A huge winter storm that has arrived 34 states left hundreds of thousands of people without electricity. Bitterly chilly temperatures remain after the fern winter storm they continue to test power gridsAlready under stress against the flood of novel AI data centers.
Wholesale electricity prices skyrocketed in Virginia over the weekend the state with the most data centers. And while that’s not surprising at a time of skyrocketing demand for heating energy, it could add to growing dissatisfaction over rising utility bills that has fueled opposition to data centers across the United States. Utilities and network operators were already struggling to meet the demands growing demand for the power of artificial intelligencewhich could make preparing for a weather disaster even more challenging.
“It certainly creates more price volatility,” says Nikhil Kumar, program director at energy consultancy GridLab.
“It certainly creates more price volatility.”
Kumar is quick to add that it is still too early to determine exactly what impact data centers have had on power grids during this week’s freeze and that the effects may vary from place to place. But this week’s stress test is worth watching given the challenges facing power grids as the United States grapples with a changing energy landscape and a changing climate.
In Virginia, wholesale electricity prices rose above $1,800 on Sunday, up from about $200 the day before, As reported by CNBC. The largest energy supplier Utility Dominion Energy did not immediately respond to questions Edge about the factors influencing rising wholesale costs and how much this will impact individual customers’ bills. Business announced on Monday that it restored power to 85 percent of the 48,000 customers affected by the storm in Virginia.
Remember, many various problems increase energy costs. The demand for electricity is grows more steeply more than in over a decade thanks to AI data centers, as well as domestic manufacturing and electrification of homes and buildings. Utilities also have to spend a lot of money to upgrade venerable infrastructure, as well as repair damage from growing climate disasters such as storms that have contributed to longer power outages in the US.
With power grids now nearly a century venerable and a growing need to expand transmission lines to connect novel energy sources and customers, “we’re working with our grandfather’s Buick,” says George Gross, professor emeritus of electrical and computer engineering at the University of Illinois’ Grainger College of Engineering.
When one local utility is faced with an emergency, it can usually pull additional resources from others. Officials were more concerned that the winter storm would limit that kind of aid, given how vast an area it affected. “So many of them get into the exact same problems that you can’t always get help from your neighbors,” Gross says.
Extreme weather causes prices to rise due to a surge in demand for heating or cooling and congestion on power lines. Supply shortages could also make power more costly and escalate the risk of outages if periods of freezing weather halt production of natural gas, the primary source of electricity and heating in the U.S. Ice accumulating on power lines and tree branches – the biggest threat to power grids this week – could lead to power outages.
We saw all of these factors come into play during Winter Storm Fern. They also led to more devastating power outages in Texas in 2021, with millions of residents losing at least power Winter storm Uri killed 246 people.
Fortunately, this week’s freeze wasn’t as devastating, thanks in part to the preparations of utilities and power grid operators. Especially Texas more batteries installed in the field of energy storage from 2021, co it helped this week.
Over the past few days, the Department of Energy has also issued orders to supervisory grid operators Texas and many of East Coast allowing them to deploy backup generators in data centers and other vast industrial facilities “regardless of restrictions established in environmental permits or state law.”
And yet we don’t know how much these measures can support limit the supply crunch because it’s unclear how it will work logistically and what authority the federal government has in such cases, experts say Edge. According to Joshua Rhodes, a researcher at the University of Texas at Austin, the order has not yet applied to generators in Texas because the state has not reached a high enough energy alert level.
“If this is going to be a tool that we’re going to use, we need to think about it well in advance before we start looking at a winter storm,” he says. “Policy-making in emergencies does not usually lead to the best policy.”
High energy prices may ultimately encourage AI data center operators to voluntarily reduce electricity consumption during periods of demand spikes. They can even make money this way through so-called demand response programs. Likewise energy-intensive data centers used as cryptocurrency mines have made millions in recent years he has been doing just that. But Rhodes doesn’t expect AI-obsessed tech companies to follow suit anytime soon.
“There’s a lot of hype right now,” Rhodes says. “They barely care about the price of electricity, it’s de minimis in terms of their AI value generation.”
Above 489,000 customers As of this writing, power is still out across the United States on Tuesday. Until the frost subsides, the risk of ice accumulation on critical infrastructure will not decrease either.
