This.

Before PUCT pegged the prices, we were able to load-shift our showers, heat, and device charging to parts of the day where there actually was still sufficient supply to drive prices down under 50c/kWh.

Even if you aren't shifting your use around, there's a really big difference in the total damage done by power rates pegged at $9/kWh 24/7, and power that was occasionally hitting this rate but was otherwise ~averaging somewhere on the order of $2-3/kWh over a 24h period early on in the crisis.

The day before PUCT pegged the rate had a few hours of relatively tolerable prices. Thankfully we lost power for nearly a full day of the fixed $9/kWh rate.
