The Smart Grid requires a two way communications network to enable AMI (Advanced Metering Infrastructure) and other applications to the meter and beyond. While AMI as a stand alone application may not require a broadband connection, it is not desirable to select a communications network based on AMI alone. For a forward looking utility that plans on deploying additional smart grid applications in the future, selecting a narrowband network that is vertically integrated with its AMI product is quite limiting. Furthermore, selecting a proprietary communications protocol that locks the utility customer to a specific vendor is another potential trap to avoid. A Smart Grid communications network should be able to support multiple applications concurrently and should be based on an open standard architecture for interoperability with future products and software applications. The DOE stated that the Smart Grid communications network should be able to support applications from the point of generation to the point of consumption of energy. This implies a horizontal communications layer rather than vertically integrated solutions. The DOE strongly recommends open standards and standardization efforts are already under way.

Amperion has been promoting an open IP standard platform that has the capacity to support current AMI and new smart grid applications in the future. Our collaboration with muNet, an AMI and DR vendor, that also supports open IP, provides a complete solution that delivers deep IP to the meter and beyond. As a utility customer you can avoid the AMI trap by making the right selection that will not require a replacement of your meters in the next ten years. The trade off is simply between a short term dead end solution and a long term future proof alternative. Selecting an open architecture that is based on proven standards is a future proof decision.
