Driven to further increase energy and operational efficiencies and encouraged by government policies and incentives, many utilities are exploring, planning, or already beginning to implement “Smart Grid”. Smart Grid implementations can potentially add hundreds of thousands, if not millions, of new equipment and devices to the energy delivery system and infrastructure of the utility. Measurements will be collected from Smart Grid sensors and metering devices at hourly or 15-minute intervals, and some in near real-time, resulting in terabytes of data. Utility commands and controls will be available down to the customer-premise level. How would the utility manage all these new assets, all the new data, and the new advanced functionality to achieve the vision and objectives of Smart Grid? This presentation outlines the transformational changes of Smart Grid to the utility enterprise and through utility case examples, how the utility should prepare itself for these changes through Enterprise Information Management.
