Advanced Metering Infrastructure (AMI) is transforming the energy sector by enabling smarter, connected and more efficient utility operations.

Driven by remote metering, secure communications, demand response and smart-grid integration, AMI continues to see strong technological and patent activity worldwide.

Market Outlook

AMI technology activity has grown significantly. Patent filings peaked at 1,016 in 2012, while publication activity reached 904 in 2016. China and the US lead the patent landscape, with major activity from Itron, GE, State Grid, Elster and ABB.

Market Drivers

The landscape is being shaped by automated meter reading, remote meter access, utility–customer communication, demand-response energy management and connected utility infrastructure.

Challenges

Security, interoperability and communication complexity remain key technical considerations. AMI spans RF, cellular, Zigbee, PLC/BPL, Wi-Fi/WiMAX, Ethernet, optical fibre and other communication technologies. Patent ownership and assignment can also complicate competitive analysis.

Innovation

Innovation is moving toward secure, connected and intelligent metering. Key areas include encryption-based communication, 450 MHz spectrum, cellular and wireless communication, TCP/IP-based remote access and utility communication and control systems.

As AMI continues to evolve, innovation in connectivity, security and intelligent energy management will remain central to building the utilities of the future.
