A Review on Smart Energy Meters and Their Market Trends

The power system is progressing toward the Smart Grid paradigm,because of new technologies and communication protocols. Both customers and utilities would profit greatly from this infrastructure update, particularly because bilateral end-to-end interaction between smart meters and utilities can allow for better resource management and operational cost reduction.This paper explains the evolution of smart meters, from manual meters to automated meters and finally to Advanced metering infrastructure (AMI).Different smart grid projects are undergoing in ten different states of India detailed under domestic smart meter market scenario. Whereas, it is seen under Global market scenario of Smart electricity meters that Compound annual growth rate (CAGR)would increasebeyondits estimated worth i.e., US${\$}$ IO.5 Billion in 2020 to US${\$}$ 15.2 billion by 2026. Market trends of various major companies manufacturing, and selling smart energy meters are provided, and a comparison is made between them in terms of display type, meter type, minimummaximum temperature range, minimum-maximum measurement range, prices etc.
