Also, we can charge EVs. Grid connected batteries may or may not use the energy, but EVs will use some portion of it every day, and can be charged again the next day when there is excess energy.

Power price goes negative +200M times/year, just in the US and it is increase. It would be wonderful to get paid for charging EV. Tesla Electric customers report making as much as $150 a day[1]. Car batteries are bigger than powerwall, EV owners can make quite a bit of money by participating in VPP (Virtual Power Plant).
