Resource Planning

Safe, reliable energy from increasingly sustainable resources

Tucson Electric Power (TEP) is planning a dramatic expansion of clean energy resources that will allow us to provide 70 percent of our power from renewable resources while reducing carbon dioxide emissions 80 percent by 2035.

This ambitious, realistic vision for a sustainable energy future is detailed in TEP's 2020 Integrated Resource Plan (IRP), filed June 26 with the Arizona Corporation Commission. 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.

Greenhouse Gas Emissions Reduction Goal

TEP’s new 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.

Public Input

An all-day, online virtual workshop was held on May 20, 2020 to gather public input about various resource planning alternatives as TEP sought to develop a plan that would reduce greenhouse gas emissions while allowing the company to continue providing reliable, affordable service to customers. Broad participation in the workshop contributed to a more inclusive resource planning process.

IRP Advisory Council

The electrical grid is undergoing a massive transformation, making integrated resource planning a more complex process that calls for greater stakeholder involvement. As part of the 2020 IRP process, TEP formed an advisory council that provides a forum for in-depth discussions with engaged community stakeholders. Members include residential and business customers, local governments, public schools, limited-income advocates, solar installers and environmental advocates.

TEP believes that a diverse, knowledgeable group of counselors can help chart a long-term plan that helps our community achieve sustainability goals and maintain reliable, affordable electric service through a balanced, flexible resource plan.
