W, AMI Feasibility Report I Client Name: City of Santa Ana The AMI system can be used to perform improved meter asset monitoring at hourly intervals and data can be analyzed by business processes established in the MDMS. This will assist in identifying meters with potential problems, including stuck meters, zero read, dramatic reductions in usage, etc. The data from all meters can also be aggregated to potentially identify trends across subsets of the meter population, providing early warning of meter quality issues. 7.3 AMI SOLUTION OPERATION In addition to the core water meter work process activities, the implementation of an AMI solution introduces a variety of additional roles and business processes. These are identified as follows and include a proposed organizational structure: o AMI Meter Monitoring - The AMI system collects a vast amount of data in an almost continuous manner. While each meter sends information on a regular basis, the on -request reads: alarms/alerts, and other normal traffic resulting in a continuous stream of data from the meters. This data passes through the network and into the HES. The AMI system will have some automated reports and processes and the City can develop custom reports based on requirements. These must be viewed and acted upon by dedicated staff to ensure the system is functioning properly. A well trained team will identify problems and deliver high quality and complete information to the billing system. Ia AMI Meter Maintenance - In the event monitoring/reports identify a specific meter or group of meters that are not meeting performance levels, staff will try to resolve the issue by remote interrogation of the meter. Depending on the success of this task, a field visit maybe required. The field visit can then resolve the problem (i.e., a customer placed a metal object on top of the meter pit) or the MTU or entire meter/MTU may be replaced. 11 AMI Network Monitoring - Analogous to the AMI system monitoring is the AMI network monitoring. The distinction is that the network monitoring is looking at the performance of the underlying RF network between the meters and collectors, as well as the performance of the backhaul systems. This uses standard telecommunications network management tools and software and/or tools provided by the AMI vendors. This role looks not at the correctness of data or completeness of data but rather the success of data transmission and the network components. ❑ AMI Network Maintenance - Routine maintenance of network devices is required, such as battery check-ups, replacement and visual inspections. More data collection units may have to be added to the network to support new meters that are added in future. While the systems are capable of performing monitoring, upgrading the firmware, or troubleshooting remotely by the network monitoring team, there will be a need for occasional field visits by a communications technician to troubleshoot the system. 7.4 MDMS OPERATIONS AND BILLING SYSTEM SUPPORT TEAM The AMI operations team previously described is responsible for the AMI collection system. However, once the AMI data and operational information is collected by the HES, it will be sent to the MDMS in both real-time and periodic batch processes. The raw meter data enters the MDMS were it is aggregated, preprocessed, and subjected to a multitude of internal business rules and 25G-148
