And every hour another 960,000 sets of meter data have to be processed.” If we have 240,000 smart meters getting readings every 15 min, we will have 960,000 sets of data per hour. Let's say, a smart meter sends 3 values every 15 minutes. One for the time, one for the energy and/or power and one for the frequency, or anything related. Let's assume every value needs 8 bytes (big enough) in order to be stored. In that case, the utility enterprise would have to analyse: 960,000 * 10 * 10 bytes =~ 22 Megabytes of data per hour This is big data? Please explain. “For a large to medium sized German utility, which has about 240,000 conventional meters, quarter-hour meter readings would produce 960,000 sets of meter data to be processed and stored each hour once replaced by smart meters.
