Tesla files to become an electricity provider in Texas

"The Texas grid is isolated from the rest of the U.S., so transmission of power from other states was not available to relieve those stuck in the cold."

Not quite true, as I understand it. We are able to buy from the eastern grid, but not from the western one. There is also a link to the Mexican grid.

This wasn't a good look the other week at the Geelong battery:

But the Hornsdale unit has paid for itself multiple times, and shown how a battery at this scale can support every other asset on the grid.

How does it compare to a hydroelectric plant with a storage lake? IMO the hydro plant is an initially larger investment and has some impact on the surrounding area but it will last for generations. It can also run at full capacity within seconds and future efficiency improvements in generators are easily upgraded.

Australia has a massive hydro system - the Snowy.

But it's over 50 years old at least and wouldn't have the control systems. Hornsdale has some pretty impressive software allowing it to go from charging to jumping in so fast.

Every power grid should be building a few of these installations at a minimum. They are just so effective at stabilizing grid frequency with sub-second response times between demand and load. With Texas wholesale power pricing and emergency rates I wouldn't be surprised to see smaller grid battery installations paired with existing natural gas generators to help improve their response to demand.
