A shortage of utility-ready buildings and electrical equipment is leaving billions of dollars in GPU hardware unused as the U.S. artificial intelligence buildout hits a power wall. The lead time for generator step-up transformers exceeded 160 weeks in the first quarter of 2026, while high-voltage circuit breaker lead times rose to 125 weeks from 77 weeks in 2023. This gap between rapid chip delivery and multi-year electrical construction has left neocloud provider Nscale with only 25,000 operational GPUs as of Aug 31, despite having 461,000 contracted.

Microsoft CEO Satya Nadella warned that a lack of “warm shells”—empty buildings near large power feeds—could result in piles of chips sitting idle without power. To counter the deficit, OpenAI is lobbying the U.S. government for 100 GW of additional power generation annually. Meanwhile, GE Vernova reported its gas equipment backlog grew to 116 GW in one quarter, with some turbines not expected to arrive until 2031. SoftBank-controlled SB Energy, which is developing an Ohio site for OpenAI, has shifted its IPO timeline to December or possibly 2027.
