The volume, velocity, and variety of data being created by the power system has dramatically increased. Smart Grid investments have deployed millions of new sensors, meters, and other tools for monitoring the power system. These investments have facilitated better situational awareness across the system, and as a result, improved control strategies for maintaining and improving reliability and flexibility. Better communication and computational systems along with growing use of big-data infrastructure have allowed transmission operators and balancing authorities to provide effective control over larger areas.

To unlock the full potential value of these new data sources, better standards and tools for data processing, analysis, and visualization are needed to help meet the needs of a rapidly evolving energy system. Tools that support real-time decision making need to collect measurements, process them, and display the results to the operator. State estimators and contingency analysis provide suggestions to the operator based on real-time data. These tools take advantage of the increase in available measurement data and improve situational awareness for system operators and planners. This requires dedicated efforts to create data sets, both real and synthetic, for technology development.
