PJM Interconnection’s independent market monitor has concluded that AI-driven data center growth is reshaping the power markets it oversees, according to a June 2026 report from Data Center Knowledge. PJM operates the largest wholesale electricity market in the United States, coordinating the grid across 13 states and the District of Columbia for roughly 65 million people.

The finding matters because it comes from the market’s designated referee rather than from a vendor or developer: the monitor exists precisely to assess, without commercial interest, whether the market is functioning competitively — and it is now attributing a fundamental shift in that market to data center load.

Executive Summary

The headline is short but consequential: PJM’s market monitor — the independent body charged with policing competition in the nation’s largest electricity market — has identified AI data center growth as a force actively reshaping that market. For two decades, US grid planners worked in a world of essentially flat electricity demand, where efficiency gains offset economic growth. That assumption has broken, and PJM, whose footprint includes Northern Virginia’s Data Center Alley, is where it broke first and hardest.

When the market monitor says demand growth is ‘reshaping’ the market, it is signaling that data center load is no longer a forecasting footnote but a structural driver of prices, planning, and investment decisions. PJM’s recent capacity auctions — the mechanism that pays generators to be available years in advance — have produced record-setting results widely attributed in part to surging demand forecasts, and those costs flow through utility bills to every customer class.

For the industry, an independent confirmation of this shift cuts both ways. It validates the scale of the AI infrastructure build-out that developers have been describing. It also raises the stakes for how that growth is managed: who pays for new transmission and generation, how speculative interconnection requests are filtered from real ones, and whether supply can be added fast enough to keep reliability and affordability intact.

From Forecasting Footnote to Structural Force

The most important word in this story is ‘reshaping.’ Grid operators revise load forecasts constantly; what they rarely do is declare that the character of the market itself has changed. PJM’s service territory covers all or part of 13 states and DC, and it includes the densest concentration of data centers on the planet in Northern Virginia. When demand there grows, it does not simply add megawatts — it changes which power plants run, where transmission congestion appears, and how much capacity the market must procure years ahead.

An assessment from the independent market monitor carries different weight than one from PJM itself or from data center developers. The monitor’s role — in PJM’s case performed by an outside firm — is to evaluate market competitiveness and flag structural problems without a commercial stake in the outcome. Its reports are read closely by federal and state regulators. Framing AI data center growth as market-reshaping effectively puts the issue on the regulatory agenda, not just the industry conference circuit.

Capacity Markets, and Who Ends Up Paying

PJM runs a capacity market: generators are paid not only for the electricity they produce but for committing to be available during future peak periods. When demand forecasts rise sharply — as data center growth has caused them to — the market must procure more capacity against a supply base that has been shrinking as older coal and gas plants retire. Basic economics follows: tighter supply against higher demand means higher clearing prices, and PJM’s recent auctions have set records that state officials and consumer advocates have publicly protested.

Capacity costs are socialized across ratepayers, which is where the political friction originates. Households and small businesses in PJM states are seeing bill increases driven partly by demand they did not create. Expect the policy debate to center on cost allocation: large-load tariffs that require data centers to underwrite the infrastructure they trigger, minimum take-or-pay commitments, and rules for co-located or behind-the-meter arrangements where a data center pairs directly with a power plant. How those rules land will materially affect data center project economics in the region.

Winners, Losers, and the Speculation Problem

The near-term winners are clear: owners of existing generation in PJM, whose assets have been revalued by scarcity, and transmission developers with projects in flight. Data center operators with secured power — signed interconnection agreements and energized substations — hold an asset that is increasingly the scarcest input in the industry. The squeezed parties are late-arriving developers facing multi-year waits for grid connection, and energy-intensive industries competing for the same electrons.

The unresolved analytical problem is demand-forecast quality. It is widely acknowledged in the industry that developers file interconnection requests with multiple utilities for the same prospective project, meaning some portion of announced demand is duplicative or speculative. If markets procure capacity against inflated forecasts, ratepayers overpay; if forecasts are discounted too aggressively and the load shows up, reliability suffers. Distinguishing real load from phantom load is arguably the central technical challenge the monitor’s finding implies — and one the industry itself has an interest in helping solve, since credibility with regulators depends on it.

The Supply Response Is the Whole Game

High prices are a symptom; the cure is new supply, and here timelines diverge badly. A hyperscale data center can be built in roughly two to three years. New gas turbines face multi-year equipment backlogs, nuclear operates on decade scales, and renewables plus storage — often the fastest option — face their own interconnection queues and siting fights. Transmission, the connective tissue, is slower still.

That mismatch, more than any single auction result, is what ‘reshaping the market’ means in practice. It pushes data center operators toward creative structures: siting near existing generation, contracting directly for new-build power, investing in on-site generation, and accepting flexibility obligations — curtailing or shifting load during grid stress — in exchange for faster connection. For infrastructure providers, grid access has moved from a line item in site selection to the decisive variable.

