We’re beginning, indirectly, to get a view of the volumes of data that smart energy systems may generate or consume. Already, even the data requirements of the functionally simple smart metering programme in the UK appear to be massive. There may well be an awful lot of smart energy data around.Some people talk a lot about an ‘information explosion’, and this might sound like one, but I’m not so sure. There are certainly a lot of ones and noughts being generated. But information is what they perhaps aren’t.
