In TX, the power producers, distributors, and retail electric utilities are (most commonly) different parties, so the latter two are very much interested in the type of decentralized time-shifting you mention since it smooths wholesale costs somewhat and reduces grid buildout and maintenance.

For EV owners in TX, its not uncommon to have fairly free charging overnight (just paying the distribution costs of 5-6 cents/kWh).

For homes with residential solar and batteries in addition to the EV, you can have essentially free power and EV charging due to time-shifting and incentives.

Residential batteries are still quite expensive, though, so it would be amazing to recruit those in the above EV to time-shift using V2H.
