Siemens and TRC Help Central Arizona Utility Get Ready for AMI 2.0
July 29, 2025
Siemens and TRC Companies (TRC) have teamed up to help Tempe (Ariz.)-based Salt River Project (SRP) utility replace its legacy Meter Data Management System (MDMS) with Siemens’ Gridscale X Meter Data Management software.
This modern Advanced Metering Infrastructure (AMI) 2.0 MDMS provides SRP with greater functionality, scalability, performance, and insight into its end user energy consumption patterns. Most importantly, it will allow the utility to progress along its AMI 2.0 journey while enhancing data collection, accuracy, and analysis capabilities. The global strategy, consulting, and engineering services firm TRC provided full solution delivery from strategy to implementation, data migration, and integration services.
One of the largest utilities in Arizona, SRP provides electricity to approximately 1.5 million customers in the greater Phoenix metropolitan area, with a utility service area spanning roughly 2,900 square miles. In recent years, electrical demands continue to grow with increasing numbers of residents and businesses as well as higher energy use consumers like data centers and electric vehicle charging stations.
“Meter data management software is critical to any utility’s advanced metering infrastructure journey,” said Sabine Erlinghagen, CEO of Siemens Grid Software. “It is a crucial piece of the puzzle to enable flexibility and future-proofing as the utility’s needs evolve.”
“We selected TRC and Siemens for their strong technical expertise, industry knowledge, and alignment with our future AMI goals,” said Sheenam Arora, SRP’s Director of Customer Technology. “Their collaborative approach and experience working with utility clients made them an ideal partner for this initiative. Together, we have been able to successfully implement a robust MDMS platform that has strengthened our current metering processes and is a foundation for our future goals in further enhancing data driven decision-making, streamlining metering processes, and ultimately delivering greater value to our customers.”
SRP realized the value of replacing its MDM software with a nimble, scalable solution that could address its current and future needs. The Gridscale X Meter Data Management software can process and manage the vast amount of data received for the utility’s 1.2 million customers upon installation, integrate with SRP’s data warehouse and customer portal, and improve data integrity to enhance operations. This upgrade also lays the foundation for implementing Gridscale X Meter Data Management software with SRP’s future SAP S/4 CIS.
Siemens’ Gridscale X Meter Data Management software is recognized for being modern, scalable, high performing, and functional. Its interoperability makes point-to-point data conversions from various metering systems feasible, enabling integration with more network connections and platforms. The software allows for data from distributed energy resources (DERs) to be aggregated for improved production and consumption transparency, with near real-time monitoring to help manage load. The MDM software can also be a helpful “system of record” tool, if needed for historic or regulatory compliance purposes.
“TRC brings deep utility knowledge and understanding of technology integrations,” said Craig Cavanaugh, President of Digital Solutions at TRC. “Combined with Siemens’ advanced meter data management software, we are helping SRP reach its sustainability and reliability goals, ultimately providing better service to its customers.”
