Those prices are far below normal prices. Normal is 28-50 cents in places like San Diego (https://www.sandiegouniontribune.com/business/energy-green/s...).

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?

[rstupek]

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

[manyes]

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

[tzs]

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.

CA power is hilariously expensive compared to the rest of the country. 10c is much closer to average.

The weighted average price is 10.54¢ per kwh. In California it's 16. Both 5 and 35¢ are pretty poor estimates.

I paid $.36 last month living an hour north of SF.

Average or marginal? Most PG&E customers have a “baseline allowance” with a higher marginal cost as you draw more energy over the month.

[kevinventullo]

Marginal. I was doing a back-of-the-envelope calculation about getting an EV and realized that the $/mile cost to charge it would be about the same as paying for gasoline on a car which gets 30 mi/gallon.

My power comes from, I believe, a nuclear plant in Wisconsin.

$0.098 per kW-h, with $15 a month connection fee.

[bfrog]

Wi has a lot of coal by the lake, where is there a nuke? Chicago was almost all nukes at one point

[khuey]

Point Beach is still operating afaik. Kewaunee shut down several years ago though.

I'm paying 8.5-8.3 cent kWh on a fixed contract.

Power is very very very cheap in Texas.
