Edison International
A holding company whose main business is Southern California Edison, one of the largest electric utilities in the United States, delivering power to millions of homes and businesses across a vast stretch of California. Its roots reach back to July 4, 1886, when a small partnership called Holt and Knupps used a wood-fired steam engine to light arc lamps for a holiday celebration in Visalia. The "Edison" name comes from inventor Thomas Edison, who let utilities use his name in exchange for his electrical patents.
