Tesla Proposes $10.1 Billion Solar Factory in Texas

Tesla has proposed a $10.1 billion solar cell manufacturing facility in Fort Bend County, Texas, marking the largest single manufacturing investment the company has ever put on paper [1, 2]. The project, codenamed "Project Crystal Sun," is currently a conditional proposal contingent on securing state tax incentives, representing a significant expansion of the company’s domestic energy infrastructure goals [2, 3].

The scope of Project Crystal Sun

The proposed facility would occupy a 3,050-acre site near Richmond, Texas, and is designed to be a fully vertically integrated manufacturing hub [2]. Unlike many domestic solar sites that primarily assemble modules from imported components, Tesla’s plan includes the entire production chain—from ingot and wafer manufacturing to coating, metallization, and final cell testing [2]. The company plans to allocate approximately $1.5 billion toward real property and $8.6 billion toward equipment over a three-year construction window starting in 2026 [2].

Tesla is seeking tax credits under the Texas Jobs, Energy, Technology, and Innovation (JETI) Act, which provides property tax relief over 10 years in exchange for meeting specific investment and job creation benchmarks [1, 2]. The company has explicitly stated that it is evaluating multiple U.S. states for the site and that the project’s economic viability depends on securing these incentives [2, 3]. Without such relief, Tesla estimates it would face roughly $1.1 billion in local property taxes over the next 37 years [3].

Strategic energy ambitions

This proposal serves as the manufacturing backbone for CEO Elon Musk’s stated goal of reaching 100 gigawatts of domestic solar production capacity by the end of 2028 [1, 2]. To put that scale in perspective, 100 gigawatts represents approximately 8% of the total power grid capacity in the United States [1, 3]. The move follows Tesla’s previous expansion in the region, including the $200 million Megafactory opened in Brookshire, Texas, last year [1].

While the filing outlines a massive industrial footprint, industry observers note that such applications are standard site-selection maneuvers [2]. Because the project remains in the early stages of the incentive application process, the $10.1 billion figure and the projected 9,712 permanent jobs function as a negotiating position rather than a finalized commitment [2].

What to watch

• Incentive Negotiations: Monitor whether Fort Bend County establishes the necessary reinvestment zone and if the Texas Comptroller approves the JETI tax credit application [2].
• Equipment Procurement: Watch for further details on supply chain agreements, following reports earlier this year that Tesla was in talks to source $2.9 billion in solar manufacturing equipment from Chinese suppliers [2].
• Construction Milestones: Look for a formal groundbreaking announcement, which the company currently expects to occur within this year [3].

Whether this project proceeds depends on Tesla’s ability to secure public subsidies that make domestic production competitive against alternative sites. If realized, the facility would represent a rare instance of end-to-end solar manufacturing on U.S. soil, potentially shifting the company’s energy division from a niche operation to a primary pillar of its business.
