Key Market Drivers

As businesses undergo digital transformations, data centers are at the heart of modern infrastructure. Data centers are experiencing exponential growth as industries demand uninterrupted, high-performance computing and storage capabilities. This, in turn, places significant pressure on power distribution systems. Data center substations, which convert high-voltage electricity to levels suitable for data centers, are critical to ensuring the smooth and efficient functioning of these facilities.

A growing reliance on digital services, including cloud applications, social media, and video streaming platforms, has led to an increase in global data traffic. This surge is boosting the demand for data centers and, consequently, for data center substations, which provide the power stability required for these high-demand environments.

The Role of MV/LV Transformers

Within the data center substation infrastructure, MV/LV transformers hold the largest market share. In 2025, they are projected to account for 48.6% of total market revenue, and their dominance is expected to persist as data center workloads continue to increase. These transformers are indispensable for voltage regulation, ensuring that power is efficiently transferred and preventing disruptions that could lead to data loss or downtime.

Their adaptability to fluctuating loads and their ability to support redundancy systems make them a key component in ensuring operational resilience. As data centers evolve into hyperscale and colocation facilities, the demand for reliable and scalable transformer systems will remain critical.

Voltage Demands and Technological Evolution

The 33kV to 110kV voltage segment will lead the market, capturing 44.2% of the market share in 2025. This range of voltage is ideal for large-scale data centers that require both high power and scalability to support future expansions. The ability of these substations to efficiently transmit power with minimal losses ensures they are an optimal choice for growing data centers, particularly in regions experiencing a boom in cloud-based solutions.

At the same time, the growing adoption of smart grid technologies and digital substations is revolutionizing the market. Companies such as Hitachi ABB Power Grids are investing heavily in advanced substation technologies that integrate digital solutions to improve power management and efficiency. These innovations are designed to enhance reliability and enable data centers to better handle fluctuating renewable energy sources, including solar and wind power.

Regional Insights

The United States is set to remain the largest market for data center substations, accounting for 24.6% of the market share by 2025. With its advanced IT infrastructure and a growing number of hyperscale data centers, the U.S. continues to drive the demand for efficient power solutions. Similarly, Germany is witnessing growth in the European market due to its strong industrial base and push toward renewable energy.

In Asia-Pacific, countries like India and China are emerging as significant contributors to the growth of the market, thanks to their increasing digitalization efforts and the establishment of vast data center networks. India, in particular, is expected to experience a 10.3% CAGR from 2025 to 2035, spurred by government initiatives such as Digital India, which aims to enhance digital infrastructure across the country.

The Shift Toward Green and Smart Infrastructure

As the world becomes more conscious of sustainability, data centers are facing growing pressure to reduce their carbon footprints. This has led to a surge in demand for green technologies within data center substations. The shift toward renewable energy solutions, coupled with government regulations aimed at improving energy efficiency, is encouraging investment in smart substations that can integrate clean energy sources and optimize power usage.

For example, CtrlS in India is deploying a gas-insulated substation (GIS) in Mumbai, designed to scale up to 700 MW, making it one of the most advanced substations in the region. Such developments are expected to foster greater market growth, especially in countries like Brazil, Mexico, and Thailand, where digitalization and smart infrastructure adoption are accelerating.
