Advanced metering infrastructure[edit]

Overview[edit]

Example of a smart meter based on Open smart grid protocol (OSGP) in use in Europe that has the ability to reduce load, disconnect-reconnect remotely, and interface to gas and water meters.
Newer retrofitted U.S. domestic digital electricity meter Elster REX[1] with 900MHz[2]mesh network topology for automatic meter reading and "EnergyAxis" time-of-use metering.[3][4][5].
Each local mesh networked smart meter has a hub such as this Elster A3 Type A30, which interfaces 900MHz smart meters to the metering automation server via a landline.[6].
Itron OpenWay electricity Smart meter with two-way communications for remote reading in use by DTE Energy.
A smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.
Smart meters communicate the information to the consumer for greater clarity of consumption behavior, and electricity suppliers for system monitoring and customer billing.
Smart meters typically record energy near real-time, and report regularly, short intervals throughout the day.[7] Smart meters enable two-way communication between the meter and the central system.
Such an advanced metering infrastructure (AMI) differs from automatic meter reading (AMR) in that it enables two-way communication between the meter and the supplier.
Communications from the meter to the network may be wireless, or via fixed wired connections such as power line carrier (PLC).
Wireless communication options in common use include cellular communications, Wi-Fi (readily available), wireless ad hoc networks over Wi-Fi, wireless mesh networks, low power long-range wireless (LoRa), Wize (high radio penetration rate, open, using the frequency 169 MHz) ZigBee (low power, low data rate wireless), and Wi-SUN (Smart Utility Networks).

Technology[edit]

References[edit]

The term Smart Meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption.

Brief history[edit]

Similar meters, usually referred to as interval or time-of-use meters, have existed for years, but "Smart Meters" usually involve real-time or near real-time sensors, power outage notification, and power quality monitoring.

These additional features are more than simple automated meter reading (AMR).

Purpose[edit]

Opposition and concerns[edit]

  • They are similar in many respects to Advanced Metering Infrastructure (AMI) meters.
  • Interval and time-of-use meters historically have been installed to measure commercial and industrial customers, but may not have automatic reading.[citation needed].
  • Research[which?] by the UK consumer group, showed that as many as one in three confuse smart meters with energy monitors, also known as in-home display monitors.[8].
  • The installed base of smart meters in Europe at the end of 2008 was about 39 million units, according to analyst firm Berg Insight.[9] Globally, Pike Research found that smart meter shipments were 17.4 million units for the first quarter of 2011.[10] Visiongain determined that the value of the global smart meter market would reach US$7 billion in 2012.[11].
  • As of January 2018, over 99 million electricity meters were deployed across the European Union, with an estimated 24 million more to be installed by the end of 2020.
  • The European Commission DG Energy estimates the 2020 installed base to have required €18.8 billion in investment, growing to €40.7 billion by 2030, with a total deployment of 266 million smart meters.[12].
  • By the end of 2018, the U.S.

  • had over 86 million smart meters installed.[13] In 2017, there were 665 million smart meters installed globally.[14] Revenue generation is expected to grow from $12.8 billion in 2017 to $20 billion by 2022.[15].
  • Smart meters may be part of a smart grid, but do not themselves constitute a smart grid.[16].
  • In 1972, Theodore Paraskevakos, while working with Boeing in Huntsville, Alabama, developed a sensor monitoring system that used digital transmission for security, fire, and medical alarm systems as well as meter reading capabilities.
  • This technology was a spin-off from the automatic telephone line identification system, now known as Caller ID.
  • In 1974, Paraskevakos was awarded a U.S.
  • patent for this technology.[17] In 1977, he launched Metretek, Inc.,[18] which developed and produced the first smart meters.[19] Since this system was developed pre-Internet, Metretek utilized the IBM series 1 mini-computer.
  • For this approach, Paraskevakos and Metretek were awarded multiple patents.[20].
