America's Power Grid Equipment Shortage Is Real: 80% of Large Transformers Are Now Imported

Electricity demand in the United States fell by roughly 1% between 2010 and 2020, according to figures cited by Fox News. LED lighting, efficient motors and stricter appliance standards absorbed the growth from new homes, factories and data centers, and then some. For a decade, the electric grid looked like a business with nowhere to go.

That assumption shaped everything utilities, manufacturers and steelmakers did next. Companies didn't invest in apprenticeships because there was no new capacity to staff. They didn't stockpile metallurgical expertise because nobody was ordering new equipment. They didn't recruit young workers into an industry whose main selling point was that it would never change.

Then demand changed. Since 2020, U.S. electricity consumption has climbed about 7%, reversing the prior decade's decline. Demand for large power transformers, the equipment that nearly all U.S. electricity passes through at some point, has surged 116% since 2019, according to Fox News.

The reasons are stacking up at once: the AI data center boom, reshoring of manufacturing, broader electrification of homes and vehicles, and utility efforts to harden aging grid infrastructure. All of it is landing on a supply chain that spent a generation shrinking.

The Numbers Behind the Shortage

Roughly 80% of the large power transformers installed in the U.S. are now imported, Fox News reported. The grain-oriented electrical steel used inside every one of them has only a single domestic producer left. Lead times for a standard power transformer now stretch to nearly two and a half years, and the larger units linking power plants to the grid take even longer.

Prices for transformers are up more than 77% since 2019. Meanwhile the equipment already in service is old: the average transformer on the American grid is 38 years old, and more than 70% of the existing fleet is past age 25. The country is trying to replace an aging equipment base and build a new one simultaneously, using a manufacturing pipeline it spent 20 years hollowing out.

Texas Is Already Feeling It

The strain isn't theoretical. Fox News reported that Texas Gov. Greg Abbott has effectively paused new data center hookups to the state's power grid pending a statewide grid audit, and separate Fox News reporting noted Texas has suspended power hookups for new AI data centers specifically over grid reliability concerns. A state with some of the country's most aggressive data center buildout is now hitting the brakes because the grid behind it can't keep pace.

Tech companies want to build AI infrastructure fast. Grid operators and state regulators are the ones who have to guarantee the lights stay on for everyone else, including homes and hospitals, while that build-out happens. Texas choosing caution over speed is a signal other states may face the same choice.

The Harder Problem Is People, Not Steel

Equipment shortages can theoretically be fixed with capital: build new steel mills, expand transformer factories, subsidize domestic production. Congress and the Trump administration have both signaled interest in reshoring critical manufacturing, and this is a textbook case for that argument.

But the workforce problem doesn't respond to money the same way. A worker who spent a decade watching an industry insist it would never grow again didn't train for a job that wasn't coming. Rebuilding metallurgical and electrical engineering expertise, and the trade schools and apprenticeship pipelines that produce it, takes years even after the funding and political will exist. You can expedite a factory. You can't expedite the decade of accumulated experience a skilled tradesman needs.

What's Unresolved

The Fox News piece doesn't address whether the Trump administration or Congress has committed specific funding or policy toward rebuilding domestic transformer manufacturing capacity, nor does it name which companies or unions are involved in any workforce rebuild effort. It's also unclear how many other states beyond Texas are weighing similar pauses on data center grid connections, or how utility regulators plan to prioritize scarce transformers between reshoring manufacturers, AI data centers and routine grid replacement needs.

With lead times near two and a half years and 70% of the existing transformer fleet already past age 25, the shortage isn't a temporary bottleneck. It's a structural gap between what the grid needs now and what the domestic supply chain can currently produce.
