This change saves the grid operator money, does nothing for you
Water heaters “store” grid power for use later

My guess is your water heater is both big and weak at the same time.

AKA It can eventually get your water hot but has too low of BTUs to maintain a temperature during use

Very possible it might even be off when you are using it.

I would insulate it if you can, it doesn’t save a lot of power but on electricity with it turning on and off randomly it might make things more pleasant and electricity is very expensive so even a small savings is several dollars.
If you can turn it up a few degrees (and insulate) you might have a more pleasant shower.

If you want to “save money” you need a power assisted shower head to reduce water use, insulate the tank better (especially the head), increase temp to make up for the reduction of water through your shower, if your shower takes a long time to get warm insulate pipes and add a recirc valve or inline heater and there are cellular control devices that can keep your water heater completely off during times you never use it, just make sure those times aren’t when the utility wants it on.

In areas that need AC the most interesting are heat pumps that heat water and give you ac

Unfortunate we don’t try to recover the heat from your “waste” water as well which could cut your bill in half
