As reported by web site Boing Boing, a research team from the University of Twente in Enschende, Netherlands, and Amsterdam University of Applied Sciences documented billing inaccuracies in a paper that reviewed the efficacy of so-called “smart” electric meters, ranging from -32 percent to +582 percent of the actual power consumed in a month’s period.
The paper also noted that, ironically, the overbilling is mostly due to older power-saving features because they introduce line noise that interferes with the wireless signal and thereby ‘confuses’ the meters. (RELATED: Read SILENT KILLER: Smart Meters Are Destroying Your Health.)
“Static, or electronic, energy meters are replacing the conventional electromechanical meters. Consumers are sometimes complaining about higher energy readings and billing after the change to a static meter, but there is not a clear common or root cause at present,” an abstract of the findings states. “Electromagnetic interference has been observed between active infeed converters as used in photo-voltaic systems and static meters. Reducing the interference levels eliminated inaccurate reading in static meters.”
In all, five of nine smart meters that were tested provided readings that were substantially greater than the real amount of energy utilized, while two actually gave readings lower than the amount of power consumed.
