I am reading more about this project now. See this statement "Bittwatt platform connects the back offices of Bittwatt ecosystem partners, turning Europe into a single “charging network”." Getting partners on board should be on going. But this statement is huge and this will also make the Bittwatt project huge.

thanks for the link, i found this in the business-plan:
The Bittwatt Energy Wallet
This functionality allows platform users to leverage energy storage through smart devices so as to purchase energy
when it is cheap or free, and either use it or resell it when prices peak.
So we will be able to trade with energy! as easy as on a cryptoexchange! that will be great, a really great feature
As far as I understand it, this is about the prices on the energy exchanges. I'm not exactly the big energy expert right now, but I think there will be moments when there's too much power available and demand is not enough. Then it may be that you get electricity on the exchanges very cheap or even free. But how the physics works, that I can not answer, I still have a lot to read.
