On power markets, snow storms, and $16k power bills

Traditionally they sent a technician out to read each meter and turn off the electricity if necessary, but there are newer "smart meters" that communicate your usage to the power company (although I'm not sure if those can also be remotely triggered to turn off your power, I would suspect not).

Where I grew up in a small town in the Midwestern US in the 1990s, the meters were usually installed on an external wall at the back of the house. My part of town had underground power lines (good during thunderstorms, bad during road/building construction) and I suspect the meter was right where the buried cable came into the house. Every month a uniformed person from the power company would walk through everyone's backyards taking the reading from each meter.

Fun fact: most utilities and similar services have historically worked this way. I think the cable television company would just send someone to the cable box on the back of your house and flip switches to enable the channels you were paying for. There was always some kid who claimed to get HBO for free because his older cousin worked for the cable company.

Now that I think about it, I recently got a car that's new enough to have Sirius XM satellite radio built in, and I've been wondering how their access control works. Surely the satellite doesn't beam down everyone's subscription status and make their receiver hardware respect that, right? Is my car using the built-in cell phone to check whether I'm subscribed to the satellite radio? Either way, where are the bootlegged satellite radio receivers?

In my experience, there are exactly two types of customers on the kinds of plans like Griddy offers: a) people who are heavily into cost-optimization and have spent the cash to automate their living quarters to take advantage of wholesale price swings; and b) people who are trying to stretch a dollar because a single dollar is all they have left.

For people in that second category, the dollar broke and smacked them in the face.

I am by no means calling people stupid for doing this; they believed the sales pitch and either did not understand (because the wholesale pricing model is actually complex) or were not told the massive potential downsides. And when the cost of keeping where you live at a livable temperature runs into the mid-three-digits per month during the summer, you're going to jump at the idea of slashing that by two-thirds.

This is consent in the same way that clicking "agree" on a 15,000-word EULA is consent. It isn't.

The text is triggered if retail rates go above 14c per kWh for more than 30 minutes. That’s about 7x our normal peak rate.

Last week saw the highest prices I’ve seen going up to 40c at one point.

I’ll also note that I’m on budget billing which normalizes monthly fluctuations. No idea what the agreement is in the case of one of these tail events but I suspect it involves lots of publicity and regulators.
