I notice the plan has a lounge with "keypad and guidance for automated door" - implying 24hr unattended access to lounge and toilets for supercharger users. Are there any other sites with this?
Also two areas on the floorplan marked "battery repair" (with "ESD floor mats" and "rescue pole") implying opening of battery packs. I think we have seen this on other service centre plans, maybe not so much detail. Also interesting is adjacent "battery storage" of two types - one drawn with something looking much like a Model S pack, the other smaller - individual modules???
Utilities statement confirms 1.9MVA electrical supply has already been ordered and paid for. That's somewhat more than needed for the 12 supercharger bays (3 V3 cabinets = 1.16MVA).
Solar PV considered at several places in the various documents (including the "community involvement") but in each case it's dismissed on the basis that using heatpumps for heating is enough to cover the energy-efficiency targets they are aiming for.
