The state’s regulated electric utilities are on track to meet the goal of 6 percent renewable energy use by the end of 2016, largely through utility-scale and rooftop solar projects.
In 2006, the Arizona Corporation Commission approved the Renewable Energy Standard and Tariff (REST), a rule that requires regulated electric utilities to generate 15 percent of their energy mix from renewable resources like solar, wind and biogas by 2025.
The rule steps up the amount each year, starting at 1.25 percent in 2006 and gradually moving to 15 percent. From 2016 forward, the amount will increase by 1 percent each year until it reaches 15 percent.
