Power and permits are deciding where America's data centers can build

America's data-center expansion has become a construction program for electricity supply as well as computing facilities. During 2026, developers paired enormous server campuses with dedicated generation, transmission upgrades and improvements at existing nuclear plants. Governments simultaneously tightened the conditions for permitting and connecting those loads.

That combination is changing the work available to electrical contractors. A campus can create demand for cable, switchgear and commissioning inside its buildings while also requiring years of utility construction before its full computing capacity can operate. State permitting decisions and the terms of electric service increasingly determine when those packages can proceed.

Three decisions show the scale of the change through October 18: New York's July permitting moratorium, Texas's September permit directive, and FERC's October rejection of most of PJM's proposed framework for new large loads. Their scopes differ, and each matters to a different part of a project's delivery schedule.

New York and Texas put conditions on the next approvals

New York's Executive Order 62, signed July 14, directs the Department of Environmental Conservation to hold covered construction and expansion applications that had not been determined complete before the order. The hold lasts until the Department of Public Service submits its final generic environmental impact statement report and findings.

The order covers defined facilities capable of consuming at least 50 MW, with exclusions for facilities primarily used for manufacturing, research, education or medical care. It expressly excludes local-government permits from this provision. Its effect therefore depends on a project's facility type, application status and required state approvals. Describing every New York construction site as shut down would erase those distinctions.

Texas took a separate route on September 21. In a signed letter to the Texas Commission on Environmental Quality, Governor Greg Abbott directed the agency to pause permits related to data-center projects until ERCOT completes its review. He also directed other state agencies to await information from the electricity and water audits before advancing regulatory approvals.

The letter calls for scrutiny of grid reliability, water use and who pays for electrical infrastructure. It required a TCEQ compliance update on October 19, one day after this article's cutoff. It does not itself establish that every previously permitted Texas project stopped construction. Its discussion of eliminating financial incentives concerns future legislative action.

For a project awaiting an affected approval, these decisions add a dependency to the construction schedule. An owner's target opening date cannot resolve that dependency by itself. The records reviewed here establish the directives and their scope; they do not establish a common revised completion date for every affected campus.

FERC accepted visibility into PJM's loads, while rejecting the proposed service package

PJM, the regional grid operator, spent 2026 trying to reconcile rapid load growth with the resources available to serve it. Its January 14 forecast explanation already showed a need to scrutinize proposed projects: near-term growth through 2032 was lower than in the previous forecast after stronger vetting of commitments and prospective loads. Announced demand and delivered demand follow different timelines.

On August 13, PJM filed a more consequential proposal. Its Interim Resource Adequacy Service, or IRAS, would have exposed certain new large loads to mandatory curtailment when sufficient new capacity had not been designated for them. Linked provisions addressed bringing new generation and the treatment of those loads in the capacity market.

The October 9 FERC order, 197 FERC ¶61,019, accepted only a Large Load definition and a Large Load Registry, effective October 12. The definition uses a cumulative peak threshold of 50 MW and reaches large industrial loads beyond data centers.

FERC rejected the remaining package, including IRAS, the linked arrangements for bringing new generating capacity and the separate proposed New Large Load definition. Its objections included the boundary between wholesale and retail regulation and insufficient justification for key provisions. It required a compliance filing within 30 days and gave guidance for a possible revised proposal.

That result matters to construction planning. The accepted registry gives PJM better information for forecasting and system planning. It does not grant an individual campus permission to interconnect. And the rejected proposal cannot be treated as an operative federal requirement that every new PJM data center must bring its own generation or accept the proposed curtailment terms.

The underlying need for supply remains. The October decision determines which parts of this particular proposal advanced; it does not deliver the power plants, transmission capacity or local service agreements required by a new campus.

Developers are adding power projects to the campus plan

Abilene, Texas, illustrates the physical response. On March 27, Crusoe announced an adjacent campus for Microsoft with land clearing and site preparation underway. Its two buildings are each designed for 336 MW of critical IT load. A separate 900 MW onsite power plant, paired with battery storage, is part of the plan. First-building energization was targeted for mid-2027.

Those numbers describe different equipment: 672 MW of combined critical IT load and 900 MW of generation are not additive measures of computing capacity. Their importance to construction is the expanded scope. The development includes both server buildings and a substantial power installation, with delivery of one dependent on the other.

Louisiana shows the same issue at utility scale. Entergy's March 27 Meta agreement and infrastructure plan described seven new combined-cycle gas plants totaling more than 5,200 MW, approximately 240 miles of 500 kV transmission, batteries at three locations and nuclear uprates. The company said Meta would cover the infrastructure costs associated with the plan.

Entergy's regulatory record identifies the March 27 application as docket U-37882. These are proposed infrastructure investments, with their own approval and construction process. A campus expansion announcement cannot be read as evidence that all the supporting plants and lines are already approved or built. Our Richland Parish project coverage describes the local campus work and procurement separately.

In Wyoming, AEP's October 14 announcement outlined an approximately $4 billion, 702 MW Bloom fuel-cell generation project near Cheyenne under a 20-year Google power purchase agreement. AEP and its partners planned to begin construction in 2026 and reach full operation by the end of 2028. That is a substantial new electrical project, with a delivery horizon extending well beyond the announcement.

Google and Constellation chose another route in PJM. Their October 6 agreement supports 890 MW of planned uprates at 11 existing nuclear units across six sites in Illinois, Pennsylvania and New Jersey. The first uprate is expected in 2028. The described work includes turbines, steam generators and digital controls. A separate 2,700 MW supply agreement concerns existing output and adds no new generation by itself.

These approaches place work in different locations. Dedicated generation can sit beside a campus; utility transmission can extend across a region; nuclear modernization occurs at existing plants. For electrical employers, the buildout's geography reaches beyond the city named in the data-center announcement.

Some proposed work will leave the pipeline

The effect of permission is visible in an actual withdrawal. In a March 31 letter to Monterey Park, California, HMC StratCap 1977 Saturn LLC withdrew its data-center application, citing the city's moratorium and proposed ban as conditions unfavorable to development. The city subsequently adopted Ordinance 2278 on May 6, prohibiting data centers with stated exceptions, including ancillary server rooms.

One withdrawal cannot measure national cancellations. It does demonstrate why a proposed campus, a permitted project, an active construction site and an energized facility should carry different weight when assessing future work.

The electrical construction consequences of this year's data-center expansion are substantial. They also depend on a sequence of real decisions: approval of the facility, an acceptable service arrangement, deliverable supply, and construction and commissioning of the required systems. The strongest evidence of coming work combines those decisions with a defined physical scope and a dated delivery milestone.

Reporting covers decisions and announcements available through October 18, 2026. Project scopes and delivery targets are attributed to their owners; later approvals and field progress can change the schedule.
