to serve customers’ growing energy needs.
The Arizona Power Plant & Transmission Line Siting Committee granted Arizona Electric Power Cooperative’s application for a certificate of environmental compatibility (CEC) in June 2022. The CEC must be reviewed and approved by the Arizona Corporation Commission before construction can begin.
The unnamed TEP substation is planned to be in-service in 2026. This date may change depending upon energy demand within the project area.
