TOPIC: Xcel EVSE Pilot Program (They're NOT Chargers!)
I've come across some interesting information re public EVSE stations ("Charging Stations") in the Xcel energy service area.
=====
The short version:
In MN, Xcel is starting a pilot program of public charging stations with roughly 75 to 80 different locations, generally (but perhaps not completely) concentrated in the Twin Cities area (Minneapolis & St. Paul metro area in Minnesota).
MOST, but likely not all, of these locations have 4 stations with 60 amp breakers. The model of EVSE ("Charger") is not known at this time.
=====
The slightly Longer version:
The typical installation starts at a wood pole, with a pair of paralleled cable sets come down the pole. Apparently 4/0 for the pair of hot conductors and 2/0 for the neutral, paralleled for six total conductors in two pipes. The paralleled hots feed a Milbank cabinet with a meter and a 400 Amp main, which in turn feed four 60 Amp circuit breakers. These four breakers feed two conduits that pass their conductors to TWO pads, each of which will have two "Chargers" (EVSEs!), for a total of four "Chargers" ("EVSEs!") per location.
Note that the 75-80 number does not include a number of school bus garages and their associated EVSEs ("Chargers"). Some have been finished, more have not. Quantities uncertain, possibly 3 to 12 locations (for now); this information uncertain.
Unknown how many "chargers" per location is typical.
Also unknown is how many electric school buses have been purchased per location.

If you find out more information, please share it.
There is very little information available at the PUC (Public Utilities Commission) web site. Apparently Xcel asked the PUC for permission to do the pilot program, and were told to skip the paperwork, and just "go forth and..." try out their ideas.
To see what little there is (on THIS topic), go to the MN DOC Efiling (state.mn.us) web site:
https://www.edockets.state.mn.us/EF...eDocketsSearch&searchType=new&userType=public
...Then select "20" under the drop down menu, and in the box to its right, type in "745". You're trying to get to a list of documents all under the "20-745" docket number. As of this writing, the list is 82 documents long.
Note that while Xcel may be uncomfortable with any of the above information getting out, I have not heard that it is secret or confidential information.

{Note for non-Minnesotans: Before a merger, Xcel was better known as NSP, 'Northern States Power'. It may not be the largest electrical utility in Minnesota by area, but it's likely second. It is the largest by population and presumably by kW capacity. Utilities in WI, ND, SD, CO NM & TX share the same parent company.}
