Salt River Project (SRP) has filed an application for a Certificate of Environmental Compatibility (CEC) with the Arizona Corporation Commission (ACC) for its proposed South Mountain Transmission (SMT) Project.

SRP will present all the route options including the preferred routes to the Arizona Power Plant and Transmission Line Siting Committee in a hearing beginning on November 12. Public comment will be taken during a special evening session at 5:30 p.m. on Tuesday, November 12, 2024. Participation is permitted via telephone, Zoom, or in person.

The City of Phoenix is planning for development in Laveen, which could include a mix of land uses such as an industrial and tech park, retail offerings, hospitals, hotels and resorts, residential areas, and other new businesses. The SMT Project is intended to support anticipated growth and development along Loop 202 in the Laveen area and to strengthen SRP’s overall transmission system reliability.

To meet anticipated energy needs for the proposed development, SRP plans to build a new 500/230/69 kV substation, together with 2-3 miles of new overhead double-circuit 230-kilovolt (kV) transmission lines and less than one mile of new overhead 500kV transmission lines.

SRP hosted several open houses and stakeholder meetings to gather public input on the SMT Project. The input received throughout the public process was analyzed to inform SRP’s preferred routes. SRP originally proposed the project this past May.
