Why power, not labor, is the constraint on nearshoring and AI data centers in Mexico

In Mexico the binding constraint on a new data center or factory is a connected megawatt, not a worker, and as of 2026 some projects in Querétaro have waited two years for one. That is the whole thesis of the energy infrastructure company I am advising, which rents generation to data centers and manufacturers there, and it is why I now spend as much time on substations as on store shelves. Here is what the numbers say, with the sources.

Where the data centers are, and how much power they have

As of 2026, Querétaro holds 72 percent of Mexico’s 279 megawatts of operating data center capacity, with another 181 megawatts under construction, and the sector expects the state to exceed 1,300 megawatts installed by 2031, according to the Mexican Data Center Association (MEXDC) figures reported by Clúster Industrial. AWS announced a $5 billion infrastructure region for Querétaro in 2024, operating since 2025, per DatacenterDynamics.

The largest announced project shows the scale of the gap. CloudHQ’s Querétaro campus is reported at $4.8 billion for six hyperscale buildings and 900 megawatts of critical IT load, per Por Esto in September 2025, while BNamericas describes six buildings of 48 megawatts each, 288 megawatts of IT load, at about 70 billion pesos. The two figures likely describe different phases; either way, one campus wants more power than the entire country’s data center fleet uses today.

The grid is the bottleneck, and the utility’s response is small

The state utility’s public answer has been incremental. In January 2026, CFE planned to install 26.8 megawatts of available capacity in Querétaro, mainly for data centers and industrial projects, as reported by DPL News. That is about a tenth of today’s operating fleet and a fraction of one hyperscale campus. Xataka México reported in 2026 that some data center projects in Querétaro have waited two years for a connection to the grid, and that each new project needs a connection able to carry its full demand around the clock.

Generation is not the problem everywhere. As of 2024, grid operator CENACE said northeast Mexico had enough excess generation to cover an increase in industrial activity, and the bottleneck was transmission to the new industrial parks, according to Argus Media. Companies setting up plants had to invest in power lines themselves to bring electricity in. That is the pattern across the country: electrons exist, wires to the site do not, and the wait for them is measured in years.

What the hyperscalers do instead of waiting

They build their own path to the grid. CloudHQ’s campus will connect at the 400 kilovolt level through a private, double-circuit transmission line, with initial power secured for 200 megawatts, a private on-campus substation sized for up to 900 megawatts, and grid milestones targeted toward the second quarter of 2027, per Por Esto and BNamericas. A hyperscaler can carry that: the capital, the two-year wait, the engineers. A mid-size manufacturer or a 20 megawatt colocation operator cannot, and that is most of the nearshoring demand.

Why rented power is the bridge

If the wire to the site takes two years and the project has a customer today, the gap is a rented megawatt. Generation on the customer’s land, owned and operated by someone else, metered and billed, running until the grid connection lands and then moving to the next site. The economics are the same as the equipment-rental businesses I have seen in distribution: the customer pays for availability, the operator owns the asset through many customers, and the asset moves to where the constraint is.

What I am watching, as the advisor to a company doing exactly this, is three numbers:

• The connection wait at the site, in months. Two years, per the Querétaro reports, is the number that makes a rental contract rational. If CFE’s transmission plan shortens it, the rental term shortens with it.
• The customer’s cost of a delayed start. A data center with a signed tenant loses more per month of delay than the rental costs. A factory with a nearshoring contract is the same.
• The fuel and the emissions line. Rented generation is gas or, increasingly, gas plus storage. The tenant’s sustainability commitments decide what can be rented, and Argus flagged clean energy specifically as the shortfall for nearshoring in 2024.

What a rented megawatt has to beat

The arithmetic a tenant runs is simple, and it is the same one I ran as a distributor when a supplier’s truck was late. Take the revenue the site earns per month once it is live, multiply by the months the grid connection is away, and compare that to the rental cost of the same megawatts over the same months. For a data center, a signed hyperscale tenant pays by the megawatt of IT load per month; two years of that against a leased generator and its fuel is not a close call. For a factory, the number is the nearshoring contract’s monthly volume and the penalty for missing the start date. In both cases the rented power is a bridge loan paid in kilowatt hours, and the lender is whoever owns the fleet.

Three things make the bridge shorter or longer. Plan México’s fifteen designated industrial hubs, with simplified procedures for investments through September 2030, concentrate new demand in the same corridors that are already waiting, which lengthens the queue where it is longest. CFE’s transmission plan, including the five 230 kilovolt substations and the line of more than 80 kilometers toward Querétaro reported by DatacenterDynamics, shortens it once built, and “once built” is the variable nobody can price yet. And the tenant’s own willingness to build a private line, as CloudHQ is doing, decides whether it needs the bridge at all. Most tenants are not CloudHQ.

I will name the company and its terms here when they are announced. Until then, this is the thesis, and the letter is where the data lands as it comes in. More on the energy for manufacturing and AI data centers in Mexico hub.

Frequently Asked Questions

How much data center capacity does Mexico have?

As of 2026, Mexico has 279 megawatts of operating data center capacity, with 72 percent of it in Querétaro and another 181 megawatts under construction, according to the Mexican Data Center Association as reported by Clúster Industrial.

Why is power the constraint on data centers in Mexico?

As of 2026 some Querétaro data center projects have waited two years for a grid connection, per Xataka México, and CFE’s January 2026 plan added only 26.8 megawatts of capacity in the state, a fraction of a single hyperscale campus.

Does Mexico have enough electricity generation for nearshoring?

In parts of the country, yes. As of 2024, CENACE said northeast Mexico had excess generation for new industrial activity, according to Argus Media; the shortfall is transmission to the new industrial parks, which companies have had to build themselves.

What is the largest data center project in Mexico?

CloudHQ’s Querétaro campus, reported in September 2025 at $4.8 billion and 900 megawatts of critical IT load by Por Esto, with a private 400 kilovolt transmission line and grid milestones targeted for the second quarter of 2027.
