FERC's Rejection of PJM Interconnection Plan Puts Virginia Data Centers at Risk

Executive Summary

FERC's decision to reject the majority of PJM's large load interconnection plan deals a direct blow to data center developers pursuing projects in Loudoun County, Virginia — the most data center-dense geography in the world. Developers already in PJM's interconnection queue face elongated timelines, repriced risk, and, in some cases, project viability questions that weren't there six months ago. Established operators with existing interconnections hold a structural advantage; new entrants and speculative developers bear the most exposure. The InfraSale takeaway: regulatory risk is now a first-order variable in Virginia site underwriting, not a footnote.

What Happened

On October 12, 2026, FERC rejected the bulk of PJM Interconnection's proposed framework for handling large load interconnection requests — the mechanism through which data centers, hyperscalers, and other high-draw facilities formally connect to the regional grid. The ruling applied to PJM's service territory, which covers 13 states and the District of Columbia, with Loudoun County, Virginia, sitting near the center of its most constrained transmission corridor.

The rejection means that PJM must go back and revise its approach to processing large load requests. Projects pending in that queue — including an unspecified number of data center developments in Northern Virginia — now face procedural limbo while PJM reformulates its plan and resubmits it to FERC for approval. The clock on those interconnection studies resets or stalls depending on where each project sits in the queue.

Specific project names, MW figures, and affected developers were not disclosed in the source reporting. What is clear is that the ruling carries immediate operational consequences for developers who had structured timelines, financing, and pre-leasing arrangements around expected interconnection milestones.

Why This Matters

Virginia's data center corridor — anchored in Loudoun County, where more than 35 million square feet of data center space has been developed — runs almost entirely on PJM's transmission infrastructure. Any disruption to how PJM processes large load requests doesn't just slow individual projects; it creates systemic uncertainty across the regional pipeline.

Industry context: Interconnection queue timelines in PJM have already stretched to 4–6 years in congested areas under normal conditions. A FERC rejection that forces PJM to revise and resubmit its framework adds months to that baseline at minimum, potentially longer if FERC pushes back on revisions. For developers with land under contract and pre-lease commitments to hyperscaler tenants, every month of delay carries real dollar costs.

The decision also signals that FERC is not satisfied with how regional grid operators are managing the surge in large load demand — a surge driven almost entirely by AI infrastructure buildout and cloud expansion. This isn't a one-off procedural dispute. It reflects a structural mismatch between the speed at which data center demand is growing and the pace at which grid governance frameworks can adapt.

The ripple effects extend to capital markets. Lenders and equity partners underwriting data center projects in Virginia will now require more conservative interconnection contingency assumptions, which compresses project returns and may push some marginal deals below threshold.

Power & Interconnection Impact

The immediate grid-level consequence is increased uncertainty around available interconnection capacity in already-congested Northern Virginia substations. Dominion Energy Virginia, the incumbent utility serving most of Loudoun County, has been managing unprecedented load growth requests. FERC's rejection adds a regulatory layer on top of existing physical constraints.

Assumption: Projects that had secured conditional interconnection agreements or early-queue positions may retain some priority, but the procedural reset creates legal ambiguity that developers will need to resolve with PJM and legal counsel before assuming their queue position is intact.

Data centers facing interconnection delays will need to evaluate alternatives: distributed generation, behind-the-meter power (gas, nuclear microreactors, or large-scale storage), or co-location with existing grid-connected industrial sites. None of these are fast or cheap substitutes for a clean transmission interconnection. Power purchase agreements tied to interconnection milestones will also need renegotiation in some cases, adding counterparty risk to an already complex picture.

Future load growth projections for the PJM territory — some forecasts have cited tens of gigawatts of new data center load through 2030 — now carry a wider error bar. FERC's intervention is a signal that the current framework cannot absorb that volume without structural reform.

Land, Zoning & Permitting Impact

Permitting timelines in Virginia are partially indexed to interconnection status. Local jurisdictions, including Loudoun County, have increasingly conditioned data center approvals on demonstrated utility coordination. If interconnection milestones slip, the downstream permitting calendar slips with them.

