Southline Transmission Project moves forward

Sponsored by

Southline Transmission said the U.S. Bureau of Land Management (BLM) and Western Area Power Administration have issued a draft environmental impact statement for the proposed Southline Transmission Project.

The publication of the impact statement is a milestone for the project and provides an opportunity for the public to review the potential impacts of the proposed project and to submit comments to BLM and Western.

The Southline Transmission Project is a proposed 360-mile transmission line that would collect and deliver electricity across southern New Mexico and southern Arizona, relieving congestion, strengthening the existing electrical system and improving transmission access for local renewable and other energy sources.

The proposed project consists of two segments:

·      One segment would be a new double-circuit 345-kilovolt (kV) transmission line that would link existing substations at Afton, south of Las Cruces, New Mexico, and Apache, south of Willcox, Arizona; and

·      The other segment would be an upgrade and rebuild of about 120 miles of existing transmission lines from 115-kV to double-circuit 230-kV in order to provide increased capacity to transmit electricity between Apache and the Saguaro Substation, northwest of Tucson, Arizona.
