On New Yr’s Eve, my greatest problem is attempting to remain awake till midnight.
However from an infrastructure perspective, New Yr’s Eve is an enormous problem. Actually, it’s one of many greatest stress checks our energy grid faces all 12 months.
That’s as a result of on New Yr’s Eve, tens of millions of individuals do the identical factor unexpectedly.
They flip switches.
Across the nation, televisions and sound techniques get turned on. Lights glow in residing rooms, bars, stadiums and metropolis squares. In lots of cities, complete skylines gentle up unexpectedly.
That sort of synchronized demand isn’t typical.
And for our getting older electrical grid, it’s something however trivial.
The Midnight Surge
Electrical energy is completely different from most issues we depend on.
It nonetheless can’t be stockpiled at any significant scale, which implies it must be generated, transmitted and consumed nearly immediately.
In the US, our energy grid is designed to function at 60 cycles per second — 60 hertz — and it should keep inside very tight margins of that frequency to keep away from gear harm or outages.
This requirement forces grid operators to match provide and demand in actual time.
When demand rises, the system slows. When demand falls, it hurries up. And if the frequency drifts outdoors its slim tolerance vary, the grid’s protecting techniques can disconnect turbines or hundreds to stabilize the community.
Even small imbalances can set off automated balancing and protecting techniques. And this will generally trigger broad outages.
On an unusual evening, demand forecasts hold our grid secure. Usually, folks come house from work, cook dinner dinner and watch TV. Then demand tapers off as they go to mattress.
However New Yr’s Eve doesn’t comply with that script. As a substitute, demand builds all through the night. Then, proper at midnight, it jumps because the ball drops.

When that occurs, there’s no margin for error.
For many years, grid operators dealt with nights like New Yr’s Eve by overbuilding capability. They stored backup turbines prepared and relied on skilled human operators to make fast selections.
That strategy largely labored prior to now. Nevertheless it doesn’t work properly with a grid that has tighter tolerances and much much less room for human delay.
As a result of in the present day’s energy grid is extra complicated than it’s ever been.
Coal and nuclear vegetation that ran at a gradual output for many years are being changed by photo voltaic and wind. These renewable sources are cleaner, however they fluctuate with climate and daylight.
The electrification of autos and industries provides new, unpredictable demand. And the rising demand of information facilities is taxing the grid like by no means earlier than.
Collectively, U.S. information facilities consumed round 4.4% of the nation’s electrical energy in 2023. That share might develop to someplace between 6.7% and 12% by the top of the last decade as AI workloads and cloud computing develop.
Supply: LBNL
And these giant information facilities are large hundreds. Some hyperscale amenities draw tens to tons of of megawatts constantly. That’s roughly equal to the ability demand of a small city.
New Yr’s Eve exposes the boundaries of a grid that was designed for a slower, extra predictable world earlier than large information facilities existed.
And that’s why AI has began to step in.
Fashionable energy grids are more and more being managed by software program that may see issues forming earlier than they occur. And these AI techniques forecast demand utilizing excess of historic averages. They ingest climate information, occasion schedules, site visitors patterns and real-time sensor readings from throughout the grid.
In different phrases, these techniques know what’s approaching New Yr’s Eve. They anticipate the midnight surge and convey extra technology on-line forward of time.
Additionally they coordinate grid-scale battery storage techniques, serving to soak up and provide vitality inside seconds when wanted.
These batteries can reply in milliseconds — a lot sooner than conventional turbines — and supply vital flexibility when demand spikes unexpectedly.
AI additionally helps the grid by briefly reducing energy use from giant customers, which may easy peaks with out clients noticing.
And when a surge does hit, AI adjusts constantly.
If a neighborhood spikes sooner than anticipated, energy flows are rerouted. If a generator stumbles, backup assets are dispatched mechanically. And if renewable output dips, saved vitality fills the hole.
All of this occurs in mere seconds.
After all, persons are nonetheless there to oversee. However they aren’t flipping switches manually anymore. As a substitute, they’re overseeing techniques that react sooner than any people ever might.
Not that you simply’re supposed to note.
So long as the lights keep on and the countdown hits zero with no hitch, most individuals by no means suppose twice about what’s taking place on the ability grid.
And that’s the purpose. If AI is doing its job, all the things simply works.
Right here’s My Take
New Yr’s Eve has more and more examined my capacity to remain up late sufficient to ring within the new 12 months.
Nevertheless it has all the time examined our electrical grid in ways in which it hardly ever experiences throughout the remainder of the 12 months. So when the ball drops and the lights keep on, it’s price remembering what’s taking place behind the scenes.
AI is making the grid extra versatile, extra resilient and extra able to supporting the subsequent wave of technological progress.
If it could possibly deal with a synchronized midnight surge throughout tens of millions of properties, certainly it could possibly deal with far more than that.
Not simply on New Yr’s Eve, however on each evening of the 12 months.
