Electrify America Fast Chargers - Huh?

By no means an expert, I'm under the impression that even 4 stall EA locations have two 350 kW and two 150 kW, for a total of 1 MW power.
Nope. Even the 4) 350kW stall EA sites normally only have a ~750kW transformer. They are paired stalls, where 350kW is shared between two stalls. (They called it "balanced".) They don't have a dedicated 350kW available per 350kW stall.

But that specific point was about EA only having a lease for 4 parking spots, and Tesla would likely want to put in a minimum of 8 stalls, so would need a new lease anyhow.

That would trigger the requirements for new building permits, planning board approvals etc.

Most 8-stall V3 around my area are serviced by 750kva transformers.
Former electric company employee DFW here. We typically load transformers to 130% nameplate in the summer and 160% winter. Besides, the transformer is really heavy and so takes a long time to heat up. Since EV's only use the max charge power for ~10 minutes or so, it's not a big deal. We also used readings from the meters connected to the transformer to be able to tell when the transformer is overloaded.

Most 4-stall EA I've been at are 150 350 350 150. But Kittery, ME is 4 x 150. (I was charging at #2 in Kittery, and offered to swap with a waiting EV6 when #4 became available, but then realized it was all 150). 4 stalls, 8 cables no power sharing is so frustrating.
