Okay, time to rain on this happy parade.
The level 3 build out is not sustainable, mainly due to peak demand power charges. Private businesses are not going to adopt building the infrastructure when they literally could lose money if too many folks are drawing 150 kW or more. That issue needs to be fixed; I have no idea how to do that, however. And to fill in all the gaps, it must be driven by the private sector.
Okay, tell me why I'm wrong. (I want to be wrong, but I know someone who just put in a level 3 in Brookings, SD, paid with VW settlement money (ie would not have happened otherwise) who told me even though his charger can do super high speeds, he maxed it at 62.5 kW due to demand charge issues. The NEVI plan for SD also pointed out demand charges being the biggest problem for sustainability and even getting bids.)
