Edison is one of the largest electric utilities in the United States and a longtime leader in renewable energy and energy efficiency. With headquarters in Rosemead, Calif., SCE serves more than 14 million people in a 50,000 square-mile area of central, coastal and Southern California. SCE has provided electric service in the region for more than 125 years.

SCE maintains grid assets valued at more than $20 billion, including 1.4 million power poles, 700,000 transformers and 103,000 miles of distribution and transmission lines.

In the past 5 years, SCE’s energy efficiency programs have helped customers save enough energy to power 1.2 million homes for a year.

SCE delivered approximately 15 billion kilowatt-hours of renewable power to its customers in 2012. That’s nearly 20 percent of all the electricity delivered that year — and more than any other U.S. utility.

Now known as Eversource.
