in CA, it's essentially required at this point to pick a TOU plan. It may be possible to drag it a bit, but ultimately you get to chose. Unfortunately, the peak and off peak rates are both high compared to what we had just a decade ago when we still had 4 tiers, with the base tier (60% of average use by a miser) being 12 or 13 cents, and then it shooting up into the upper 20s. In that period, it was ideal to have enough solar to keep you out of tiers 3 and 4. Then it collapsed to 2 tiers both in the 20ths, single rate, and now our TOU.we have no TOU. Apparently there was in the past but PSE&G ditched it although rumor has it that there are a few grandfathered.
We pay a tiered rate based on usage that ranges from about .175 to 195. It's tricky to figure out. Although the kw only has about 4 tiers in my typical month, the service/delivery is also tiered and they don't overlap so you have to multiple those to get between 6 - 10 tiers.
TOU wouldn't help me anyway as I"m retired and I'm pretty sure that my summer daytime AC use would kill any savings. But if they bring it back, I'll of course check it out.
TOU is either 4-9pm every day, or 5-8 on weekdays. I took the latter as I moved to solar. There is also a couple EV rate plans, but not advantage for me over the existing rate metering, and not enough incentive that I see to do middle of the night charging schedules.
Weirdly, the grid friendliest time for me to charge is 10am-3pm, esp in the spring when solar generation has to be curtailed due to excess.
