Data centers are using more electricity, and the new demand can put upward pressure on power prices and grid costs where generation or infrastructure is constrained. But that does not prove AI caused your bill to rise: data-center growth is only one factor, effects differ by region, and the national figures do not isolate AI or track the cause of any one household’s increase.
How data-center growth can affect an electric bill
The possible connection has several steps. More data-center demand means utilities and power markets need to serve more electricity. If available generation, transmission, or grid connections cannot keep pace, the additional load can increase wholesale prices or prompt investment in grid infrastructure. Utility tariffs and regulatory decisions then determine how energy and infrastructure costs are allocated among customers.
Each step depends on local conditions. A wholesale price change does not automatically become an equal change on a household bill: retail rates also reflect utility investment, delivery costs, regulatory decisions, and the rules for assigning costs to different customer groups. The Federal Energy Regulatory Commission’s review of 2024 markets illustrates the distinction: electricity demand rose across organized regional markets even as overall wholesale electricity and natural-gas prices declined, while retail consumer prices continued to rise.
How much electricity do U.S. data centers use?
Lawrence Berkeley National Laboratory’s 2024 report, summarized by the U.S. Department of Energy, estimated that U.S. data centers used about 4.4% of total U.S. electricity in 2023. The estimate covers data centers overall, not AI alone. The report estimated data-center use rose from 58 terawatt-hours (TWh) in 2014 to 176 TWh in 2023.

The same report projected that data centers could use 325–580 TWh in 2028, or about 6.7%–12% of total U.S. electricity. Those are projections, not measured 2028 consumption. They also describe data centers as a whole: the published national estimates do not separate electricity use attributable to AI from other computing and economic activity.
Electricity demand is rising for reasons beyond data centers. The U.S. Energy Information Administration reported that total U.S. electricity demand grew about 1.7% per year from 2020 to 2025, compared with 0.1% per year from 2005 to 2019. EIA identified data centers and expanded industrial electricity use among the near-term drivers.

Why the effect can differ by region
Data-center demand is concentrated in particular places, so a national average can obscure local grid constraints. The price effect depends in part on how quickly new generation and transmission can be built, how much spare capacity exists, and whether a region can draw power from neighboring grids.
In its February 2026 outlook, EIA modeled a high-demand scenario for 2027. The figures below are differences from EIA’s February 2026 forecast, not observed prices or estimates of household bill increases.

| Market or region | Modeled 2027 wholesale-price difference under EIA’s high-demand scenario |
|---|---|
| ERCOT | $37 per megawatt-hour (MWh) above the February 2026 forecast |
| PJM | $2.60/MWh higher, or 4% |
| New England and New York ISO | $3.00/MWh higher, or 5% |
| California and the Southwest | $1.30/MWh higher, or 4% |
These scenario results are not a ranking of household bills, states, or utilities. EIA expected the fastest data-center-related load growth through 2027 in ERCOT and PJM, but modeled a much larger price response in ERCOT. EIA attributed part of the difference to ERCOT’s limited connections to the Eastern and Western grids; PJM’s interconnections and access to other generation moderated its modeled result. The outcome in any one service area still depends on local conditions and retail rate design.
Why a rising bill does not prove data centers caused it
A bill is the result of retail rates and a customer’s electricity use, not a direct readout of wholesale-market prices. Utility infrastructure investment, delivery costs, regulatory decisions, and how costs are assigned among customer classes can all affect retail rates. A household’s own consumption also matters. FERC’s 2024 market summary—wholesale prices declining overall while retail consumer prices rose—shows why a national bill trend cannot be inferred from wholesale prices alone.

Data-center demand can contribute to pressure on power systems, but national demand figures and modeled market scenarios cannot identify why an individual customer’s bill changed. To understand a particular increase, compare the bill’s usage and rate details over time and consult the local utility or regulator for applicable rate changes; the national statistics do not substitute for that local explanation.

- Assign system costs fairly. Rates and contracts can account for the infrastructure needed to serve a large customer rather than shifting those costs unfairly to other customers.
- Limit stranded-investment risk. If a utility builds for expected demand that does not materialize, regulators can consider how to protect other ratepayers from paying for unused investment.
- Plan for resource adequacy. New demand can outpace supply, so planning must address whether enough reliable resources will be available.
- Share risk for emerging technologies. Rate design can address uncertainty around rapidly changing large-load customers and their future electricity needs.
- Consider carbon-free supply and onsite generation. Options such as carbon-free matching or onsite generation may provide capacity, subject to the relevant system and regulatory arrangements.
In February 2025, FERC opened a proceeding focused on co-location of large loads, including AI-enabled data centers, with generation in PJM. The Commission said PJM’s tariff did not appear to sufficiently address rates, terms, and service conditions for co-location arrangements, raising questions about reliability and fair consumer costs. That was the opening of a proceeding, not a final rule or a resolved case.
Can digital services offset their electricity use?
Digital activity can sometimes use less electricity than a physical alternative for the same delivered task, but that comparison does not erase the increase in data-center demand. The UK Department for Energy Security and Net Zero summarized commissioned research comparing full delivery chains for video streaming versus Blu-ray, eBooks versus printed books, and AI-powered translation versus human translation. Under the study’s scenarios, the digital option matched or used less electricity than the physical alternative.
A 2026 follow-up expanded the comparison to ten additional use cases and found results varied by service; in the cases examined, AI-assisted work that increased productivity typically reduced electricity use per task. The comparisons hold the delivered activity constant and abstract away from activity growth caused by digitalization. They therefore do not establish that data-center expansion reduces total electricity demand, nor do they show a U.S. retail-rate effect.
