So here's a thing about industrial policy: sometimes the government just says, "Hey, private sector, we'd really like you to build some stuff here," and then the private sector says, "Okay, but you're going to help, right?" And then they announce a bunch of deals. That's basically what happened this week.
The Department of the Interior under the Trump administration put out a statement saying it had "catalyzed" agreements worth more than $56 billion. These are, in the DOI's words, "private sector commitments that will create good-paying American jobs and secure critical energy supply chains." It's the kind of announcement that makes you wonder what "catalyzed" really means—did they just make some phone calls? Offer some permits?—but the dollar figure is certainly eye-catching.
And nestled within that $56 billion is a particularly shiny piece of news: Tesla Inc. (TSLA) and South Korea's LG Energy Solutions are teaming up to build a $4.3 billion battery plant. Specifically, they're expanding an existing partnership with a supply agreement to construct what they're calling an "LFP prismatic battery cell manufacturing facility." If you're not a battery engineer, just think of it as a very expensive, very important factory that makes the guts of energy storage systems.
This facility will be in Lansing, Michigan, and it's scheduled to kick off production in 2027. What will it make? Batteries for Tesla's Megapack 3 energy storage system, which itself is produced down in Houston, Texas. So it's a whole domestic supply chain story: Michigan makes the batteries, Texas assembles them into big storage units, and presumably someone somewhere is very happy about the jobs and the "secured" supply chain.
This isn't Tesla's only recent battery move. The company just signed a separate $2 billion agreement with another South Korean firm, Samsung SDI. That deal came on the heels of Tesla's energy storage business posting some impressive numbers, deploying a record 14.2 gigawatt-hours worth of batteries in the fourth quarter of 2025. When your storage business is growing that fast, you need a lot of batteries, and you probably don't want to rely on just one supplier. Hence: deals with LG and Samsung.
And it's not just about buying batteries from other people. Tesla is also working on the underlying technology. The company recently filed a patent detailing what it calls a breakthrough in battery chemistry. The patent describes a new solvent—dimethyl 2,5-dioxahexanedioate, or DMOHC, if you're into that sort of thing—and a new lithium salt. The claim is that this new chemistry can help lithium-ion batteries perform more efficiently under high voltage and high temperature conditions. In plain English: they're trying to make batteries that don't freak out when things get hot or the power gets cranked up. It's the kind of incremental but important R&D that keeps a company at the forefront.
On the market side, Tesla's stock saw minor movement. It declined 0.03% to $395.45 during overnight trading on Tuesday and dipped another 0.18% to $394.83 in pre-market trading. In the grand scheme of a multi-billion dollar manufacturing announcement, that's basically noise.
The bigger picture here is about building things in America—or at least getting companies to commit to building things in America. The DOI's $56 billion figure is a headline grabber, and the Tesla-LG plant is a concrete example of the kind of project they're talking about. It's a bet on the future of energy storage, a nod to supply chain security, and a very expensive real estate development in Michigan, all rolled into one.
