T1 Energy Inc. has begun construction on its G2_Austin solar cell manufacturing facility in Milam County, Texas, representing an investment of $400 to $425 million. The first phase of the project will have an annual capacity of 2.1GW of high-efficiency TOPCon solar cells and is expected to start production by the end of 2026. This expansion is set to create up to 1,800 advanced manufacturing jobs and will significantly increase the U.S. capacity for silicon-based solar cell production. The new facility will support T1 Energy's strategy to build an integrated domestic solar supply chain, with cells from G2_Austin to be used in solar modules produced at T1's existing Dallas facility. Further expansion is possible, with a second phase planned to add an additional 3.2GW of capacity.
