Texas has always prided itself on cheap, abundant electricity. For decades, deregulation kept prices competitive and businesses had options. But something big is happening to the grid right now, and if you run a business in Houston, it is likely to show up in your energy costs.
ERCOT, the Electric Reliability Council of Texas, which manages the power grid for most of the state, has raised its long-term demand forecasts sharply in recent years, driven in large part by data centers and other large new loads asking to connect. Just a few years ago, ERCOT was projecting modest demand increases. Now it is planning for growth on a scale Texas has not seen before.
The explosive growth of data centers and AI facilities across Texas is quietly driving one of the largest surges in electricity demand the state has ever seen. And new power supply is struggling to keep pace.
The AI and Data Center Boom Is Real, and It Is Happening Here
Over the past two years, Texas has become one of the top destinations in the country for hyperscale data centers and AI computing facilities. Large technology companies and a wave of AI startups are investing heavily in Texas infrastructure, drawn by our business-friendly environment, available land, and historically low energy costs.
The problem? A single large data center can consume as much electricity as a small city. And Texas is not adding one. It is adding dozens.
Supply Isn’t Keeping Up
Building new power generation takes time: years, not months. Between permits, construction, and grid interconnection approvals, the pipeline is long. While demand is spiking almost immediately as these facilities come online, new generation capacity is lagging behind.
This supply-demand imbalance is exactly what drives prices up. When demand outpaces supply, especially during hot Texas summers when both businesses and massive AI computing farms are drawing power simultaneously, wholesale electricity prices can spike, and over time that pressure can show up in the pricing of business energy contracts.
ERCOT has flagged increased risks of grid stress during peak periods, and energy analysts across the state watch each summer and winter closely.
What This Means for Houston Businesses
If your current energy contract is coming up for renewal in the next 6 to 18 months, you are entering a different market than the one you signed in. Pricing that looked high a few years ago may not look that way today, so start early and compare carefully.
Here’s what we’re advising our clients right now:
Review your renewal timing early. Waiting and hoping prices drop is a risky strategy in a supply-constrained market. Starting months ahead gives you time to compare offers and, if a fixed rate fits your budget, lock predictable energy costs instead of absorbing market swings.
Understand your demand profile. Demand charges, the fees based on your peak usage, can be a large share of a commercial bill, and larger accounts may also face 4CP transmission charges tied to the grid's summer peaks. Understanding when and how you use electricity can uncover ways to lower those costs.
Review your natural gas contract too. If your business buys natural gas, look at that contract alongside electricity. In Texas, power and gas prices tend to move together, so it pays to time both renewals with care.
Don’t renew on autopilot. Many businesses simply let their energy contract auto-renew with their current provider. Letting a contract roll over without comparing the market can be an expensive mistake. An independent broker can take your usage to many retail providers at once and help you compare offers on the same basis.
The Bottom Line
No one can promise where Texas energy prices go next. But the forces behind recent pressure are not going away soon: AI growth, data center expansion, and a grid that takes years to build. The real question is whether your business is positioned to handle whatever the market does.
Houston businesses that plan renewals early, understand their usage patterns, and work with an independent energy broker are in a much stronger position than those who wait and see.
