The Data Center Surge: The Latest Energy Dilemma and the Path Forward

Originally published on Energy Connects

The explosion of data-driven technologies, particularly artificial intelligence (AI), has catapulted data centers to the forefront of discussions in the energy sector. Once quietly running in the background of global digitalization, these facilities now stand as one of the most significant drivers of energy demand and grid transformation.  

The Growing Appetite of Data Centers

Data centers are already energy-intensive, consuming 1 – 1.5% of global electricity and generating 1% of energy related greenhouse gas emissions. Now, AI has taken the world by storm and data center power demand is growing even more rapidly. This is in part because AI data centers use 5 – 10 times more power than traditional data centers. The International Energy Agency (IEA) forecasts data center electricity consumption will surpass 1,000 TWh in 2026, effectively doubling the levels from 2022. To contextualize the magnitude of this power demand, 1 TWh can power 70,000 homes a year. This means that data centers could consume the equivalent of 70 million homes’ energy needs in 2026. 

Fueled by the scaling of new technologies like AI, the US is anticipated to be the fastest growing market for data centers, with demand surging from 25 GW in 2024 to over 80 GW in 2030. According to the Electric Power Research Institute (EPRI), data centers may consume up to 9% of US electricity in 2030 – a quantity capable of seriously impacting grid reliability.

The Cascading Effects of Data Centers' Insatiable Thirst for Energy

The above estimations highlight the sheer scale and pace of data center expansion, and load changes of this magnitude have considerable implications for the energy industry and data centers alike. Here are some of the potential impacts.  

Strain on Grid Infrastructure, Reliability and Energy Transition

The existing grid infrastructure is aging, and it is already struggling to keep up with loads from growing industry and electrification, all while facilitating a global energy transition. Data centers are and will continue to further impact the grid with more load that needs to be interconnected to the grid, and served - ideally with clean energy, nonetheless. Additionally, interconnection queues have been notoriously long and slow for new generation projects for some time. The need for data centers, and the generation to support them, to be added to the interconnection queue compounds the problem. For data center developers and owners, this could make it harder to get their projects across the line – especially since timelines for grid investment and buildout are longer than development cycles for data centers.     

Some experts have warned that AI and data center load growth could threaten grid reliability and slow the energy transition. Already, the retirement of some coal plants in the US has been delayed to meet growing power demands driven by data centers. These are major concerns for utilities, grid operators, and data centers alike as grid operators and utilities are charged with supplying power reliably, and data centers require a constant and reliable flow of energy for operations. Additionally, the above groups often have ambitious clean energy targets that must be met, meaning a slowed energy transition is bad news for everyone involved.  

Economic Shifts

The significant energy demands of data centers, alongside their requirement for carbon neutral energy, have turned companies like Microsoft, Google, and OpenAI to nuclear energy. These organizations are investing in nuclear restarts and next generation small modular reactors to meet their burgeoning energy needs. The costs are significant – to get a unit of the Three Mile Island nuclear plant back online by 2028, Constellation Energy plans to spend approximately $1.6 billion. This is funded by a 20-year power purchase agreement (PPA) with Microsoft. 

What’s interesting is that while nuclear energy can be controversial from a safety standpoint, one of the main drivers of nuclear plant shutdowns has been economics, rather than technical or safety issues. Data Center Frontier notes that given the magnitude, “the power demands of AI may well restructure the energy generation model worldwide.”  

Nuclear or not, the costs associated with building out the generation and transmission required to support rising data center consumption are significant. According to a report by Bain & Company, it could require over $2 trillion in new generation resources alone. A challenge for utilities and data centers alike is to ensure that these costs are not passed on to ratepayers, and to determine how to allocate these costs.
