Utility Energy Efficiency Programs

Updated: July 2017


Arizona’s population grew 1.18 percent per year on average from 2008 to 2015, while the consumption of electricity increased an average of 0.20 percent per year over the same period. In 2014, energy expenditures per capita were $3,360, which ranked Arizona 50th among all U.S. states. 
The state is served by three primary investor-owned utilities: Arizona Public Service Company (APS), Tucson Electric Power Company (TEP), and UNS Electric. In 2015, APS was the largest electric utility with more than 1.2 million customers in 11 of the 15 counties in the state. TEP served nearly 420,000 customers in southern Arizona. UNS reported more than 92,000 residential and business customers mostly in Mohave and Santa Cruz counties. 
In addition, Salt River Project (SRP) is a private, self-governed corporation serving about 1 million customers (2015) in metro Phoenix and nearby areas. 
Thirteen electric cooperatives also serve customers in Arizona. 
Natural gas is provided by Southwest Gas and UniSource Energy Services.  In 2015, these companies provided natural gas service to more than 1.9 million customers. 
Over the last several years, Arizona's largest utilities have significantly expanded their energy efficiency program offerings.
