Once a green transformer is sitting on that concrete transformer vault, instead of the wooden board covering the slot, you can start getting your hopes up. But after it's delivered, the utility will still need to connect it, which occasionally means a scheduled/announced interruption of the neighborhood power supply, depending on the local infrastructure. Then Tesla will need to get their tech up there to certify and activate it. That final step took over a week for our nearest SC this month, at least in part because of the increased rate of site completions this month. I hope your mother's heart will recover from the disappointment!
