...so, regarding Puerto Rico, he also said one of the two lines was being used for training and was probably not going at full speed.I really want to believe the guy and the numbers you summarize here. But he also said 4 lines were online last year which should have been 9GWh over 2017. Yet there were not enough cells to go around for the Australian project?
Last year I would expect that none of the lines would have been going at full speed.
He also said last year that the car battery cell chemistry and Powerpack battery cell chemistry are different, and that they had ended up with a giant stockpile of car battery cells simultaneous with a shortage of Powerpack cells due to the Model 3 module assembly problem. A misallocation of the 4 lines between cars and Powerpacks.
:shrug: the information is all third-hand from leaks, so the "game of telephone" applies. He could be off by a factor of 10! More likely, there are bottlenecks and shutdowns for cleaning or maintenance which he didn't mention/know about, and this is "optimal" production speed which cannot be generalized to a full year.
But it all sounds plausible enough. 45 GWh is within the ballpark of the originally planned 35 GWh; Musk did say he'd managed substantial increases in volumetric efficiency over the original factory plans; and this is just the cell lines (meaning, I'm not sure they have the same capacity on the module lines or on the aging chambers or on some of the earlier chemical processes, and they may need to finish the building to get this capacity on the full process).
