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.
