Standards are emerging that bring the utility industry closer to achieving open, interoperable advanced metering infrastructure (AMI) systems. These standards include lower-layers such as radio and power line carrier (PLC) media and higher layers such as American National Standards Institute (ANSI) C12.19/22 and Device Language Message specification/ COmpanion Specification for Energy Metering (DLMS/COSEM) protocols. Lack of interoperability has been a limiting factor for utilities, generally requiring the selection of a single AMI communication technology provider and locking in to that provider for the life of the system.
Many utilities are interested in interoperability for AMI systems that would allow them to buy meters and other system components from any source and blend them into a cohesive system. At the same time, utilities have recognized that moving to open systems of this sort will bring certain new challenges from both the business and technical perspective. Although such open AMI systems have clear advantages, new challenges may cause some to hesitate as they consider emerging opportunities.
This technical update report examines some of the opportunities and hesitations for a utility to examine when considering implementing an open AMI system, including such issues as responsibility for integration of the system components, which entities provide the required maintenance expertise, and some potential economic effects on the industry.
