Cleveland-Cliffs controls a quiet bottleneck in the power-transformer buildout. Grain-oriented electrical steel gates every large transformer, and Cliffs' Butler Works in Pennsylvania is the only US facility qualified to make it. Transformer lead times already run about 36 months, and data center grid interconnections compress the queue further. The thesis breaks if domestic transformer capacity ramps meaningfully or the Defense Production Act reshuffles allocation; neither looks imminent. x.comÂ
Cleveland-Cliffs sets the price of grain-oriented electrical steel with zero US competition, and the AI buildout won't slow that demand. Per @Vaelis_X, its Butler Works plant is the only US producer of this steel for large power transformers, where it is about 25% of cost, with transformer lead times averaging 128 weeks and prices up 77% since 2019. x.comÂ
Scarcity across grid equipment, electrical steel, HBM, turbines and foundries leaves their suppliers with upside through 2028. The 2026-28 bottleneck scores are 94, 94, 93, 88 and 86 respectively; they measure constraints, not market size. The list covers Hitachi, Powell, TBEA, Nippon Steel, POSCO, Cleveland-Cliffs, Samsung, SK hynix, Micron, Howmet, TSMC, Intel and SMIC. Powell has the highest remaining upside at 7.5/10 with 3.2 risk; Intel scores 7.4 upside but 6.8 risk. x.comÂ
Cleveland-Cliffs is the biggest beneficiary. x.comÂ
Steel is the bottleneck behind AI's power bottleneck, and mill equipment makers like Danieli benefit most from the upgrade cycle it forces. Transformers need grain-oriented electrical steel, gas turbines need rotor forgings only a few forges can make, and power lines use steel-reinforced cable. About 70% of global blast-furnace capacity hits reinvestment deadlines before 2030, forcing mills to invest, sell or die after years of underinvestment. Danieli's 50% gain in a year is just the start. … Show more
American Superconductor, Cleveland-Cliffs and Preformed Line Products are critical US infrastructure compounders, not parabolic growers, backed by Defense Production Act support for domestic grid manufacturing. The action declared a national energy emergency over the grid supply chain, authorizing federal funding, purchase commitments and faster expansion. Hammond Power Solutions shows the demand: revenue of C$264M beat C$236.3M estimates and backlog rose 94.6%, a leading indicator. x.comÂ
