Going off of your posts offer the past week or so, you follow power and energy closely and understand the vocabulary and calculations very well. The rest of the world isn't in the same boat. For them (hell, us), a simple form email to customers that said something like "hey, prices are expected to spike by as much as 10x, meaning your daily bills could go up by the same percentage. Track prices here (insert website link). Going off your usage, your bill could look like this." that's it. Now usage is a more informed decision.
(I'd also note here that tracking power prices during blackouts isn't easy. I have a 4 year old phone with a **** battery; keeping my phone charged was a major challenge during a 4 day blackout.)
Also, the hilariously bad management and randomness of the rolling blackouts took away a lot of choice because people had no idea what their power schedule looked like. To give a real example, I probably got 1 hour of power in nearly 4 days, which hit at like 2am Wednesday morning. Power was off when I went to bed, I rolled over and woke up at ~2 and we had some power, and it was off again when I woke up. My bill for that ~1 hour of heating, which I didn't even really opt into because they turned it on in the middle of the night when I wasn't expecting it, was around $30!
I guess you can say that I should have anticipated that the power company might turn my power back on and set everything to off, but I think you can agree that this is getting a bit loan sharky.
Overall my bill will probably only be 75-100 higher so I got off easy, but if they'd done a few more midnight power blasts, I easily could have hit am extra 200+.
