  • Gas Leads PJM’s Reopened Interconnection Queue at 106 GW

    Gas Leads PJM’s Reopened Interconnection Queue at 106 GW

    PJM Interconnection, the grid operator serving the largest electricity market in the United States, has reopened its interconnection queue — the formal waiting line new power plants must join before they can connect to the grid — and gas-fired generation leads the intake at 106 gigawatts (GW), according to an April 30, 2026 report by Utility Dive. The queue had been closed to new entrants for years while PJM worked through a massive backlog under reformed study rules.

    Executive Summary

    The reopening of PJM’s queue is one of the most consequential grid events of the decade for the data-center industry. PJM’s territory — spanning 13 states and the District of Columbia, including the Northern Virginia corridor that hosts the world’s densest concentration of data centers — has been the epicenter of the load-growth crunch. For years, developers of new generation could not even get in line, while demand forecasts climbed relentlessly on the back of AI and cloud expansion.

    That 106 GW of gas-fired capacity leads the new intake is the headline signal: developers are betting that dispatchable, fuel-based generation is what the market will pay for. For context, 106 GW of proposed gas alone approaches the scale of PJM’s entire historical peak load — a striking statement of intent, even acknowledging that interconnection requests are proposals, not power plants, and that historically only a fraction of queued projects reach commercial operation.

    The Queue Reopens Into a Seller’s Market

    An interconnection queue is the study pipeline through which a grid operator evaluates whether a proposed generator can connect safely and what network upgrades it must fund. PJM froze new entries while it transitioned from a first-come, first-served process — which had become clogged with speculative projects — to a clustered, first-ready, first-served model. The reopening is therefore a pressure release: years of pent-up development interest arriving all at once.

    The market these projects are entering is unusually favorable to generators. PJM’s recent capacity auctions have cleared at elevated prices, reflecting tightening reserve margins as older coal and gas plants retire faster than replacements arrive and as data-center load grows. High capacity prices are precisely the signal designed to attract new steel in the ground — and 106 GW of gas proposals suggests the signal is being heard.

    Why Gas Leads — Economics, Not Ideology

    Gas-fired turbines dominate this intake for practical reasons. They are dispatchable — able to run on demand rather than when the weather cooperates — which is what capacity markets and 24/7 data-center loads reward most. They site on relatively small footprints near existing gas pipelines and transmission. And developers can point to a revenue stack (capacity payments, energy sales, and potentially direct contracts with large loads) that pencils today.

    But the gas wave faces its own bottlenecks. Turbine manufacturers are reporting multi-year order backlogs industry-wide, EPC (engineering, procurement, and construction) labor is scarce, and gas pipeline expansion in parts of PJM’s eastern footprint has historically faced permitting resistance. Proposing 106 GW is easy; procuring turbines, pipe, and crews for even a fifth of it is the hard part. The queue position is now arguably the cheapest asset in the whole development chain.

    What This Means for Data-Center Developers

    For hyperscalers and colocation operators stuck in multi-year utility interconnection waits, a generation-heavy queue is cautiously good news: more supply eventually means faster load interconnection and less severe capacity-price escalation. It also strengthens the case for co-location deals, in which a data center sites directly alongside a new plant and contracts for its output — a structure regulators in PJM have been actively wrestling with.

    The timing mismatch remains the industry’s core problem. Data centers can be built in 18–24 months; a new combined-cycle gas plant typically takes four or more years from queue entry through studies, permitting, and construction. Even under PJM’s reformed process, the bulk of this 106 GW cannot plausibly serve load until late this decade. Buyers planning capacity for 2027–2028 should not count on this queue cycle to bail them out.

    The Decarbonization Tension Nobody Should Ignore

    A gas-led buildout sits uneasily beside the carbon-neutrality pledges of the very customers driving the demand. Most major cloud providers maintain public net-zero or carbon-free-energy targets, and a decade of gas additions in PJM would make those targets harder to reconcile with grid reality — unless paired with offsets, carbon capture, or an eventual nuclear and storage wave. The honest framing is that the market is prioritizing reliability and speed-to-power first and emissions second. Whether that ordering persists will depend on state policy in PJM’s footprint, federal rules, and how loudly corporate energy buyers push back through their procurement.

    Background

    PJM Interconnection grew out of a 1927 power pool among Pennsylvania and New Jersey utilities and today operates the largest wholesale electricity market in the United States. Its territory contains Northern Virginia’s “Data Center Alley,” which by itself consumes more data-center power than most countries. Over the past several years PJM became the poster child for the interconnection bottleneck: thousands of proposed projects — predominantly renewables in earlier cycles — languished in multi-year study backlogs, prompting a federally approved overhaul of its queue process and a temporary halt to new applications.

    The reopening lands amid record demand forecasts, plant retirements, and capacity prices that have drawn political scrutiny across PJM’s member states. The resource mix of this new intake — and how much of it survives to construction — will shape the region’s reliability, emissions trajectory, and data-center growth capacity into the 2030s.

