During the Two Sessions of the Provincial People's Political Consultative Conference, Chen Qizhang, a member of the Provincial Committee of the Chinese People's Political Consultative Conference, carefully studied the work report of the provincial government. Based on the deployment of the report on promoting carbon peak and carbon neutrality, accelerating the construction of new energy systems, orderly promoting the construction of zero carbon parks and zero carbon factories, and his long-term focus on promoting industrial green and low-carbon transformation through zero carbon parks, he put forward systematic suggestions to explore replicable and promotable low-carbon development paths at the park level.

Chen Qizhang talks about using zero carbon parks as a lever to promote the implementation of the "dual carbon" goal

Chen Qizhang stated that in China's "15th Five Year Plan" proposal, it has been clearly stated that the goal of peaking carbon emissions and achieving carbon neutrality will be the driving force to accelerate the green and low-carbon transformation of industrial structure. During the "15th Five Year Plan" period, efforts will be made to build 100 national level zero carbon parks. As a clean energy and industrial province, Sichuan has the practical foundation and pioneering conditions to promote the construction of zero carbon parks.

Currently, Sichuan has launched pilot projects for zero carbon parks in some areas, accumulating preliminary practical experience. At present, there is one national level zero carbon park and four provincial-level zero carbon parks selected in the province. For example, Yibin High tech Zone has completed the first phase of a 232.6 MW microgrid project, which can directly supply 1 billion kilowatt hours of green electricity annually and reduce carbon emissions by over 900000 tons; The Panzhihua West Economic Development Zone is promoting the deep decarbonization of traditional industries through waste heat utilization, equipment renovation, and resource recycling, and exploring the innovative path of "green to green". These explorations have accumulated experience for the construction of zero carbon parks and provided samples for the subsequent systematic promotion.

However, in the research, Chen Qizhang also found that the construction of zero carbon parks still faces many constraints. On the one hand, there are still shortcomings in the maturity and system coordination of key technologies such as source grid load storage integration and smart microgrids. The real-time coordination, accurate load forecasting, and intelligent regulation capabilities of multi energy complementarity such as wind solar hydrogen storage need to be further improved. On the other hand, the models of selling electricity through partition walls and direct supply of green electricity are affected by the current power grid system, and the relevant transaction rules have not been fully relaxed. The green electricity premium and carbon income mechanism are not sound, which restricts the market-oriented realization of low-carbon value in the park.

Chen Qizhang suggested further strengthening policy guidance and market mechanism innovation, exploring the establishment of a linkage mechanism of "zero carbon park green power direct supply+capacity compensation", improving the rules for the connection between time of use electricity prices and electricity spot markets, and activating the value of zero carbon parks in peak shaving and frequency regulation. At the same time, we will accelerate the capacity expansion and flexibility transformation of the distribution network, promote the integration of source, grid, load and storage, and the implementation of key technology scenarios such as smart microgrids, and build a unified smart energy system operation platform.

In terms of financial support, he suggested building a full cycle support system of "fiscal guidance+financial innovation+market synergy+risk sharing", exploring the bundled trading model of "green electricity+green certificates+carbon quotas", providing subsidized support for photovoltaic, energy storage, microgrid and other projects in the park, reducing the investment burden of enterprises, and promoting the rapid implementation of projects.

In his view, promoting the "dual carbon" goal through zero carbon parks is not only an important path for adjusting energy and industrial structures, but also a practical choice for promoting high-quality development in Sichuan. By taking the lead in solving problems and systematically promoting at the park level, it is expected to explore and form a replicable and promotable low-carbon development model for the whole province and even the whole country.
