Resource Planning

UniSource is planning a path toward a cleaner energy future.

UniSource continues its commitment to building a robust mix of resources that includes an expanding portfolio of cost-effective renewable resources and efficient natural gas generation. We will also offer customers new opportunities for energy efficiency and managing peak energy demands. All of these resources will play key roles in ensuring sustainable, responsive service.

In March 2022, the Arizona Corporation Commission reviewed and acknowledged our 2020 Integrated Resource Plan (IRP). The IRP provides regulators, customers and other interested stakeholders with information about current resources, detailed assumptions and analyses about future energy requirements, and strategies for meeting our customers’ long-term energy needs.

UniSource and its sister company, Tucson Electric Power, have initiated the 2023 IRP planning cycle, building on our commitment to meet  customers’ energy needs reliably while increasing our portfolio of clean energy resources.
