Today on Concrete Compute: has the backlash against data centers finally gotten scary enough to slow the buildout down — or is the industry still telling itself it's nothing? Before that, in the headlines: Microsoft and a major data center developer take their power fights to federal regulators, the US quietly outbuilds China on gas turbines for AI, and a fusion startup says its demonstration reactor is eighty percent built. Welcome back to Concrete Compute, your daily brief on the AI infrastructure buildout. It's Tuesday, August 25th, 2026. Let's get into it. And if you think the politics of this industry have settled down, today's main story is going to change your mind.

First up: two live fights at FERC — that's the Federal Energy Regulatory Commission, the referee for interstate power markets — and they both boil down to the same question: who pays for the grid upgrades a data center needs? In Wisconsin, Microsoft is objecting to agreements filed by American Transmission Company for its Mount Pleasant data center expansion, saying those agreements were negotiated between two affiliated utilities without Microsoft at the table, and that they leave a gap where regular ratepayers could end up covering the cost, or even paying twice. Microsoft, which has signed the White House's Ratepayer Protection Pledge, wants FERC to force a settlement conference. On the other side, ATC and its affiliate WEPCo contend their agreements are directly responsive to FERC's own concerns about cost shifting, and the Wisconsin Public Service Commission has taken something like a middle position, telling FERC the agreements are an improvement over past practice but still, in the commission's words, far from fully responsive to what FERC asked for. Meanwhile in Illinois, PowerHouse Hillwood — the joint venture behind a planned twenty-billion-dollar, 1.8-gigawatt data center campus in Joliet — is accusing ComEd of using what it calls monopoly power to cancel a transmission security agreement for that project. PowerHouse Hillwood's argument is pointed: FERC already has rules preventing utilities from playing anti-competitive games with power plant interconnections, but no equivalent rules exist yet for giant data center loads, and it wants the commission to close that gap before ComEd's cancellation takes effect. Worth remembering: that Joliet number is the developer's announced project size, not a built campus, and its power deal is now genuinely contested, not settled. Both disputes land right after FERC itself found in June that grid operators' large-load interconnection rules may be inadequate — so this is the same fight over who bears grid costs, just showing up in two different states, with two different utilities, at the same time.

Zoom out to the whole country for a second: a new analysis from Global Energy Monitor finds the US has roughly two hundred fifty-two gigawatts of gas-fired power capacity in development, versus about a hundred fifty-three gigawatts for China — that's roughly one-and-two-thirds times as much, not double, but still a clear lead, and about a third of that US gas power is planned to sit right on-site at data centers. That tracks with separate reporting from the International Energy Agency, which found US investment in fossil-fueled power plants is expected to overtake China's in 2026, driven by exactly this AI-fueled push for new gas plants. If all the currently planned US gas projects get finished, they would produce twelve-point-one billion tonnes of carbon dioxide over their lifetimes — that's double current annual emissions from every source in the country combined. Here's the honest caveat, though: these are development-stage numbers, a pipeline of announced and planned projects, not steel already in the ground. A lot of that gas capacity may never actually get built if AI demand growth cools off — and that's exactly the kind of stranded-asset risk this show keeps flagging on gigawatt announcements generally.

On the other end of the energy spectrum, Commonwealth Fusion Systems has closed a billion-dollar funding round, bringing its total raised to four billion dollars, aimed at finishing its SPARC demonstration reactor in Massachusetts. CEO Bob Mumgaard says the machine is now, in his words, about eighty percent complete, with the company targeting a net energy gain demonstration in 2027. The investor list mostly stays anonymous — pension funds, sovereign wealth funds, industrial corporations — but Google and the energy company ENI let their names be used, and both already have offtake agreements lined up for Commonwealth's planned commercial plant in Virginia, where the company has also applied to connect to the PJM grid. As @CFS_energy put it on X, fusion, in the company's own words, is largely unconstrained — no intermittency like renewables, no geopolitical baggage like fission, no resource limits like fossil fuels — which is exactly the sales pitch an AI industry hungry for firm, round-the-clock power wants to hear. Here's the honest framing, though: this money finishes a demonstration reactor, not a power plant, and fusion has a long history industry-wide of timelines that slip. Still, the fact that risk-averse institutional money keeps showing up for a technology that's still proving basic physics tells you something about how badly the AI buildout wants an answer to the power problem that doesn't involve burning gas.