Background

PJM traces its roots to a 1927 power pool between Pennsylvania and New Jersey utilities and has grown into the largest regional transmission organization in the US, dispatching power across 13 states and DC. An independent market monitor oversees its wholesale markets and publishes regular assessments of their competitiveness and health. For most of the 2000s and 2010s, PJM — like the rest of the US grid — planned around flat demand, as efficiency gains offset economic growth.

That era ended as cloud and then AI data center construction accelerated, concentrated in PJM territory around Northern Virginia. The region’s recent capacity auctions have produced record-setting prices that drew objections from state officials and consumer advocates, putting data center load growth at the center of an escalating debate over grid reliability, cost allocation, and how fast new generation and transmission can be built.

On May 19, 2026, the U.S. Energy Information Administration (EIA) — the federal government’s independent energy statistics agency — published new commercial-buildings data showing that energy consumed by data center servers is growing across the nationwide commercial building stock. The finding lands in the middle of an intense public debate over how much electricity the AI build-out actually consumes.

The release matters less for any single number than for its source: this is federal survey data, not a vendor forecast, quantifying how server energy use has expanded within America’s offices, dedicated data centers, and the server rooms tucked inside ordinary commercial buildings.

Executive Summary

EIA’s announcement extends its commercial-buildings statistical program — best known through the Commercial Buildings Energy Consumption Survey (CBECS), the government’s long-running census-style study of how U.S. commercial buildings use energy — to document rising server energy consumption across the building stock. In plain terms: the computers doing the computing inside commercial buildings are drawing a growing share of those buildings’ electricity.

Why it matters: nearly every claim about the ‘AI power crunch’ to date has rested on private-sector estimates from consultancies, utilities, and technology vendors, each with its own methodology and, in some cases, its own commercial interest in the answer. A federal statistical agency measuring the same trend from building-level survey data gives regulators, utilities, and investors a common, disinterested baseline — the kind of number that ends up cited in rate cases, siting decisions, and congressional testimony.

For infrastructure operators, the direction of the data is unsurprising. The significance is that the growth is now visible across the commercial building stock — not only in purpose-built hyperscale campuses, but in the broader population of buildings that house servers.

Federal Numbers Change the Power Debate

Until now, the data center energy conversation has been dominated by projections — analyst decks, utility interconnection queues, and corporate sustainability reports. Projections are arguments; survey data is evidence. EIA’s commercial-buildings program measures what buildings actually consumed, which makes it the closest thing the industry has to a scoreboard. When a .gov dataset says server energy use is growing across the building stock, it becomes much harder for any side of the debate — boosters or critics — to dismiss the trend as hype or alarmism.

That cuts both ways. Utilities seeking rate recovery for grid upgrades, developers seeking permits, and efficiency advocates seeking standards will all now cite the same federal source. Expect this data to surface in state utility commission filings and local zoning fights, where the credibility of the underlying numbers is often the whole battle.

The Hidden Data Center Problem

The phrase ‘commercial building stock’ is doing important work in EIA’s framing. Public attention fixates on gigawatt-scale AI campuses, but a substantial slice of America’s server fleet has historically lived in less visible places: server rooms in office buildings, hospital basements, university closets, and small enterprise data centers. These embedded loads are dispersed, often inefficient, and poorly captured by headline hyperscale statistics.

Growth measured across the whole stock suggests the compute boom is not just a story of a few hundred giant facilities — it is diffused through the built environment. For the efficiency industry, that is a market signal: dispersed, aging server rooms are prime candidates for consolidation into professionally run colocation facilities, which typically achieve far better power usage effectiveness (PUE — the ratio of total facility power to the power that actually reaches computing equipment).

Winners, Losers, and the Grid in Between

The beneficiaries of officially documented demand growth are the companies positioned to serve it: colocation and cloud operators with contracted power in hand, transmission developers, and equipment suppliers across the cooling and electrical chain. Utilities gain justification for capital programs, though they also inherit the political risk of rising rates being blamed on data centers.

The exposed parties are energy buyers competing for the same electrons — manufacturers, electrified transport, and ordinary ratepayers — and any data center developer whose business case assumes cheap, quickly available power. Federal confirmation of demand growth strengthens the hand of grid planners who argue for building ahead of load, but it equally strengthens critics who ask whether that growth should pay its own way. The honest reading of EIA’s data is that it quantifies the trend without settling the policy argument.

Background

EIA has surveyed U.S. commercial buildings for decades through CBECS, producing the government’s authoritative picture of how offices, schools, hospitals, and other non-residential buildings consume energy. Data centers historically registered as a small but disproportionately energy-intensive slice of that stock — buildings that consume many times more electricity per square foot than a typical office.

The context shifted sharply after 2023, when large-scale AI training and inference drove a wave of data center construction and record utility interconnection requests, making data center electricity demand a national policy issue. Against that backdrop, federal measurement of server energy use across the building stock arrives as a reference point both industry and its critics have lacked.
