siting a data center in texas is a land question first

The conversation about data centers in Texas is a conversation about power. How many gigawatts, which grid, gas or nuclear, when. That is real. But read what the state has actually written down in the last year and a different picture shows up- the questions that decide whether a campus gets built are land questions. Who controls the site. Where the water comes from. What the neighbors hear and see at night. Who is paying for what.

Those are not engineering questions. They are the questions anyone who has walked a project through approvals already knows how to answer.

1. the power request now starts with a land document

SB 6, signed in 2025, rewrote how big loads connect to the ERCOT grid. It applies to new or expanded requests where the total load at one site crosses a threshold the Public Utility Commission sets- 75 megawatts, unless the commission decides a lower number is needed (Utilities Code 37.0561(c)).

Most of the coverage focused on the money and the off switch:

• a flat study fee of at least $100,000 for the first transmission screening study (37.0561(f))
• a financial commitment toward the transmission needed to serve the load, which can be security set per megawatt (37.0561(h))
• for loads connected after December 31, 2025, a way for the utility to curtail them during firm load shed (39.170(a))
• disclosure of on-site backup generation, which the grid operator can call on in an emergency (37.0561(e))

The line I keep coming back to is a quieter one. The standards must include a way for the customer to demonstrate site control- an ownership interest, a lease, or another legal interest the commission accepts (37.0561(g)).

That means the land deal is no longer something you finish after you know you can get power. It is part of asking for power. A speculative request on land nobody controls is exactly what the law is trying to filter out.

In September the PUC finished the rule that puts this into practice (16 TAC 25.194, order filed September 18, 2026), and it spells out what counts. One of three things, signed: a lease long enough to run at least five years past the date the load expects to hit its requested peak, a deed, or an option to buy or lease (an option to lease has to carry the same five-year term). You show it before your request goes into the grid study, and again at the final interconnection agreement- where an option no longer counts. By then you need the lease, the deed, or a signed purchase and sale agreement. The study fee landed at a flat $100,000.

So a handshake with a landowner does not get you in line anymore. Paper does.

If you're putting a site together, the lease is the first drawing now. Get five years past peak in writing before you spend a dollar on the building- otherwise someone else's paper gets in line ahead of yours.

2. the audit asks five things, and four of them are about the site

On August 3, 2026, the Governor directed the PUC and ERCOT to audit every data center moving through ERCOT's interconnection process, and said that the audit has to be finished before any data center project moves forward. Projects that do not comply "will be denied connection to the Texas grid." The release puts the queue at about 474 gigawatts of requests, with about 90 percent of the new requests from data centers.

Each project now has to show:

1. who is paying- every state and local tax incentive, grant or abatement, received or expected 2. whose power- projected annual and peak electricity use, and any on-site generation 3. whose water- projected annual and peak water use, the source of supply, and the cooling system (air-cooled, closed-loop or another water-efficient system) 4. what the neighbors get- noise, light, setbacks, traffic, emergency response and "other community protection measures" 5. who owns it- ownership and controlling interests

Read that list as a site planner and three of the five are a site plan and a narrative: the water story, the cooling choice, and a drawn answer for noise, light, setbacks and traffic. The incentive question is a land-and-community question too- an abatement is a deal with a local government, and the neighbors will hear about it.

None of this is a building design problem yet. It is a site problem.

3. outside city limits, nobody is zoning it

Plenty of these campuses are going where the land is: outside city limits, in a county. That matters more than people expect.

Zoning in Texas is a city power. Local Government Code 211.003 lets the governing body of a municipality regulate height, lot coverage, yards, density and the use of land. Counties do not get a general version of that. Chapter 231 of the same code gives counties zoning authority only in a list of specific places- Padre Island, the area around certain lakes, a few named areas.

So for a rural campus there is often no zoning hearing at all- the county still touches it through plats, floodplain permits or a tax abatement deal, but not through zoning. No board weighing setbacks, no ordinance telling you how far the substation sits from the property line. The community conversation that would normally happen at the city happens somewhere else- now partly inside a state audit that asks about setbacks, noise and light directly.

That cuts both ways. Less process up front. But the questions a zoning hearing would have forced you to answer early are still there, and a project that has not thought about them will meet them later, in public, at a worse time.

Inside city limits the answer can be no. On June 16, 2026, San Marcos amended the Land Use Matrix in its development code to prohibit data centers in all zoning districts- the amendment passed 4-3, inside a code rewrite (Ordinance 2026-08) that passed 7-0. Before that vote, data centers would have been allowed in Heavy Industrial only, with a conditional use permit from council.

Northeast of Austin, the registry shows the other direction. On September 30 Hutto Data Center Campus, LLC registered Skybox Hutto 4 with TDLR- a one-story data center of about 844,300 square feet plus an office, core and shell with a future use as a data center, an owner's estimate of $550 million.

Same region, same year- one city wrote data centers out of its code, and one county past Austin, in Williamson County, a $550 million shell is headed into state review. A registration is not an approval, but which side of a city line the land sits on, and which city, is now part of the site question.

What to do about it: build the site packet before the interconnection request, not after. Proof of site control. A water source you can name and a cooling choice that fits it. A site plan that draws the setbacks, the noise and light answer and the traffic route. An honest power story. It is the same packet the audit is asking for, and it is cheap to make while the land is still cheap to walk away from.

4. who's building them

Part of the land question is who's asking it. A lot of the people chasing these sites were building something else a year ago.

So many people are jumping onto this sector right now, because everything else is in the tanks. Especially with an overbuilt Austin- everybody's trying to figure out, oh crap, I built my pro forma off of 2022 numbers and that's not working anymore. Be it tariffs, or be it you just can't charge that much for it.

And some of the local guys aren't just doing small stuff anymore. They're growing with the times and going all in when the data sector booms. Not 20% year over year- more like 100% over two years, and trying to figure out how to scale efficiently. People are moving from different sectors into the booming one. Everybody's kind of folding over each other.

Ten years of apartments teaches you land, entitlements and neighbors. It doesn't teach you a five-year lease past peak demand or a water story the state is going to audit. That gap is where the site packet earns its keep.

5. what i am watching: the nuclear part

I think the folks betting on nuclear are right in the long run. But a reactor needs what every campus needs- a site somebody controls, water, and neighbors who'll live with it. Plant-side deals have to be noticed to ERCOT now, not just shaken on. Land near existing generation just got more interesting, and more watched.

The nuclear-powered campus gets the headlines, and the long-run bet may well be right. But the near-term rules are already shaping it. SB 6 requires notice to ERCOT before an existing generator registered as stand-alone as of September 1, 2025 sets up a net metering arrangement with a new large load (39.169)- the "put the data center next to the plant" deal now has to be noticed to the grid operator, not kept private.

New reactors are a later chapter. The land, water and neighbor questions are this year's.

the point

The bottleneck on Texas data centers is not only megawatts. It is site control, water, and a credible answer for the people who live next door- and the state has now written all three into the process.

Those are knowable before anyone draws a building.
