Wind is now the largest source of renewable energy in the country, and it will play an increasingly prominent role in TEP’s clean energy portfolio.
With Tucson’s newest and largest solar power system now online, TEP can deliver more solar energy than ever before – including when the sun isn’t shining.

Our Largest Renewable Projects Coming Online for a Cleaner, Greener Grid
This Earth Day, TEP is celebrating our newest and largest wind, solar and energy storage resources, which will soon begin providing clean energy for Southern Arizona.
As we observe Earth Day on April 22, here are four meaningful ways that TEP is doing our part to protect our planet and community.
EV owners visiting downtown Tucson can now get a quick charge from two new fast-charging stations installed in front of TEP’s headquarters.
Sabino Canyon visitors can now purchase shuttle tickets from a solar-powered kiosk designed by UA engineering students.
TEP is working to deliver 70 percent of our energy from renewable sources by 2035, and rooftop solar arrays are a significant part of our plan for a cleaner, greener grid.
