Power transformer shortage slows AI data center construction in 2026
CNews reports on an acute shortage of power transformers in 2026. The equipment was invented back in the 19th century, yet it remains the heart of every power grid. The shortage is hitting the fast-growing AI industry hard: without new transformers, data centers can't be connected to the grid, which puts leading tech companies' plans to bring new compute online at risk.

The rapid rise of artificial intelligence has run into an unexpected obstacle: an acute shortage of power transformers in 2026, CNews reports. These devices were invented back in the 19th century, yet they remain the heart of every power grid.
Why did an old technology become a bottleneck?
The publication points to a paradox: artificial intelligence, one of today's most advanced technologies, is held back by a shortage of equipment whose design hasn't fundamentally changed in decades. Every large new power consumer, data centers included, needs transformers to connect to the grid. Without them, new compute physically can't go into operation, even if the servers and chips themselves are already delivered and paid for.
How does this threaten tech companies' plans?
According to CNews, the widespread transformer shortage in 2026 puts leading tech companies' plans to bring new compute online at risk. The companies in question are building or planning data centers for training and running AI models. These are exactly the facilities that need grid connections at a scale requiring dozens or even hundreds of power transformers.
What does it mean?
The AI boom is constrained not only by shortages of chips and electricity, which get most of the attention, but also by a more mundane bottleneck: manufacturing transformers, a 19th-century technology. As long as the industry's production capacity can't keep pace with data center construction, some announced projects risk delays, no matter how many GPUs have already been bought.
