Bianco 230kV Transmission Line Siting Project
aps
Voltage: 69kV, 230kV and 500kV
Estimated Siting Completion Date: Q1 2026
Location: Casa Grande and unincorporated Pinal County
Why this project is needed:
To meet the expanding energy needs of more people and businesses throughout the Casa Grande area, we are looking to upgrade our system. We have started studies to determine appropriate routes for new transmission lines and a new substation in the Casa Grande and Pinal County area. These facilities will connect with existing transmission infrastructure and include 69kV, 230kV and 500kV facilities. We are working to identify locations for the new lines to best meet the needs of our customers and the community.
