26 <br />AMI Feasibility Report I Client Name: City of Santa Ana <br />0 New meter asset information and the need to allow for a meter number and an associated AMI <br />MTU, the two have to be distinct and able to be separated to allow MTUs to be retrofitted on <br />existing in-service meters and to be replaced when faulty without replacing the meter. <br />0 During the AMI deployment process, there will inevitably be data errors that are discovered and <br />while identifying and resolving them will be valuable, it will consume some resources. These <br />errors include discrepancies of meter IDs and reading, swapped meters in multi -family dwellings, <br />found meters not in the system, meters in the system that are no longer in service, incorrect <br />addresses, etc. <br />0 The availability of the meter data from the MOMS is very useful to call center representatives in <br />responding to customer inquiries, and normally, the capability to obtain the meter data while <br />remaining within the billing system application or popping out to a specific screen is desired. <br />0 There will be a significant number of meter exchanges done in a short period of time that may <br />stress the current system and require modifications to batch processing times or management of <br />billing system during implementation period. <br />0 The migration from bi-monthly to monthly billing (if implemented by City in future) for all <br />customers will have a significant impact on billing system operations. <br />0 There is no need for additional hardware, software or resources for Enquesta/billing operations <br />to support the AMI project. However, there will be system integration of AMI and MDMS with <br />Enquesta billing system during the project implementation stage (this work will be completed as <br />part of the AMI project and details are provided later). <br />6.3 SCADA <br />AMI vendors are focusing on water pressure monitoring capability through the AMI system to assist <br />utilities in improving services and operations. Some water meter vendors are looking to capture <br />pressure at the customer meters, and these data will eventually be available through the AMI <br />systems. Of considerable interest is the ability to connect pressure devices on the distribution <br />system onto the AMI network so that they can retrieve the data over the AMI network. The data can <br />then be passed over to the SCADA system and/or captured in a data storage solution. The AMI - <br />enabled pressure monitoring would likely have a lower cost than traditional SCADA-connected <br />solutions, which could allow City to install a larger number of remote pressure monitoring devices <br />if required. <br />6.4 CUSTOMER WEB SERVICES <br />The AMI system will provide hourly usage data, leak notification and alarms on all customer <br />meters. This can be leveraged to support a set of customer self-service and engagement initiatives. <br />Many utilities leverage their web portal to serve graphs and usage information from the MOMS. <br />These solutions can be modules of the MOMS, AMI vendor analytics solutions or free -standing <br />solutions. They most often are branded to match the utility's web presence so that they appear <br />integrated. These solutions can result in a large increase in the data being presented across the web <br />portal and often require additional investments in portal hardware and systems. <br />25G-144 <br />
