The biggest draw is A/C. It dwarfs other usage. And unfortunately, A/C is sometimes required to avoid death. Precooling isn’t effective in that the A/C will still run for nearly as long during peak.
- pfdietz 3y agoPrecooling allows cheap pre-peak power to be used instead of very expensive peak power.
- fragmede 3y agoThat's the critical thing. A/C isn't just a luxury anymore. As the Earth heats up, A/C becomes am absolutely necessity to avoid dying from temperatures exceeding the wet bulb temperature, where human sweat is no longer sufficient to cool people off, especially the very young or very old. The heatwaves across Europe a bunch of years back killed some 70,000 people from the heat.

- gnicholas 3y ago> Precooling isn’t effective Interesting, PG&E tells me to do it when the temperature is expected to be high. I've done it on occasion and it has seemed to work. I'm sure it's a YMMV situation, depending on insulation and other factors.
- fulafel 3y agoOTOH there are plenty of more energy efficient alternatives that avoid death to cooling an entire poorly insulated, oversized house without ventilation energy recovery at peak demand times using fossil fuel generated grid electricity.
