As Iciness Typhoon Fern swept throughout the US in overdue January 2026, bringing ice, snow and freezing temperatures, it left greater than 1,000,000 folks with out persistent, most commonly within the Southeast.
Scrambling to satisfy upper than reasonable call for, PJM, the nonprofit corporate that operates the grid serving a lot of the mid-Atlantic U.S., requested for federal permission to generate extra persistent, despite the fact that it brought about top ranges of air air pollution from burning fairly grimy fuels.
Power Secretary Chris Wright agreed and took any other step, too. He licensed PJM and ERCOT – the corporate that manages the Texas persistent grid – in addition to Duke Power, a significant electrical energy provider within the Southeast, to inform information facilities and different massive power-consuming companies to activate their backup turbines.
The objective was once to ensure there was once sufficient persistent to be had to serve shoppers because the typhoon hit. In most cases, those amenities persistent themselves and don’t ship persistent again to the grid. However Wright defined that their “industrial diesel generators” may “generate 35 gigawatts of power, or enough electricity to power many millions of homes.”

Within the wake of Iciness Typhoon Fern, we see alternatives to persistent information facilities with much less air pollution whilst serving to communities get ready for, get thru and get well from iciness storms.

Knowledge facilities use monumental amounts of power
Sooner than Wright’s order, it was once laborious to mention whether or not information facilities would cut back the quantity of electrical energy they take from the grid right through storms or different emergencies.
This can be a urgent query, as a result of information facilities’ persistent calls for to reinforce generative synthetic intelligence are already riding up electrical energy costs in congested grids like PJM’s.
And knowledge facilities are anticipated to want most effective extra persistent. Estimates range broadly, however the Lawrence Berkeley Nationwide Lab anticipates that the percentage of electrical energy manufacturing within the U.S. utilized by information facilities may spike from 4.4% in 2023 to between 6.7% and 12% by means of 2028. PJM expects a top load expansion of 32 gigawatts by means of 2030 – sufficient persistent to provide 30 million new houses, however just about all going to new information facilities. PJM’s process is to coordinate that power – and determine how a lot the general public, or others, must pay to provide it.
The race to construct new information facilities and to find the electrical energy to persistent them has sparked monumental public backlash about how information facilities will inflate family power prices. Different considerations are that power-hungry information facilities fed by means of herbal fuel turbines can harm air high quality, devour water and accentuate local weather harm. Many information facilities are situated, or proposed, in communities already careworn by means of top ranges of air pollution.
Native ordinances, laws created by means of state software commissions and proposed federal regulations have attempted to offer protection to ratepayers from value hikes and require information facilities to pay for the transmission and technology infrastructure they want.

All the time-on connections?
Along with hanging an expanding burden at the grid, many information facilities have requested software firms for persistent connections which might be lively 99.999% of the time.
However for the reason that Nineteen Seventies, utilities have inspired “demand response” systems, by which massive persistent customers agree to scale back their call for right through top instances like Iciness Typhoon Fern. In go back, utilities be offering monetary incentives similar to invoice credit for participation.
Through the years, call for reaction systems have helped software firms and gear grid managers decrease electrical energy call for at top instances in summer season and iciness. The proliferation of good meters permits residential shoppers and smaller companies to take part in those efforts as smartly. When aggregated with rooftop sun, batteries and electrical cars, those dispensed power sources can also be dispatched as “virtual power plants.”
A unique method
The phrases of knowledge middle agreements with native governments and utilities regularly aren’t to be had to the general public. That makes it laborious to resolve whether or not information facilities may or would quickly cut back their persistent use.
In some circumstances, uninterrupted get right of entry to to persistent is essential to care for crucial information programs, similar to scientific information, financial institution accounts and airline reservation programs.
But, information middle call for has spiked with the AI growth, and builders have increasingly more been keen to imagine call for reaction. In August 2025, Google introduced new agreements with Indiana Michigan Energy and the Tennessee Valley Authority to supply “data center demand response by targeting machine learning workloads,” transferring “non-urgent compute tasks” clear of instances when the grid is strained. A number of new firms have additionally been based in particular to lend a hand AI information facilities shift workloads or even use in-house battery garage to quickly transfer information facilities’ persistent use off the grid right through persistent shortages.

Flexibility for the long run
One learn about has discovered that if information facilities would decide to the usage of persistent flexibly, an extra 100 gigawatts of capability – the quantity that might persistent round 70 million families – may well be added to the grid with out including new technology and transmission.
In any other example, researchers demonstrated how information facilities may spend money on offsite technology thru digital persistent vegetation to satisfy their technology wishes. Putting in sun panels with battery garage at companies and houses can spice up to be had electrical energy extra briefly and cost effectively than construction a brand new full-size persistent plant. Digital persistent vegetation additionally supply flexibility as grid operators can faucet into batteries, shift thermostats or close down home equipment during times of top call for. Those tasks too can get advantages the constructions the place they’re hosted.
Allotted power technology and garage, along winterizing persistent traces and the usage of renewables, are key tactics to lend a hand stay the lighting on right through and after iciness storms.
The ones efforts could make a large distinction in puts like Nashville, Tennessee, the place greater than 230,000 shoppers have been with out persistent on the top of outages right through Fern, no longer as a result of there wasn’t sufficient electrical energy for his or her houses however as a result of their persistent traces have been down.
The way forward for AI is unsure. Analysts warning that the AI business might turn out to be a speculative bubble: If call for flatlines, they are saying, electrical energy shoppers might finally end up paying for grid enhancements and new technology constructed to satisfy wishes that might no longer if truth be told exist.
Onsite diesel turbines are an emergency answer for enormous customers similar to information facilities to scale back pressure at the grid. But, this isn’t a long-term way to iciness storms. As an alternative, if information facilities, utilities, regulators and grid operators are keen to additionally imagine offsite dispensed power to satisfy electrical energy call for, then their investments may lend a hand stay power costs down, cut back air air pollution and hurt to the local weather, and lend a hand everybody keep powered up right through summer season warmth and iciness chilly.
