I have a Powerwall and solar. My electric company offers no incentive for me to use my powerwall, or to feed into the grid during high demand.

It's in the grid's best interest that I store power generated during daylight and trickle it back during the night.
Texas's problem has to do with its electric plants inability to operate in cold weather. Fortunately, domestic solar doesn't have that kind of limitation.
