16. 16 MDM is….. The evolution of Load Research Systems created in the 1970’s to serve commercial and industrial customers, wholesale interchange metering, and PURPA. A platform that enables fundamental changes in how utilities operate using vast amounts of measured data and information A centralized data management and data storage platform for existing data and future data collected from AMI systems and new Smart Grid technologies A centralized integration point for integrating utility applications utilizing web-services, Multi-Speak, ODBC, XML, etc. Centralized data analysis and reporting of all operational data A provider of Interval Data Validation, Editing and Estimation (VEE), Meter Read Profiling, Load Research, Energy Settlement, Energy Data Presentation, and Line Loss Analysis A foundation for launching future customer programs including new customer-premise devices (e.g., HAN, Smart Thermostats) 16 © The National Rural Telecommunications Cooperative
