Smart Grid 101: Terminology Overview

Recently the media has been abuzz with hype surrounding the creation of a “smart grid.” As with most technological advancements, the advent of the smart grid has brought with it a host of new acronyms and terminologies. We thought it might be helpful to identify and define several key terms:

Automated Meter Reading (AMR): Meters transmit data via wireless radio frequency to a data collection device; readings must be gathered within a limited range of the meter; one-way communication from meter to a data collection device.

Advanced Meter Infrastructure (AMI): Utilizes advanced technology to create a communication network between a utility and its meters; two-way communications between utility and meters. The meters we will deploy communicate by relaying information wirelessly from one meter to the next. This allows for real-time data collection, asset monitoring and asset control; forms basis for smart grid.

Time of Use Rates: This describes a new rate structure being implemented by the TVA wherein electricity rates will vary according to its relative cost during a given time of day. This will resemble the cell phone rate structure many of us have come to know which allows for reduced rates on calls made during “off-peak” hours.

Stay connected at where we will offer additional educational resources as we move forward on the deployment of our new smart grid.
