New Mexico Geological Society Annual Spring Meeting — Abstracts

SouthWestern Power Group (SWPG) is the developer of the SunZia Transmission Line Project which originally comprised two, high voltage transmission lines between central New Mexico and central Arizona. The RioSol Transmission Line Project is the second phase of the SunZia Transmission Line project. RioSol is an alternating current (AC) line that will interconnect with three to six utility systems in both states. The line will start in Torrance County, run across to Valencia County, down to Luna County, and terminate in Pinal County. The line will interconnect with 3-5 utilities along the route with opportunities for other interconnections for large scale projects. The project is expected to start construction in late 2026 and start commercial services in late 2028. This presentation will provide the current development status and interconnections plans for the RioSol Project.
