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.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.
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.
