Power parts and the electron super‑cycle
What happened
Data‑center expansion for AI is running into shortages of transformers and other electrical components, a bottleneck that complicates new facility buildouts and colocation availability. That supply pressure is part of a broader ‘electron super‑cycle’ as energy demand for AI and data centers surges, driving capital into power and grid upgrades. Capacity and timeline risk for new low‑latency sites now includes electrical infrastructure, not just racks and silicon. (japantimes.co.jp) (markets.financialcontent.com)
Why it matters
Large, grid‑scale transformers and related substation gear are taking far longer to arrive than usual: delivery lead times have exceeded 100 weeks for several years and are currently running about 128 weeks (roughly 2.5 years) for big power transformers and about 144 weeks for generator‑step‑up units. (eepower.com) Manufacturers and market trackers report the shortage has pushed equipment prices sharply higher — industry writeups show transformer prices up roughly 60–80% versus 2020 — and that the scarcity is already causing project delays at scale, with reporting that nearly half of U.S. data centers planned this year face delays or cancellations and analysts estimating 30–50% of projects could be pushed out. (jzpelectric.com) (bloomberg.com) A transformer is the heavy electrical device that converts high‑voltage transmission power down to the lower voltages a data center uses, and switchgear is the set of circuit‑breaking and routing equipment that protects and directs that power; both are custom, material‑intensive assemblies that require long, specialized manufacture and therefore sit on the critical path for energizing a site. (eepower.com) The supply squeeze is colliding with already extreme colocation demand: vacancy in major markets is at historic lows and 90%‑plus of new capacity is pre‑committed, which means firms that need ultra‑low latency face two hard choices — pay steep premiums for power‑guaranteed space inside core hubs (adding cost) or move farther away into “frontier” regions where available megawatts exist but network distance (and therefore latency) rises. (jll.com) (datacenterknowledge.com) Responses on both sides of the stack are concrete and time‑bound: hyperscalers are buying or building energy assets and considering on‑site generation to bypass grid waitlists (for example, a major cloud buyer acquired an energy company and some providers are deploying gas‑turbine or microgrid solutions), while transformer OEMs are expanding U.S. capacity — but those factory builds take years (Eaton’s announced plant expansion targets 2027) and utility interconnection queues have ballooned (one market’s large‑load queue grew ~300% in 2025), so site‑energization risk will persist for the medium term.
