The majority of consumers at home would against spot pricing like that. California already has time-of-use pricing. Peak hours are 4-9pm when there's no solar. Peak usage is people coming home from work, turning on their lights, stoves, hot water, ovens, air conditioning, etc. Are they supposed to not do that?

Raising those rates too much would just be raising rates for everyone, just so those who are rich enough to afford solar panels and batteries make more profit.
