Gaurab Chakrabarti — the 1,120-day transformer wait runs through one US steel line

A chemical-plant builder traces the grid bottleneck to a single material: grain-oriented electrical steel. Only Cleveland-Cliffs makes it in the US, covering roughly 12-20% of US need by DOE's estimate, while step-up transformer lead times have grown from under 500 days to more than 1,120. China's Baosteel needed a decade to close the same gap, which is a physical reason the AI power build stays short of equipment.

Every AI data center needs power, and every power plant needs a step-up transformer to connect to the grid. If you ordered one in 2021, it arrived in under 500 days. Today it takes more than 1,120 days. A large transformer core is made of grain-oriented electrical steel that
