T1 Energy Inc. has entered into a three‑year agreement to supply Treaty Oak Clean Energy, LLC with a minimum of 900 MW of high‑efficiency TOPCon solar modules built from domestic cells that will be produced at T1’s planned G2 Austin fab. The modules meet federal foreign‑entity‑of‑concern (FEOC) compliance standards, allowing them to qualify for the Inflation Reduction Act’s Section 45X production tax credits and domestic‑content bonuses.
The deal is a key milestone for T1’s strategy to capture the growing U.S. market for FEOC‑compliant modules. The G2 Austin facility’s first phase, with a 2.1 GW capacity, is slated to begin production by the end of 2026, after construction started on December 17, 2025. The 900 MW commitment will provide a predictable revenue stream that will help offset T1’s current operating losses and support the company’s goal of turning Q4 cash flow positive through monetization of its $93.1 million in Section 45X credits.
T1’s financial picture remains challenging. The company reported a net loss of $140.8 million ($0.87 per share) for Q3 2025, compared with a $27.5 million loss ($0.20 per share) in Q3 2024. Management has lowered its 2025 EBITDA guidance to $25–$50 million from a prior $75–$125 million range, reflecting the need to conserve cash while the G2 Austin fab ramps up. The 900 MW contract will generate revenue that can be used to monetize the 45X credits and fund the fab’s construction, providing a critical cash‑flow boost in a period of high operating expenses.
Dan Barcelo, T1’s chairman and CEO, said the partnership “demonstrates the growing confidence of a major independent power producer in our domestic manufacturing capabilities.” The agreement also signals that Treaty Oak is expanding its project pipeline with modules that meet FEOC and IRA requirements, positioning both companies to benefit from the U.S. policy environment that favors American‑made solar components.
The deal underscores the broader shift toward onshore solar manufacturing. By securing a large, FEOC‑compliant contract, T1 strengthens its integrated supply chain—partnering for polysilicon, wafers, and cells—while advancing the U.S. solar market’s compliance with new foreign‑entity restrictions. The 900 MW commitment also provides a tangible example of how domestic content bonuses and 45X credits can be leveraged to support large‑scale manufacturing projects, potentially encouraging other developers to seek similar U.S.‑made module solutions.
