XAI data center gets air permit to run 15 turbines, but imaging shows 24 on site

pyrale•4h ago
I know right, why do people care so much about air pollution? It’s not like it kills anyone, right? What’s smog anyway?
rbanffy•4h ago
Besides that, who would imagine Elon Musk, of all people, would be breaking laws?
spectre9•4h ago

msgodel•3h ago
I live somewhere that's never had a smog problem so I'm not super familiar with it but do gas turbines actually generate smog? I feel like of all the classes of heat engines they'd produce the fewest particulates. Is this actually a problem out there in the West?
perihelions•3h ago
Burning of methane (natural gas) produces oxides of nitrogen (NOx) (several types), which are a major driver of smog. See, as a starting point,

https://en.wikipedia.org/wiki/NOx

While natural gas is cleaner than coal in some obvious ways (i.e., no particulate solids), it has a specific problem with NOx, because of the super high temperatures inside internal-combustion gas turbines. The upside is higher thermodynamic efficiency (highest of any thermal source); the downside is, this.

msgodel•3h ago
Methane has no Nitrogen in it. All of that would have to come from the air. It's famously very very hard to react Nitrogen that way, I'd be surprised if gas turbines produced it in noticeable quantities.

EDIT: didn't see your edit until now. Heh it shouldn't be too hard to scrub out if it were really a problem. That seems like a better way to handle it than this weird exemption process that seems to be in place now.

rini17•2h ago
All diesels produce enough of NOx that catalytic reduction is needed.
msgodel•2h ago
Diesel has a lot of impurities. Methane is just one molecule.
rini17•2h ago
If it were so easy just better refine the fuel why would Europeans bother to add these converters and adblue injectors? No it's not impurities, but high pressure/temperature combustion. The higher the more efficient and more NOx comes out.
msgodel•2h ago
Europe does all kinds of things, basing your understanding of chemistry around what a state does rather than the other way around is literally insane.
audiofish•2h ago
There are multiple NOx sources during combustion.

Fuel NOx is only one of them, which you quite rightly point out is not dominant in methane combustion due to the rarity of nitrogen in the fuel.

The dominant source in methane combustion is thermal NOx, which forms due to the extreme temperature of the combustion, causing atmospheric nitrogen to decompose and react with atmospheric oxygen.

perihelions•2h ago
> "Heh it shouldn't be too hard to scrub out if it were really a problem."

The entire point of this dispute is that xAI could install scrubbers for these emissions, but chooses not too. The Ars Technica article discusses this at great length.

msgodel•2h ago
Oh I didn't realize that. Yeah they need to follow the law or build the thing somewhere else.
stephen_g•2h ago
Surprised? Gas turbines do produce large amounts of NOx, it’s been a huge effort over decades to bring it down in both aviation and stationary plants… (e.g. https://www.epa.gov/sites/default/files/2015-01/documents/05... )
pyrale•2h ago
It is not a problem if the plant respects regulation and industry standards... which in this particular case doesn’t seem to be a priority.

Many investors use imaging to see how many customers visit a store -- they count the cars in the parking lot at certain times of day.
davidguetta•2h ago
that's actually an interesting point. Like people using sat imaging on steel depot in australian to evaluate the demand
fuzzbazz•4h ago
Can't verify from the low quality photo in the article.

This [1] press release from the Southern Environmental Law Center hints to a possible reason - they may be migrating from small to bigger turbines:

> Aerial images obtained by SELC revealed 35 turbines at the site in March (...) while the company has removed some smaller-sized turbines, it has recently installed three larger turbines

From a different perspective: the fact US businesses can assemble massive power plants on demand, in weeks, is quite an illustration of the economic dominance of the country.
hnthrow90348765•3h ago
Too bad they're not smart enough to do anything useful with that capacity
smartmic•3h ago
If you mean the financial power to pay for such power plants, then I agree. But the technical capabilities to quickly provide stationary or mobile power plants can be purchased from a few large, international companies; noteworthy suppliers can be found in the USA, Europe and Asia. And they will build it for you in almost any country in the world, as I said, provided you pay accordingly. Of course, the delivery time of turbines is often a bottleneck, but this applies more to the very large ones than the smaller ones that should actually be installed here (and it also applies equally to all manufacturers).
ben_w•2h ago
16.48 MW each: https://www.shelbytnhealth.com/DocumentCenter/View/7174/0115...

They're big, by the standard of a domestic source such as a car, but they're not what I'd call "massive" in an economic dominance sense. About the size of a large shipping container, give or take, eyeballing from other photos that tell me which objects the turbines even are: https://www.capacitymedia.com/article/musks-xai-data-centre-...

perihelions•2h ago
It's a large power plant (400+ MW and rising), rapidly assembled from small, modular components. That's a remarkable thing from any point of view.

The other threads on this topic (powering AI hyperscalers) are usually about nuclear fission, which most of the large players are investing in. Those power plants often take 10+ years to build. One could imagine small reactor modules akin to these 16 MW shipping containers, built in factories and shipped on demand like these, to be assembled into a full power plant in weeks. If someone were to get that business model working, they'd dominate the industry. (Just how big of a premium did xAI pay their vendor, to have all this shipped halfway around the world on a priority schedule?)

blibble•2h ago
given musk's attitude to the waste management (just pump it into the lungs of the local population), god help us if he gets access to nuclear reactors

rsynnott•1h ago
There’s a reason this isn’t generally done for real power plants; these little turbines are pretty inefficient. This sort of thing is not uncommon for data centers and other things that need either a lot of backup power or a lot of temporary power, but it would not make for an economically viable power plant.
blackbear_•1h ago
Source for the timeline? Nowhere in the article is it said that the construction happened within weeks.
danpalmer•3h ago
Musk's playbook is to do the thing that he feels is obviously right, and figure out the consequences later, and because he's enough of a bully and rich enough, the consequences rarely end up being that big a deal. I believe it's ideological, and from that perspective have a hard time disagreeing with his motivations – I disagree with him, but think he's doing what makes sense to achieve his goals which he believes are good for the world.

