Texas has all sorts of options. Most power usage here is structured where individuals can select which Retail Electric Provider (REP) to use. They essentially wholesale energy from the grid. I had the (dis)pleasure of searching for a new contract after ours expired so have a refreshed memory of options: - flat rates

- discounted for more or less spend

- credits issued at X usage (which is only good at X specifically because its generally an expensive rate but it’s a marketing ploy for filter based searches).

- free or discounted night time or weekends

- etc.

If you can imagine they charge a certain way, there is likely someone trying it.
