In my opinion ....
- Global domestic clients are voting with their wallets for generic Chinese LFP storage. Except for the sort of client for whom the sticker is important, they buy Tesla. Oh, and some Americans. It is already game over for scale-dominance in this segment and Tesla lost the game.
- Global utility clients are cannier. They will never allow anyone to become scale-dominant. The ones who are susceptible to FUD ("no-one got sacked for buying IBM") or who cannot bring themselves to buy Chinese, buy Tesla. The rest buy Chinese LFP with perhaps a side-order of non-Chinese shrinkwrap splattered with Western badges as camouflage. Tesla is - I think - quite rapidly moving from a wining position to a losing position.
I skim read a lot of other folk out there on the web. Most of them get hung up on trying to figure out a bit of the Tesla storage offer. Mostly they miss the storage competitors. And they don't understand industrial dynamics. And they have no idea re the wider energy game. Plus they don't understand well how this meshes with automotive. So they've zeroed in on one leaf on one tree in one wood inside one forest on one continent in a big planet. Plus other stuff. That chap(ess) you linked to is at leaf-level.
After 30-years in the energy game; from oil well to inverter; wind to solar; hydro to battery; 12V to 1.2 million volts; classroom to factory to field .... I try to put things in context.
But that chap(ess) is still saying things that are worth reading, not ignoring.
(And if Tesla think I'm wrong, and wish the market to understand that, then Tesla should publish regular, reliable facts about both their own business and the global market; and answer properly posed questions from knowledgeable people.)
