The Trouble with Transformers

- U.S. faces a chronic shortage of electricity transformers due to surging demand from EVs and AI data centers, causing years-long delays and soaring prices, highlighting systemic grid infrastructure issues.
- The bottleneck stems from a lack of electrical steel (GOES), with only one U.S. producer (Cleveland-Cliffs), deindustrialization, and complex supply chains resistant to investment due to high costs and regulatory uncertainty.
- In 2023, the DOE attempted to ban GOES by raising efficiency standards to promote amorphous metal cores, but backtracked after union opposition, further chilling investment without resolving the shortage.
- Tariffs on steel and copper aimed at boosting domestic production instead increased costs and incentivized offshore processing, failing to close supply deficits (10% for distribution transformers, 30% for large power transformers in 2025).
- Innovations like Hertha Metals' low-carbon steel process and solid-state transformers (SSTs) offer efficiency and control improvements, but policy failures—such as lack of design standardization and misaligned regulatory mandates—hinder solutions.
