Macau Carbon Exchange (MCE) Completes First International Green Certificate Transaction for Brazilian Household Solar PV, Ushering in a New Era for Global Household Solar Green Energy Trading

On January 10th, the Macau International Carbon Exchange (MCE) officially announced the successful completion of its first international green certificate (I-REC) transaction for Brazilian household photovoltaic (PV) systems. This marks the formal integration of the vast global household solar PV market into the green energy trading system. This I-REC transaction, sourced from a household PV project in Paran, Brazil, is not only MCE's first I-REC transaction but also a pioneering application of blockchain technology. The technology puts on the chain the source of the green energy data, enabling end-to-end digital management.

The successful transaction significantly reduced the green certificate issuance timeframe. Previously, issuance often took a month or longer; however, leveraging blockchain technology, the process from electricity registration to green certificate trading was completed in approximately one week. This dramatically improved efficiency, breaking down data trust barriers inherent in traditional green certificate trading and injecting new vitality into the green energy market.

International Green Certificates, also known as Guarantees of Origin (GOs), act as the "electronic ID" for renewable energy. Each certificate represents one megawatt-hour (1000 kWh) of green electricity generation. Against the backdrop of the global push towards carbon neutrality, green energy trading has become a crucial driver of renewable energy development. Energy companies can purchase green certificates to offset their carbon emissions and reduce the carbon tariffs on exported goods.

The household PV I-REC project involved in this transaction was developed by Yingzhen Technology's operation of household PV power stations in Paran, Brazil. REDEX handled the green certificate registration, and GreenCertificateCompany (GCC) completed the issuance. GCC is an I-REC(E) central issuer accredited by the ITRACK (International Tracking Standard) Foundation, and I-REC international green certificates are among the most widely recognized and accepted energy certificate standards globally.

Traditional green certificate registration relied on entirely offline or semi-automated methods, depending on manual registration or data extraction from power system backends. This made data authenticity and reliability difficult to guarantee. For distributed household PV projects on rooftops, the cost of data registration and verification was often exorbitant, even exceeding the potential revenue from green certificate trading. This significantly hampered the participation of household PV systems in green energy markets.

This project successfully connected the blockchain system with the registrar and issuer's system, enabling real-time collection, transmission, calculation, and authentication of green energy data. The underlying integration of Ant Chain's blockchain and IoT technologies ensured data authenticity, integrity, and traceability. This significantly reduced certification costs and created the necessary conditions for transparent green certificate management and trading.

The global distributed PV market holds enormous potential. The International Energy Agency (IEA) predicts that by 2030, new solar installations will account for 80% of renewable energy growth, exceeding 4000 GW. While utility-scale solar will dominate, distributed applications (including residential, commercial, industrial, and off-grid projects) are projected to account for nearly 40% of new solar capacity.

In its official WeChat account, MCE stated that with the support of digital technologies such as blockchain and IoT, future distributed household PV projects will be more easily integrated on a large scale. Issuance periods will be further shortened, potentially reaching real-time issuance. These technologies enable even small-scale household PV systems to be effectively integrated, providing farmers with more convenient and efficient revenue streams. This transaction not only offers a new model for the participation of global household PV projects but also provides strong support for further renewable energy development.

Through this transaction, MCE successfully applied blockchain technology to green certificate trading, improving efficiency, transparency, and trust. This has significant demonstrative value for global renewable energy development and provides a viable pathway for more household PV projects to participate in green energy trading.

This blockchain-based innovation represents a breakthrough for the global green energy trading market. It addresses the past challenges of ensuring data authenticity and lengthy issuance periods. More importantly, it opens the door for the vast global household solar PV market, allowing more small-scale and distributed clean energy projects to participate in green energy trading and access more efficient revenue generation.

The success of this transaction provides a valuable reference for household PV projects in other countries and regions to participate in green energy trading. In the future, with technological advancements and supportive policies, more and more household PV projects will be able to generate revenue through green energy trading, further promoting the development and application of global renewable energy. In the near future, green energy trading will become an indispensable part of the global energy market, contributing to the achievement of global carbon neutrality goals. This innovation has far-reaching implications for Brazil's energy market and provides valuable experience and reference for household PV development in other countries globally, driving progress towards sustainable energy development.

MCE's successful attempt heralds the future direction of the global green energy trading market: higher efficiency, greater transparency, and increased convenience. This will further promote the widespread adoption of global renewable energy and ultimately contribute significantly to achieving global carbon neutrality goals. With continued technological maturation and market development, we can expect to see more similar innovations in the global green energy trading market.
