Privacy-Preserving Energy Trading with Applications to Renewable Energy Communities

We present a comprehensive framework that enhances coordination, privacy, and incentive alignment within RECs, while empowering them to establish a trustworthy reputation in the eyes of relevant external stakeholders. Our privacy-preserving energy trading protocol enables secure communication of energy supply and demand. With tokenized incentives, users are encouraged to publish usage profiles and trade energy in a community-controlled public forum. This allows all users in the community to benefit from typically cheaper locally produced renewable energy, while also allowing the community as a whole to more effectively balance energy supply and demand, without compromising sensitive data confidentiality. With our blockchain-based protocol, we aim to contribute to the further adoption of sustainable energy at a community level, laying a foundation for more extensive societal and environmental benefits in RECs.
