You have confirmed my estimates.Yeah TOU-B and TOU-C wouldn't be so bad... assuming you were able to size your solar to cover your EV charging as well. Because then you could just use the NEM with TOU-B/C and you wouldn't need the "discounted" off-peak charging period under EV2-A.
But this EV2-A rate is just insane for all your other normal home consumption. I can't imagine how people live with this EV2-A thing. Solar generation is a fraction of what you'd see under TOU-C, but the costs during peak time are like 2x higher.
We stayed on TOU-B even though we have 2 Teslas because we have been working from home for 5+ years and will likely stay that way. So we only need to charge a car every other week.
