Smart meters are sold- state contric devices that measure electricity consumption wigh high granularity, typically at 15- minute or hourly intervals. Unlike traditional electromechanical meters that only contrid total cumulative usage, smart meters capture time-of- use data and communicate it via wireless or powerline carrier networks to a central -end system. This data enabled precise billing, did responses programs, and realreald -time grid visibility.
