History

Change text size:  T  T  T  ? 

Edison International’s roots lie in Southern California in the 1880s, when various small companies began experimenting with power generation and transmission. Pioneers and people of vision led California into the new 20th century. From that collaboration came innovation and the founding of a new industry.

That is the heritage we claim at Edison International; a legacy driven by integrity, excellence and respect that have made historical firsts possible, and that will continue to bring value to our customers and communities for the next 100 years.
