Belated update from Tuesday, 3/16:
1. As I arrived, the pedestals were being wrapped in clear plastic (presumably pallet wrap), which I think implies that they're installed but not going to be useable soon. (Tesla's map site says Q2.)
2. No PG&E transformer yet, and they were digging a deep hole between an existing underground vault and the concrete pad for the transformer. After I took a picture, the backhoe operator said no pictures.
3. Tesla's white cabinets are hidden inside an enclosure, apparently similar to the Windsor (California) location.
