Supply-chain research brief
Research generation, transformers, switchgear, cooling, interconnection, and electrical construction constraints for AI data centers.
Company announcements
Company disclosures and calendar updates have their own source dates. They do not revalidate every supplier role in this sector.
Market map
AI data-center growth is ultimately an electrical-infrastructure build. New compute capacity needs generation, utility interconnection, substations, large power transformers, switchgear, busway, backup power, cooling, and skilled contractors. Project timing is frequently determined by the slowest of these layers rather than by server availability.
Constraint Alpha separates equipment suppliers from power developers and integrators. Transformer factories and qualified high-voltage equipment may have multi-year lead times; turbines and onsite generation can relieve one constraint while creating fuel, permitting, emissions, or service dependencies; liquid cooling and power distribution determine how much compute fits inside a site.
The directory uses backlog, capacity expansion, utility approvals, customer commitments, and official product evidence as validation signals. It does not infer an AI revenue percentage from generic data-center language. Each record states whether the evidence is verified, sourced, or still a hypothesis and identifies the risk that could normalize the bottleneck.
Source-backed research
Versioned notes keep public evidence and member-only interpretation separate while preserving one canonical source.
Vantage said it secured more than 1 GW of Heron Link manufacturing capacity for hyperscale campuses. The agreement specifies a power-electronics path from medium voltage to 800 VDC but does not establish installed or energized megawatts.
Vertiv's 2.3 MW CoolChip coolant distribution unit qualified as NVIDIA DSX Ready, while NVIDIA launched DSX Ready to qualify power and cooling products against applicable AI-factory reference-design requirements.
GE Vernova disclosed a Chesterfield 400 kV substation project and a first-stage permit application for Blue Energy's Texas gas-plus-nuclear project. Both add project-level evidence beyond the July results.

Public preview
Examples are sampled across supply-chain layers; ordering is not a ranking. Each date records the company’s supplier-role review, not a new review of its financials or investment thesis. The sector date above does not mean every company was reviewed together. Scores, thesis, risks and full evidence remain in the Atlas.

Questions
It varies by location and project: generation availability, interconnection, transformers, switchgear, permitting, cooling, or electrical labor can each set the schedule.
They validate demand, control interconnection and construction execution, and provide supply-chain context even when they are not pure-play equipment suppliers.
Backlog growth, capacity sold ahead, named data-center awards, utility approvals, customer prepayments, and margin-supported pricing are stronger than generic AI marketing.
