Does anyone understand what the delay is?
These chargers have been ready but wrapped in white plastic for several months. You can see them from the W&OD and it looks like everything is there for a functioning Supercharger site. (There is a rumor that bureaucrats at Fairfax County are slow walking permits for EV chargers.)
There is no utility transformer, as shown in the pictures above. There is a national backorder on utility transformers, so it can take weeks or months to get that final piece in place.
