Salt River Project


Salt River Project (SRP) is the third-largest public power utility in the United States, serving more than 935,000 electricity customers in the greater Phoenix, Arizona metropolitan area through a variety of resources, including solar, wind, biomass, geothermal, hydroelectricity, natural gas, coal and nuclear. The utility operates or participates in 11 major power plants, and provides electricity to residential and commercial customers across more than 2,900 square miles.

Truck rolls related to meter readings, meter connects/disconnects and general services represent significant operational costs to SRP. The utility hoped to automate these processes and offer expanded customer services such as time-of-use (TOU) pricing by deploying one of the nation’s first Advanced Metering Infrastructure (AMI) Smart Grid projects.

“We didn’t want to learn about AMI by reading about what other utilities were doing with the technology, so we began working with the Elster EnergyAxis® solution in 2004. We saw such significant benefits to cost-savings and operations, we doubled our EnergyAxis deployment in 2010,” said Scott Trout, Manager of SRP’s Federal Stimulus Program.
