The next contest for computing power may be decided by who can connect a data center to the grid before its processors grow old. An AI company can order chips, sign a lease, and announce a campus. None of those acts delivers a dependable megawatt to a particular parcel of land. That requires generation, transmission capacity, transformers, substations, cooling equipment, and a contract that settles who pays when the grid must be rebuilt. The physical work is stubbornly indifferent to the speed of a software release. My estimate is that electricity will increasingly determine where American AI capacity is built and who can afford to build it. It does not follow that the United States is running out of power. The problem is matching large, concentrated, nearly continuous loads to power that is available at the right location and on the right schedule. That distinction will decide whether today’s data center announcements become operating machines. A national forecast meets a local socket The scale is real, even if the precise destination is uncertain. Lawrence Berkeley National Laboratory’s 2024 data center study estimated that U.S. facilities consumed 58 terawatt-hours of electricity in 2014 and 176 terawatt-hours in 2023. Its 2025 update, published in June 2026, places 2030 demand at 649 terawatt-hours in its reference case, with a broad compounded uncertainty range of 521 to 843 terawatt-hours. That reference case would account for 11.8 percent of U.S. electricity use, according to the laboratory. These are estimates and forecasts for all data centers, not a meter reading for AI alone. The multiplication deserves attention. Relative to the 2023 estimate, the 2030 reference case is about 3.7 times as large. A terawatt-hour is a billion kilowatt-hours; an annual total gives a sense of the fuel and generation required. It does not say whether a proposed campus can be served on a hot afternoon in northern Virginia, or whether a transmission line can deliver power to an Ohio substation without an upgrade. Electricity is delivered through a network with addresses, limits, and neighbors. Berkeley Lab builds its forecast from expected equipment shipments, the power each device draws, cooling performance, and the types and locations of facilities. Its range reflects consequential uncertainty. The report’s sensitivity cases include different assumptions about graphics-chip shipments, chip lifetimes, and the amount of electricity AI servers draw while idle or in use. A forecast this wide should discipline anyone announcing an inevitable national shortage. It should also discipline anyone treating the lower bound as comfortable spare capacity. For a developer, the first question is not whether the nation produces enough electricity over a year. It is whether a utility can deliver the requested load to the site at the promised date, including during a regional peak or an equipment failure. A large campus can need new transformers and high-voltage work. New generation may have to enter the system. The developer’s timetable, the utility’s construction schedule, and the grid operator’s reliability test have to meet on the same calendar. They frequently do not. Even the word power hides several separate jobs. Generation makes electricity. Transmission carries large quantities over long distances. Substations change voltage and direct the flow. Distribution and site equipment deliver it to the building. Backup systems and cooling keep a brief fault from becoming a failed service. A new gas plant can address one problem and leave a transmission constraint untouched. A transmission line can reach a region while the last substation serving a chosen parcel remains full. A data center is therefore built twice: once as a computing facility, and again as a claim on the electrical system around it. The queue contains a political decision PJM, the grid operator serving much of the Mid-Atlantic and Midwest, offers a useful test. Its January 2026 long-term forecast projects a summer peak of 160,451 megawatts in 2027 and 191,017 megawatts in 2031. Those figures cover the entire PJM system, including homes, businesses, and industry. They must not be described as data center demand. PJM does identify data centers among the major sources of expected growth, while acknowledging uncertainty about which proposed projects will materialize. PJM has already revised its near-term outlook downward from the prior year’s forecast after changing its treatment of electric vehicles, economic growth, and large-load requests. Its new process demands firmer commitments for nearby years and discounts less certain projects farther out. That is a healthy correction. A company can ask several utilities about several sites while intending to build only one. If each inquiry becomes an assumed future load, the grid may plan around a ghost population of server halls. If planners discount serious projects too aggressively, they can fail to build capacity that customers really need. Either error costs money. This is where an engineering problem becomes an argument about authority. Who gets a firm reservation on scarce capacity? What proof of construction should be required? When a new customer triggers a substation or transmission upgrade, how much should that customer pay, and how much should be charged to existing households and businesses? Those choices determine who enters the computing market. A large firm can hold land, fund studies, sign long contracts, and consider building its own power supply. A smaller competitor has a shorter financial runway. Federal regulators have begun to confront the issue directly. In December 2025, the Federal Energy Regulatory Commission directed PJM to clarify its rules for data centers and other large customers located alongside power plants. In June 2026, FERC told six regional grid operators to justify or revise rules governing how large users connect. Its stated concerns include the speed of studies, the allocation of transmission costs, power plants built near large customers, and service for customers able to reduce their grid draw. The question of a data center beside a power plant sounds simple until the grid needs that plant on a difficult day. Does the new facility take output that would otherwise reach other customers? Does it buy backup service from the network? What happens when its private generator trips? A campus can be physically close to generation yet remain electrically and financially connected to everyone else. FERC’s intervention is evidence that the bottleneck includes rules about reliability and payment, not merely the ability to pour concrete. The strongest objection is also a plan There is a serious case against treating electricity as a lasting brake on American AI. High prices attract investment in generation and grid equipment. Developers can choose sites with available capacity, contract for power, phase a campus’s opening, or build generation nearby. Better chips and software may deliver more computation for each unit of electricity. Some computing tasks can move in time or place. America’s capital markets and large technology firms can finance projects that few rivals could attempt. I take that objection seriously. In fact, it helps explain why the American advantage is substantial. The United States has companies prepared to buy extraordinary amounts of equipment and pay for the physical plant around it. But the objection describes a construction program, not an automatic market adjustment. A more capable chip can lower the energy required for a given task while making still larger and more profitable tasks possible. Power saved per operation does not guarantee lower total consumption. A generator built near a campus also needs fuel, cooling, permits, maintenance, and a clear agreement about grid support. Nor should every kilowatt-hour be treated as interchangeable. Annual production from a new plant can look ample on paper while its output arrives at the wrong hour or on the wrong side of a constrained line. A data center may tolerate interruptions for some work, such as a training run that can pause and resume. Other work, including services used by customers continuously, calls for steadier supply. The mix matters. So does the ability to move workloads among sites when one region is under strain. These are design choices with costs, and they should be compared with the expense of building firm electrical capacity. The strategic implication is narrower, and stronger, than a slogan about an AI power crisis. Access to processors remains important. Yet a nation can own impressive chips and fail to put them to work if power delivery falls behind. Within the United States, regions that can connect substantial new loads without shifting undue costs onto existing users should attract operating facilities sooner. Firms able to secure sites, equipment, and credible power contracts will gain time. Time matters when expensive processors lose commercial value while sitting idle. The national government has a role, though no federal order can make a local transformer appear overnight. It can demand honest forecasts, support transmission construction where warranted, and insist that connection rules state plainly who pays for what. States and localities control many of the siting decisions. Utilities must procure and install equipment. Private developers have to reveal enough about their projects for the public system to distinguish an actual campus from a speculative reservation. American AI capacity will be assembled by all of them, one electrical connection at a time. The evidence that would weaken my judgment is straightforward: major data center regions repeatedly connecting new facilities on schedule, without significant grid upgrades, rising reliability concerns, or costs shifted to other customers. Evidence that would strengthen it includes delayed openings attributed to power
