On an average day: we use approximately 12 kw. On laundry days we use roughly 20kw. What is interesting on non-laundry days, you can tell when the coffee maker was turned on or the tv or any other appliance. The graph on those days measures in 0.2 kilowatts on the hourly chart. On laundry days it measures in killowatts.
They are a good idea because we should get bills from accurate readings instead of estimates, it should stop people bypassing the main supply for criminal use, downside is that people no longer need to read the meters which could lead to job losses.
