Blockchain-based renewable energy certificate system in Indonesia

Abstract

The renewable Energy Certificate (REC) schemes play a crucial role in combating climate change and promoting sustainable living. However, issues such as traceability, lack of transparency, and user awareness limit its effectiveness. The current study aims to address such limitation by proposing a blockchain-based solution for Indonesia's electricity grid which can enhance end-to-end traceability, real-time data access, and tamper-proof records. The methodology encompasses interview with energy stakeholders, blockchain model development, prototyping, and evaluation of its efficacy. Results show that blockchain technology can revolutionize Indonesian REC market by improving security, traceability, and promote stakeholders' trust. The proposed framework addresses current system limitation and introduces a semi-fungible REC token for secure issuance, trading, and verification. Our solution offers a scalable model that can support Indonesia and global green energy adoption and sustainable living.
