A Rocket Company Is Building Its Own Power Grid

A one-page city notice told the story.

On November 6, Starbase posted a public hearing notice. SpaceX wants to build a gas-fired power plant and an AI supercomputer on 444 acres near Boca Chica.

The price tag… about $24 billion for the first phase.

That's not a typo.

SpaceX would install up to 35 gas turbines on the site. They'd produce roughly 748 megawatts of power — enough to light half a million homes.

But SpaceX doesn't want to light homes. It wants to power chips.

Let me explain…

Two weeks ago, SpaceX signed a $40 billion GPU lease with Apollo Global. Apollo buys Nvidia's newest chips. SpaceX rents them.

But chips need a building. And they need a lot of watts.

This $24 billion campus is that building.

Here's the twist.

Most data centers plug into the local power grid. SpaceX won't.

It plans to burn natural gas on its own land and make its own power.

The industry calls this "behind the meter." You skip the grid, the line, the utility.

Why bother?

Because grid access is the bottleneck.

Big tech firms wait years for hookups. SpaceX already owns the land. And natural gas is cheap in South Texas.

There's a precedent too.

xAI — SpaceX's AI arm — runs the Colossus supercomputer in Memphis. That site pulls about 150 megawatts from the local grid.

The backlash was fierce.

Starbase would produce five times that power on-site. No grid strain. No angry neighbors.

Now, I know what you're thinking.

Why does a rocket company need this much compute?

Two answers. xAI trains Grok, its chatbot — and training big AI models eats vast power. SpaceX also uses machine learning across Starlink, rocket landing, and flight ops.

More GPUs make all of those faster.

But here's what grabbed me.

A $40 billion chip lease. A $24 billion campus. That's $64 billion aimed at AI.

From a company that IPO'd at $135 a share five months ago.

SpaceX isn't just a launch company anymore. It's an energy-and-compute company that happens to launch rockets.

The Starbase City Commission votes on the tax abatement December 9. And since Starbase is, in many ways, a company town — approval seems likely.

Watch that date.

It's not Tesla. It's not SpaceX.

It's the little-known company Elon pays every time he builds anything. Every Tesla. Every Starlink dish. Every AI satellite.

Now he's filed to launch 1,000,000 satellites.

That could mean a 100X bigger bill.

The city notice says SpaceX will "construct, own, and operate" a gas-fired power plant and super-compute facility. It does not give a turbine count or a power figure. It also does not say whether the site will connect to the state grid. The 35 turbines and 748 megawatts come from an air-permit application to the Texas Commission on Environmental Quality, according to Politico. Those turbines are described as mobile. And the $24 billion covers only the initial phases… Watch the state permit.

The Memphis site began with only 8 megawatts of grid power, so xAI ran temporary gas turbines there. Environmental groups said some turbines lacked the right permits, and their "portable" label was central to that fight. SpaceX then built a plant across the state line in Southaven, Mississippi, permitted for 41 turbines and about 1.2 gigawatts. SpaceX's S-1 says Colossus 2 can run entirely on a self-built gas plant. So Starbase follows a path SpaceX already took… Watch whether the turbines get permits before they run.

The Dec. 9 decision is local. Politico reports that two of the three commissioners who will consider the incentives are SpaceX executives. The tract also sits just outside a data-center moratorium that took effect in neighboring Brownsville last week, according to Teslarati. And the notice does not say how large the tax break is or how long it would last. Watch the terms of the Dec. 9 agreements.

Watch the hearing and the permit.

On Dec. 9 at 7 p.m., the Starbase City Commission holds a public hearing on a property tax abatement and an economic development agreement. Sources say commissioners will consider the deals there. The notice does not say how big the abatement is.

The air permit is the other clock. Local approval gives a tax break. The state permit decides whether the turbines can run. SpaceX has applied for permits covering the turbines, according to Politico, but no decision has been reported.

Then there is scale. The notice says the project "may be constructed over multiple phases and include future expansions." So $24 billion is where it starts…

And there is the chip side. The $40 billion Apollo-backed GPU lease is a binding commitment, expected to close before year-end. No source we found says where those chips will sit. Watch for any link between the lease and the Starbase site.

So Dec. 9 is the first date. It will not be the last.

Let's keep this simple.

A house can get power two ways. It can plug into the utility's wires. Or it can run a generator in the backyard.

Plugging in means the utility owns the power plant. You pay for what you use, and you wait until the utility connects you. For a huge data center, that wait can run to years.

A backyard generator skips the wait. The power never passes through the utility's meter. That is what "behind the meter" means.

But you pick up the jobs the utility used to do. You buy the fuel. You keep the machines running. And you answer to the rules on air emissions.

At Starbase, the machines would be gas turbines, and the scale is huge. About 35 of them, for roughly 748 megawatts. That is why a state air permit sits at the center of the plan.

It is also why Memphis turned into a fight. The turbines there were called portable, and the permit rules for portable machines became the argument…

So the trade is speed for responsibility. You skip the line. You own the smokestack.

Follow who carries the fuel bill and the permit, and you see who really owns the risk.
