Do smart meters need more energy than our old Ferraris disc meters?
According to a study conducted by Graz University of Technology, if consumer data are submitted in bulks, smart meters consume about five to eight percent less electricity than the devices that are currently used. The meters themselves (leaving communication aside) generally consume less electricity than analog Ferraris disc meters.
But for the most efficient use of the equipment, data should not be submitted one by one. Instead, efficient communication infrastructure needs to be set up so that synergies can be used. In the frequent cases where existing infrastructure (e.g. fibre optic cables) can be used, the additional electricity consumption can barely be detected.
And we must also consider that today’s system, with personally reading five million meters, means consuming a lot of petrol to physically get people to the consumers’ homes. This becomes completely unnecessary with smart meters. If communication infrastructure is rolled out efficiently, the energy consumption of smart metering systems can even be substantially lower than it is at the moment.
