Explore the smart electricity meter market for residential, commercial, and industrial use. Learn about net metering, remote connect/disconnect, and the end of estimated bills.
The humble electricity meter has become a sophisticated data node. The smart electricity meter market provides devices that measure consumption in intervals and communicate that data to the utility. This eliminates the need for manual meter reading, enables accurate bills, and provides customers with detailed usage information. As utilities seek to reduce operational costs and improve grid reliability, the smart electricity meter market is growing, with hundreds of millions of units already deployed globally.
The broader smart meters market includes this segment. A key feature of smart electricity meters is "net metering." For customers with rooftop solar, the meter can measure both the electricity drawn from the grid and the excess solar electricity exported to the grid. The smart electricity meter market for "bidirectional" metering is essential for solar adoption. The smart electricity meter market also includes "time-of-use" (TOU) rates, where the meter records consumption in different time bins (peak, off-peak, shoulder), allowing the utility to charge higher rates during peak demand.
The smart electricity meter market also enables "remote connect/disconnect." A utility can remotely disconnect a delinquent customer's meter (or reconnect after payment) without sending a technician. The smart electricity meter market for "load limiting" allows the utility to reduce the maximum current available to a customer (e.g., to 5 amps) rather than cutting power entirely, which is useful for bill payment problems. The smart electricity meter market also includes "outage detection" and "restoration verification." When a meter loses power, it sends a "last gasp" message; when power is restored, it sends a "restoration" message.
The smart electricity meter market is segmented by communication technology. The smart electricity meter market for "RF mesh" (using the 900 MHz or 2.4 GHz band) is dominant in North America and Europe. Meters communicate with each other and with data collectors mounted on utility poles. The smart electricity meter market for "cellular" (using 4G/5G) is used in rural areas and for "secondary" meters (e.g., at a remote well). The smart electricity meter market for "powerline carrier" (PLC) sends data over the existing power lines; it is common in Europe (e.g., the PRIME or G3-PLC standards).
The smart electricity meter market also includes "safety" features. Smart meters can detect voltage anomalies (e.g., loss of neutral) and alert the utility, preventing appliance damage. The smart electricity meter market for "tamper detection" (e.g., detection of magnetic field or removal of meter cover) reduces energy theft. The smart electricity meter market for "non-intrusive load monitoring" (NILM) uses algorithms to disaggregate total usage into individual appliances (e.g., AC, refrigerator, dryer) without additional sensors.
Looking ahead, the smart electricity meter market will see the integration of "EV charging" management. The meter can communicate with the EV charger to optimize charging based on grid conditions. The smart electricity meter market will also see the adoption of "universal" communication standards (e.g., DLMS/COSEM, ANSI C12.19) to ensure interoperability. As the grid evolves toward a "grid of things," the smart electricity meter market will be the edge device that empowers both utilities and customers.
