Study reveals lower-income and rural households bear majority of U.S. data center grid upgrade costs

A study published on November 9 in Nature Energy by researchers at Cornell University has revealed that ordinary households, particularly lower-income and rural residents, are shouldering the financial burden of massive energy infrastructure upgrades driven by the artificial intelligence boom. Investigators analyzed growth across four major U.S. power grids from 2020 to 2025 and found that data centers have significantly spiked wholesale energy prices while paying only a fraction of their associated grid expansion costs.

According to the findings, data centers covered just 38% of their infrastructure expenses in 2025, amounting to $3.12 billion out of an $8.25 billion bill. The remaining 62%, totaling $5.13 billion, fell largely onto local residents. For the lowest-income households, these extra energy expenses reached up to 28% of their total incomes. Overall transmission investments in energy projects surged from $2 billion in 2020 to $34 billion in 2025, heavily fueled by the rapid construction of facilities designed to power heavy artificial intelligence workloads.

Led by Fengqi You, a professor in energy systems engineering, the research team examined records from 4,000 existing and proposed data centers, utility rate filings, and federal data across major hubs including northern Virginia, the Dallas-Fort Worth area, the Midwest, and the southern San Francisco Bay area. The data showed that data center expansion hiked wholesale electricity prices by nearly 10% or more by 2025 in the hardest-hit regions, with jumps reaching 15% in Virginia and 20% in the southern Bay Area. Conversely, regions with limited construction like New York and New England avoided clear price surges.

While highlighting the economic trade-offs—such as each gigawatt of capacity creating an average of 2,700 direct jobs and 15,000 total jobs—the authors emphasized that current cost-allocation rules fail to match who actually drives new grid demand. What to watch next: Ongoing policy debates across state governments and Congress regarding how utilities bill infrastructure expansion as data center electricity consumption is projected to reach up to 17% of the U.S. total by 2030.
