Is That New Data Center an AI Power Hog or a Mild One? Read the Filing

Updated October 7, 2026

A notice lands in your mailbox: a data center is coming, there's a vote, and the room is already split. One neighbor swears it's a quiet box of hard drives nobody will ever notice. The other says it'll chew through the grid and land on your power bill. So here's the short version — you can usually tell which one is actually coming before the vote, and the giveaway isn't the word 'AI.' It's the power number buried on page whatever of the application.

Skip the word 'AI' and go straight to the megawatts

The first thing I did was go looking for 'AI' in the paperwork. Waste of time. These projects get filed under bland shell-company names, called a 'data center,' and left at that. The word you want might not be in there at all.

So what actually sorts a quiet one from a monster? The amount of power it's asking for, written in megawatts. A small facility asks for a couple of megawatts. A plain cloud-storage building might want ten. An AI campus asks for hundreds — and some are now going to grid operators asking for a full gigawatt, which is roughly what one nuclear reactor puts out, or about enough to run a mid-sized city on its own.

That's the move: open the application, find the requested electric load, and read that number first. It tells you more in five seconds than the whole glossy cover letter does.

The cooling plans rat it out

Why does the power number carry so much weight? Because of what's sitting in the racks. A rack full of old-school drives and regular processors sips something under ten kilowatts. A rack packed with the Nvidia chips that run AI can pull fifty, a hundred, or more. A single AI rack can draw more power than a city block of window air conditioners running flat out in July.

And all that power turns into heat. You can blow air across ten kilowatts with fans. You cannot air-cool a hundred. So the hungry buildings have to run liquid right over the chips, and that shows up in the drawings — cooling loops, pipes, cooling towers, and a water-use figure that isn't small. If the plans talk liquid cooling and a serious water draw, you're looking at the AI kind. If it's just fans and rooftop air handlers, it's probably the mild one.

The cover page can be vague. The plumbing can't.

Follow the power back to where it comes from

One more place to look: where's the electricity coming from. A mild center just plugs into the grid that's already there and calls it a day. The hungry kind needs so much power, so fast, that the grid can't keep up — in some regions the line to connect now runs five to seven years.

So the big AI developers are building their own power plants on the property, behind the meter. Gas turbines. Fuel cells. Sometimes a side deal for a slice of a nuclear plant. If the application mentions a brand-new substation, on-site generation, or gas turbines, that's the fingerprint of a very large load — nobody bolts a power plant to a building full of hard drives.

And this is the part that ends up on your bill. When the utility has to beef up the grid to feed one of these, that cost usually gets spread across everybody's rates, not just the company's. The profit stays private; the wire gets paid for by the whole town. That's the thing that packed those town-hall meetings people keep posting about.

What a filing can still hide — and where to dig deeper

I'll be straight about the limits. A filing can bury a lot. The company name tells you nothing. A 'phased' project can start mild and balloon later. And numbers listed as 'up to' leave the developer room to grow into the big version after you've already voted.

So don't read the power, the cooling, and the generation one at a time — read them as a set, and if they point in different directions, trust the biggest one. Then ask your board to make the developer state the maximum buildout out loud, on the record, before the vote. The quiet ones have no problem saying a small number.

Common questions

Does the application have to say it's for AI?

No. Most get filed under a plain 'data center' label and a shell-company name, and some never mention AI at all. That's why the power request, the cooling type, and the water draw matter more than any wording on the cover page — the specs give it away even when the branding won't.

Will a data center near me raise my electric bill?

It can, and that's the fight in most towns. When a utility upgrades the grid to feed a large data center, that cost often gets spread across everyone's rates rather than charged only to the company. A small facility is unlikely to move your bill; a hundreds-of-megawatts AI campus is a different story. Ask the board directly who's paying for the grid upgrades.

How many jobs does a data center actually bring?

Usually a big construction crew for a year or two, then a small permanent staff to keep it running. These buildings are designed to run on very few people. If a pitch leans hard on 'jobs,' it's fair to ask how many are permanent versus temporary — the answer is often smaller than it sounds.

What does the water number tell me?

A lot. The power-hungry AI buildings run liquid cooling and can list a serious annual water draw, sometimes with cooling towers that lose water to evaporation. A modest water figure and air-only cooling usually points to the milder, lower-power kind. If the water line is blank or vague, push for a real number before the vote.

Is a 2-megawatt data center really that different from a 500-megawatt one?

Completely different animals for your town. A couple of megawatts is about a big-box store's worth of load. Hundreds of megawatts is city-scale — it can require new substations, its own on-site power plant, and grid upgrades that touch everyone's rates. Same two words on the application, wildly different thing showing up down the road.
