Smart meters are responsible for the collection, measurement, transmission and processing of electric energy data and are an important part of smart grid construction.
According to analysis by the Industrial Research Institute, China’s smart meters are expected to see a demand inflection point in 2025. As the demand for power informatization and new energy continues to expand, the demand for smart meters is expected to continue to grow from 2026 to 2028. Digitalization and intelligence are the main development directions of smart meters. The construction of the Internet of Things has played a role in promoting the demand for smart meters.
Looking globally, the smart meter market size is expected to grow from 162 million units in 2024 to 236 million units in 2029, with a compound annual growth rate of 7.81%. The global smart meter market is approximately US$12.6 billion and is expected to reach US$16 billion by 2027.
With the market demand trend and the policy support and promotion of various governments.
The global smart meter market will continue to maintain a high level of prosperity. Developed countries such as Europe and the United States and some emerging countries such as China have entered the meter replacement cycle, and the demand for smart meters has grown.
