Tesla wants to use Powerwalls as small power plants

Tesla Inc. is hoping to turn some Texas homes into “virtual power plants” after tests showed its home batteries can be quickly tapped to reduce stress on the state grid.

Tesla is making the push after trying a project that pooled together 64 northern Texas homes outfitted with rooftop solar and Powerwall batteries.

Have they swapped to LFP yet or still on NMC

Bloomberg - Are you a robot?

Do you know that they actually use NMC in that installation, because LFP is cheaper and makes more sense in this use-case. (Tesla uses LFP in the standard range model 3.) Also, that fire was caused by a coolant leak; IIRC it happened within the first week of operation - so probably an installation error.

Cars started swapping as well:

Tesla will change the type of battery cells it uses in all its standard-range cars

The move is likely a way for Tesla to increase profit margins on its vehicles, while not necessarily having to raise vehicle prices.

Only started chem change last year on megapacks:

Tesla shifts battery chemistry for utility-scale storage Megapack

The move to cobalt-free lithium iron phosphate batteries for the 1 GWh product could signal supply chain shifts.

Pumped storage is way more cost effective

China is opening their 1st Compressed air storage... with our vacant mines that might also be something to look at:

China’s first salt cavern for compressed air energy storage goes online

Huaneng Group has finished building a 300 MWh storage project in Changzhou, in China's Jiangsu province. The state-owned company has already started operating the facility, which is situated in a salt cavern.

Only if you already have the dams.

I stay in a boomed, fenced off security village and was thinking could we not start our own backup system to get away from Eskom like we shared the cost of fencing off our area to get away from crime?

The options are certainly becoming feasible and looking more attractive financially the more Eskom screws up and make us pay for their mistakes..
