Power struggle: US weighs tough rules to cut Big Tech data centers off the grid during emergencies

Big Tech’s data centers face new rules as US grids strain under AI boom.

America’s race to dominate artificial intelligence is running into an old problem: electricity.

The explosive growth of Big Tech’s data centers, the backbone of AI training and cloud services, is straining power grids to their limits, according to a report by Associated Press. Policymakers are now considering a tough-love solution: forcing these facilities off the grid during peak emergencies to keep homes and hospitals powered.

Texas was the first to move, passing a law in June that orders utilities to cut off big electric users like data centers during extreme demand periods. The memory of the deadly 2021 blackout, when dozens died during a winter storm, still looms large.

Now the idea is spreading to other regions, including PJM Interconnection, the largest US grid operator serving 65 million people across 13 mid-Atlantic states, and the Southwest Power Pool covering the Great Plains.

“Data center flexibility will be expected, required, mandated”

Since late 2022, when OpenAI’s ChatGPT triggered a global AI boom, data center projects have multiplied across nearly 20 states. Grid operators warn electricity demand will spike dramatically in coming years.

“We’re going to see that kind of thing pop up everywhere,” Michael Weber, a University of Texas energy expert told Associated Press. “Data center flexibility will be expected, required, encouraged, mandated, whatever it is.”

The warning is stark: without new rules, surging demand could swamp power grids and push electricity bills even higher. Federal data shows bills are already rising at twice the pace of inflation.

Big Tech pushes back, with diesel generators and lobbying

Tech giants say a steady power supply is non-negotiable. Companies are scrambling to install diesel backup generators and redesign operations to stay online if grids falter, the AP report added.

Industry groups like the Data Center Coalition argue that rules should remain flexible, noting not all facilities can quickly shift to backup. They also want financial incentives for voluntarily shutting down when grids are stressed.

But consumer advocates counter that ordinary households are effectively subsidising Big Tech’s enormous power appetite. “Data center load has the potential to overwhelm the grid,” said Joe Bowring, who monitors PJM’s markets.

A political and economic balancing act

The stakes go beyond electricity bills. Governors of Pennsylvania, New Jersey, Illinois and Maryland warned PJM that rigid emergency rules could scare off data center investment. These states compete fiercely to lure Big Tech’s billion-dollar projects.

Others want tougher standards. Some advocates argue data centers should adopt a 'bring your own generation' model, building their own power plants or renewable energy sources rather than leaning on public grids.

Indiana offers a glimpse of compromise. Google struck a deal with Indiana & Michigan Power for a planned $2 billion data center in Fort Wayne, pledging to reduce consumption during grid stress by delaying non-urgent tasks. Still, details remain murky, leaving consumer groups skeptical.

The bigger question: who pays for AI’s power hunger?

At the heart of the debate lies a societal trade-off. Should billions be spent on new power plants that may only be needed for a few extreme days each year?

Abe Silverman, an energy researcher at Johns Hopkins University, frames it bluntly, as cited by AP:

“Is it worth it for society to build those 10 new power plants just to serve the data centers for five hours a year? Or is there a better way to do it?”

For now, policymakers from Texas to the mid-Atlantic are betting that cutting Big Tech off during emergencies may be that 'better way,' even if it sparks a power struggle between regulators, communities, and Silicon Valley.
