There's a recent podcast about this and blockchain + energy sector in general: https://epicenter.tv/episode/174/ Why blockchain? It enables peer-to-peer buying and selling of electricity (no middle man), which becomes more interesting as the grid itself is becoming more decentralized with solar, etc. Imagine being able to buy and sell electricity directly between you and your neighbors. Lots of questions about how this is metered & controlled, but it seems promising.
