Data Center Growth Continues, but Power and Permitting Constrain Delivery
of Play
The buildout remains active rather than demonstrably stalled, although access to power and jurisdiction-specific approvals continue to separate planned capacity from deliverable facilities. New reporting quantifies substantial exposure to Texas’s grid-connection audit and identifies a large utility-backed generation commitment, but neither establishes how quickly capacity will come online. Microsoft’s longer facility-life estimate changes reported cost allocation, not physical infrastructure availability.
What's New?
Expansion continues under uneven delivery constraints
US capacity under construction reportedly rose 48% from December 2025 to June 2026, supporting the prior assessment that growth has not broadly halted. Power access remains a constraint: Oracle’s planning prioritizes securing power before final hardware choices. Construction capacity is not yet operating capacity.
Approval restrictions vary by jurisdiction and mechanism
Texas’s connection audit creates substantial pipeline uncertainty, while local governments are developing distinct zoning controls: Lima paused approvals and Tulsa has proposed size-based rules. These measures should not be treated as interchangeable bans or evidence of a sector-wide relocation.
Power procurement increasingly entails generation delivery
Alphabet’s Cheyenne supply agreement supports a substantial gas-generation investment. Such arrangements can address power needs, but committed investment and contracted supply are distinct from completed, operating generation.
What's Changed?
Texas audit exposure is now more concretely quantified
New reporting puts nearly 49.8 GW of projects seeking grid connections within the audit’s scope. That sharpens the scale of potential exposure relative to the prior assessment, but does not establish that this capacity will be delayed or lost. The separate environmental-permit directive’s application remains unresolved.
Alphabet contract supports a major generation investment
Reporting identifies a Black Hills agreement to supply Alphabet’s Cheyenne data center with 590 MW through 2048, supporting $1.8 billion in investment in 564 MW of new gas generation. This is a more concrete power arrangement than a general power-first strategy, though completion and delivery timing remain unconfirmed.
Microsoft lengthens its facility accounting life
Microsoft reportedly increased its estimated data-center useful life from 15 to 25 years, spreading facility costs over a longer period. This changes reported cost allocation; the evidence does not establish lower construction costs or longer physical service lives.
What Matters?
Pipeline exposure is not the same as a construction downturn
The earlier rise in capacity under construction reinforces the prior view of constrained rather than halted expansion. The Texas audit could affect a large prospective pipeline, but the available evidence does not show how much will be delayed or whether the June construction trend has since reversed.
Large power contracts shift the delivery problem
The Cheyenne agreement strengthens the case that data-center demand can underpin new generation investment. It does not eliminate execution risk: the new supply must still be built and delivered, and the evidence does not establish how infrastructure costs are allocated among customers.
Reported facility costs may become less comparable
Microsoft’s longer useful-life assumption spreads costs over more years, making reported period costs less directly comparable with those under the prior assumption. It is not evidence that capital intensity or financing pressure has eased.
What's Next?
Resolve Texas audit and permit scope
Watch which connection applications advance, are delayed or are removed from the audit, and whether the separate environmental-permit directive applies to pending and off-grid projects. Actual dispositions would distinguish large exposure from realized capacity loss.
Test whether contracted power becomes deliverable
Watch permitting, construction and commissioning of Black Hills’ generation, as well as tariff and cost-allocation details. Completion would strengthen confidence in the supply arrangement; delays or unresolved cost responsibility would expose continuing delivery and ratepayer risks.
Watch whether local controls change actual project delivery
Tulsa’s zoning changes remain a proposal. Watch whether they are adopted and whether they alter approvals or available sites; compare that with Lima’s eventual replacement standards. Binding effects would strengthen the assessment that local controls are shaping siting, rather than merely adding review.
