Having an EV would be the main reason, I assume. Wholesale prices are often close to zero or even negative on some nights or on very sunny days during weekends.

It might also be worth if you have some heating/cooling system and stuff like that. If your usage patterns are closer to the average you probably won’t save more than 2-3 cents per kWh but taken on significant risk so it’s probably not worth it.
