Looks that way in the overhead drone videos we've been getting as well.
It also looks like there's a nice big field growing stuff right over the canal / river along one border. Like maybe they could double up the land under Tesla car cultivation if they can find a mutually agreeable price for that land.
Of course, probably the smart / diversified / resilient thing to do is to get a new site at another location in china for the next site. How long do they wait before the expansion of Giga Shanghai turns into site prep at a new China site? H'mm...
What I find quite amazing is that 1 year ago Tesla was battery constrained with Pana struggling to lift output. Now Tesla has seems to have relatively easily achieved supply agreements from LG and CATL that seem to both be able to pump out as many GWh as is desired (combined they may well provide as much output as GF1 by the end of the year) - and these batteries have good enough tech to equal the best in class Pana cells that were so limited last year.
In my finance day job I'm looking at financing a company that needs cell supply in the low GWh range, and they have no problem finding cylindrical cells on the open market to meet this demand (and at a decent price).
The battery cell market appears not to be supply limited at this point in time - although that could rapidly change if EV production takes another few % of the vehicle market.
