The hype around blockchain provided some rather discouraging scenarios for companies in the German electricity system. Our new analysis recently shows that blockchain currently has no disruptive potential for peer-to-peer power transactions. The study illustrates that while platforms (e.g., based on blockchain technology) for peer-to-peer transactions do not face organizational or regulatory barriers, levies, taxes and surcharges on final consumer power consumption burden the disruptive potential of the technology and hamper deployment. Public blockchain-based platforms will come with additional costs for underlying distributed mechanisms.
