I may be cynical here but the problems described in the above either don't seem like problems or they don't actually solve them. I've never wondered "who touched my electrons". I've never thought "I wish I could audit my electric utility's transaction history through a blockchain". They talk in the article about about having backup power if the main grid goes down, but there's no new wiring here so it doesn't do that.
I just have no idea what value this company provides other than a box that tells you who touched your electrons.