He's done this with SpaceX many times over, bullying the FAA and the local council in Texas. He's done this with Tesla again and again with crash data and even selling products that don't exist to consumers. He's going to keep doing it until there are actual consequences because it's hard to say it's not a good business decision if you never actually have to pay for the issues you cause.

sReinwald•2h ago
You've nailed the pattern. And the regulatory environment actively enables it through what amounts to a pricing model for violations.

When the EPA or county eventually fines xAI for running unpermitted turbines for a year, it'll be what - a few hundred thousand? Maybe low millions if they're feeling particularly spicy? For a company chasing the AI gold rush with Musk's billions behind it, that's not a penalty - it's a rounding error. It's cheaper to violate now and pay later than to wait for permits while competitors build capacity.

And unfortunately, this isn't a bug in the regulatory system - it's the feature. When fines are pocket change relative to potential profits, "ask forgiveness not permission" becomes optimal strategy. The only things that actually change behavior are existential threats (criminal charges, shutdown orders) or catastrophic reputational damage - and Musk has proven immune to both.

Until penalties scale with company valuations or include mandatory shutdowns, this playbook will keep printing money. Memphis residents get respiratory disease, xAI gets compute capacity, and regulators get a check that wouldn't cover a week of Musk's jet fuel.

potato3732842•2h ago
The root problem here is that the regulatory environment has been (in bits and pieces over the years) set up to be a checkbox exercise for those on the inside and exclusionary toward new entrants. The rules and process of that side of things are not subject to serious oversight so they can be as exclusionary and rent-seekey as the lobbyists and the bureaucrats want, potentially preventing any new entrants.

Musk has, very rightly, realized that the punishment track is subject to far more political and public scrutiny than the approval track and that if you are doing things that people want like building cars and sending rockets into space the scrutiny will prevent them from doing anything to financially cripple your operation.

Ironically, this is playbook that's common at the complete opposite end of the economic activity spectrum where there literally isn't the money to comply. People run unlicensed businesses, do un-permitted work, violate minor regulations, etc, etc, all the time. And by the time anyone figures it out, if anyone ever figures it out, it's too late.

If it were truly ideological for him, wouldn't that roof be covered in solar panels and he'd be leading the charge on shifting this huge energy consumption in this emergent high-use use cases towards renewable resources?
mynti•1h ago
you are totally right which makes this so sad. a lot of regulations might be tedious but they have (most of the time) a good reason to exist. now the people around the data center will have to deal with terrible air quality so twitter users can ask about white genocide all day long

Somehow I doubt that he is personally involved in provisioning auxiliary power sources for a Tennessee datacenter.

Thermal imaging, displaying 24 active turbines would have been more relevant. The article contained one image, none of the alleged turbines were highlighted. As a layperson, I'm not sure what I am looking at here.

There has been reporting about this for months. I realize I'm just a pleb, but I really don't understand why a company with, essentially, limitless money, won't simply install the emissions reducing hardware and properly permit the turbines. Like a lot of what's going on around Elon/US politics, it seems like a meaningless fight and is only further torching reputations. Just do the obvious right thing and move on.
MisterTea•2h ago
> I realize I'm just a pleb, but I really don't understand why a company with, essentially, limitless money, won't simply install the emissions reducing hardware and properly permit the turbines.

Its about exerting power by willfully defying law. "Catch me if you financially can."

vorpalhex•26m ago
Read the article carefully.

They are allowed to run N turbines.. but have N+B turbines on the property.

They.. aren't breaking their permit. The article never says they are, it just sets things up for you to have that belief.

It looks like they are swapping turbines, thus the extras. They may also be hoping to get more approved.

These may also be properly emission reducing. The article never says they aren't - it only includes quotes from people saying they don't think they are with no evidence.

The news doesn't lie, but it gets as close as it can.

I am looking at that roof and thinking how much better it would look as one massive solar panel.
perihelions•2h ago
It'd have to be a solar farm 3 kilometers on each side to meet a 400 megawatt load (with battery storage). If you take the entire block xAI colossus is on—it's 1.2 by 1.6 km—cut down all those trees, raze the elementary school (the one being smogged right now—did anyone notice there was a school right next to it?)—that, times five, is what you'd actually need.

https://www.google.com/maps/search/xai+colossus

The end goal is 2,000 megawatts for this datacenter, so multiply that by five again.

This CEO founded a solar power company, and a battery-storage company as well—I'm very certain he considered the all-solar option carefully, and rejected it for actual technical reasons; not vibes.

blitzar•41m ago
> all-solar option

Who said it needed to be "all solar". Obvious anyone with a brain would have noticed it is dark at night and there would be no power production so "all solar" is litterally impossible.

tmaly•27m ago
That this is a thing makes me wonder if Elon opened a can of worms with this new political party. He is not making any friends challenging the established parties. They will show no regulatory mercy.
