Monitoring power plant performance in real-time is essential to stay competitive in the market-based bulk electric system. Maintaining equipment reliability with dwindling resources and regulatory and environmental compliance are some of the challenges electric utilities face today. DTE Energy has been addressing these challenges with effective use of technology turning data in to actionable information. Using its ‘Technology Framework’ as a roadmap, DTE Energy has implemented several layers of technologies with PI System data as their backbone. The amalgamation of people, processes and systems at the fleet-wide monitoring center using real-time operational data, predictive monitoring and market interface is helping DTE Energy to meet these challenges. DTE has embraced the recent partnership of OSIsoft and GIS (geographical information system) leader ESRI – a relationships that brings out of the box integration between the PI System and ArcGIS, enabling a platform for real-time GIS as well as seamless back-office integration between operational data management and GIS. As a lighthouse account, DTE has integrated both products to deliver a fault indication application for system monitoring.
