Grid United and Black Forest Partners are co-developing the Southline Transmission Project (Southline), a 280-mile, double-circuit, high voltage transmission line and associated substation facilities. The design provides the capability to transport power bi-directionally and will enable wind and solar resources from the Desert Southwest to reach key markets while improving the grid reliability of the border region. Southline will connect the electrical transmission systems of the El Paso and Tucson metropol
Southline will be up to 280 miles long, connecting the electrical systems of the El Paso and Tucson metropolitan areas via the Afton, New Mexico, Apache, Arizona, and Vail, Arizona substations. The Project will enable substantial renewable development opportunities and be an outlet for abundant generation by providing access to new markets.
Southline has already successfully completed a highly complex, multi-year federal and state regulatory process through which all major state and Federal permits have been obtained. Southline’s Final Environmental Impact Statement was published in October 2015. Bureau of Land Management (BLM) and Western Area Power Administration (WAPA) Records of Decision were published in April 2016. The Arizona and New Mexico state siting processes were completed in February 2017 and August 2017 respectively. The Project
