US power grid upgrade stalls amid critical shortage of 1800s-era transformers

By PulseAugur Editorial · [1 sources] ·

The United States faces a critical shortage of large power transformers, essential for managing electricity transmission and distribution. These transformers, some weighing as much as 400 tons, are manufactured using a process dating back to the 1800s, and their production is hampered by limited global supply chains for key components like grain-oriented electrical steel. The demand for these transformers has nearly tripled for generator step-up units and more than doubled for off-ramp units between 2019 and 2025, leading to delivery times exceeding three years and significant cost increases. AI

IMPACT The shortage of power transformers could slow the expansion of AI data centers, which require substantial amounts of electricity.

    America’s grid upgrade hinges on a 400-ton machine designed in the 1800s — and just one U.S. mill makes the special steel inside it

    Between 2019 and 2025, demand for generator step-up transformers, those that connect power plants to the transmission grid, nearly tripled.
