Our 2023 Integrated Resource Plan

Ambitious. Realistic. Responsible.

Our customers’ energy needs are growing, with new peak energy demand records set in both 2020 and 2021. UniSource Energy Services is working to meet those needs with an increasingly clean energy resource mix.

The plan considers alternative combinations of demand-side resources, such as energy efficiency, load management and demand response and supply-side resources, including traditional and renewable power plants, to identify the best portfolio of resources for meeting customer energy needs in a safe, reliable, sustainable and affordable manner.

The IRP will provide a roadmap for balancing these objectives while also considering risks and uncertainties inherent in any long-term planning process.

All-Source Request for Proposals

Building on our commitment to meet customers’ energy needs reliably while expanding our clean energy resources, UniSource is evaluating options to add energy, capacity and renewable systems to the company’s portfolio. UniSource and its sister company, Tucson Electric Power, issued an all-source request for proposals (ASRFP) in April 2022, seeking new wind and solar generation, energy storage systems and other resources.
