Installations of intelligent meters have some-more than doubled given 2010—almost half of all U.S. electricity patron accounts now have intelligent meters. By a finish of 2016, U.S. electric utilities had commissioned about 71 million modernized metering infrastructure (AMI) intelligent meters, covering 47% of a 150 million electricity business in a United States.
Smart meters have two-way communication capability between electric utilities and customers. One-way meter-to-utility communication, also famous as programmed scale reading (AMR), was some-more prevalent before 2013. Since then, two-way AMI intelligent scale installations have been some-more common formed on information collected in EIA’s annual electric application surveys.
Two-way AMI meters concede utilities and business to correlate to support intelligent expenditure applications regulating real-time or nearby real-time electricity data. Smart meters can support direct response and distributed generation, urge reliability, and yield information that consumers can use to save income by handling their use of electricity.
AMI information yield utilities with minute outage information in a eventuality of a charge or other complement disruption, assisting utilities revive use to business some-more fast and shortening a altogether length of electric complement outages.
Residential intelligent scale invasion rates change widely by state. Washington, DC, has a top AMI invasion rate during 97%, followed by Nevada during 96%. Six other states had a residential AMI invasion rate aloft than 80% in 2016: Maine, Georgia, Michigan, Oklahoma, California, and Vermont. In 2016, Texas combined a many residential AMI meters of any state, installing intelligent meters on some-more than 200,000 patron accounts.
Differences in intelligent scale invasion rates are mostly driven by state legislation and regulation, as some states need that regulators approve utilities’ cost liberation mechanisms for metering projects. The Smart Electric Power Alliance publishes reports on state-level actions on modernized metering, among other topics.
Many residential business might not be wakeful that they have a intelligent meter. EIA final conducted the Residential Energy Consumption Survey (RECS) in 2015, a year when residential intelligent scale adoption was about 44% nationwide. In that year, 22% of households reported carrying a intelligent meter, 49% reported not carrying one, and 29% responded that they did not know. Only 8% of households reported being wakeful that they had entrance to hourly or daily data, and only 4% pronounced they had accessed or noticed that data.
