Texas's Data Center Boom, By the Numbers: What ERCOT's Capacity Projections Mean for Mechanical Contractors

A tech story that's actually an industrial story

The numbers coming out of Texas keep getting bigger. Roughly $89.5 billion in data center construction is active in the state right now, with Taylor County leading, according to Industrial Info Resources' August 2026 tracking. ERCOT's summer peak demand forecast reached 92.2 gigawatts — a new high-water mark above the 85.5 GW record set in 2023. Data centers alone account for about 73% of the projects sitting in ERCOT's interconnection queue.

Headlines call this an AI story. On the ground, it's one of the largest industrial construction programs in the country — concrete, steel, water, and power, delivered on tight schedules through Texas summers.

Abilene is where the numbers get real

The Stargate campus outside Abilene is the clearest example inside that $89.5 billion figure. As of mid-2026, the flagship site spans roughly 1,100 acres and about 4 million square feet. Crusoe reported topping out the final building on a campus targeting around 1.2 gigawatts of capacity — a milestone the company credited to more than 7,000 construction workers on site. City officials expect construction on the broader Stargate One campus to continue through early 2027.

That kind of buildout doesn't run on schedule by itself. Every building added to a campus like this needs its own flushing, filtration, and commissioning sequence before it can go live — and that work runs in parallel with the concrete and steel, not after it.

The bottleneck isn't the buildings anymore — it's the grid

The more interesting shift in 2026 isn't construction pace. It's that the grid conversation has finally caught up to it. ERCOT created a new "Batch Zero" review process in June 2026 specifically to work through a backlog of pending data center interconnection requests as a group rather than one at a time. Governor Abbott separately directed state regulators in June 2026 to make sure new data centers don't raise residential electricity costs or strain local water supplies — and a moratorium on new data center approvals followed in August 2026, pending an audit process. That moratorium doesn't touch the $89.5 billion already under construction.

What this means for mechanical readiness work

None of this changes the work already underway. It changes what that work increasingly looks like. As more campuses bring on-site generation — gas turbines, microgrids, battery buffering — to manage grid uncertainty, the systems tied to that infrastructure become as central to a project's readiness sequence as the core cooling loop itself: freeze protection circulation, glycol injection, heat-load commissioning support. A grid operating closer to its margin also raises the cost of a commissioning delay. There's less room to push a system online a few weeks late when the interconnection process behind it took months to secure.

For mechanical contractors and GCs working Texas hyperscale builds, the practical read is simple: this scope is getting broader, not narrower, as these projects scale.

Frequently asked questions

How much data center construction is currently happening in Texas?

Roughly $89.5 billion in data center construction is currently active in Texas, according to Industrial Info Resources' August 2026 tracking, with Taylor County (Abilene) leading the state.

Why does ERCOT's grid capacity matter for data center construction schedules?

Data centers make up the majority of new large-load demand on the ERCOT grid, and the interconnection process for that power has become a scheduling factor in its own right — ERCOT introduced a new batch review process in mid-2026 specifically to manage the backlog of data center connection requests.

Is Texas still approving new data centers?

As of August 2026, a moratorium on new data center approvals is in effect while a state audit process takes shape, though this does not affect projects already under construction, including the roughly $89.5 billion currently active in the state.

What is the Stargate project in Abilene?
Stargate is a large AI data center campus outside Abilene backed by OpenAI, Oracle, SoftBank, and MGX, spanning roughly 1,100 acres and targeting around 1.2 gigawatts of capacity, with construction expected to continue through early 2027.
