Planning ahead for reliable, affordable, and sustainable energy
Tucson Electric Power (TEP) will accelerate its clean energy expansion to support anticipated growth and maintain affordable, reliable service as the company works toward a new aspirational goal: net zero direct greenhouse gas emissions by 2050. Our integrated resource planning process (IRP) provides regulators, customers and other interested stakeholders with information about current resources, analyses about future energy requirements, and strategies for meeting our customers’ long-term energy needs.
The IRP, in conjunction with our all source request for proposals and transmission planning processes, provides guidance as we continue working to reduce carbon dioxide emissions 80 percent by 2035.
2023 Integrated Resource Plan
TEP has filed an IRP with the Arizona Corporation Commission, building on our commitment to meeting customers’ energy needs reliably while increasing our portfolio of clean energy resources. Learn more about the 2023 IRP.
Our Previous IRPs
Greenhouse Gas Emissions Reduction Goal
TEP’s carbon emission reduction goal was developed in partnership with the University of Arizona’s Institute of the Environment with input from a diverse group of customers, community leaders, local government representatives and environmental advocates. The target represents TEP’s fair share of worldwide efforts to limit global warming to well below 2 degrees Celsius under the 2015 Paris Agreement. TEP’s plan would reduce carbon dioxide emissions by 80 percent compared to levels in 2005, a widely used benchmark year in carbon reduction goals.
