APS was named as one of the world’s “Top 100 Green Utilities” in an annual report released by Energy Intelligence, a global independent energy news and research provider.

In its first appearance on the annual list published in EI New Energy, APS was ranked 71st. It is represented under its parent company’s name, Pinnacle West Capital. A total of 25 U.S. organizations made the list, including investor-owned and public utilities, and independent power producers.

“Our inclusion on this list reflects a concerted, long-term effort to make smart investments in a cleaner grid,” said APS President Jeff Guldner. “The electricity we provide our customers is 50 percent clean and getting cleaner. We operate Palo Verde Generating Station, the nation’s largest carbon-free energy producer; and in the coming years, we plan to add more renewable energy, new electric vehicle infrastructure and energy storage technology that maximizes every megawatt generated to reliably meet customer demand.”

For its eighth annual list, Energy Intelligence evaluated each power producer’s “greenness” according to carbon dioxide emissions per megawatt hour of electricity produced, volume of renewable energy capacity and proportion of renewables to total capacity.

The 100 companies represent approximately 45 percent of the world’s power generating capacity across five continents.
