T1 Energy said on 30 October 2026 that it has signed new offtake deals “totaling more than 1.58GW of advanced solar modules”, according to its release. The company said it “now has more than 4GW of its 2027 manufacturing capacity under contract”.
T1 said the buyers include subsidiaries of independent power producer Avantus, and that it expects to supply the modules from its G1_Dallas facility in 2027 and 2028. Measured against the 5GW rating T1 gives G1_Dallas, more than 4GW is more than 80 percent, by our arithmetic.
Short explainer · T1 Energy Has Over 4GW of 2027 Solar Output Under Contract
A vertical news Short narrated from this piece’s headline and opening line.
Business Pill · Grid Cost Allocation
A one-minute explainer of grid cost allocation: who pays for a new power line as electricity demand grows. It teaches the general idea only and says nothing about T1 Energy, Avantus or this story.
The key insight: T1 Energy says it has signed more than 1.58GW of new solar module offtake deals and now has more than 4GW of its 2027 manufacturing capacity under contract, more than 80 percent of the 5GW rating it gives its Dallas module plant, by our arithmetic.
The release says T1 expects to supply “high-performance, high-efficiency, TOPCon modules from its G1_Dallas solar module facility in 2027 and 2028”. It says the modules are expected to use “a blend of imported solar cells and domestically produced cells from T1’s G2_Austin new solar cell fab”.
Chairman and CEO Dan Barcelo said in the release: “America’s AI infrastructure and energy grid need high-efficiency modules—and we’re building them here, in Texas”. The release does not say which projects the modules will go to, or whether any will power data centres.
T1 Energy’s own figures: the 5GW rating of its G1_Dallas module plant, more than 4GW of 2027 capacity under contract, the first 2.1GW phase of its G2_Austin cell fab, and more than 1.58GW of new offtake deals. Separate measures, not additive.
The Texas Factories
T1 says it began construction of G2_Austin, its solar cell fab in Rockdale, Texas, in December 2025, and that “The first 2.1GW phase is expected to produce cells in Q1 2027”. The company says it “expects to offer modules with greater than 60% domestic content in 2027”.
The release describes G1_Dallas as T1’s 5GW solar module facility. In July, T1 says, it acquired foundational TOPCon solar patents and other intellectual property.
Counting the Gigawatts
The first 2.1GW phase of G2_Austin cells equals 42 percent of G1_Dallas’s 5GW module rating, by our arithmetic. T1’s release says the modules are expected to use a blend of imported and domestic cells.
The new deals of more than 1.58GW are roughly two-fifths of the more than 4GW now under contract for 2027, by our arithmetic; both figures are lower bounds. From the December 2025 construction start to first cells in Q1 2027 is about 13 to 15 months, also by our arithmetic.
Where This Sits in the Power Story
Power supply has run through our coverage of the AI buildout. On 30 October we reported Chevron’s 2.67-gigawatt Kilby gas plant for a Microsoft data centre in West Texas, as Texas Governor Greg Abbott has asked state regulators to pause data-centre permits until ERCOT completes its review. Cushman & Wakefield figures published by British Progress put US data-centre capacity at 103 GW built or planned.
Module gigawatts measure manufacturing output, not power-plant capacity or data-centre load, so these figures are not comparable or additive.
The Structural Read
As we read the release, most of T1’s 2027 module output is already under contract before the first cells from its Austin fab are due in Q1 2027, with more than 4GW contracted against a 5GW plant rating.
As we read the figures, the first 2.1GW phase of cells equals 42 percent of the 5GW module rating by our arithmetic. Separately, T1 says its modules are expected to use a blend of imported and domestic cells; the release does not link the two.
As we read the CEO’s quote, T1 is pitching its modules at AI infrastructure and the grid, while the release itself names Avantus subsidiaries as buyers and does not say whether any modules will power data centres.

Three Implications
FOR T1 ENERGY The release says T1 expects to offer modules with greater than 60% domestic content in 2027.
FOR BUYERS The release says T1 offers integrated solutions that help clients optimize project schedules, financing, and returns.
FOR THE AI POWER BUILDOUT Our prior coverage reports Chevron’s 2.67-gigawatt Kilby gas plant for a Microsoft data centre and a Texas request to pause data-centre permits; module gigawatts and plant gigawatts measure different things.
The framework says “The structural bottleneck isn’t computing, it’s electrons.”
As we read it, T1’s contracted module output sits on the supply side of that bottleneck. The framework was published in December 2025 and does not discuss T1 Energy, Avantus or solar module contracts.
What Is Not Established
The release does not give the prices, the full list of buyers, the split of the 1.58GW across 2027 and 2028, or how much of the more than 4GW comes from earlier contracts. It does not say whether any of the modules are destined for projects serving data centres. We have not seen a regulatory filing for the deals.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
T1 Energy says it has signed more than 1.58GW of new solar module offtake deals, including with Avantus subsidiaries, for delivery in 2027 and 2028 from its Dallas factory, and that more than 4GW of its 2027 manufacturing capacity is now under contract.
A note on sourcing. Company figures and quotes come from T1 Energy’s 30 October 2026 press release. Kilby, Texas permit and US capacity figures come from our earlier coverage. Figures labelled our arithmetic are our own calculations.
