Solid State Transformers Market Size & Share 2026-2035

Solid State Transformers Market Size

The global solid state transformers market was valued at USD 200.5 million in 2025. The market is expected to grow from USD 278 million in 2026 to USD 968.2 million in 2031 & USD 2.7 billion in 2035, at a CAGR of 28.8% during the forecast period according to the latest report published by Global Market Insights Inc.

The growth of the solid-state transformer market is attributed to the modernization of aging power grid infrastructure, increasing integration of renewable energy sources and distributed energy resources, rapid expansion of high-power electric vehicle charging infrastructure, growing electrification across transportation and industrial sectors, and continuous advancements in wide-bandgap power semiconductor technologies that enable compact, efficient, and intelligent power conversion systems.

The expansion of SST is heavily attributed to upgrade and modernization efforts for older electricity grid, transmitting and distributing, globally. Utilities have been slowly yet steadily migrating toward smart grids and digitizing their infrastructures. These grids demand sophisticated power conversion technologies, real-time voltage regulation, bidirectional power flow and enhanced grid resilience. Traditional electrical transformers don't possess ability to facilitate DER, micro grid and smart distribution technologies due to their design, on the other hand, SST utilizes advanced power electronics and digitized controls. For instance, government backed initiative supporting this trend is the U.S. Department of Energy (DOE) publication of its 2024 Distribution Transformer Demand report, prepared by the National Renewable Energy Laboratory (NREL). The report highlights that growing electricity demand, aging transformer fleets, electrification, and grid modernization are increasing the need for advanced transformer technologies capable of supporting future grid requirements.^{[1]Distribution Transformer Demand Report,energy.gov}

Fast charging infrastructure for EVs, renewable energy installations, and battery energy storage (BESS) solutions are some other factors pushing the solid state transformers market. For utilities with growing shares of solar PV and wind energy, and other distributed generation units, old technology-based traditional transformers are unable to manage bidirectional flow of power and have voltage issues as well as a wide range of voltage variation and fluctuating loads. With their abilities to provide an interface with DC sources and facilitate conversion to AC, these new-generation transformers can also support power quality management, provide enhanced regulation to overcome voltage variations and fluctuations, and help manage charging from both grid and battery-powered EVs, facilitating integration of ultra-fast chargers. For instance, the National Renewable Energy Laboratory (NREL) published a 2025 Cooperative Research and Development (CRADA) report demonstrating medium-voltage solid-state transformers for EV corridor charging, solar-plus-storage applications, and distributed energy resource integration under evolving grid regulations such as FERC Order 2222. The report identifies SSTs as a key enabling technology for modern utility networks and advanced energy systems.^{[2]National Renewable Energy Laboratory, research-hub.nlr.gov}

Steady growth in the solid-state transformers market has been driven by constant advancements in wide-bandgap (WBG) power semiconductors (SiC, GaN devices) which allow switching of power at much higher frequencies, offer greatly reduced power losses, superior thermal performance and much higher power density than traditional silicon power electronics, leading to more compact, efficient and smarter SSTs in smart grids, renewable energy systems, electrified rail lines, industrial operations, electric vehicles, among other power electronics applications. Moreover, rapid developments in medium voltage power electronics and digital grid control would boost SST commercialization efforts and help speed the overall transformation to a modern grid.
