Case introduction
Boosted by the "double carbon" goal and the comprehensive development of the energy Internet, the wave of energy "digital new infrastructure" is surging, and changes and innovations follow one after another. The "obviousness" of globalization transactions has accelerated the process of clean energy consumption structure and green and low-carbon development.
Renewable energy consumption and market-oriented transactions have a natural fit with blockchain technology.
One is multi-party mutual trust. Renewable energy consumption responsibility weight business involves multiple parties such as electricity sales enterprises and power users, and needs to have strong credibility; the other is peer-to-peer credible transactions. Transactions of excess consumption certificates have financial attributes and need to be provided for market participants. Convenient, reliable, flexible and independent participation experience; the third is traceability, the distribution of renewable energy consumption and transfer transactions need to achieve traceability, and enhance the seriousness and credibility of consumption and bookkeeping; the fourth is monitoring and supervision, the National Development and Reform Commission , the National Energy Administration, and local governments need to dynamically monitor the completion of consumption responsibilities.
After four years of exploration and practice, the State Grid Corporation of China has built the largest energy blockchain public service platform in China - "State Grid Chain", and created a blockchain-based renewable energy power consumption voucher trading system.
On the one hand, build a blockchain identity authentication system, through the blockchain key generation mechanism, endorse the binding relationship between the identity of the market subject and the public key, replace the existing third-party digital certificate authentication method, greatly save authentication costs, and optimize business operations. The business environment has improved the efficiency of the marketization of renewable energy power consumption. On the other hand, based on smart contract technology, core business operations such as consumption account management, voucher electronic signature issuance, voucher transaction, and transaction accounting can be realized on the chain, and the whole process of renewable energy consumption transaction data can be traced and traced to help the government effectively Supervision. The system is of great value in promoting the upgrading of energy consumption and supply structure.
The renewable energy excess consumption voucher trading system based on the State Grid Chain has been used in 27 provincial-level trading markets since November 2020, and has achieved blockchain excess consumption for 10 provinces including Henan, Ningxia, and Jiangsu. More than 2.4 million certificate transfer results. It can complete the issuance of 170,000 transaction subject identity certificates and nearly 200 million blockchain excess consumption certificates every year, reducing market access costs by hundreds of millions of yuan.
Application summary
The successful implementation of this application has verified the feasibility and innovation of the blockchain technology solution for renewable energy consumption transactions, breaking through the "1 to N" transaction mechanism of traditional power transactions, improving transaction efficiency, reducing trust costs, and building clarity The value of the renewable energy consumption market environment is significant.
Value
By building a blockchain transaction system with multiple subjects such as power generation, power transmission, and power consumption companies. On the one hand, the blockchain smart contract is used to realize on-chain transactions for the first time, and the transaction declaration and clearing of renewable energy consumption certificates are all completed by invoking smart contracts, realizing the operation of the entire business chain and ensuring transparent, credible, and efficient transactions.
On the other hand, the blockchain electronic signature is used to issue consumption certificates, including information such as the origin of electricity, consumption places, consumption subjects, consumption time, consumption electricity, etc., to realize the traceability management of the whole life cycle of renewable energy power consumption , Realize the sharing of data rights, fully stimulate the potential of both supply and demand, and promote the development of green energy.
