HARRISBURG, Pa. — The explosive growth of Big Tech’s data centers has collided with the limits of America’s electricity grids. Policymakers are now weighing a drastic step: cutting data centers off the grid during power emergencies. The move, already underway in Texas, is spreading to other states as demand for artificial intelligence drives a historic surge in energy use.
Texas Sets the Precedent
Texas lawmakers acted first, motivated by the memory of the deadly 2021 winter blackout that left millions freezing in their homes and killed dozens. In June, the state passed legislation requiring utilities to disconnect major power users, including data centers, during extreme conditions. The idea is simple but disruptive: by removing the largest loads, there may be enough electricity left to keep households and hospitals running.
The measure targets only a handful of days each year when the grid is stretched to its breaking point. Yet those days are enough to make the difference between rolling blackouts and stability.
Texas has become a hub for data centers, thanks to cheap land and energy prices. But the growth has been so fast that new power plants cannot be built quickly enough to keep up. That reality has forced policymakers to prioritize residents over corporate servers.
Mid-Atlantic and Great Plains Grids Consider Similar Rules
The concept is gaining traction beyond Texas. PJM Interconnection, the largest U.S. grid operator serving 65 million people in the mid-Atlantic, has floated a similar proposal. Data centers in Virginia, Pennsylvania, and Ohio may no longer be guaranteed access to electricity during an emergency.
The Southwest Power Pool, which covers 18 million people across the Great Plains, has also signaled it will expand programs that require big users to cut demand. “We have no choice,” its CEO explained, pointing to surging requests from developers who want to plug massive data centers into an already strained system.
The AI Boom Is Driving Electricity Demand
The late 2022 release of OpenAI’s ChatGPT sparked an arms race in artificial intelligence. Training and running large models requires vast amounts of computing power. That computing, in turn, requires electricity on a scale few anticipated.
Michael Weber, an engineering professor at the University of Texas, put it bluntly: “Data center flexibility will be expected, required, encouraged, mandated—whatever it takes.”
Projections from multiple grid operators show electricity demand spiking sharply in the next five years, with much of the increase tied to data centers. Some states face requests for new connections so large they equal the electricity use of an entire city.
Rising Bills for Regular Customers
The strain is not just technical—it is financial. Federal data shows U.S. electricity bills have been climbing at twice the rate of inflation. Consumer advocates argue that ordinary families are, in effect, subsidizing Big Tech’s enormous energy appetite.
Joe Bowring, who leads Monitoring Analytics, the independent watchdog for the mid-Atlantic grid, warned: “Data center load has the potential to overwhelm the grid, and I think it is on its way to doing that.”
Pushback From Tech Companies
Data center operators are not standing still. Many are adding diesel backup generators and seeking to run facilities more efficiently. Yet they argue they never anticipated being asked to power themselves down to support the broader grid.
The Data Center Coalition, which represents major tech firms, has lobbied for flexibility in new rules. Some facilities can switch to backup power in minutes. Others cannot. “One-size-fits-all doesn’t work,” said Dan Diorio, a policy director at the coalition.
Industry groups have also warned that denying guaranteed power could spook investors. The Digital Power Network, representing Bitcoin miners and developers, argued that uncertainty in PJM’s markets could destabilize energy prices and drive projects to other states.
States Split on Strategy
Governors of Pennsylvania, Maryland, New Jersey, and Illinois have urged PJM to balance reliability with incentives. They argue data centers should be encouraged to invest in new energy sources or voluntarily cut demand. Simply cutting them off, they said, is not a long-term fix.
Some consumer advocates favor a more radical solution: requiring data centers to “bring your own generation.” In other words, companies would need to build their own dedicated energy plants, instead of relying entirely on the grid.
A Voluntary Model in Indiana
Not all negotiations are adversarial. In Indiana, Google reached a voluntary agreement with Indiana & Michigan Power for its planned $2 billion Fort Wayne data center. The deal commits Google to reduce electricity use during periods of grid stress, in part by delaying non-urgent computing tasks.
However, the details remain confidential, frustrating watchdogs who want to know how much the deal truly benefits ratepayers. “It’s hard to tell if this is meaningful or just window dressing,” said Ben Inskeep of the Citizens Action Coalition.
The Economic Trade-Off
The stakes are high. Data centers bring investment, jobs, and tax revenue. But they also consume power at an unprecedented scale.
Johns Hopkins researcher Abe Silverman noted that building enough new power plants to meet peak demand from data centers could cost billions. “Is it worth it to build 10 new plants just so servers can run at full capacity for five hours a year?” he asked. His answer: probably not.
Cutting large users off during rare emergencies could save money for households, who pay the most when electricity prices spike. Still, the approach tests America’s long-standing assumption that once you plug in, power is guaranteed.
What Comes Next
Texas regulators are drafting the details of their new emergency rules now. PJM will decide on its proposal in the coming months. The Southwest Power Pool is also expected to announce updates this year.
In each case, the central question is the same: how to keep the lights on for millions of families while still supporting the digital infrastructure powering the modern economy.
Big Tech insists it can innovate its way out of the problem through efficiency and renewable energy purchases. Policymakers remain skeptical, pointing to the pace of growth and the limits of grid expansion.
For now, one thing is clear. The AI revolution may reshape not only industries and workplaces, but also how America uses—and shares—electricity.
Actionable Steps for Policymakers and Industry
- Set clear emergency standards. Texas’ model shows that predictable rules can help grid operators act quickly. Regulators should ensure standards are transparent and flexible enough to reflect real-world differences among facilities.
- Expand voluntary demand response. Deals like Google’s in Indiana could be a template if structured with oversight and accountability. Independent audits should verify the actual benefits to ratepayers.
- Encourage on-site generation. From solar farms to natural gas turbines, requiring or incentivizing data centers to add their own capacity would reduce pressure on shared grids.
- Protect consumers. Any new system must shield households from rising bills. States should require utilities to publish clear data on how data center demand affects rates.
- Balance growth and resilience. Data centers bring economic value, but without limits, they threaten grid stability. States should coordinate on policies to avoid a race to the bottom.
The Bottom Line
America’s electricity system is entering uncharted territory. Data centers, once seen as quiet neighbors, now stand at the center of a battle over reliability, cost, and fairness. The outcome will affect not only Big Tech but every household that flips a light switch.
The hard question is no longer whether data centers will grow. It is whether the grid can grow with them—or whether, on the coldest and hottest days, someone will be left in the dark.
