Digital energy meters may give false readings
2017-03-14 | By ACCESS
In the Netherlands, traditional energy meters are gradually being replaced by digital ones, usually called “smart meter”(slimme meter). Over the past few years, consumers complained about higher energy readings and bills after the meter has been changed.
Energy suppliers can read these meters from a distance. Research at Twente University shows that about 850,000 meters out of approximately 3 million installed smart meters may give false readings. During tests, the differences even reached 582%. However, this doesn’t mean that your annual use can be 6 times higher. Some meters can – under specified circumstances- measure the use of some equipment up to 6 times higher. But nobody uses only the equipment that could cause this problem.
According to network company Liander , the problem centres on meters installed between 2012 and 2014. Large companies are the most likely to be affected . Households with solar panels, electric cars, led lights with dimmers or energy-saving light bulbs with dimmers may experience false readings as well.
According to RTL News, the meters that can give false readings are:

Should you experience extra high readings on your ‘smart’ energy meter, it is best to contact your energy supplier.
Consumer organisation Consumentenbond, suggests conducting research about this problem. All parties involved should take this seriously, solve the problems and maybe some meters should be replaced.
