For years, many American utilities planned around slow or almost flat growth in electricity demand. The AI boom has changed that story. In January 2026, the U.S. Energy Information Administration said electricity use is now expected to rise for four straight years for the first time since 2007, making this the strongest four-year growth period since 2000; it identified large computing centers as the main driver. The International Energy Agency adds an even bigger perspective: data centers used about 415 terawatt-hours worldwide in 2024, the United States accounted for the largest share, and U.S. data centers are expected to make up nearly half of the country’s electricity-demand growth to 2030.

That demand surge is now reshaping the rules of the power market itself. On June 18, 2026, FERC ordered all six major U.S. regional grid operators under its jurisdiction to justify or reform the tariffs that govern how data centers and other large users connect to the grid. The agency highlighted five areas for change: faster application and study processes, stronger protections against cost shifting to ordinary customers, clearer rules for co-location and behind-the-meter generation, new transmission services for flexible large loads, and better study methods for generators serving nearby data centers. In effect, this is not just a story about “more electricity.” It is a story about a market being redesigned so that huge new customers can get power faster without pushing unfair risks onto everyone else.

The scramble for supply is also changing what kind of power gets built and how it is used. DOE says total U.S. electricity demand could grow by roughly 15% to 20% in the next decade, and that data centers could consume up to 9% of U.S. electricity generation annually by 2030. At the same time, AI training centers are not ordinary factories: DOE notes that they can create rapid load fluctuations, or “oscillations,” because thousands of chips work in synchronized cycles. That is why the winners in this new market may not be only big generators, but also storage operators, transmission developers, flexible-load providers, and firms that can combine speed, reliability, and price discipline. Renewables and natural gas are expected to lead near-term supply growth, while nuclear and geothermal are gaining attention as reliable long-run partners for AI infrastructure.
