Trans Lines1Since IID’s inception, the utility has put customers first. Because of this, our rates, policies and services have been tailor made to community. From our humble beginnings as a rural power provider, to a modern and innovative consumer-owned resource, IID has become the sixth largest electrical utility in California proudly serving more than 150,000 customers.

IID is currently capitalizing on new technologies, securing affordable energy resources, expanding our capacity for local generation and strengthening our power delivery system—all the while caring for the environment. As a vital public power institution, we are able to deliver incredible advantages, and outstanding value to everyone we serve.

We emphasize environmentally friendly operations by employing as many “green” resources as available and our diverse resource portfolio provides customers with some of the lowest rates in Southern California.
