Is the US power grid ready to meet the demands of data centres?

Welcome to Vitality Supply, coming to you from New York. President Donald Trump introduced a 90-day pause in additional tariffs on international locations that had been keen to barter with the US. The information despatched shares surging however oil markets have remained risky.

Though the worldwide benchmark Brent crude jumped on Wednesday to settle at $65.48 a barrel, it had fallen below $60 a barrel for the primary time in 4 years earlier than Trump introduced he would pause tariffs.

Regardless of the restoration, crude costs have fallen sharply this 12 months. My colleagues Jamie Smyth and Myles McCormick reported shale producers are dealing with their gravest threat in years as they fear concerning the results tariffs could have on the trade.

In immediately’s Vitality Supply we take a look at how the ageing US energy grid and provide chain constraints could gradual the tempo of information centre rollout within the nation, complicating Washington’s race to steer in synthetic intelligence.

Is the US energy grid prepared to satisfy the calls for of information centres?

To win the AI race the US must construct a big variety of knowledge centres throughout the nation, however consultants warn the nation’s ageing energy grids and provide chain constraints could not have the ability to assist their deployment.

Utilities are receiving an unprecedented variety of requests for brand spanking new energy capability from the trade. Sempra stated final 12 months its Texas energy utility Oncor Electrical acquired requests from knowledge centres so as to add a complete of about 119 gigawatts of potential load to hook up with the grid.

However Chris Seiple, vice-chair of vitality transition and energy and renewables at Wooden Mackenzie, stated the US energy grid’s restricted capability might curb the tempo of information centre rollout.

“The quantity of information centre capability that will get added over the course of the subsequent 5 years might be decided by how a lot vitality we will really add to the grid to assist it,” he stated.

This can be a international downside. A new report revealed by the Worldwide Vitality Company on Thursday discovered grid constraints might delay about 20 per cent of worldwide knowledge centre capability deliberate for building by 2030.

However a surge in vitality demand within the US, after 20 years of flat progress, has made the issue acute. Whereas the IEA estimates knowledge centre progress will account for a comparatively small share of future electrical energy demand, it may place important each day strain on grid operators and utilities, with AI-related knowledge amenities usually requiring way more vitality than conventional ones.

“The [data centres] which might be being talked about now are a gigawatt in capability . . . a gigawatt is concerning the dimension of town of San Francisco,” stated Jim Robb, chief govt of the North American Electrical Reliability Company, a regulatory physique that screens the reliability of the ability system within the US and Canada.

“You possibly can think about how difficult that’s going to be for us to construct not solely the ability technology but in addition the supply infrastructure to get the ability from the place you possibly can generate it to the place it’s going to be consumed,” he added.

The US energy grid can also be dealing with a rise in demand linked to the electrification of transportation and reshoring of producing. However the capability crunch linked to AI applied sciences raises particular challenges as a result of it requires considerably extra vitality assets and upgraded infrastructure to satisfy the calls for of hyperscale knowledge centres.

Whereas most knowledge centres have prioritised utilizing renewable vitality, that alone can not meet the ability demand, thereby creating the necessity for extra pure gas-fired energy crops.

Seiple stated: “You have to construct crops not solely to satisfy demand progress, to answer the modifications in capability accreditation guidelines, but in addition to interchange all of those retiring crops.”

Constructing a brand new mixed cycle energy plant, he added, is dear and has doubled in worth since earlier than the outbreak of the Covid-19 pandemic to be a median of over $2,000/ kW.

Utilising renewables equivalent to wind and photo voltaic additionally requires the necessity to replace transmission traces to move the vitality to the grid. However Nerc’s Robb stated multi-state transmission tasks can take 15 to 17 years to develop.

“We have to determine learn how to shrink 15 to 17 years to a few to 5 years,” he added.

To make issues worse, key elements of grid infrastructure together with transformers and fuel generators are dealing with provide chain constraints.

Wooden Mackenzie’s Seiple stated lead occasions for transformers, that are essential to transmission infrastructure, have tripled since 2021.

“Should you didn’t order your transformer three years in the past, you’re going to seek out it very difficult to get a transformer,” he added.

Trump’s current spate of tariffs could worsen provide chain challenges and will probably increase prices for vital infrastructure.

“Tariffs are going to make grid tasks costlier,” stated Karen Wayland, chief govt of GridWise Alliance, a coalition that advocates for modernising the US energy grid. “It’s going to exacerbate provide chain constraints.”

The uncertainties across the results of the levies may additionally complicate future funding choices for companies. Utilities have already grappled with uncertainty surrounding knowledge centre growth.

“Utilities prior to now have by no means had a lot danger related to a buyer,” Seiple stated. “They don’t know if all 10 knowledge centre tasks that need to hook up with their system will get constructed.”

Wayland stated it was troublesome for utilities and grid operators to plan as a result of they know there might be elevated energy demand however they have no idea “precisely how a lot”.

Some consultants have stated demand for knowledge centres could also be overstated. A current Vitality Intelligence report stated AI could not require as a lot vitality demand as acknowledged. They cite Nvidia for instance, which has improved its chips to be 45,000 occasions extra vitality environment friendly at some massive language mannequin duties in simply eight years.

“The overall rule of know-how is because it improves you’re bringing effectivity alongside,” stated Michael Collins, director of vitality transition analysis at Vitality Intelligence.

Earlier this 12 months, Chinese language AI start-up DeepSeek revealed it might develop a big language mannequin by utilizing far much less vitality than its US rivals. Whereas this raises the chance that the know-how could not want as a lot energy as forecast, utility corporations are nonetheless seeing a surge in demand from knowledge centres.

Dominion Vitality stated it has nearly doubled its knowledge centre buyer demand since July and Duke Vitality advised traders in February that it has not seen a pullback both, with extra electrical energy demand coming from amenities associated to generative AI. (Alexandra White)
