I don't think that is the case, unless you work for the marketing department of an electricity supplier.
Domestic smart meters have one purpose: to increase revenue for utility providers with a very small investment. No need to upgrade generation, transmission or distribution capacities at great cost, just cahnge the meter and start cashing in. The largest investment is not the meters themselves. No, the biggest cost is the marketing barrage required to convince captive consumers that they are part of some environmental crusade.
Most people use energy during peak hours because they must. They come home from work, cook dinner, do laundry, read to the kids and go to bed. Repeat for 60 years, die. Nobody is going to get up at 3 AM to make toast and have a shower.
Regarding utility costs in Alberta: what the graphs above do not show is contract costs for Hydro. I pay Enmax $.08 per kwh and that rate is guaranteed for five years. I can opt out of the deal with one months notice to Enmax if the regulated rate drops as it floats up and down. There are no demand charges or time-of-use fees so far for domestic users. Industruil customers have had both for many years .
