Yes, I think your observations are right on.
So far I haven't seen this specific wording referenced, (I've probably missed others referencing it), but this, almost throw away comment from Musk during the earnings call, seems to encapsulate what he will be saying in April, and if so, it can't help but move the market:
"So tentatively sort of in the April timeframe, we will do a Battery Day and kind of go through what the challenges are, how do you get from here to, I don't know a couple of thousand gigawatt hours a year or something."
The part that really sticks out to me is the "
I don't know ..... or something"
So casual, like "you know, just a couple thousand GWh a year, no biggy."
We know in the past he has said he wants 2TWh/year by 2030. Now he says that battery day will not just blow people's minds, but it already blows his mind too. Announcing a path to 2TWh capacity by 2030 wouldn't blow my mind. I'm expecting this. And it certainly wouldn't be blowing Elon's mind. So what is? I think it's clear:
We know Maxwell tech is supposed to be 16x production density increase. Let's be conservative and go with 10x. So in the same space GF1 does ~35GWh now, they could do ~350GWh. Now add in similar sized production at the Cell Factories in GF3/4, and we could have ~1TWh/year. As soon as GF4 is up and running
. Not by 2030, by next year.
This would blow my mind. The only limiting factor would be raw material supply.
Do they need this many cells now? Sure they do. Semi will require a huge amount if they want to produce it at any sort of volume. Also, assuming these cells are 20% cheaper, Powerwalls and Megapacks would sell like hot cakes. Fossil fuel peaker plants would be replaced everywhere. Any extra, they would sell to other automakers, they sure need them, and this aligns with Elon's eventual goal.
By 2030, the world will need dozen's if not hundreds of TWh's of capacity. A couple TWh's is nothing. I believe battery day will basically change the course of history. A shot through the heart of ICE and FF. With this level of production capacity, the change to a sustainable future will be immediate.
Or, am I dreaming too big? What else would "blow people's minds"?
Whatever it is, I'm expecting the market to react big in April.
