According to a new analysis released this week by the Solar Electric Power Association, ten American electric utilities accounted for 82 percent of all solar capacity integrated in 2013, up from 73 percent in 2012. The latest rankings show utilities ranked by Watts-per-Customer and Annual Capacity. In both categories, the lists were dominated by utilities located in California and Hawaii. With the release of the latest rankings, Julia Hamm, president and CEO of SEPA noted “It’s truly inspiring to see utility partners and their consumer communities rally around implementing solar programs that are changing the nature of our national energy portfolio.”

Newcomers to the list include Duke Energy Progress, National Grid, and Georgia Power. Pacific Gas and Electric Company let the Annual Capacity list followed by San Diego Gas & Electric Company, Arizona Public Service, and Southern California Edison. According to Steve Malnight, PG&E’s Vice President of Customer Energy Solutions, “Given both PG&E’s large-scale solar procurement and our customers’ ongoing support of solar and other clean technologies, we are confident we will continue to be a renewable energy leader.”
