In Texas griddy exposes you to real time spot pricing. I was frequently getting paid to use electricity at night due to excess generation by wind. As an electric car owner this was fantastic as I frequently got paid to recharge my car. My average delivered rate before this week was 7c/kwh all in.

Does anyone there get a battery system, like a Tesla Powerwall, to save up negative priced night electricity to use in the daytime?

It doesn't happen enough that I've seen to make it worthwhile

Of course, during these cold snaps, the battery doesn't really work well, right?

Powerwalls have an operating temperature range of -4 F to 122 F (-20 C to 50 C), although they recommend 32-86 F (0-30 C).

They can also be mounted indoors.
