Powerledger are relative new IMO but could work well if you actually look at their whitepaper.
While we have Gigawatt tokens too, but i think they are not fully focusing on the Energy market but more on Energy vs Mining Profit ratio as IIRC their mission is to get the highest mining profitability while lowering the cost of electricity
Yes - I did check their whitepaper and the whole space is very interesting and of course I believe in the sector strongly. Their pre sale was also very impressive considering their geographical focus. However, I decided against it due to the structure and the belief that they will be outplayed relative quickly by other players in the long run.
Will have a look at the Gigawatt tokens as you mentioned, thank you - have just scanned them before, but will check in detail.
Generally I find it amazing that there are not more energy projects but as I said above, to make it real it has to be a serious large team with experienced professionals that already has the connections to the state run utilities and pilot projects already going, which narrows the space.
Prosume Energy seems to be alone for now.
