Artificial intelligence, once envisioned only in science fiction, is becoming commonplace in our offices and homes. Ironically, the AI-enabled features of a modern world — from internet searches to chatbots to digital assistants — are all powered by an energy system that has been going strong for over 100 years.
Just as AI may be the most significant technological advancement of this millennium, the energy grid was the most important engineering achievement of the last. It was built to last, and while the way the world produces power has evolved, how energy flows — from power sources then over poles and wires to our homes and businesses — is largely unchanged from when the system was designed.
What has dramatically changed is the demand on that system. Exelon has a number of high-potential data center projects in our pipeline that together would require 11 GW of additional load. To put that in perspective, 1 GW can power close to a million homes. As an example of the magnitude of data center development that already has taken place, in the Chicagoland area alone, Exelon helped launch 20 data centers over the past two years.
We have been modernizing and strengthening our energy grid to meet residential, small business and commercial customers’ electrification needs, and like much of the technology to which we have grown accustomed, the grid has gotten smarter and more complex. Our smart grid provides many benefits to our operations and customers, including the ability to automatically reroute power when there’s damage, improving reliability by shortening repair time and reducing customer outages.
As AI advances, it will bring even more benefits to the energy system that powers it, including predictive maintenance, bolstered cyber security and enhanced employee training. In turn, the grid will be more efficient, more reliable and better able to meet AI’s energy demands.
Exelon is proud to support the expansion of the data centers that house the computer systems, servers and storage needed to sustain AI. We see data centers as key partners, and we are committed to supporting their growth and development, while also meeting the increasing demands for sustainable and reliable electricity.
Recent proposals for co-location, a practice in which data centers are built next to a power plant, have gained attention, with FERC convening a technical conference on the subject Nov. 1 and rejecting as unsupported a precedent-setting interconnection agreement involving a data center and a nuclear generator. That agreement, which did not conform to standard terms, would have raised electricity bills for residential and other customers.
If data centers are connected to the grid — even if their first point of connection is a generator — they should contribute to the cost of the network infrastructure providing those services. Most data centers do just that. However, if co-located data centers are not recognized as network load, we estimate the annual electric bill for residential customers in the surrounding region could increase by up to $214.
Co-locating with an electricity generator also presents important considerations for the data center on how dependent they want to be on a single generator — rather than the entire electric grid — for reliable service. At the FERC technical conference, an advocate for co-location acknowledged this dependence may not be the best choice for a data center running defense critical services given the risk.
Co-location presents an opportunity to support the ongoing nationwide energy transformation and promote economic development in the communities we serve. We are proud that Site Selection magazine once again named two of our local energy companies, ComEd and PECO, to their 2024 list of the “Top 20 utilities in economic development,” based on the number of facility investment projects attracted to their service areas, the capital investment and potential for job creation.
We also agree with the Biden administration’s desire to operate data centers within U.S. shores, mitigating concerns about foreign control of these critical assets. It is important, then, to understand and be clear: This effort can and will continue, and we will help facilitate it.
We are committed to continuing our work with data centers to meet their needs, no matter where they are located. And, even with demands that far exceed what the energy pioneers may have envisioned, the energy grid of today is ready to meet the moment, just as it was a millennium ago.
Exelon looks forward to continuing to lead the energy transformation, with future generations in mind, in a way that is equitable for all our customers and communities.
