Utilities today are largely designing smart grid networks to collect data from smart meters in a time frame that ranges from between every 15 minutes to an hour, then bringing that data back to a collection point on the network. From there, many utilities are only bringing data back to the utility back office where the numbers are processed and packaged for consumers once a day. As Google’s Tom Sly explained to me recently, there are two different temporal issues: the resolution of the energy data (at what intervals the energy consumption is tracked) vs. the age of the data (how long it takes before it makes it back to the customer). PG&E, Duke, San Diego Gas & Electric and Southern California Edison are all planning slight variations of this setup.
