Most solar panels are imported from China which now has the ability to manufacture over a terawatt (1,000 gigawatts) of solar modules every year — roughly equal to the entire installed base of generation in the US inclusive from every energy source.

America makes less than 1/20 of that amount and even less when it comes to the more difficult task of manufacturing cells.

But Texas is known for manufacturing and T1 — short for Type 1 civilization — is building solar manufacturing in Texas that could change the game.

This is about energy abundance that is reliable, local, and affordable.

As T1 CEO Daniel Barcelo told me:

“I’ve been working in oil and gas and I am an old oil and gas guy who has run oil and gas companies globally. At the end of the day, it’s really about providing the lowest cost energy in whatever form it is and delivering that energy at a cost-competitive basis to the customer. That drives the philosophy at T1.”

T1’s plan is straightforward and ambitious: a multi-site Texas footprint that connects a domestic solar manufacturing chain from materials to finished modules. The company has a module assembly plant in Wilmer in the Dallas area, and is developing cell manufacturing in Rockdale in Central Texas. Upstream, they’ve lined up domestic polysilicon supply from Corning to feed those lines.

While T1 scales up supply, demand for power is surging.

Texas electricity use is rising rapidly, driven mostly by oil and gas demand, cryptocurrency mining, industrial electrification, and data centers. Texas demand is up 23% in the last four years; most of that new demand is being met by solar power.

When more of the equipment is made here, projects move faster and carry less supply-chain risk. And solar can be scaled very quickly to meet near-term needs.

“AI needs energy. Data centers need energy. They need it now. It’s great to build nuclear plants in 2030. That’s awesome. But the world’s not waiting. And the big tech companies are not waiting. And right now, solar and storage can deliver it.”

This is not either-or. Texas has long succeeded by adding the next tool that works. Solar plus storage are tools for growth and we should use them.

Domestic manufacturing creates jobs and strengthens our energy security and global competitiveness.

Texas has never waited for someone else to build our future. If companies like T1 can stand up the full stack here, we get more than panels.

We get speed, security, control, and the ability to match ERCOT’s needs with Texas-made solutions.

Doug Lewin (00:05 .25)

Welcome to the Energy Capital Podcast. I’m your host, Doug Lewin. My guest this week was Daniel Barcelo, the CEO and chairman of the board of T1 Energy. We talked about how they got their name in this episode. I think you’ll enjoy that. This is a fascinating company, headquartered in Texas. They are building out a full end-to-end manufacturing of solar in Texas. They started with the acquisition of a manufacturing plant, five gigawatts of solar module assembly in Wilmer, Texas, just south of Dallas. They are currently building in Rockdale, Texas, about 60 miles north of Austin, a cell manufacturing facility. So obviously cells are much more complicated to manufacture, much more complex than the module manufacturing. They are also in partnership with Owens Corning to get the raw materials actually sourced here in America. So that when they are done with that process in a year or two, they will have end-to-end American solar manufacturing. So we talked a lot about the potential for American manufacturing of solar, how big it is now, what its potential is to maybe counterbalance China, which is really dominating electricity supply chains throughout a whole number of different components, including all parts of the solar supply chain. They’re dominating that globally. Can America be a counterbalance? One of the things I really enjoyed about this conversation is Daniel has a great perspective, having worked in oil and gas for much of his career, really at the broad spectrum of energy. So I think that really comes through in the interview. I think you’re going to enjoy that.
