Some of those areas don't have variable electric tariffs that promote use of electricity when the electric company wants you to use the electric. Here in central NC, most residential customers just have one electrical rate - whatever the electric company wants to charge, and there's no competition. However because the electric infrastructure around here was built around supplying lots of electric power to the textile mills and they have now been shut down, the power companies have excess capacity here. Datacenters are coming here to fill the void somewhat, but not in terms of raw number of employed people. But when it comes to electric vehicles the interim solution is for electric companies to offer an "electric vehicle" tariff on a circuit that is controlled by the electric company - and to encourage EV users to charge at times convenient to the electric company. However these charging stations should IMO make use of a dual circuit - giving EV owners the option to give their vehicle a charge boost at peak power pricing, whilst giving the same option of garaging the vehicle overnight to charge when the electric company thinks it can send power to that charging station.
