Seattle Ferguson, a student at Virginia Commonwealth University, stood before the state's utility regulators in late 2025 and told them that twenty dollars a month on her electricity bill might not sound like much to a CEO, but for her, it was massive. Retirees and government workers testified alongside her, opposing a proposed rate hike driven in large part by data centre expansion.

The same tension is playing out in multiple countries. Data centres require physical infrastructure, and that infrastructure consumes large volumes of electricity. The cost of upgrading grids to meet this demand is now appearing in household utility bills in Virginia, Ireland, and several other jurisdictions.

 

Data centre electricity demand is rising fast

The International Energy Agency's April 2026 report, Key Questions on Energy and AI, provides the latest figures. Global electricity demand from data centres grew 17 per cent in 2025. Demand from AI-focused facilities grew faster still, increasing 50 per cent in a single year. Both figures exceeded the 3 per cent growth in overall global electricity consumption.

The IEA says the largest technology companies' capital spending exceeded $400 billion in 2025, and spending by leading hyperscalers and neo-cloud firms is expected to rise sharply again in 2026. The combined capital expenditure of these firms now exceeds total global investment in oil and gas production.

💡The IEA projects global data centre electricity consumption will roughly double from 485 TWh in 2025 to 950 TWh by 2030, accounting for nearly 3 per cent of global electricity demand. Consumption from AI-specific facilities is expected to triple in the same period.

These projections are shaping utility planning, regulatory rate-setting, and household energy budgets in real time.

 

Virginia's new rate class for data centers

Northern Virginia hosts the largest concentration of data centres in the world. Dominion Energy serves roughly 450 of them. Some forecasts suggest Virginia's electricity demand could nearly triple by 2040, with data centre expansion as the primary driver.

In November 2025, the Virginia State Corporation Commission approved a new Dominion Energy rate structure that raised typical residential bills by $11.24 per month in 2026, with an additional $2.36 increase slated for 2027. The SCC also created a new rate class, GS-5, for customers demanding 25 megawatts or more. Starting in January 2027, these large users, primarily data centres, must sign 14-year contracts and pay a minimum of 85 per cent of their contracted transmission and distribution demand, regardless of actual usage.

The purpose was to prevent the costs of grid buildout from being passed to residential ratepayers. Peter Anderson, director of state energy policy at the nonprofit Appalachian Voices, said following the decision: "Residential customers should not be subsidising these wealthy companies, and Virginians are relying on the commission to address these fundamental questions of fairness."

💡PJM's 2025-2026 capacity auction cleared about 833 per cent above the prior year, in a market shaped by tighter supply-demand conditions, rising large-load forecasts that include data centres, and rule changes. In Virginia rate-case testimony cited by news coverage, a witness said data-centre expansion could add about $22 billion to Dominion's spending over 15 years if current plans are realised.

Data centres contribute tax revenue and employment. They also require new generation capacity and grid upgrades, and those costs must be recovered through rates. Until now, most of that recovery has come from the general ratepayer base.

 

Ireland's policy response

Ireland presents a more advanced version of the same challenge. Data centres now consume more than a fifth of the country's total metered electricity, up from 5 per cent in 2015. In Dublin, the share has reached 79 per cent, according to analysis by the Oeko-Institute.

Grid strain pushed regulators into a de facto moratorium on new data centre connections in 2021. Projects stalled for more than three years while the government sought to balance its role as a European tech hub with the physical limits of its electricity system. Ireland procured temporary emergency generation as part of its security-of-supply response. Public commentary has linked grid and backup-power costs to higher consumer bills, though the precise scale of the household impact remains difficult to confirm without primary documentation.

Irish Labour TD Ciarán Ahern said his party had "long called for a moratorium on new data centres until we can be sure they will not strain the grid, inflate household bills or derail climate targets."

In December 2025, Ireland's CRU replaced the de facto connection freeze in constrained areas with a stricter connection policy for new large data centres. Any data centre seeking a grid connection must now install on-site generation or battery storage to match its full import capacity. Operators must also source 80 per cent of their annual demand from renewable energy within six years. The government's Large Energy User Action Plan, approved in January 2026, pushes new development away from congested Dublin and toward regional "green energy parks" co-located with offshore wind.

Ireland's approach may offer a template for other jurisdictions. The policy requires data centres to install on-site generation or storage and to show they will not destabilise the grid.

 

How the technology sector is responding

Major technology companies have begun addressing the issue publicly. In January 2026, Microsoft President Brad Smith announced a five-point plan for community engagement around data centres: "Our pledge to each of these communities is that we will pay our way as a company, to ensure that our data centres don't increase your electricity prices."

Microsoft is committed to requesting higher commercial rates from utilities, investing in local water systems, and paying full property taxes. Other hyperscalers have made similar commitments, though with less specificity. The IEA says data-centre PPAs accounted for more than 30 per cent of total corporate renewable PPA volume in 2025. Separately, the pipeline of conditional offtake agreements between data centre operators and small modular reactor developers has grown from 25 gigawatts at the end of 2024 to 45 gigawatts today.

💡By 2027, a single server rack in an advanced AI data centre could have a peak power demand equivalent to 65 households. Between 2020 and 2025, the power density of AI servers increased elevenfold, and a further fourfold increase is expected by 2027.

Whether these commitments translate into fair outcomes depends on regulatory authority and rate structures. Enforcement mechanisms vary across jurisdictions, and voluntary pledges do not substitute for binding rate rules.

 

The challenge extends beyond individual markets

Virginia and Ireland are the most prominent cases, but the pattern is broader. Amsterdam imposed a data center moratorium in 2019. Frankfurt introduced new development regulations in 2022. In Texas, data centers add to residential cooling loads during summer peaks in a deregulated market. In Southeast Asia, where data center electricity demand is expected to more than double by 2030, coal still generates much of the power.

IEA Executive Director Fatih Birol said in the agency's April 2026 report: "There is no AI without energy, and countries that provide secure, affordable and rapid access to electricity will be one step ahead." He added that while AI remains an "energy taker," it is also becoming "an energy maker," contributing to investment in next-generation nuclear and long-duration energy storage.

Data centres support services used by billions of people daily. The policy question is not whether they should exist but how their expansion interacts with energy systems and who bears the associated infrastructure costs.

 

Emerging policy approaches

Virginia's new rate class establishes the principle that large industrial loads should bear costs proportional to the infrastructure they require. Ireland's on-site generation and renewable sourcing requirements create a financial incentive for data centres to contribute to grid capacity rather than simply draw from it. The European Commission is preparing a data-center rating scheme and energy-efficiency package, with adoption scheduled for Q2 2026, which could improve transparency if finalised as proposed.

No single measure resolves the cost-allocation problem. Taken together, these policies represent a shift from accommodating data centre growth to conditioning it on infrastructure investment and grid contribution.

Rising electricity demand from data centres is influencing rate structures in multiple jurisdictions. The companies building AI infrastructure have the resources to fund grid upgrades. Measures that shift costs to large users, mandate on-site generation and ensure renewable procurement can help protect household energy budgets. The regulatory frameworks taking shape in Virginia and Ireland will indicate whether that protection is durable.
