BNEF chip-based model pegs US data center demand at 207 GW by 2033

Data centers built to power AI are pulling far more electricity than forecasters expected, and the gap between estimates keeps growing. A new analysis from BloombergNEF puts likely U.S. data center electricity demand at 118 gigawatts by 2030 and 194 gigawatts by 2035, sharply higher than the firm's own outlook from last December. A separate estimate based on projected computer chip deliveries suggests demand could hit 207 gigawatts by 2033. For comparison, a gigawatt is roughly enough power for hundreds of thousands of homes.

The reason for the uncertainty is simple: data centers are being built bigger and faster than anyone predicted. A year ago, a 1-gigawatt project counted as large. Now more than 70 projects that size are in the pipeline, with some reaching up to 10 gigawatts. By the end of 2025, installed data center capacity nationwide was already 16% higher than forecasters had expected, with Texas seeing the biggest gap between prediction and reality.

This matters to homeowners because all that new electricity demand has to come from somewhere. A recent estimate from Bank of America suggests the country may need more than 230 gigawatts of new power generation over the next five years, but utilities currently plan to add only about 93 gigawatts. How that gap gets filled, and who pays for the grid upgrades needed to serve these massive facilities, could affect electricity rates and reliability in the years ahead. It's worth watching whether your own state or utility discusses data center growth when explaining future rate changes.
