That is what utilities need to be doing. Right now, they refuse to do much about energy storage, and home owners with solar or wind generation have to buy expensive batteries to buffer their production. That is stupid expensive for individual producers and is something a utility needs to take over. They just don't want to because it's more lucrative to burn fossil fuels and charge for that.
