Who Pays When the Machines Outrun the Rules?

Welcome back to Concrete Compute, your daily brief on the AI infrastructure buildout. It's Saturday, September 12th, 2026 — time for our weekly recap, where we step back and look at the shape of the whole week instead of just one day's headlines. And this week had a real shape to it. On paper, the buildout kept accelerating — more capital committed, more concrete poured, bigger targets set. But everywhere those numbers touched the ground, the politics got messier. A federal court pushed back on Washington. Pennsylvania regulators opened a formal review of who pays the bill. And a New Jersey data center got caught, allegedly, running dozens of generators it never got permission for. This is the week accountability started catching up to speed. Let's get into it.

Let's start with the number that sets the scale for everything else this week. Anthropic disclosed it has signed roughly five hundred seventeen billion dollars in compute agreements over the past eleven months. That figure dwarfs almost any single data center project you'll hear about — it's the backdrop for every community fight we're about to cover. Now, an important caveat: signed agreements aren't delivered capacity. This is capital committed over time, not money already spent building anything. How much of that five hundred seventeen billion is already showing up as physical construction, versus contracts dated years out? Nobody's published that breakdown yet, and that gap matters — because everything downstream, from grid strain to local permitting fights, depends on how fast that paper turns into steel.

Sticking with scale for a second: US data center construction spending hit a record annualized rate of over seventy-five billion dollars, a figure the Census Bureau released for July, and one that first got wide attention in early September — so this is a number that's been settling in for a week or so rather than something brand new this week. Either way, it's the physical footprint behind all the fights we're covering — the permitting disputes, the water arguments, the rate cases. Annualized numbers can swing month to month, so whether this holds through year-end is worth watching, but for now it's the clearest sign yet that the capital chasing compute is actually turning into cranes and concrete, not just spreadsheets.

And the target all that capital is aimed at just got bigger. Bloomberg reported this week that Microsoft is planning thirty-eight gigawatts of data center capacity by twenty thirty-two — one of the largest single-company capacity targets disclosed all year. Worth being precise here: that's a six-year planning target, not built or contracted capacity today. How much of that thirty-eight gigawatts already has site control or power contracts locked in versus just being a number on a slide? That's the question that separates a real buildout plan from a press release with a nice round figure attached.

Now the politics. President Trump argued this week that communities blocking data centers risk poverty, crime, and squalor — his words for the economic decline he says follows when towns say no. At the same time, NPR and NBC reporting found voters in key midterm districts telling both parties they don't want new data centers built near them. I'm not going to adjudicate which side is right, because both are political claims about local economic outcomes, not settled facts. But here's what's real: this is now a genuine midterm fault line, and it's cutting across party lines in both directions — a governor who wants the jobs, a homeowner who doesn't want the noise or the power bill. Evaluate the deal, not the team.

Now for a story that actually tests one of those claims in court. The DC Circuit Court of Appeals vacated the Trump administration's order forcing Consumers Energy's J.H. Campbell coal plant in Michigan to keep running past its planned retirement. That plant had been kept online through six straight Department of Energy emergency orders since May of last year — DOE's stated justification tied partly to regional reliability concerns amid surging demand, the same demand story we've been tracking all week. The court found that reasoning didn't clear the legal bar for a genuine emergency under the Federal Power Act, and vacated the order outright. This is the kind of ruling that could ripple well beyond one Michigan plant — DOE has issued similar emergency orders to keep other aging plants open elsewhere, citing the same data-center-driven demand growth, and this precedent calls that whole approach into question. It's not the final word, though — this is one circuit court, DOE could appeal, and it's not clear whether the agency tries another emergency order or a different legal path to keep Campbell running. My read: this is the first real judicial check on the idea that AI demand alone justifies overriding a utility's own retirement plan, and it's something I'll be watching as more of these emergency orders come up for renewal.

Here's the story that stopped me cold this week. An investigation by Floodlight, reported by The Cool Down, found that the DataOne data center campus in Vineland, New Jersey — the site tied to a seventeen billion dollar Nebius-Microsoft compute deal — has been running at least forty-five of its sixty-two gas generators despite the state having issued no air permits for any of them. A former EPA air enforcement chief told the investigation the operation appears to violate federal law. The site sits about a mile from two schools, and residents are already suing over the noise. Now, DataOne says it remains committed to permitting requirements, but hasn't actually addressed the specific findings, and New Jersey's DEP hasn't made a full compliance determination yet — so this is a serious allegation from an investigation, not a completed regulatory finding. But here's my standard, and I apply it to every company doing this at scale: anyone attached to a seventeen billion dollar compute deal can afford to get the paperwork done before the generators start running, not after. Will NJDEP issue an enforcement action, and does any of this touch the timeline of the underlying Microsoft-Nebius deal? Those are the two questions I want answered next.

Now, the flip side of the power-and-grid-strain story. Canary Media reviewed satellite imagery and found that xAI — now part of SpaceX — has quietly installed seven hundred twenty Tesla Megapack battery containers at its Colossus 2 site in Memphis, roughly two-point-eight gigawatt-hours of storage by Canary's estimate. That would potentially make it the largest grid battery in the country, and it appears to have gone up with essentially none of the community outreach or utility-contracting process a project that size would normally require. To be clear, the exact size here is a satellite-image estimate, not a confirmed disclosed figure — xAI hasn't detailed the project publicly. But if it's real at that scale, it likely reduces reliance on the site's already-controversial gas turbines, even as it raises the same oversight question as the New Jersey story: is this project getting built faster than anyone outside the company can actually see what's happening? Is this battery providing any grid services to Memphis, or is it purely backup for the site itself? That's the difference between infrastructure that helps the neighbors and infrastructure that just quietly serves the machine.

This is the story I think matters most for the long run, even though it made the fewest headlines. The Pennsylvania Public Utility Commission voted five to zero this week to launch a Ratemaking Working Group — examining utility return-on-equity practices, rate-case transparency, and curtailment rules as data center electricity demand grows. It follows Governor Shapiro's executive order in August on data centers' impact on residents. Now, this is the opening of a review process, not a rate ruling — there's a technical conference on cost allocation scheduled for this fall, and the actual report timeline stretches into twenty twenty-seven. My prior on this show has always been that the party creating the incremental cost should pay it — dedicated infrastructure and stranded-asset risk belong on the developer, not the neighbors. Pennsylvania going after utility ROE and rate-case mechanics, instead of reaching for a moratorium, is exactly the kind of ratepayer-protection-plus-buildout approach I'd want to see more states try. What would actually change on a typical bill is still unknown — that's the number this working group needs to produce.

Last one, and it's a reminder that data centers aren't just cost centers for the companies building them — they're becoming revenue engines too. SpaceX's CFO Bret Johnsen disclosed at a Goldman Sachs conference this week that the company signed a new hosting deal worth one-point-eleven billion dollars a month — about thirteen-point-three billion dollars annualized — starting in December, with the customer unnamed. That brings SpaceX's total annualized compute-leasing revenue to roughly forty-one-point-one billion dollars. SpaceX renting out its own Colossus capacity is turning into a real second business line, right alongside Anthropic's compute-buying spree from earlier this week — everybody in this industry is figuring out how to be both tenant and landlord at once. Worth noting: this is disclosed via conference remarks, not a filed contract with a named counterparty, and it comes amid separate reporting of cooling and power problems at SpaceX's Tennessee and Mississippi sites. Who the mystery customer is, and whether SpaceX's own site reliability holds up as this scales — those are the two threads I'd chase next.

That's the week — a scale that keeps getting bigger, and an accountability question that's finally catching up with it.