  • PJM Moves to Rein In Data Center Demand on the World’s Busiest Grid

    PJM Moves to Rein In Data Center Demand on the World’s Busiest Grid

    PJM Interconnection — the regional grid operator serving 13 states and the District of Columbia, including Northern Virginia’s “Data Center Alley,” the densest concentration of data centers on Earth — is taking steps to rein in data center electricity demand, according to reporting from public broadcaster WHRO published April 20, 2026. The move signals that the operator of the world’s most data-center-heavy grid no longer treats hyperscale load growth as something to be absorbed without conditions.

    Executive Summary

    The significance here is less any single rule than the direction of travel. PJM is the largest wholesale electricity market operator in the United States, coordinating power for roughly 65 million people, and its territory hosts the global capital of the data center industry. For most of the past decade, the operating assumption in that territory was that if you could buy land and fiber, the grid would eventually follow. A grid operator moving to constrain or condition data center demand inverts that assumption.

    For the infrastructure industry, this matters in two ways. First, it converts power from a procurement line item into a gating factor: projects in PJM territory may increasingly be shaped by what the grid operator will allow, and on what timeline, rather than purely by developer ambition. Second, it sets a precedent. PJM’s rules and market designs are watched — and often copied — by other regional operators facing their own waves of AI-driven load requests. What PJM does about data centers rarely stays in PJM.

    The Grid Operator Blinks First

    A regional transmission organization (RTO) like PJM does not generate power or build data centers; it runs the wholesale market and keeps supply and demand in balance across its footprint. Its core legal obligation is reliability. When such an operator starts “taking steps to rein in” a category of demand, it is effectively saying that the pace of load requests has begun to strain its ability to guarantee that balance. That is a notable admission from the operator whose territory — anchored by Loudoun County, Virginia — handles more data center load than any comparable grid in the world.

    The economic backdrop makes the move legible. PJM’s recent capacity auctions — the mechanism through which it pays power plants to be available in future years — have cleared at sharply higher prices, with data center growth widely cited as a principal driver. Those costs flow through to every ratepayer in the footprint, not just the data centers causing the growth. Political and regulatory pressure to distinguish between speculative interconnection requests and real projects, and to make large loads bear more of the costs they create, has been building accordingly.

    From Land-and-Fiber to Power-First Siting

    If the grid operator for the world’s largest data center market is imposing limits, the site selection calculus changes for everyone downstream. Developers who counted on Northern Virginia’s unmatched fiber density and cloud ecosystem now have to weigh whether a grid connection will arrive on a bankable schedule. That logic has already been pushing projects toward secondary markets — and toward on-site or contracted generation that reduces dependence on the shared grid. Constraints in PJM accelerate both trends.

    There is also a sorting effect within the industry. Well-capitalized hyperscalers and established operators can absorb longer timelines, post larger financial commitments, and negotiate directly with utilities and generators. Thinly financed projects that were effectively options on future power — reserving grid capacity they might never use — are the natural target of any tightening. To the extent PJM’s steps separate firm demand from speculative demand, the result could be a healthier queue, even if headline growth numbers shrink.

    Reliability, Ratepayers, and the Politics of AI Load

    The uncomfortable center of this story is cost allocation. Electricity markets were not designed for single customers that show up requesting the load of a mid-sized city. When capacity prices rise to meet that demand, households and small businesses share the bill, and state regulators and legislators hear about it. A grid operator that visibly disciplines data center demand is, among other things, managing its own political legitimacy across 13 states with very different attitudes toward hosting the AI build-out.

    For the data center industry, the fair response is not to dismiss the concern but to engage on mechanism design: rules that require demonstrated financial commitment, that pay large loads for flexibility (curtailing during grid stress), and that let them bring their own generation can protect reliability without rationing growth. The risk, from the industry’s side, is blunt instruments — caps or moratoria that stall real projects along with speculative ones. Which kind of instrument PJM has chosen is the central question the reporting raises.

    Background

    PJM Interconnection grew out of one of the world’s oldest power pools, dating to 1927, and today runs the largest wholesale electricity market in the United States. Its footprint includes Northern Virginia, where cheap land, dense fiber routes, and proximity to federal and internet-exchange infrastructure made Loudoun County the global capital of the data center industry over the past two decades. That concentration was long a point of regional pride and tax revenue; the AI boom has turned it into a grid-planning challenge, as power demand in the region — flat for years — began climbing steeply on the back of hyperscale computing.

    By 2026 the tension was visible on ratepayer bills and in regulatory dockets: PJM’s capacity auction prices had risen sharply with data center growth cited as a key driver, and policymakers across its 13-state footprint were debating who should pay for the infrastructure the AI build-out requires. PJM’s move to rein in data center demand is the market operator’s entry into that debate.
