I just looked up that plan and it has a daily fixed charge of $2 per day higher than our current one 😮, and the daytime rates are higher per kWH as well.

Admittedly their main non-EV plan is also super expensive. I would expect that they probably pay Chargenet more than home rates but significantly less than full rates. Genesis charge more in the plan to account for it, and Chargenet get more users feeding into what is effectively fixed costs outside of the power use itself.

The actual chargenet costs are probably covered by the $5/month extra fixed line cost (about a 15c/day difference in their EV and standard plan fixed daily charge for my house). Because most people on the plan are probably there for the 50% night time rate and the cheaper chargenet is likely just a bonus, and outside of some high users the average use is probably pretty low.

50% night rates is interesting. Average wholesale power costs are often something like 3-5c/kWH. We have to pay 25-30c because at certain times of the year it can get to hundreds or occasionally briefly thousands for 1kWH. Plus the whole thing above about company costs. But night time 50% off probably doesn't actually cost that much for them considering their huge daily charge, which I'm still flabbergasted by😆.
