AI Ends at Power—Transformers and Silicon Steel Matter

A sheet of silicon steel, thinner than two A4 papers, is quietly holding back global AI giants. While engineers in Silicon Valley are still struggling to push the parameter limits of next-generation large models, an unexpected bottleneck has already emerged—not chips, not algorithms, but electricity. More precisely, it is the “heart” that delivers electricity safely

Global Transformer Shortage to Last Until 2029

The world is entering a prolonged phase where power transformer supply simply can’t keep up with demand. This isn’t a short-term demand spike. Instead, it’s a full-blown capacity, delivery, and labor crunch. Grid upgrades, generation growth, and surging data center loads are all falling behind schedule because of it. According to the Zhuifeng Trading Desk, analyst

The Silicon Steel Opportunity in U.S. Grid Expansion

Table of Contents 1. The Booming Demand for Silicon Steel Driven by U.S. Grid Expansion In recent years, the U.S. power system has faced three major challenges. These include aging infrastructure, surging electricity demand, and the urgent need to switch to cleaner energy. Grid expansion and upgrades have become essential to address these issues. 1.1

Rectangular Transformer Laminations

Table of Contents 1. Introduction In modern power systems, distribution transformers represent the final and most widely deployed link between electricity generation and end users. Unlike large transmission transformers, these units operate continuously—often 24/7—for decades in outdoor and demanding environments. From residential neighborhoods to industrial parks, their performance directly affects power stability, energy efficiency, and
