4. Why is Data Volume an Issue? Network capacity is a precious resource for electric utilities because they are – either leasing such networks from third-party providers or – building infrastructure themselves and leasing bandwidth out (especially at the backhaul) to recuperate investment costs Often hear “we have all this data…..” – All the data does not need to go all the way W.

5. Data Stream – An Abstract View 5 Data Generators Communications Network Data Processing/ Storage Need In-Network Data Processing/Analytics - while retaining most of centralized Big Data benefits

6. Benefits Reduce costs to transport, store, and process huge volumes of data centrally Allow targeted granular data collection from some sources while settling for coarser data collection from others – Balance utility needs with customer privacy risks (and any data collection regulations) 6

7. Fundamental Questions What data is absolutely needed by electric utilities and where?, and How can we communicate, store, and process data distributedly for data-intensive, networked applications? 7
