This is a poor policy for something that is an essential utility, this isn't just "republican bashing".
It's a very useful policy that can allow both buyers to save on costs, if they're careful; and utilities to decarbonise faster and introduce more renewables. For example, I know that a lot of people are taking out their natural gas heating in the UK and replace it with electric heaters that can be charged overnight when the electricity is cheap.
I would like more demand response in the US, it's a low hanging fruit. We need better protections in extreme circumstances, but that doesn't make it less useful overall.
If you have an EV or if you plan other energy intensive activities smarter (like heating/cooling, washing+drying), you can save significantly more than 20 bucks a month.
This is not a unique Texas solution to this problem. In the UK for example, a lot of people take out their gas heating and replace it with electric ones that can be "charged" overnight at cheap prices.
It's the same think with credit cards and loans: they can absolutely wreck uneducated people, but they're not essentially bad if you know how to use them, they're quite advantageous.
When the situation became a state of emergency, they could have stopped free trading and just provide everything they can, leaving the accounting for later. Or just capping the price to a lower level.
In the meantime, spot pricing would be a very good thing to happen all across America, as I said - it's contributing massively to the de-carbonification of UK. Demand response would help reduce a lot of the spikes in usage, and make renewables integration easier.
It seems to me that a lot of what happened was politicized just so people can trash the republicans.
