AI, Water & Texas: What Data Centers Could Mean for Lake LBJ

Artificial intelligence may live in the cloud, but the infrastructure powering it is very much on the ground. And in Texas, that infrastructure is creating a growing demand for two resources that matter enormously to the future of Central Texas: electricity and water.

For people who own Lake LBJ waterfront homes, this may seem like a story about technology, data centers and the Texas power grid. But it is also a story about growth, infrastructure and the resources that make Central Texas such a desirable place to live.

Texas Has Become an AI and Data Center Powerhouse

Texas has attracted enormous investment in data centers, including facilities designed to support the rapidly growing computing demands of artificial intelligence.

That growth has caught the attention of state officials.

In September 2026, Gov. Greg Abbott directed the Texas Commission on Environmental Quality to halt permits sought by data centers while state agencies conduct audits of their electricity and water use. The governor’s directive came after the state began increasing enforcement of water-use reporting requirements for data centers.

According to the Texas Tribune, only about 30% of the 329 data centers surveyed by the Texas Water Development Board in 2025 submitted the required water-use information. The information matters because Texas uses these surveys to help project future water demand and plan for the state’s long-term water needs.

In other words, Texas is trying to figure out just how much water and electricity this next wave of technology will actually require.

How Much Water Are We Talking About?

A January 2026 analysis from the Houston Advanced Research Center estimated that Texas data centers used approximately 25 billion gallons of water in 2025.

That number could grow substantially.

The same analysis estimated that annual water demand from Texas data centers could reach somewhere between 29 billion and 161 billion gallons per year by 2030, depending on how quickly the industry grows and which cooling technologies are used.

At the upper end of that range, data centers could account for approximately 2.7% of total annual water use in Texas.

Why do data centers need water? One reason is cooling. The computer servers running AI applications generate enormous amounts of heat, and many facilities use water as part of their cooling systems. Water can also be associated with the generation of the electricity needed to operate those facilities.

That does not mean data centers are draining the Highland Lakes. Texas has a large and complicated water system, and data centers are located in many different parts of the state. But the numbers illustrate a larger issue: Texas is entering a period when demand for water and electricity is being driven by several forms of growth at once.

And Then There’s the Electricity

Water is only half of the story.

AI requires enormous amounts of computing power, which means enormous amounts of electricity.

ERCOT, the organization responsible for managing the Texas power grid, reported in June 2026 that it was tracking more than 438,000 megawatts of large-load electricity requests, with nearly 89% coming from data centers.

In August, the Office of the Texas Governor reported that ERCOT was considering more than 474 gigawatts of requests to connect to the Texas grid.

That is a staggering number. For perspective, it represents more than five times Texas’ record peak electricity demand. Importantly, these are requests for potential future connections, not electricity that Texas is currently consuming. Not every proposed project will ultimately be built.

Still, the scale helps explain why Texas officials are taking a much closer look at how large electricity users connect to the grid.

AI Is Becoming a Global Energy Story, Too

This isn’t just a Texas issue.

A September 2026 study published in Communications Sustainability, a Nature Portfolio journal, estimated that electricity consumption from AI-focused data centers could rise from approximately 118 terawatt-hours in 2024 to between 239 and 295 terawatt-hours by 2030.

The study estimates that would represent roughly 1% of global electricity demand.

That is a remarkable amount of energy for an industry that barely existed in its current form a decade ago.

And it helps explain why communities around the world are increasingly asking the same question:

How do we accommodate rapid technological growth without putting too much pressure on the infrastructure and natural resources that communities depend on?

Why This Matters to Lake LBJ

If you own a home on Lake LBJ, why should you care about what happens at a data center outside Austin, Dallas or another Texas community?

Because Lake LBJ is part of a much larger Central Texas system.

The Highland Lakes are connected to the region’s water supply, power generation, recreation, agriculture and growing population. As Central Texas continues to attract new residents, businesses and investment, the infrastructure supporting that growth becomes increasingly important.

Water is particularly important.

Lake LBJ is a constant-level lake, but it exists within the larger Highland Lakes system managed by the Lower Colorado River Authority. Decisions about water resources throughout the region are influenced by competing demands from communities, agriculture, industry, recreation and environmental needs.

That means the most interesting question isn’t whether an AI data center somewhere in Texas is going to affect the water level at your Lake LBJ home.

It won’t be that simple.

The more important question is how Central Texas manages growth while protecting the resources that make the region desirable in the first place.

Growth Is One of Lake LBJ’s Biggest Long-Term Stories

The same factors attracting technology companies and new investment to Texas are also helping drive population growth throughout Central Texas and the Texas Hill Country.

More people means more demand for homes, restaurants, roads, electricity, water, healthcare, recreation and other infrastructure.

For Lake LBJ homeowners, that growth can have both practical and economic implications.

More investment in the surrounding region can strengthen amenities and make the area more attractive as a second-home and primary-residence destination. At the same time, rapid growth creates challenges that communities have to manage carefully.

That is one reason we believe understanding Lake LBJ real estate requires looking beyond the shoreline.

What We’re Watching

• Texas data center water consumption: How quickly will demand grow, and where will that water come from?
• Electricity demand: How will Texas expand its grid to accommodate large new industrial and technology users?
• Central Texas growth: How will continued population and business growth affect infrastructure throughout the Hill Country?
• Water planning: How will Texas balance residential, agricultural, industrial and environmental water needs?
• Lake LBJ: What do these broader changes mean for the long-term desirability and value of waterfront property?

The Bigger Picture

The AI boom may feel like a story about computers, software and technology companies.

But underneath all of that technology is something much more familiar: land, water, electricity and infrastructure.

Texas is now having to plan for a future where all four are in greater demand.

For those of us who live, work and own property around the Highland Lakes, that’s worth paying attention to.

Because when you own Lake LBJ waterfront property, you’re not just buying a view. You’re investing in a place, a community and the infrastructure that makes the entire region work.
