Resource Planning

Safe, Reliable Power for the Future

UniSource Energy Services is updating its plan for ensuring the continued availability of safe, reliable and affordable energy for customers. The company’s Integrated Resource Plan (IRP) will document our evaluation of available resources and present the detailed assumptions and analyses used to develop our strategy for serving customers’ long-term energy needs.

2020 Integrated Resource Plan

UniSource’s 2019 Preliminary IRP was filed with the Arizona Corporation Commission (ACC) on August 1, 2019. We’re currently engaging key community stakeholders and soliciting customer input for the final 2020 plan, which is due to the ACC on June 26, 2020.

When finalized, the plan will:

  • Describe UniSource’s current resource portfolio.
  • Project future electricity use in communities where UniSource provides electric service.
  • Outline strategies to cost effectively meet customers’ electricity needs over the next 15 years.

Please send feedback on the company’s direction to UniSourceIRP@uesaz.com.
