A domestic shortage of electrical equipment such as transformers and switchgear is forcing the US to rely on Chinese imports, delaying data center construction
Bloomberg
Context & Ripple Effects
The data-center buildout had already widened from a compute race into a physical-infrastructure squeeze: earlier shortages of data-center parts, sites and power showed that construction schedules were constrained well beyond chips and servers.
This report identifies electrical equipment as a binding link in that chain. It aligns with subsequent coverage of transformer order lead times stretching into years and developers seeking on-site generation while grid connections remain slow.
First-order effects
US data-center developers face longer and less predictable construction schedules when transformers and switchgear cannot be sourced domestically; importing from China becomes a near-term procurement option.
Domestic electrical-equipment suppliers gain leverage over scarce output, while developers must treat power-delivery hardware—not just grid interconnection—as a critical-path dependency.
Second-order effects
Delays in equipment delivery compound grid-access constraints, encouraging some developers to redesign projects around aeroderivative turbines and diesel backup generation rather than wait for conventional utility service.
Reliance on Chinese equipment exposes project schedules and costs to cross-border sourcing conditions, increasing the value of qualified alternative suppliers and standardized, readily available designs.
Third-order effects
If shortages persist, AI infrastructure investment will increasingly be governed by the pace of power-equipment manufacturing and grid buildout, rather than by demand for compute alone.
The mismatch strengthens the case for domestic supply-chain expansion, but it also raises a policy trade-off: efforts to reduce import dependence could further constrain near-term data-center deployment unless new capacity arrives quickly.
The trend: AI infrastructure is shifting from a semiconductor-and-server expansion story to a broader industrial-capacity race centered on power equipment, grid access and construction execution.
@baoshaoshan Its like no one in Washington realized Chinese companies dominate entire supply chains for rare earths, magnets, and manufacturing of key inputs for the entire energy supply chain....

“There's only going to be one winner on AI and that's probably going to be the US or China,” said Trump. Well, there's no US winning without China, as our deep dive on the electrical infrastructure behind the trillion-dollar data center spend shows. 🎁🔗 https://www.bloomberg.com/.…
Almost half of US data centers planned for 2026 are expected to be delayed or canceled. One big reason is the shortage of electrical equipment, such as transformers, switchgear and batteries. US doesn't have manufacturing capacity, forcing it to rely on imports. — 🎁🔗 https://…
