Supercharger - Upland, CA (under construction Jan 2024, 64 V3 stalls)

Paving is completed and most of the fencing has been taken down. No transformers on site. Let’s see how long SCE takes to deliver the two transformers needed.

I live in Claremont. This is great. Where are the vaults for the 2 transformers in the pictures ?
Large, need 8 MW each. Does that mean transformers don’t show above ground level ?

A favorable reason for this location is that there is a high voltage spur line that feeds a sub station just to the west on Pomona College campus and it supplies all Claremont College campuses. That HV line should have plenty of capacity for this SC installation.

The vaults are centered between each set of 8 cabinets. During construction it looked like they dug out for underground transformers.

Looks like they are pretty much complete on the DC bus wiring. Parking lot striping and transformers may be all needed.

Each v3 cabinet, supplying 4 charging posts, draws around 350kVA from the grid.
So the overall site should need something like 2 x 2800kVA.

They may end up getting two 4000amp 480V feeds from SCE, which would come from the 12kV distribution network.

The 66kV line feeding claremont colleges private substation is certainly a lot of capacity, but probably not something they would end up using.

I stopped by yesterday to take these pictures.
