Resource Planning

Safe, reliable power for the future

Tucson Electric Power (TEP) is diversifying its portfolio of resources in response to new environmental regulations, emerging technology and changes in our customers’ energy needs.  To inform regulators, customers and other interested stakeholders about these and other changes, TEP and its sister company, UniSource Energy Services (UES), have developed Integrated Resource Plans (IRPs).   These IRPs present the detailed assumptions and analyses used to develop the companies’ strategies for serving customers’ long-term energy needs.

TEP filed its 2017 IRP with the Arizona Corporation Commission on April 3, 2017. This IRP covers the period from 2017 through 2032.
