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

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-...
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?)

Of course XAI is this article we’re all commenting on but here’s an older one: https://www.politico.com/news/2025/05/06/elon-musk-xai-memph...
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.
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.
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.

Consolidating down lots of small generators to bigger ones might the idea here?
I expect they are muffled. They are not jet engines.
Its about exerting power by willfully defying law. "Catch me if you financially can."
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.

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.
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.

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.

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.

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.

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.
