The public document shows that the production line optimization is mainly for the expansion of the stamping workshop, body shop, painting workshop, final assembly workshop and logistics operation center. At the same time, Tesla said that the project will increase the working hours, increase the number of employees and improve the frequency of material turnover to achieve capacity improvement, and the production line optimization is expected to add 4,000 employees after completion. The total investment in the Tesla Shanghai Superplant production line optimization project is RMB 1.2 billion, of which RMB 85 million, or 7.08%, will be invested in environmental protection. The Tesla Shanghai Superplant Line Optimization Project will commence on December 21, 2021, and will be completed today for commissioning, with an expected acceptance period of September 19, 2022 to November 30, 2022. The production line optimization project is Tesla's expansion of the existing factory, mainly by increasing the production tempo to expand production capacity. We know from Tesla China's website that Tesla has further shortened its estimated delivery time in China. Currently, both Model 3 and Model Y produced at Tesla's Shanghai plant can be expected to be delivered in 1-10 weeks (the original delivery cycle was around 6-14 weeks), which means some models can be delivered in as little as 1 week. As previously announced, Tesla's Shanghai plant was upgraded this summer and generated 77,000 deliveries in August, nearly tripling the number of deliveries in July and up 74% year-over-year, which is a side note to the significant increase in production at the Shanghai plant. In addition, the European plant in Berlin is also increasing production of the Model Y, which also allows the Shanghai plant to export fewer models and thus achieve an increase in supply to China.
