Tesla Submits $10.1 Billion Investment Plan Targeting 2029 Production
Tesla has formally submitted its investment plan for "Project Crystal Sun," a solar cell factory in Fort Bend County, Texas, with a total investment of $10.116 billion, aiming to begin commercial production in the first quarter of 2029. According to documents released by the Texas Comptroller on August 6, 2026, the project is expected to create 9,712 permanent jobs and span approximately 3,050 acres, making it Tesla’s largest proposed manufacturing investment in the United States.
In the application signed on July 22, 2026, Tesla stated it will build a fully vertically integrated solar manufacturing base in Fort Bend County, covering the entire production process from polysilicon raw materials, ingots, and wafers to solar modules. This vertically integrated model is currently dominated by China, while most U.S. manufacturers focus only on module assembly, with critical solar cells still reliant on imports.
Tesla CEO Elon Musk stated at the World Economic Forum in Davos in January 2026 that Tesla and SpaceX teams are working toward a goal of producing 100 GW of solar cells annually in the U.S. Tesla cited this target in its application, emphasizing that the project will help enhance U.S. solar manufacturing self-sufficiency.
Tax Incentives Critical to Investment; Tesla Threatens Relocation
Tesla explicitly stated in its application that without the 10-year property tax abatement under Texas’s Jobs, Energy, Technology, and Innovation (JETI) Act, Fort Bend County’s investment conditions would be less competitive than those of other states. The company noted that property taxes are a major operating cost for solar manufacturing plants and hinted at the possibility of relocating the investment to another state.
A economic impact assessment prepared by consulting firm Kroll for Tesla projects that the plan would add $107 billion to Texas’s GDP and generate $6.4 billion in state and local tax revenue over 38 years. However, Tesla stressed that these benefits depend on the approval of tax incentives.
The company also mentioned in its filing that the project will leverage federal incentives, including the Advanced Manufacturing Production Credit (Section 45X) and the Domestic Manufacturing Equipment Credit (Section 48D), to reduce investment costs. Of the $10.1 billion investment, $1.5 billion is allocated for land and facility construction, while $8.6 billion will be used for equipment procurement.
