Will Texas AI Demand Overwhelm the Power Grid?
ERCOT warns that Texas's AI power demand may not materialize as expected. What does this mean for infrastructure developers? #Energy #AI
Texas is planning its grid around a number that may never arrive.
In its April 2026 long-term load forecast filing with the Public Utility Commission of Texas, ERCOT projected statewide power demand could surge to nearly 368 GW by 2032 — more than four times the state's current peak demand record of 85.5 GW. That's not a typo. The projection essentially assumes Texas will need to build the equivalent of four copies of its entire existing grid in roughly six years.
And the organization that produced that forecast? It's already warning people not to rely on it.
"ERCOT has concerns with using the preliminary load forecast values for the Reliability Assessment and any other transmission and resource adequacy analysis," the grid operator wrote in that same filing. ERCOT added that it may seek adjustments based on "actual historical realization rates or other objective, credible, independent information."
That's a regulatory body publicly hedging its own numbers. For anyone making capital decisions in Texas infrastructure right now, that sentence deserves a second and third read.
What’s Actually Driving the Forecast
The 368 GW projection isn't coming from population growth or industrial expansion in the traditional sense. It's being driven almost entirely by AI data center load forecasts — the aggregated queue of proposed hyperscale and colocation facilities that developers have submitted to ERCOT as interconnection requests.
Here's the problem: interconnection requests are cheap to file. They don't require a shovel in the ground, a signed power purchase agreement, or even a finalized site. Developers routinely submit multiple speculative filings to hold their place in line. A request in the ERCOT queue is an option, not a commitment — and treating it like a commitment is how grid planners end up chasing ghosts.
ERCOT clearly understands this. The organization has already begun adjusting for what it internally calls "realization risk" — the probability that announced projects actually come online at the projected scale and timeline. That adjustment is a quiet acknowledgment that the raw queue numbers are almost certainly overstated.
This isn't a uniquely Texas problem. Grid operators across PJM, MISO, and the Southeast have grappled with the same dynamic: speculative interconnection filings flood the system, load forecasts balloon, and then a significant portion of projects stall, downsize, or quietly disappear. What makes Texas different is the scale of the gap — 85.5 GW today to 368 GW by 2032 is a projection that would strain credulity even if every filed project was fully funded and permitted.
What This Means for Infrastructure Developers
For developers and investors underwriting data center energy infrastructure in Texas, ERCOT's warning creates a genuinely complicated environment.
On one hand, real demand is real. The hyperscalers — Microsoft, Google, Meta, Amazon — are spending actual capital in Texas. AI inference workloads are not theoretical. Data center construction in Austin, Dallas, and the broader Permian Basin corridor is accelerating, and the power requirements are large. Someone is going to need to build generation, transmission, and storage assets to serve this load, and the companies that move early with credible projects will capture significant upside.
On the other hand, sizing infrastructure to the top of ERCOT's forecast curve is how you end up with stranded assets. If the realization rate on queued data center projects comes in at 40% or 50% — which would not be surprising given historical patterns — then the transmission build-out and generation capacity that got permitted and financed against a 368 GW future is suddenly dramatically oversized. Financing that risk is hard. Unwinding it is harder.
The practical implication: developers who can underwrite demand with signed offtake agreements, or who are co-locating generation directly with specific anchor tenants, are in a fundamentally stronger position than those building speculatively against the forecast. Behind-the-meter and co-located power solutions — already gaining traction in Texas precisely because interconnection delays are pushing data center operators off the grid — will likely see accelerating interest.
The Regulatory Tightrope
ERCOT's self-issued caveat is unusual, and it signals something important about where Texas grid governance is heading.
Grid operators are under competing pressures. Economic development interests — the state officials and chambers of commerce who want to attract AI investment — push for aggressive load forecasting to justify transmission investment and avoid becoming a bottleneck. But reliability obligations push in the opposite direction: if you build your adequacy planning around demand that doesn't materialize, you've misspent billions and potentially created new vulnerabilities.
ERCOT is clearly trying to thread that needle. By publishing the 368 GW number while simultaneously warning that it may not be usable for reliability analysis, the organization is essentially telling two audiences two different things at the same time. The economic development community gets to cite the big number. The engineers doing actual resource adequacy modeling get permission to apply a discount.
What comes next matters enormously for anyone with capital at stake. If the Public Utility Commission of Texas pushes ERCOT to adopt more conservative, realization-adjusted forecasts for transmission planning purposes, some proposed grid expansion projects will lose their policy justification. Permitting timelines could shift. Prioritization of interconnection requests could change. Developers who built their project economics around assumptions derived from the unadjusted forecast will face uncomfortable conversations with their investors.
How Serious Stakeholders Are Adapting
The smartest infrastructure developers in Texas aren't waiting for ERCOT to resolve its internal tension. They're building for optionality.
That means prioritizing modular, scalable generation — battery storage paired with solar, gas peakers with co-located renewables — that can be brought online in phases as demand confirms rather than betting everything on a single large build. It means structuring land and interconnection positions to preserve flexibility rather than over-committing to a specific capacity size. And it means doing serious due diligence on the actual anchor tenants behind any load forecast, rather than treating the ERCOT queue as a proxy for real demand.
On the demand side, data center operators are responding to interconnection uncertainty by exploring on-site generation options with increasing seriousness — small modular reactors, large-scale fuel cell installations, and behind-the-meter solar-plus-storage configurations that reduce or eliminate dependence on ERCOT's transmission network. That shift creates opportunities for energy project developers who can structure deals directly with hyperscalers or large colocation operators, bypassing the grid queue entirely.
The Longer View
The 368 GW number will probably be wrong. The real question is how wrong, and in which direction.
If AI adoption accelerates faster than current projections — if inference demand from autonomous systems, industrial AI, and consumer applications compounds at rates that even the optimists haven't modeled — then Texas might look back at this moment and wish it had moved faster. Infrastructure takes years to build. The cost of being too slow is paid in brownouts, lost investment, and companies relocating workloads to states with more reliable power.
If the forecasts prove significantly overstated, the cost is different: capital misallocation, stranded transmission assets, and a credibility gap between what Texas promised investors and what it could actually deliver.
The infrastructure professionals who will navigate this well are the ones who treat ERCOT's forecast as a signal about the direction of demand, not a commitment to its magnitude. Position for growth, but build the kind of projects that survive a slower ramp. Texas AI power demand is real — the timeline is the variable no one can actually price with confidence right now.
That uncertainty isn't a reason to sit out. It's a reason to underwrite more carefully.
