TEP plans to build a new 138 kilovolt (kV) substation and upgrade existing facilities in the Town of Marana to strengthen electric reliability for customers and meet growing electric demand in the area.

Through long-term planning studies, TEP has determined that new infrastructure will be required to strengthen electric reliability and support residential and commercial development in the area. The project will expand transmission capacity to serve customers’ growing energy needs while supporting economic development in the Town of Marana and the retirement of an aging 46-kilovolt (kV)  substation.

If you have any questions, please contact TEP Land Resources Environmental & Land Use Planner Chris Ortiz y Pino at 520-633-8693.
