1. Time-of-use plans have an app or web portal into which a customer can log into. (Actually, most providers in Texas these days have a real-time portal customers can use simply because smart metering enables it.)

2. Yep, my parents were, and they will never use a time-of-use plan ever again.

3. No. I made a spreadsheet and, based on my math their being bit by this in mid-2019 would have not paid off prior to this event.

Circling back to 2 for a moment, the problem is not so much with the plans, it is with all of the unmet caveats that the author lists in the article.

For my parents, they were pitched this plan on a visit to the State Fair of Texas where the salesperson told them they could "save thousands of dollars" every year by not "lining the pockets of big energy." Sure, they know how Griddy operates now, but what about some new clever scheme another provider comes up with that winds up biting them? That's why they're on fixed-rate plans forever.

Not a single person told them the downsides of this plan, the virtually-unlimited (sorry, but a $9/kWh cap when wholesale electricity is usually $0.02-$0.04/kWh and retail is around $0.115/kWh, is not a cap) cost exposure, and the near-impossibility of taking effective action (it is unreasonable to tell customers to go outside and hit the main breaker in a winter storm).

Texas came up with a system where retail electric customers are willingly offered plans in which they need to be near-experts in the price of natural gas derivatives and spot-generation electrical wholesale rates...and are not told in advance about this requirement.

Yeah, that's kind of ridiculous. Like picking pennies up in front of a steamroller.

Granted, if the cost savings were enough, a homeowner could install a battery/genset backup with the savings and have that automatically switch over when prices got nuts, but that's not within the abilities or even mindset of most people.

> Granted, if the cost savings were enough

They probably are enough over long periods, or retailers wouldn't be profitable.

However that assumes you hedge properly. If you treat your savings from "good times" as extra cash to spend you're going to get burned to the ground by the bad times.

It also means you have to be extremely reactive, now you need a setup to quickly cutoff electricity if wholesale prices skyrocket, and you need to be on the ball checking wholesale prices like a whale checks their gasha.

Exactly, though to give a lot of customers of these plans credit, they don't have the extra cash. Griddy's own marketing says that "96% of the time," the wholesale rate is well under the average retail per-kWh rate.

This is yet another one of those hidden costs of how being lower-income is very expensive, both in actual money, and in time. Vanishingly few people have the time to be as on the ball as they'd need to for plans like this to work. And you can automate it, but that costs money many of these customers don't have.

I have no problems with plans like this existing; my issue is we set people up to fail by danging the large-print number being a very small value, while not warning people of how catastrophically it can go--and has gone--very wrong.

I would agree with that. Griddy specifically marketing towards poorer populations by touting savings is really objectionable at the best of times.
Datapoint: I'm someone on the MISO grid, with fixed-rate electric billed at $0.15 for the first 300 kWh, $.11 for the next 700 kWh, and $.10 for the rest. Last month I used ~2500 kWh for a total of ~$267.

MISO's marginal cost to deliver a megawatt hour to my area is around ~$16-19 over the past hour or so[1]; with those prices, I'd save ~200. That's nothing to sneeze at.

During the blackouts ERCOT's prices[2] were around $7500 to deliver that mWh; at that cost I'd lose $18,483 by paying market rate.

I don't think the average person is equipped to properly price this risk. I don't think I'd know how to properly hedge it, either.

I would agree with that.

As a nerd-snipe for hyper-optimisers and misers, griddy would be a good if risky (to clients) business. Publicly advertised to the general population it's at best unethical and at worst unconscionable and insane.
