A basic concept behind the Advanced Metering Infrastructure is the ability to collect information from the customer meter. This scenario describes the process of acquiring interval data from the residential meters. The data includes information presently gathered from traditional meters such as accumulated energy, demand, and time-of-use information. The information gathered must be available to multiple clients. These multiple clients could retrieve the data from a meter, a place within the network, or the back office. The electric utility can benefit from installation of AMI by reducing Meter Reading forces (as well as other field personnel) and the supporting infrastructure (buildings, vehicles, etc.), streamlining customer service in such areas as billing inquiries, establishing new service connections, improving billing accuracy, providing advanced energy data for forecasting, procurement and settlement, creating additional tariff options, and tracking customer response to demand response programs. Related to this scenario is gathering newly available data such as net metering, interval energy data, power quality, excessive demand thresholds, results of meter self-test status, and other meter event messages.
This use case does not specify the actual end users of the data, but they may include the billing system, ISO, ESPs, meter reading agents, load research, forecasting and settlements, outage management systems, building management systems, distribution operators, maintenance, markets, and customer service. Clients may read data for multiple purposes, including periodic billing, off-cycle billing, outage verification, high bill complaints (or other customer service issues), building automation, bill disaggregating, or local energy management. This scenario excludes gathering of data from customer premise sensors behind the meter (that is covered in case C4).
