It’s not even a program. these potential roadblocks, Capgemini Though it might be launched as such, will describe the five critical “behind it quickly evolves into something far the scenes” issues that utilities will greater. It is, in fact, a transformation. inevitably face in deploying a Smart Grid: GIS Data and Processes, As utility companies across the Existing WAN/LAN Networks, world are increasingly discovering, Energy Delivery Network Topology, the deployment of a Smart Grid Integration Architecture, and fundamentally changes the way they Legacy IT Systems. Based on our generate data, present information, experience in collaborating with make decisions, execute work and leading utilities on successful Smart relate with their customers. For this Grid deployments around the world, reason, it is important to ensure that the this document provides our insights foundation of your Smart Grid is solid. and recommendations for building a strong Smart Grid foundation. Many, if not all, of the foundational elements are already in place at most utilities. However, getting them to meet the new requirements that Smart Grid creates will present significant challenges to those responsible for deploying and operating them.2
