MARKET DRIVERS & OPPORTUNITIES

Growing Outlook of Digitalization in Transformers

The integration of digital technologies, such as IoT-enabled sensors and real-time monitoring systems, is transforming the global transformer market. Digital transformers are designed to improve efficiency, reliability, and maintenance processes, supporting the increasing demand for smart grid solutions. For instance, field trials of companies such as Prolec and Ubicquia’s smart transformers across North America have demonstrated their ability to provide real-time insights into transformer health and performance. In 2023, Prolec and Ubicquia introduced smart transformers with UbiGrid™, a monitoring platform that delivers real-time data and analytics to optimize operations and reduce downtime.

The Transformer 4.0 project also illustrates the role of digitalization in power transformers. It uses the Digital Twin (DT) concept to create a virtual version of the physical transformer, enhancing design, manufacturing, and maintenance processes. With AI and optimization tools, the project focuses on condition monitoring, predictive maintenance, and performance analysis throughout the transformer’s lifecycle. These developments reflect the growing focus on digitalization to meet the evolving needs of energy systems.

Rising Power Consumption Across the Globe

The increasing demand for electricity due to rapid industrialization and urbanization is driving the growth of the global transformer market. Investments in power infrastructure, particularly in developing economies, present significant growth opportunities. The BRICS nations—Brazil, Russia, India, China, and South Africa—experienced a notable surge in electricity consumption, with an overall increase of 6%. Among these, China and India saw the highest growth, with China’s consumption rising by 6.9% and India’s by 6.7%. This significant uptick in demand is reflective of the rapid industrialization and urbanization in these countries, which are placing increasing pressure on their power grids. These developments create a sustained need for transformers to support the expanding electricity networks, ensuring that the infrastructure can keep up with the heightened demand.

INDUSTRY RESTRAINTS

High Initial Costs

The high initial investment required for transformer manufacturing, installation, and maintenance poses a challenge in the transformer market, especially for smaller utilities and organizations in emerging markets. One major factor contributing to the high costs is the rising price of raw materials. Copper and grain-oriented electrical steel (GOES), two key materials used in transformer manufacturing, have experienced significant price increases. Copper prices have risen by nearly 40% since the pandemic, while GOES prices have nearly doubled. These materials constitute a substantial portion of the manufacturing cost, directly impacting the overall price of transformers.

SEGMENTATION INSIGHTS

INSIGHTS BY TYPE

The global transformer market is broadly segmented into distribution transformers, power transformers, and specialty transformers, each catering to distinct applications within power systems. Among these, distribution transformers held the largest revenue share. Their dominance is attributed to their extensive use in power distribution networks, where they step down high-voltage electricity from transmission lines to levels suitable for residential, commercial, and industrial end-users. The increasing demand for electricity in urban and rural areas, coupled with ongoing electrification projects in developing regions, continues to drive the widespread adoption of distribution transformers. Additionally, the modernization of aging distribution infrastructure in developed economies is further boosting the demand for efficient and reliable distribution transformers.

Power transformers, which are critical for high-voltage energy transmission over long distances, also account for a substantial share of the transformer market. Their demand is particularly fueled by the growing integration of renewable energy projects, such as wind and solar farms, into national grids. These transformers play a pivotal role in connecting renewable energy sources to the transmission network, ensuring efficient and stable power delivery. The global push towards decarbonization and the expansion of cross-border electricity trade is also contributing to the rising demand for power transformers with high-capacity ratings and improved efficiency.

Segmentation by Type

INSIGHTS BY VOLTAGE

The global transformer market by voltage is segmented into low voltage, medium voltage, and high voltage. Medium-voltage transformers held the largest share in 2023, mainly due to their use in industrial and commercial settings. These transformers are commonly found in manufacturing, construction, and commercial buildings, where they ensure a steady power supply. Furthermore, low-voltage transformers are mainly used in residential areas and small businesses. They deliver electricity at safe voltage levels for homes, offices, and small commercial spaces. The demand for these transformers is growing with urbanization and the increase in household energy use. Also, high-voltage transformers are used for long-distance power transmission and large energy projects. They help transmit electricity efficiently from power plants to distant locations. Their demand is increasing due to renewable energy projects and the need for expanded power transmission networks.

Segmentation by Voltage

• Low Voltage
• Medium Voltage

INSIGHTS BY INSULATION

The liquid-immersed insulation segment holds the largest share of the global transformer market in 2023. These transformers are widely used in utility-scale power distribution and transmission systems due to their higher efficiency and superior cooling capabilities. Liquid insulation, typically mineral oil or synthetic alternatives, effectively dissipates heat, allowing these transformers to handle larger loads and operate under high-stress conditions. Their robust performance makes them suitable for industrial facilities, power plants, and renewable energy installations where reliability is critical.

Furthermore, dry-type transformers are gaining popularity in specific applications due to their enhanced safety features and lower maintenance requirements in the global transformer market. Unlike liquid-immersed transformers, dry-type transformers use air or solid insulation, eliminating the risk of oil leaks and fire hazards. These transformers are increasingly used in environments where fire safety and environmental concerns are priorities, such as commercial buildings, residential complexes, and sensitive indoor facilities like hospitals and data centers. Additionally, their low maintenance needs and ability to withstand harsh conditions make them appealing for certain industrial and urban settings.
