Keeping Arizona On Like you, we call Arizona home. That’s why we’re advancing the state’s clean energy future. Our energy mix is already 50 percent clean. Today, we have 10 large-scale solar plants and more than 1 million solar panels across the state. Adding innovative battery storage at our solar plants makes solar available late in the afternoon and at night. These are just some of the ways we’re keeping Arizona’s power clean, reliable and affordable for today and tomorrow.
