Some people are reporting on social media that their electricity bills are doubling after the installation of smart meters:
This blog explains the problem:
Simply speaking, when any domestic electrical appliance is switched on, it momentarily draws heavily on the electricity supply. The key words to remember here are ‘surge voltages’. These surges at switch on can be several times the electrical rating of an appliance, and the bigger (and older) the appliance, the larger the surge. With the old meters this wasn’t an issue, as these surges are so short that the old electromechanical meters couldn’t record them. However, the ‘Smart meters’ being purely electronic, record every last milliamp, and report these directly to the suppliers via a mesh type network on a real time basis. Never mind being billed at varying rates for different times of the day.
Essentially what happens is that if you have a family that uses dishwashers two or three times daily, or cooks with electricity using an electric oven twice a day, and has gotten used to washing their clothes regularly, then your bills will soar, especially if you cannot afford to replace all your older appliances whose surge voltages are likely to be significantly higher than more electricity efficient modern equipment.
Does this sort of meter behavior significantly increase electricity bills?
