But an increase is not automatic: the outcome depends on local power supply, utility investment decisions, and whether the data center or other customers are assigned the costs.
How a data center’s power demand can reach a household bill
A data center may require utilities and grid operators to add or upgrade generation, transmission lines, substations, or local distribution equipment. If those costs are necessary to serve a new large customer, regulators must decide how much the customer pays directly and how much—if any—is recovered from other customers through rates.
There are two main paths to a household bill. First, a utility may recover some infrastructure or operating costs through the rates it charges customers. Second, when new demand competes for limited electricity or capacity in a constrained area, wholesale power costs may rise and eventually affect retail rates. The size and timing of any retail effect depend on local circumstances and regulation.
The reverse can also happen: if a data center adds sales over which a utility can spread some existing fixed costs, average rates may fall. That possibility helps explain why recent national studies reach different conclusions; neither outcome can be assumed for every utility territory.

How large is the data-center electricity load?
Data centers are a growing U.S. electricity load, but estimates of their future share are projections, not measured outcomes. Lawrence Berkeley National Laboratory’s 2026 estimate gives a 2030 reference case and a range of modeled scenarios:
| Measure | Estimate | How to read it |
|---|---|---|
| Share of total U.S. electricity in 2023 | 4.4% | Reported in a 2024 Department of Energy summary of LBNL’s 2024 report; this is historical consumption. |
| Share of total U.S. electricity in 2030 | 11.8% reference case; 9.5%–15.3% scenario range | LBNL’s 2026 model estimates, not measured consumption. |
| U.S. data-center electricity use in 2030 | 649 TWh reference case; 521–843 TWh uncertainty bounds | LBNL’s 2026 model estimates. The bounds reflect uncertainty and are not a forecast of what any one utility will serve. |
A separate DOE summary of LBNL’s 2024 report projected that data centers could use 6.7%–12% of U.S. electricity by 2028. That earlier projection is useful historical context, but the later LBNL estimate is the more recent source here for a 2030 outlook. Even a large national share does not show that every region is short of power or establish what a particular household will pay.

What national price studies have found
Two studies published in 2026 reach opposing conclusions about historical average U.S. retail rates. They examine different data and methods, and their estimates should not be averaged into a single result.
| Study | Period and finding | Important qualification |
|---|---|---|
| Robyn Meeks, Jacquelyn Pless, Zhiyuan Qi, and Zhenxuan Wang, MIT CEEPR working paper | For 2010–2024, reports average retail prices rising 2.7% after data-center entry, including a 2.1% increase for residential customers. It reports a 5.6% average retail-price rise among investor-owned utilities. | The authors report smaller effects at publicly owned utilities and no detected effects among cooperatives; effects were also larger in states with deregulated generation. These are study estimates, not a guaranteed change for a particular household or utility. |
| Asa Watten, John Bistline, and Geoffrey Blanford, arXiv preprint | For 2015–2024, its instrumental-variables analysis estimates modest average U.S. retail-rate reductions attributed to data centers. | The abstract reviewed does not state a percentage. The authors warn that future supply constraints could reverse the historical effect. This is a preprint, not a universal prediction. |
The MIT paper is a working paper, and the opposing study is an arXiv preprint. Their disagreement is a reason to look at local utility conditions, not evidence that one result applies everywhere. Neither supplies a universal dollar amount for an individual household. A bill also reflects the household’s electricity use and its utility’s tariff, along with other factors that can affect rates.

Who pays for new power plants and grid upgrades?
Utilities may propose investments to serve expected data-center demand, while regulators decide which costs can be recovered from which customer classes. The U.S. Department of Energy’s January 2025 technical brief identifies fair cost allocation, risks from underused investments, and reliability as large-load rate-design concerns.
- Costs assigned to the large customer: Dedicated connection facilities and incremental system upgrades can be charged directly to the data center, depending on the applicable tariff and regulatory rules.
- Costs shared through rates: Some generation or network investments may be recovered across broader customer groups. Whether that is appropriate depends on who benefits and which customers caused the need.
- Costs left behind if plans change: If a utility builds for a proposed facility that never opens or operates at the expected scale, the investment may be underused. The unresolved question is who bears that cost.
Forecast accuracy matters because utilities may plan around multiple proposed facilities, while some connection requests may be speculative or duplicate. The International Energy Agency’s 2025 Energy and AI report discusses the possibility that costs associated with such requests could be socialized. It also reports an ACER 2024 general-case estimate that a 10% overestimate of demand is associated with a 10% increase in total grid costs. That is not a data-center-specific estimate or a prediction for a particular utility.

Which protections and regulatory actions matter?
There is no single nationwide tariff described in the DOE brief as the answer. The relevant protections are the terms regulators require of large loads and the way utilities document and allocate costs.
- Cost-causation rules and transparent tariffs: Make clear which connection and system-upgrade costs are assigned to the large customer and which are shared.
- Long-term commitments and financial assurances: Minimum bills, capacity commitments, collateral, or termination payments can help protect other customers if a project scales back after infrastructure is built.
- Coordinated construction and load ramp-up: Matching a facility’s growth with the delivery of power infrastructure can reduce the risk of building too early or arriving without adequate supply.
- Flexible demand: Large loads that can shift or curtail some consumption may give grid operators more options in constrained conditions.
On June 18, 2026, the Federal Energy Regulatory Commission (FERC) directed all six regional grid operators under its jurisdiction to justify existing tariffs or propose reforms. The proceedings cover issues including cost shifting and transparency, co-location and behind-the-meter generation, flexible transmission service, interconnection studies, and generation adequacy. They are federal wholesale and transmission proceedings; state regulators retain authority over retail rates. The orders do not establish that household bills have fallen.

FERC had also raised a specific concern in a PJM co-location proceeding: that the tariff did not appear to sufficiently specify rates, terms, and conditions for co-located large loads. That identifies a regulatory issue, not proof that a particular household has paid a data-center surcharge.
A 2026 House committee report describes a proposed standard for covered large-load customers to pay full incremental generation, transmission, and distribution upgrade costs and provide financial assurances. Its amended proposal uses a threshold of at least 100 MW at a single data-center facility. The report is legislative committee material; it should not be treated as proof of an enacted nationwide requirement.
What to check in your own utility territory
A national study cannot establish why an individual household’s bill changed. To assess whether data-center growth could be relevant locally, start with the utility and regulator that set or review the applicable rates.
- Separate usage from price: Compare kilowatt-hours used and the rate or charges applied across bills. A higher total bill can reflect more consumption as well as a rate change.
- Identify your utility’s structure: Note whether it is investor-owned, publicly owned, or a cooperative, and how generation is regulated in your state. The MIT working paper reports different average effects across these categories, but those findings do not determine your utility’s outcome.
- Look for local large-load proposals: Check utility rate-case materials, regulator dockets, and utility planning documents for proposed data centers, load forecasts, generation plans, and transmission or distribution upgrades.
- Read the proposed cost terms: Look for who pays dedicated and incremental upgrade costs, whether minimum bills or collateral apply, and what happens if the facility is delayed, downsized, or canceled.
- Check timing and flexibility: See whether power supply and grid upgrades are expected to be available before the load arrives, and whether the large customer can curtail demand during constrained periods.
Other system costs—including fuel and generation expenses, grid modernization, plant retirements, and wildfire mitigation—can also affect rates. The national evidence summarized here does not quantify how much each factor contributed to a particular household’s recent bill.
