As Duke Energy's U.S. infrastructure footprint has expanded, the company has been challenged by its increasingly complex network of substation systems. Legacy infrastructures at Duke limited the availability of data, while constraining scalability and reliability. Key challenges included: Upgrade legacy SCADA systems Scale the substation and corporate networks to support growing number of telemetry devices Meet NERC/CIP, IEC 61850-3, and IEEE 1613 compliance Duke deployed an automated smart grid built on Intelligent Electronic Devices, protection relays, and IP-based systems, all built on Cisco networking equipment. Duke deployed Cisco 2010 Connected Grid Routers and Cisco 2520 Connected Grid Switches as the foundation of an integrated power grid network. The company extended their Cisco infrastructure through their corporate environment and into substations, while implementing centralized security and management platforms.

Duke realized a highly flexible, intelligent foundation for cross-company applications and initiatives. They further improved security and visibility into substation information, while achieving better monitoring and logging of substation telemetry data.
