Significant progress! The largest distributed photovoltaic project of "selling electricity through the partition wall" in China is connected to the grid.

Recently, the pilot project of 12 MW distributed generation market trading in Suzhou Industrial Park was officially put into operation. Located in the high-tech zone of Suzhou Industrial Park, the project is divided into two sub-projects, distributed on 10 roof carriers, and is also one of the earliest "pilot projects of market-oriented trading of distributed generation" in China. The implementation of the pilot project of 12 MW distributed generation market trading in

Suzhou Industrial Park has created many national records:

it is not only the first pilot project of "one-to-many" distributed generation market trading in China, It is also the first pilot project of market-oriented trading of rooftop distributed generation in load centers to other third-party energy users, which has a good reference for the follow-up promotion of market-oriented trading of distributed generation. The successful operation of the

pilot project, on the one hand, is in response to the national "double carbon" goal, make full use of idle resources, accelerate the popularization and application of distributed photovoltaic power generation ;

On the other hand, by summarizing the successful experience in the development and construction of pilot projects, innovative exploration is carried out around roof load renovation project, integrated intelligent energy management technology of "source-load interaction", infrastructure technology research of "new energy-based new power system" and application of new business model, etc. Develop green energy substitution, use business model innovation to promote distributed photovoltaic power generation projects, reduce carbon emissions in a wider range, and help regional economy achieve green and high-quality development.

"Selling electricity through the wall" refers to the market-oriented transaction of distributed generation, which allows distributed generation to sell electricity directly to the surrounding energy consumers through the distribution network, rather than selling it to the grid at a low price and then buying it back from the grid at a high price.

Different from the two common business modes of "self-use, surplus electricity access to the Internet" and "full access to the Internet" in the industry, the project of "selling electricity through the wall" takes into account the advantages of both:

its grid-connected form is similar to the "full access to the Internet" mode, but the settlement method is similar to the "self-use, surplus electricity access to the Internet" mode. That is to say, it is settled directly with users through the provincial power trading center.

At present, various regions have actively explored the construction of market-oriented transactions of distributed generation, especially since 2021, the state has issued many important policy documents to encourage distributed photovoltaic and decentralized wind power projects to participate in market transactions, including direct transactions with surrounding users.

Among them, Zhejiang's policy promotion in this field is the most active. In September

2022, Zhejiang Province passed the Regulations on Electric Power in Zhejiang Province, which proposed that distributed generation enterprises could trade directly with surrounding users in accordance with the regulations, which would be implemented on a trial basis from January 1, 2023. Zhejiang's "partition selling electricity" has entered a substantive stage. The pilot project of market-oriented trading of 12 MW distributed generation

in Suzhou Industrial Park is another significant progress in the implementation of the policy of "selling electricity through the wall" after Zhejiang Province.
