How Is The Growth Of AI Data Centers Driving The Demand For Power Transformers?

The rapid expansion of AI Compute infrastructure is transforming global energy demand. The expansion of hyperscale AI data centers to support large language models, autonomous systems, and high-performance computing (HPC) is leading to the surge in electricity consumption. This, in turn, requires the installation of power transformers which handle grid interconnection, voltage regulation and load balancing, thereby increasing their widespread applicability across data center power systems.

According to International Energy Agency (IEA), China and the U.S. are estimated as the most significant regions for data center electricity consumption, accounting for nearly 80% of global growth by 2030. The consumption is anticipated to increase by around 240 TWh (up 130%) in the U.S., compared to the 2024 level. In China, it increases by around 175 TWH (up 170%) for China and 45 TWh (up 70%) for Europe.

In April 2026, Enphase Energy, Inc. announced the development of its IQ Solid-State Transformer (IQ SST) which is a next-generation distributed power platform designed specifically for AI data centers.

This replaces traditional centralized power conversion with a modular “supercluster” design, where each 1.25 MW rack integrates hundreds of semiconductor-based power modules working together to deliver highly efficient energy distribution.

How Do Raw Material Availability And Long Lead Times Restrain The Power Transformer Market?

Fluctuations in raw material availability and supply chain disruptions negatively impact the power transformer market by creating an inconsistent supply base. Rising geopolitical tensions, trade tariffs (One Big Beautiful Bill (OBBBA) in the U.S.), and material shortages affect export dynamics, leading to increased production costs for transformer manufacturers.

Additionally, the shortage grain-oriented electrical steel (GOES) which represents 20% of the transformer cost, followed by rising lead times is leading to a supply chain crisis in the U.S. power sector.

For instance, the production capability of GOES limited only to Cleveland Cliffs (U.S.) constrains supply flexibility and impacts transformer production timelines amid growing demand from grid modernization and electrification initiatives. This is expanding average lead times for power transformers and specialized units up to 60 months for North America and Europe and 12 months for Asia Pacific causing a significant backlog of power transformer orders. This further contributes to higher project expenses and hinders market development.

To address the challenge, stakeholders are transitioning towards amorphous core transformers which use non-crystalline metal alloys, resulting in up to 70–80% reduction in no-load losses, and lower carbon footprint.

In February 2026, Proterial, Ltd. announced the establishment of a new Metglas amorphous metal material production facility in Andhra Pradesh (India), to cater rising demand for energy-efficient transformer components. The plant with an initial production capacity of 30,000 tons per year is scheduled to begin operations in October 2026.
In August 2025, Klöckner & Co is expanded its electrical steel processing capacity in the U.S. to address rising demand of cold-rolled grain-oriented (CRGO) electrical steel for transformer production and modernization of the aging U.S. power grid. The company established a new production and service center that will increase processing of cold-rolled grain-oriented (CRGO) electrical steel, including slitting and transformer core manufacturing.

How Are Digitalization And Cybersecurity Trends Impacting The Power Transformer Market?

The adoption of digitalization and cybersecurity measures in power systems is emerging as a notable trend in the market. The demand for smart and digitally enabled power transformers featuring real-time monitoring, remote diagnostics, and secure communication within modern grid architectures is transforming the market.

Integration of power transformers into digital substations and connected control environments is viewed as data-rich components within broader cyber-physical systems. Cyberattacks on the grid impact power transformers causing incorrect readings, operational disruptions, equipment damage, or large-scale power outages. The malfunction results in forced constant turning on/off which creates an artificial demand for power. This causes the power transformers to trip, leading to blackouts.

To mitigate these operational disruptions, power transformer units are installed with sensors, condition monitoring systems, and communication interfaces. These interfaces enable predictive maintenance, improve operational efficiency and robust cybersecurity providing defense against unauthorized access, data manipulation, and communication-based attacks.

The energy infrastructure of Poland witnessed a failed cyberattack targeted in January 2026 which disrupted communication links between renewable energy installations and power distribution operators.

In April 2026, Hitachi Energy invested USD 10 million to establish a Power Electronics Center of Competence in Cary, North Carolina (U.S.). The center is developed as a global hub for cybersecurity and advanced grid technologies and large power transformer development.
