HV/EHV power transformers, materials and services
BOTTLENECKGrain-oriented steel scarcity and 128-144 week lead times give Siemens Energy pricing power.
High-voltage transformers (69 kV to 1,200 kV) and their full supply chain including materials, repairs, and logistics. These are the most supply-constrained grid components for new AI load. OEMs and refurbishers hold pricing power with 128-144 week lead times and scarce grain-oriented steel feedstock.
Electromagnetic devices stepping voltage across the range 69 kV to 1,200 kV (GSU, network/autotransformers, substation step-down), plus the critical materials, repair services, and logistics sub-supply chain.
What the evidence shows
Major players like ABB, Siemens, GE, and Toshiba dominate the market.
