Salt River Project Smart Grid Project

Jump to: navigation, search

The Salt River Project, located in Tempe, Arizona, will receive $200 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected the Salt River Project as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

Salt River Project Agricultural Improvement and Power District’s (SRP) Advanced Data Acquisition and Management Program project involves the installation of smart meters, supporting communication infrastructure, and the expansion of advanced electric service options for customers. Virtually all SRP customers are receiving new smart meters, which monitor electric consumption and power quality. A two-way communication system relays customer electricity data to the utility, where upgraded software platforms analyze and present the data. SRP expects the smart meters to reduce meter-reading costs and field service visits, lower vehicle emissions, and enable development of advanced electric services for customers. These services include a Web portal and expansion of existing time-of-use rates that empower the customer and enable a lower peak demand for SRP. Charging stations for plug-in electric vehicles and transformer metering are being monitored and evaluated.[3]
