Power Transformer Market by Power Rating (Small, Medium, Large), Cooling Type (Oil-cooled, Air-cooled), Phase (Single Phase, Three Phase), End Use (Utilities, Residential & Commercial, Industrial), and Region - Global Forecast to 2030

The global power transformer market is projected to grow from USD 30.38 billion in 2025 to USD 41.62 billion by 2030, at a CAGR of 6.5% during the forecast period. This upward trajectory is primarily driven by the rising global demand for electricity, fueled by rapid industrialization, expanding manufacturing activities, and ongoing infrastructure development across developed and emerging economies. The industrial sector, in particular, is a major contributor to this demand, as modern facilities require robust and efficient power distribution systems, where power transformers are crucial. In addition to industrial applications, the market is experiencing growing demand from the commercial, service, and residential sectors. Commercial operations increasingly rely on uninterrupted power to maintain productivity, while the service sectors, including healthcare, education, and hospitality, are seeing a surge in electricity consumption to support digital infrastructure and service delivery. Meanwhile, population growth and urbanization drive the need for a reliable and consistent power supply in residential areas. Together, these trends underscore the critical role of power transformers in ensuring stable energy distribution across diverse end-use sectors.

“By power rating, large (above 600 MVA) is anticipated to be the fastest-growing segment from 2025 to 2030”

The large (above 600 MVA) segment is expected to exhibit the highest CAGR from 2025 to 2030. The global shift toward renewable energy and the deployment of utility-scale wind and solar projects result in the rising demand for high-capacity transmission systems capable of efficiently handling high voltages over long distances, making large transformers essential. In rapidly industrializing and urbanizing regions, expanding and modernizing power grids to support rising energy consumption further accelerates the need for these high-capacity units. Additionally, the increasing trend of cross-border grid interconnections aimed at improving power supply reliability and stability boosts the demand for large power transformers. In developed economies, efforts to replace aging infrastructure with advanced, energy-efficient systems also contribute to this growth. These developments position large power transformers as critical enablers of resilient, future-ready energy networks, supporting traditional and renewable power systems.

“Based on phase type, the three-phase transformers segment is projected to hold the largest market share in 2030”

The three-phase transformer segment is expected to hold the largest market share in 2030. It is driven by its widespread use across commercial, industrial, and utility sectors that require high-capacity solutions for efficient power transmission and distribution. These transformers are well-suited for high-load applications, offering superior efficiency, stable power flow, and reduced energy losses. These factors make transformers essential in settings with substantial and continuous power demands. As global energy consumption rises alongside expanding industrial operations and infrastructure development, the demand for reliable and high-performance transformers continues to grow. Moreover, three-phase transformers are critical in integrating renewable energy sources into the grid, supporting the global shift toward cleaner and more sustainable energy systems. Their ability to manage larger electrical loads efficiently and their versatility across various high-demand sectors solidify their position as the leading segment in the power transformer market over the forecast period.

“North America is expected to be the second fastest-growing region in the power transformer market during the forecast period”

North America is projected to be the second fastest-growing region in the power transformer market during the forecast period due to a strong focus on upgrading aging grid infrastructure, integrating renewable energy sources, and meeting increasing electricity demand driven by data centers, electric vehicles, and industrial automation. The proactive approach to modernizing transmission and distribution networks and government initiatives supporting clean energy transitions significantly boosts the demand for high-efficiency power transformers. In addition, the presence of major industry players, technological advancements, and regulatory policies emphasizing energy reliability and grid resilience further contribute to the robust growth in the power transformer market during the forecast period.