Land acquisition strategies will need adjustment. Sites that were valued on the basis of near-term interconnection availability may require downward repricing or deal restructuring. Sellers holding powered or transmission-adjacent land in Loudoun and adjacent Prince William County retain leverage, but buyers will be negotiating harder on contingency language and closing conditions tied to interconnection clarity.

Industry context: Some Virginia counties have already enacted or considered temporary moratoria on data center approvals in response to infrastructure strain. A prolonged FERC-driven queue disruption could accelerate that conversation, particularly in jurisdictions where community opposition to data center density is already building.

Zoning and special use permit frameworks may also evolve. If the grid cannot accommodate new large-load facilities on expected timelines, local planners will face pressure to phase approvals more tightly to available infrastructure capacity — a shift that would further constrain development timelines for new entrants.

Investment Takeaway

Queue position is an asset. Projects with early, confirmed positions in PJM's interconnection queue are now worth more. Buyers should seek to acquire or partner into projects that already hold that position rather than starting from scratch.
Timeline assumptions need revision. Any pro forma built on a sub-24-month interconnection timeline for a new Virginia site should be stress-tested against a 36–48 month scenario and potentially longer.
Behind-the-meter power is gaining value. Data center developers who have invested in on-site generation capacity or secured bilateral power arrangements are partially insulated from queue disruption. That asset characteristic is now a pricing premium.
Capital reserves need to increase. Lenders and equity partners should factor in the cost of carry during extended delays — land hold costs, predevelopment expense burn, and potential lease penalty exposure with hyperscaler tenants.
Diversification outside PJM deserves a second look. Markets like MISO, ERCOT, and SPP present different regulatory environments and queue dynamics. Assumption: Some capital that was oriented toward Virginia may begin evaluating Midwest and Texas alternatives more seriously.

InfraSale Market Angle

For data center developers and site selectors actively working the Virginia market, this ruling demands an immediate project audit. Every site in your pipeline with an open interconnection study or pending queue application needs to be reviewed against PJM's revised process once it is resubmitted and approved by FERC.

Landowners holding acreage near Dominion substations in Loudoun and Prince William counties should expect buyer caution to increase in the near term. That doesn't mean deals stop — it means buyers will demand more certainty on utility coordination before closing. Sellers who can provide documented utility engagement and load feasibility studies will move faster than those who cannot.

Investors evaluating Virginia data center exposure should differentiate sharply between established operators with operational interconnections and developers who are still in the queue. The former group benefits from regulatory barriers to new competition. The latter group carries the full weight of this ruling on their project economics.

FAQ

How does FERC's decision impact data center projects in Virginia?

Projects in PJM's interconnection queue face procedural delays while PJM revises and resubmits its large load framework for FERC approval. Developers who had structured financing, leasing commitments, or construction timelines around interconnection milestones will need to reassess those schedules, likely extending timelines by months or more and increasing carrying costs accordingly.

What should investors consider in light of this regulatory development?

Risk reassessment should start with interconnection status: projects with confirmed, early-queue positions are more defensible than those in early study phases. Capital models should incorporate extended timeline scenarios, increased contingency reserves, and the possibility that some projects in constrained Northern Virginia corridors may require alternative power sourcing to remain viable.

Are there alternative solutions for data centers facing interconnection delays?

Some developers are exploring behind-the-meter generation — including on-site gas, battery storage, and, in some cases, advanced nuclear concepts — to reduce dependence on utility interconnections. Others are evaluating co-location with existing grid-connected industrial or commercial sites that carry available capacity. Industry context: these alternatives carry their own cost, permitting, and lead-time burdens and are not drop-in substitutes for transmission interconnections.

Could this ruling affect land values near Loudoun County substations?

Powered land and substation-adjacent sites retain long-term value, but near-term buyer behavior will become more cautious and contingency-heavy. Sellers with documented utility engagement and demonstrated load feasibility are better positioned to close deals during the period of regulatory uncertainty.

Will other PJM markets outside Virginia face similar disruption?

The FERC ruling applies to PJM's entire territory, so data center developers in other PJM markets — including Ohio, Illinois, and New Jersey — face the same procedural uncertainty. Loudoun County is the most acute pressure point given its existing concentration of load growth requests, but the ruling's impact is regional in scope.
