The Need For PI

• Duke Energy generates a significant amount of “real-time” (time-series) data in its daily operations.

• Data is used for numerous work activities throughout the generation, transmission, and distribution work processes.

• Examples:Plant OperationsEquipment TroubleshootingPlant Thermal Performance CalculationsDistribution Load MonitoringElectric Grid Load MonitoringLake Level Monitoring


The Need For PI

• Sources of data:• Transmission’s Energy Management System (EMS)• Plant Distributed Control Systems (DCS)• Distribution Automation Equipment• Automated Meters• Manual Input

• Data Is produced 24 X 7.

• Currently collecting data on hundreds of thousands of data points.

• Availability of data provides opportunity to enhance and automate business process activities.
