Peer-to-Peer Energy Trading
"Dutch peer-to-peer energy trading network PowerPeers runs its system using already-available infrastructure and smart meter data.
Co-founder Michiel Ooms says the company is looking for ways to integrate blockchain, but has encountered several roadblocks.
“The biggest challenge we see so far is the handling of privacy-sensitive data,” he says.
“Using the blockchain brings more transparency, including on data exchanged. And although our whole vision is about making the energy market more transparent, sharing privacy-sensitive data (such as consumptions, locations, financial transactions) probably would not comply with the GDPR regulations that come into effect in the EU in 2018. Legislators therefore also have quite a bit of work to do if they want to enable everyone to participate in the future energy landscape.” (https://www.theguardian.com/sustainable-business/2017/jul/13/could-a-blockchain-based-electricity-network-change-the-energy-market)
