NextEra Energy, the largest electrical utility company in the United States, said in a presentation on Tuesday that it anticipates building 15 to 30 gigawatts of new generation capacity to serve U.S. data centers by 2035. The company framed the effort as a response to the swelling, immediate energy needs of modern data-center operations.
Executives noted that access to reliable, large-scale power has become the most significant barrier to Big Tech firms that are expanding artificial intelligence, which requires energy-intensive data centers to train and deploy models. Where data centers historically could be accommodated by the existing U.S. electrical grid, their current and forecasted demand profiles increasingly call for the construction of new generation facilities dedicated to meeting those loads.
NextEra quantified the potential scale of the requirement by noting that the top end of its estimate, 30 gigawatts, is equivalent to the amount of electricity needed to supply roughly 22 million homes, a figure that the company compared to the total number of residences in the largest U.S. state of California.
The company expects that a substantial portion of the new capacity for these data-center customers will come from natural gas. In its presentation NextEra said it has a pipeline of more than 20 gigawatts of gas-fired generation projects. The company is headquartered in Florida and organizes its operations into a renewables and gas-fired development division, NextEra Energy Resources, and a regulated utility, Florida Power and Light.
The presentation did not provide further operational timelines for individual projects or additional numerical detail beyond the range of 15 to 30 gigawatts and the size of the gas-fired pipeline. The firm emphasized that the initiative responds to a widening mismatch between data-center load growth and available local grid capacity.
Summary
NextEra forecasts 15-30 GW of new electricity generation for U.S. data centers by 2035, driven largely by natural gas projects and supported by a pipeline of more than 20 GW of gas-fired capacity. The move addresses growing power constraints tied to the expansion of artificial intelligence workloads.
