We have a solar electric plan - the price per kWh is much higher during the duck curve in return for cheap rates during sunshine hours. The rates are something like 1x during night, 0.5x during sunshine, 4x during the morning and afternoon peaks.

We have our heat pump water heater running during the cheap hours, and also change our use of air conditioning/heating to accommodate.

It would probably not work in our favor if we didn't work from home and were out of the home all day.

This is already a reality with smart chargers in the UK. Your electric car can be charged when the electricity rates are lower (night usually)

> idk like turning the heat way up during the day

That is something you can reasonably do, but it's only useful in winter.

> or using high power appliances more during the day

Well, given that people have to work during the day, I doubt that that will work out on a large enough scale. And even if you'd pre-program a laundry machine to run at noon, the laundry would sit and get smelly during summer until you'd get home.

The only change in patterns we will see is more base load during the night from EVs trickle-charging as more and more enter the market.
