It is easy to sell extra electricity back to the national grid as we are already connected to it. But how do we give this extra electricity to the buyer after creating a contract?
Great idea, but struggling to see how the logistics will work - perhaps we need permission and setup payment to the national grid to setup a channel specifically from your home to the buyer (if they will even allow it)?
I believe the idea is that the idea was to have a power grid that relied solely on this and had nothing to do with national grid -- it's very interesting tech, but it's really up to somebody who's not the developer and in need of something like this to adopt this coin.
National grid will still distribute energy (this might not be the case in local communities). But platform will provide you an opportunity to buy electricity directly from producer. As you would buy flour directly from miller instead from Tesco/Aldi/etc
