I think there are a lot of these site surveys that may end up not being final locations. Some definitely do but some do not. Since they are just a survey.
Searching for the CPA contact, there are 7 site surveys in Newark, DE since March 1. Only 1 actually lists Tesla but others reference some of Tesla's real estate partners like Kimco and Kimley-Horn. Will be interesting to see which of these sites end up being the site.
There are also surveys being done for Bohler engineering which has been involved with SC installations at Wawas.
