You don’t need me to tell you how artificial intelligence (AI) is impacting the power grid; you can just ask AI. Claude, an AI assistant created by Anthropic, told POWER, “AI training and inference are driving unprecedented demand for data center capacity, particularly due to large language models and other compute-intensive AI workloads.” It also said, “AI servers, especially those with multiple GPUs [graphics processing units], require significantly more power per rack than traditional servers—often 2–4x higher power density.”
So, what does that mean for power grid operators and electricity suppliers? Claude said there could be several effects, including local grid strain in AI hub regions, the need for upgraded transmission infrastructure, higher baseline power consumption, and potential grid stability issues in peak usage periods. Notably, it said AI data centers tend to cluster in specific regions with favorable power costs and regulations, creating “hotspots” of extreme power demand.
Sheldon Kimber, founder and CEO of Intersect Power, a clean energy company that develops, owns, and operates a base portfolio of 2.2 GW of operating solar PV and 2.4 GWh of storage in operation or construction, understands the challenges data centers present for the grid. As a guest on The POWER Podcast, Kimber suggested the only way to meet the massive increase in power demand coming from data centers is with scalable behind-the-meter solutions.
“These assets may still touch the grid—they may still have some reliance on the grid—but they’re going to have to bring with them an enormous amount of behind-the-meter generation and storage and other things to make sure that they are flexible enough that the grid can integrate them without creating such a strain on the grid, on rate payers, and on the utilities that service them,” Kimber said.
Yet, data center developers have not traditionally kept power top-of-mind. “The data center market to date has been more of a real estate development game,” Kimber explained. “How close to a labor pool are you? What does it look like on the fiber side? What does the land look like?” He said electric power service was certainly part of the equation, but it was more like part of a “balanced breakfast of real estate criteria,” rather than a top priority for siting a data center. 
In today’s environment, that needs to change. Kimber said Intersect Power has been talking to data center companies for at least three years, pitching them on the idea of siting data centers behind-the-meter at some of his projects. The response has been lukewarm at best. Most of the companies want to keep their data centers in already well-established hubs, such as in northern Virginia; Santa Clara, California; or the Columbia River Gorge region in Oregon, for example. Kimber’s comeback has been, “Tell us when you’re ready to site for ‘Power First.’ ”
What “Power First” means is simple. Start with power, and the availability of power, as the first criteria, and screen out all the sites that don’t have power. “To date, data center development that was not ‘Power First’ has really been focused on: ‘What does the plug look like?’ ” Kimber said. In other words: How is the developer connecting the data center to the power grid—or plugging in? The developers basically assumed that if they could get connected to the grid, the local utility would find a way to supply the electricity needed. 
However, it’s getting harder and harder for utilities to provide what developers are asking for. “The realization that the grid just isn’t going to be able to provide power in most of the places that people want it is now causing a lot of data center customers to re-evaluate the need to move from where they are. And when they’re making those moves, obviously, the first thing that’s coming to mind is: ‘Well, if I’m going to have to move anyway, I might as well move to where the binding constraint, which is power, is no longer a constraint,’ ” he said.


173. Why Data Center Developers Should Think ‘Power First’

The rapid rise of data centers has put many power industry demand forecasters on edge. Some predict the power-hungry nature of the facilities will quickly create problems for utilities and the grid. ICIS, a data analytics provider, calculates that in 2024, demand from data centers in Europe accounted for 96 TWh, or 3.1% of total power demand. 
“Now, you could say it’s not a lot—3%—it’s just a marginal size, but I’m going to spice it up a bit with two additional layers,” Matteo Mazzoni, director of Energy Analytics at ICIS, said as a guest on The POWER Podcast. “One is: that power demand is very consolidated in just a small subset of countries. So, five countries account of over 60% of that European power demand. And within those five countries, which are the usual suspects in terms of Germany, France, the UK, Ireland, and Netherlands, half of that consumption is located in the FLAP-D market, which sounds like a fancy new coffee, but in reality is just five big cities: Frankfurt, London, Amsterdam, Paris, and Dublin.”
Predicting where and how data center demand will grow in the future is challenging, however, especially when looking out more than a few years. “What we’ve tried to do with our research is to divide it into two main time frames,” Mazzoni explained. “The next three to five years, where we see our forecast being relatively accurate because we looked at the development of new data centers, where they are being built, and all the information that are currently available. And, then, what might happen past 2030, which is a little bit more uncertain given how fast technology is developing and all that is happening on the AI [artificial intelligence] front.”
Based on its research, ICIS expects European data center power demand to grow 75% by 2030, to 168 TWh. “It’s going to be a lot of the same,” Mazzoni predicted. “So, those big centers—those big cities—are still set to attract most of the additional data center consumption, but we see the emergence of also new interesting markets, like the Nordics and to a certain extent also southern Europe with Iberia [especially Spain] being an interesting market.”
Yet, there is still a fair amount of uncertainty around demand projections. Advances in liquid cooling methods will likely reduce data center power usage. That’s because liquid cooling offers more efficient heat dissipation, which translates directly into lower electricity consumption.
Additionally, there are opportunities for further improvement in power usage effectiveness (PUE), which is a widely used data center energy efficiency metric. At the global level, the average PUE has decreased from 2.5 in 2007 to a current average of 1.56, according to the ICIS report. However, new facilities consistently achieve a PUE of 1.3 and sometimes much better. Google, which has many state-of-the-art and highly efficient data centers, reported a global average PUE of 1.09 for its facilities over the last year.
Said Mazzoni, “An expert in the field told us when we were doing our research, when tech moves out of the equation and you have energy engineers stepping in, you start to see that a lot of efficiency improvements will come, and demand will inevitably fall.”
Thus, data center load growth projections should be taken with a grain of salt. “The forecast that we have beyond 2030 will need to be revised,” Mazzoni predicted. “If we look at the history of the past 20 years—all analysts and all forecasts around load growth—they all overshoot what eventually happened. The first time it happened when the internet arrived—there was obviously great expectations—and then EVs, electric vehicles, and then heat pumps. But if we look at, for example, last year—2024—European power demand was up by 1.3%, U.S. power demand was up by 1.8%, and probably weather was the main driver behind that growth.”
