The system also supports additional features and functionality related to system operation and customer service, e.g. outage management, connect/disconnect, etc." AMI requires requisite bandwidth to supply more than merely metering and power quality information. AMI typically provides a substantial payload of information. Usage information, tamper indication, and interval data is available for electric, water and gas meters, along with specific advanced capabilities for electric metering endpoints. Our solution is forward and backward compatible, giving you the capacity for future expansion. Implementing our innovative AMI metering and Demand Response solutions does not require across-the-board equipment replacement and configuration, saving you time and money. FERC defines AMI as “A metering system that records customer consumption hourly or more frequently and that provides for daily or more frequent transmittal of measurements over a communication network to a central collection point.”

As distribution utilities begin deployment of next generation Advanced Metering Infrastructure (AMI) plus systems, a robust communications network is a foundational part of a utility AMI architecture, delivering bidirectional connectivity between smart meters and head-end utility systems. A common initial application utilizing the AMI network is centralized meter reading. This single application provides the utility with many benefits that result in reduced operating costs, improved operational efficiencies, and greater customer satisfaction. Typically an AMI communications network is multi-tiered. Often an RF mesh is used for the tier 3 network, to connect smart meters to a metering collector. Hitachi Energy offers high-performance broadband, narrowband and cellular solutions that can work together to provide utilities with an optimal end-to-end communications network that enables a wide range of smart grid applications and a foundation for the future. Centralized meter reading reduces operational costs: It reduces truck rolls thereby reducing fuels and vehicle maintenance costs; increases meter reading accuracy; enables more timely identification of unaccounted for energy losses. In addition to reading meters, many utilities are embarking on AMI plus, leveraging their AMI communications network to aggregate communications for a variety of applications beyond meter reading. Examples of these applications including remote service connect/disconnect, prepay services, demand-response, time-of-use pricing, power quality monitoring, outage management and more. However, as AMI plus applications are deployed, they place incremental demands upon the tier 2 AMI backhaul network for bandwidth, latency and reliability.

What is advanced metering infrastructure (AMI)?

www.ibm.com

Advanced metering infrastructure (AMI) is an integrated, fixed-network system that enables two-way communication between utilities and customers. The system collects, stores, analyzes and presents energy usage data, providing utility companies the ability to monitor electricity, gas and water usage in real time. Given our growing need for efficient, cost-effective, environmentally sustainable energy—and the increase of smart technology—it’s no surprise that AMI has become a key technology in a broader evolution. Communication networks can transmit usage information to water, gas and electric utilities by using radio frequency signals, cellular networks or broadband connections, or by using power line communication (wherein AMI meters transmit data over power lines). The ability to remotely manage meters not only eliminates the need for manual meter readings, but it also enables faster response times in the event of a power outage. The data management system is the central repository where all meter data is collected, stored, processed and analyzed. Here, raw data from smart meters is converted into actionable insights. The AMI head-end system serves as a hub for incoming data from all installed smart meters. The head-end system verifies the data, performs preliminary processing and then forwards it to the meter data management system (MDMS). When the utility has all the necessary data insights, it relays those insights to the customer, who can then access detailed energy usage information on demand through customer portals and in-home displays. This transparency can sway customer decision-making, encouraging energy-saving behaviors and enabling customers to manage their energy costs more effectively. In the event of an impending outage, AMI systems come equipped with outage management features that can send affected smart meters a "last gasp" signal before power goes out.

Smart meter - Wikipedia

A smart meter is an electronic device that records information—such as consumption of electric energy, voltage levels, current, and power factor—and communicates the information to the consumer and electricity suppliers. Advanced metering infrastructure (AMI) differs from automatic meter reading (AMR) in that it enables two-way communication between the meter and the supplier. Advanced Metering Infrastructure (AMI) differs from Automated Meter Reading (AMR) in that it enables two-way communication between the meter and the supplier. Communications from the meter to the network may be wireless, or via fixed wired connections such as power-line communication (PLC). AMI extends automatic meter reading (AMR) technology by providing two-way meter communications, allowing commands to be sent toward the home for multiple purposes, including time-based pricing information, demand-response actions, or remote service disconnects. Wireless technologies are critical elements of the neighborhood network, aggregating a mesh configuration of up to thousands of meters for back haul to the utility's IT headquarters. Consumers can use the information provided by the system to change their normal consumption patterns to take advantage of lower prices. Pricing can be used to curb the growth of peak demand consumption. AMI differs from traditional automatic meter reading (AMR) in that it enables two-way communications with the meter. The electricity meter then aggregates this data and transmits it to the central utility network via Power Line Communication (PLC), which leverages existing electrical wiring for data transfer. Smart meter communication protocols are essential for enabling reliable, efficient, and secure data exchange between meters, utilities, and other components of advanced metering infrastructure (AMI).
