New Rates to Support Reliable, Sustainable Electric Service

Tucson Electric Power is seeking updated rates to support development of a smarter, greener grid to serve our community's growing energy needs.

TEP's current rates do not reflect approximately $1.2 billion our company has invested since June 2015 to maintain and improve service while transitioning to a cleaner, more flexible and resilient energy portfolio. We are expanding our energy resources, updating our grid and working to more than double our use of wind and solar power by 2021.

The Arizona Corporation Commission (ACC) is reviewing this request and is expected to vote on the proposal later this year.
