Smart Meter

Smart electrical meters, also known as interval meters or time-of-use meters, replace standard meters and provide more detailed information on electricity use. Whereas a standard meter records only a running total electricity passing through it, a smart meter records the total electricity flow in each of a series of consecutive intervals of time, such as hours. Typically smart meters report metering information to the local utility where it is stored on a computer.

Smart meters enable time-of-use and real-time metering, which allow charges and credits for electricity consumption and production to be pegged to the time-varying value of the electricity.