One more quick one before we get to today's main story — and I want to flag upfront that this comes from a single X post, not a filing or a press release. The account @FrontierLedger, an investor and futurist account on X, reports that LS Electric expanded a US contract to supply high-voltage power equipment for an unnamed North American hyperscaler data center from seventy-point-four million dollars to a hundred sixty-five-point-seven million dollars — a hundred seventeen percent increase — in under three months, with delivery targeted for January 2027. We haven't independently confirmed those figures, and there's no named customer or filing behind them yet. But if it holds up, it's a nice small window into something we talk about a lot on this show: the electrical spine underneath a data center — the transformers, switchgear, and medium-voltage distribution that actually turn grid power into usable rack power — keeps getting scoped up mid-build, which tells you the original plans for these campuses were drawn too small the first time around.

Our main story today: the industry's reckoning with its own backlash — call it the question of whether the politics finally caught up with the megawatts. Politico's reporting frames this as a genuine moment of anxiety inside the AI industry, and the headline detail is a quote from an unnamed AI industry advocate who told the outlet this is an, quote, 'oh shit' moment. That phrase alone is a hook, but the substance behind it is real: Politico ties a wave of bipartisan moratorium pushes and cost-recovery fights directly to voter anger over power bills, water use, and land impacts — anger that, just months ago, was mostly associated with progressive figures like Senator Bernie Sanders, and is now showing up across the political spectrum. And Politico points to two governor's races as evidence the mood has teeth: Democrats Abigail Spanberger in Virginia and Mikie Sherrill in New Jersey both won races where forcing data center operators to pay their own grid costs upfront was part of the pitch to voters. That's Politico's framing of those results, worth saying clearly — it's their editorial read on why voters responded, not a poll the show ran itself. Separately, NPR's reporting on the same trend found that protesters in Virginia, Pennsylvania, North Carolina and other states have already shut down proposed data center sites, and one town in Wisconsin is trying to recall its own mayor over a data center approval. So how does the industry itself sound right now? Split, and not quietly. Even inside OpenAI, the message discipline is cracking a little — at a Politico forum this month, the company's VP for global policy, Ann O'Leary, acknowledged, quote, 'we have real work to do' on public concerns about data centers, while still calling the technology's promise 'incredible' and 'inspiring.' That's a company executive, in the room, conceding the gap between the industry's pitch and what communities are actually feeling on the ground.

Here's where I want to slow down and actually stack the voices on this, because it's genuinely a live argument inside the industry. That's not hedge-y language — that's someone inside the industry telling the rest of the industry it's misjudging its own exposure. And on the other side of that same quote sits an unnamed industry counterpart, described by Politico as dismissing the whole thing as nothing. So you've got two camps inside the same tent: one that thinks this is a five-alarm fire, and one that thinks it's noise. My read: the fire camp has the better evidence right now, because this isn't just online grumbling — it's showing up in actual election outcomes and actual moratorium pushes, and Politico's own reporting says this behavior, once confined to progressive outliers, is now bipartisan. That's a real shift in who's willing to run against a data center in a general election, not just at a zoning board meeting. I want to be careful here, because the skeptic case matters too — Politico's piece is built substantially on anonymous industry sourcing and its own framing of why Spanberger and Sherrill won, not a docket number or a passed moratorium bill with a bill number attached. Nobody in this reporting points to a single state that has actually halted construction outright, and it's worth being honest that a trend piece about mood is a different animal than a piece about a specific regulatory outcome. So what would move this from mood to hard outcome? A state passing an actual moratorium with teeth, not just introducing one — and a hyperscaler publicly walking away from a site because of local opposition, not just quietly rewriting its community benefits deal after the fact. Until one of those happens, what we have is rising political risk, not a confirmed construction slowdown. And I'll say this plainly, because it's my own standing view: the companies spending the most on this buildout can afford to take the O'Learys of the world seriously before an election forces them to — that's my standard, and it applies the same whether it's OpenAI, Microsoft, or anyone else writing nine-figure checks for a campus. On the hype-to-substance scale, I'm putting this one at a six. The anxiety is real and the electoral evidence is genuinely suggestive, but the piece is built on anonymous quotes and Politico's own causal read of two governors' races — not a moratorium that's actually stopped a shovel yet.

If this backlash keeps compounding the way Virginia and New Jersey suggest it might, the companies writing the checks are the ones who eat the political cost first — and the communities hosting these campuses are the ones deciding, county by county, whether they get a real seat at the table or just another press release. We'll dig into the next state that puts an actual moratorium bill up for a vote. If you're finding this show useful for sorting the real signals from the press releases, the best thing you can do is follow it wherever you're listening, so today's episode isn't the last one that finds you. This has been Concrete Compute, an AI-voiced podcast, created and built by a real human using today's cutting-edge technology. Nothing you heard on this show is financial advice. I'm Brian Lampert, and I'll catch you all tomorrow — take care!
