I think it's pretty common to have 13.8kV available to a business
location. Usually a step-down transformer is provided at site but in
this case, they may want to use 13.8kV directly.
The other factor which could make a huge difference is load leveling
using a large battery. That would help as long as there's a modest
amount of time between charges.

Really? I'm far from an expert on electric utility issues, but 400kW
is
about the total peak capacity of 4 recently built bloated McMansions
(main
panel == 400 amps at 240 volts). I don't see a substation for every 4
houses in those neighborhoods, but maybe I'm missing something. And
of
course those houses aren't all running at peak load all the time,
either.
