Significant Inaccuracies Discovered in Smart Meters
By Joyce Deuley
Last week, I wrote an article for IoT For All about a recent study on smart meters that came up with troubling results.
The University of Twente (UT) and the Amsterdam University of Applied Sciences (AUSA) found that 7 out of 9 energy meters that were tested showed significant inaccuracies–some as high as nearly 6 times the actual amount of energy consumed, and some as low as 30% below the actual amount. (Read the full article here: Significant Inaccuracies Detected in Smart Meters).
The researchers found that this was due to specific hardware components within these meters not being able to detect erratic wave forms of energy in energy efficient appliances. In order to correct this, it is likely that those meters will need to be physically replaced. And, as of now, no one is certain who is going to bear the brunt of the cost to fix them.
Roughly 750,000+ Dutch households could be negatively affected by inaccurate smart meters; so what does that mean for the rest of the world?
As more countries are rolling out smart meters over the next few years, it is imperative that we consider not just the benefits of rolling out these type of deployments, but ensure that we actually have the technology in place to achieve those benefits.
