The Smart Grid “Middle Mile” Issues

If the smart grid stalls, it may be because of the “middle mile.” The middle mile may suffer from traffic jams unless utilities plan carefully.

Many utilities start their smart grid push with advanced metering infrastructure (AMI), which doesn’t require much bandwidth or speed. The middle mile starts to get overcrowded when new applications (grid automation, assest management, or outage management) are added.

The solution is to plan ahead for future needs. Utilities need to determine the requirements for bandwidth, for latency, for range and for quality of service (prioritizing critical messages) with a network that has lots of excess capacity or at least has a plan for expanding.
