A Distributed Ledger Based Platform for Automated Energy Performance Assessment

This paper presents a decentralized district energy management platform leveraging permissioned Blockchain, Smart Contracts, IoT, and Cloud Computing. This platform facilitates digitizing assets and data in a decentralized energy ecosystem in a trusted manner without a central point of authority, enabling the implementation of distributed applications to create new value-added services. As part of the distributed application design, this paper investigates Blockchain integration and trust aspects. Different Blockchain configurations are deployed and analyzed under real-world operating conditions, using a Blockchain network based on the Hyperledger Fabric framework. Our analysis shows that the platform can handle up to 150 transactions per second with a 0.5 second latency under the baseline configurations provided. The paper further investigates strategies to improve scalability to meet future application requirements.
