On July 30, the first phase of Sichuan Yongxiang Energy Technology’s 120,000 tons per year high-purity crystalline silicon production project was launched in Leshan City, Sichuan Province.   Ma Biao, head of the installation team for Yongxiang Energy Technology’s first-phase 120,000-ton/year high-purity polysilicon project, said: “Once the high-purity polysilicon project in Yongxiang Energy Technology’s first phase comes online, its annual output value could reach nearly 40 billion yuan. Green hydropower will be used as the primary energy source for production, and the entire production process will operate in a fully closed-loop system.” ”   It is reported that Yongxiang Energy Technology plans to build a high-purity crystalline silicon production facility with an annual capacity of 200,000 tons, requiring a total investment of around 14 billion yuan and covering an area of over 1,800 mu; the first phase of this project will have an annual capacity of 120,000 tons. It is expected that the project will progress to the main civil construction and installation phases in the first half of next year, with Phase 1 reaching full operational capacity by the end of 2023.

It is understood that Yongxiang Energy Technology plans to build a project for producing 200,000 tons of high-purity crystalline silicon, with a total investment of around 14 billion yuan and an area of over 1,800 mu; the first phase of this project will involve the production of 120,000 tons. It is expected that in the first half of next year, the project will progress to the main civil construction and installation phases, with the goal of achieving full operation and compliance for Phase 1 by the end of 2023. Once operational, this project will be able to generate an annual output value of nearly 40 billion yuan. The entire energy structure will rely on green hydropower as the primary source of energy, and the whole production process will operate in a fully closed-loop system. Furthermore, once the project is operational, it will also provide employment for over 1,200 people. It is worth noting that the built-up area of the core zone of China’s Green Silicon Valley, where this project is located, has reached 10.9 square kilometers. To date, 15 projects related to crystalline silicon photovoltaics and related industries have been established there, with a total investment of 60 billion yuan. These projects have enabled the production of 113,000 tons of high-purity crystalline silicon, as well as 32 GW of single-crystal rods and wafers, giving China a production capacity in high-purity crystalline silicon that ranks among the highest in the world. During the year, the output value of the crystalline silicon photovoltaic industry is set to exceed 60 billion yuan, helping to push the total industrial output value of Wutongqiao District over the 100 billion yuan mark.

Sichuan Yongxiang Energy Technology Co., Ltd.: We have received your company’s request regarding the submission of an energy-saving report for the first-phase high-purity silicon project, as well as the report issued by Sichuan Engineering Consulting Institute containing its review comments on said energy-saving report (Document No. Chuan Gong Zi Cheng Guo [2022] 351). Upon review, the following opinions are put forward: 1. In principle, the energy conservation report for this project is approved (project code: 2110-511112-04-01-251885). II. Types and quantities of energy consumption in the full-production year: The project consumes 614,441.87 million kWh of electricity per year; 8.9505 million cubic meters of fresh water (which is an energy-consuming medium and is not included in the total energy consumption). The total annual energy consumption is equivalent to 755,149.06 tons of standard coal, or 2,015,369.34 tons of standard coal in equivalent terms (the electrical equivalent values are calculated at 0.1229 kilograms of standard coal per kilowatt-hour and 0.328 kilograms of standard coal per kilowatt-hour, respectively). III. Energy efficiency level. According to expert evaluation, the comprehensive electricity consumption for production is 51.148 kWh/kg, while the electricity consumption in the reduction process is 44.39 kWh/kg – values that meet the requirements set out in the \"Specifications for the Photovoltaic Manufacturing Industry\" (2021 edition), namely ≤70 kWh/kg and ≤50 kWh/kg respectively. The comprehensive energy consumption for the production of polysilicon products is 6.286 kgce/kg. Compared with the energy efficiency levels of similar industries in China, the project’s energy efficiency is at an advanced level for the industry. IV. Based on the implementation of the various measures outlined in the energy-saving report, the project designers and construction units should improve and strengthen the following aspects of energy conservation: (1) Given that major equipment such as electrolyzers, preheaters, electric heaters, compressors, refrigeration units, return pumps, reduction furnaces, boilers, chillers, air compressors, pumps, fans, transformers, and motors account for a large proportion of the total energy consumption, project owners should, when purchasing equipment in the next phase, adhere strictly to the principles for selecting project equipment according to the production scale and process requirements, and use equipment that meets the specified energy efficiency standards. Priority should be given to energy-saving technologies, production processes, and energy-consuming equipment listed in the **Catalogue of Key Energy-Saving and Low-Carbon Technologies for Promotion** and other relevant catalogues. (II) In accordance with the \"General Rules for the Provision and Management of Energy Metering Instruments in Energy-Using Units\" (GB17167-2006), ensure the proper installation of energy metering instruments and establish a comprehensive energy metering management system. In line with the \"Measures for the Management of Energy Conservation in Key Energy-Using Units\" issued by seven departments including the National Development and Reform Commission (Order No. 15 of 2018 issued by the National Development and Reform Commission), set up online systems for monitoring energy consumption, and integrate the data collected from such monitoring systems into the provincial platform for monitoring energy consumption in key energy-using units in Sichuan Province. V. If there are significant changes in the energy consumption processes and equipment used in the project, the types of energy consumed, or the scope of construction; or if the production capacity, annual total energy consumption, and consumption of major energy sources such as electricity, natural gas, and coal exceed the levels specified in these review guidelines by more than 10%, the project developer shall conduct a new energy efficiency assessment and submit it to our commission for review. VI. The Development and Reform Commission of Leshan City is requested to strictly ensure that the replacement projects meet the required substitution volume for this project, in accordance with the provisions outlined in the \"Letter from the People’s Government of Leshan City regarding the submission of information on 3 projects planned for construction during the 14th Five-Year Plan period, including the first-phase production facility of Sichuan Yongxiang Energy Technology Co., Ltd. for high-purity silicon\", as well as the \"Replacement Plans for Energy Consumption during the 14th Five-Year Plan period in Leshan City\". Based on these review opinions and the project’s energy-saving report, effective supervision and inspection shall be carried out over the project’s design, construction, completion acceptance, and operation management; progress in implementing these review opinions as well as any major matters related to the project shall be reported in a timely manner. VII. Please ask the Provincial Energy Conservation Supervision Center to conduct energy conservation inspections regarding the implementation of the energy conservation review recommendations for the project, in accordance with the \"Measures for Energy Conservation Supervision\" (Order No. 33 issued by the Development and Reform Commission in 2016). VIII. Our commission will conduct timely follow-up spot checks on the implementation of the energy-saving review opinions for the projects. IX. The validity period of these review opinions is two years.
