Demand Remains Strong, but Power and Approvals Constrain Delivery
of Play
The prior assessment remains intact: data-center expansion is constrained by deliverable power and jurisdiction-specific approvals, not demonstrably halted. Digital Realty’s record leasing adds evidence of demand, while newly reported reliability findings highlight a separate coordination problem for large loads. Neither establishes how quickly new capacity will become operational.
What's New?
Demand persists alongside power-delivery constraints
Digital Realty’s record leasing supports continued demand, while Oracle’s power-first planning and Detroit’s reported transmission limitation illustrate why securing usable electricity can govern deployment. These examples do not establish the sector-wide pace of new operating capacity.
Approval constraints remain jurisdiction-specific
Texas permitting restrictions and Lima’s pause on approvals illustrate different controls, not a uniform ban. Their effects on project schedules and capacity remain uncertain.
What's Changed?
Record leasing strengthens the demand signal
Digital Realty reported $855 million in annualized base rent from quarterly leasing, a company record; interconnected bookings in the 0–1 MW category were 40% above their previous record. This strengthens evidence of demand but is not a measure of newly delivered capacity.
Reliability reporting identifies a large-load coordination gap
New reporting says NERC concluded that utilities and grid entities need direct data and coordination obligations for large computational loads. The evidence describes a finding, not an enacted requirement or a demonstrated change in grid capacity.
What Matters?
Demand and delivery remain distinct
Record leasing reinforces the prior view that constraints coexist with demand rather than prove a broad buildout halt. Power-first planning shows why signed business or a site strategy should not be equated with energized capacity.
Grid integration involves information as well as supply
NERC’s reported finding adds a reliability-planning dimension to the existing power constraint: inadequate facility data can complicate forecasting and coordination even before physical supply is considered. Direct obligations, if adopted, would not themselves create generation or transmission.
What's Next?
Resolve the Texas permitting exposure
The prior questions about the directive’s scope and reopening conditions remain unresolved. Watch for clarification of which pending and off-grid projects are affected, and for evidence of actual delays rather than merely exposed proposals.
Test whether grid policy changes obligations or costs
Watch whether NERC’s findings lead to enforceable coordination requirements and whether the proposed Senate permitting bill advances its transmission-cost provisions. The latter could alter project economics, but remains a proposal.
Measure power commitments against physical delivery
The existing delivery test remains open: watch for generation, transmission and interconnection milestones that turn power plans into usable supply, including who bears infrastructure costs. Continued reliance on dedicated generation would not by itself prove faster deployment.
