T1 Energy advances $850m solar cell facility development in US

T1 Energy has announced the next step in the development of its $850m G2_Austin 5GW solar cell facility with the selection of Yates Construction for preconstruction and site preparation services.

The development of G2_Austin is integral to T1’s broader strategy of establishing a domestic supply chain for solar and battery technology, enabling the US to access scaleable, dependable and cost-effective energy solutions.

T1 intends to meet growing demand within the US market for solar cells and modules that utilise TOPCon technology through the G2_Austin, along with its operational counterpart, the G1_Dallas 5GW solar module facility.

The project is facilitated by the tariffs and other policies implemented by the Trump administration, which support American advanced manufacturing, job creation and energy dominance.

The Milam County commissioners in Texas have unanimously agreed to offer T1 Energy a substantial tax abatement package, contingent on the company achieving certain employment and investment milestones at the new facility.

T1 CEO and board chairman Daniel Barcelo stated: “Solar energy is a foundational part of American power grids. Our facilities will manufacture solar cells and modules to invigorate our economy with abundant energy. We’re excited to work with Yates and Milam County to bring American advanced manufacturing to the heart of Texas and to unlock our most scalable energy resources.”

Yates Construction’s engagement extends beyond preconstruction duties as T1 Energy anticipates finalising terms with them as the general contractor.

The company joins SSOE Group, which has been providing project engineering services for the project since December 2024.

The G2_Austin facility will commence cell production by late 2026 and is expected to generate up to 1,800 full-time positions.

Yates Construction president and CEO William G Yates III stated: “We look forward to working with T1 Energy and leveraging our extensive experience in advanced manufacturing facility construction.

“This is an exciting project, and Yates Construction is committed to being a collaborative partner throughout the execution of the project.”

In May 2025, T1 Energy entered into a heads of agreement with Saudi partner Manaar Gulf Saudi Arabia, to explore an investment in the proposed G2_Austin 5GW solar cell manufacturing facility.
