I do not quite follow, why does TSLA need another factory in Nevada. Unless I am mistaken, they got one in Sparks and that facility is not finished and not exactly fully utilized either (a “gigafactory” which produces less then 35 GWh?). Another one in Fremont, which is occupied, but production of S and X is probably done.

I guess, Tesla will get tax payers money for new site, which would not be available  should they just refurbish Sparks or Fremont facility.

Maybe the new battery factory will make pouched cells but more likely solid state cells.  Completely different from the existing cylindrical cells.  Then the new cells would be for new car models while the old models still use the cylindrical cells.  Just a thought....
