Market Segmentation:

Segmentation 1: by Application

  • Smart Grid
  • Renewable Power Integration
  • Traction Locomotive
  • EV Charging Station
  • Others

Based on applications, the global solid-state transformer market is expected to be dominated by renewable power integration applications. This is followed by the EV charging stations segment, which is expected to account for the second-largest share in the solid-state transformer market due to increasing demand for electric vehicles and the building and construction of EV charging stations across the globe.

Segmentation 2: by Product Type

  • Power Transformer
  • Distribution Transformer
  • Traction Transformer

Based on product types, the distribution transformer segment is estimated to capture the highest market share during the period 2026 to 2031. This type of transformer is increasingly used in power distribution networks and in renewable power integration. In addition, the replacement of aged power distribution systems in the countries such as Germany, India, the U.S., the U.K., and other countries is further expected to fuel the demand for distribution transformers during the forecast period.

Segmentation 3: by Region

  • North America - U.S., Canada, and Mexico
  • Europe - Germany, France, Italy, Spain, and Rest-of-Europe
  • China
  • U.K.
  • Asia-Pacific - India, Japan, Australia, South Korea, and Rest-of-Asia-Pacific
  • Middle East and Africa - Saudi Arabia, South Africa, and Rest-of-Middle East & Africa
  • South America - Brazil, Rest-of-South America

Asia-Pacific is anticipated to generate the highest revenue of $61.0 million in 2025. The region is experiencing an increase in renewable power generation, distributed generation, and sales of electric vehicles. Therefore, conventional transformer technology will be challenged by solid-state transformer (SST) alternatives in renewable power transmission and distribution infrastructures. The Asia-Pacific region is anticipated to grow at a faster rate compared to any other region.

Recent Developments in the Global Solid-State Transformer Market

  • In January 2022, Eaton Corporation acquired Royal Power Solutions (EV component producer) for $600 million. Under the agreement between the Department of Energy (DOE) and Eaton Corporation, Eaton would develop and demonstrate electric vehicle charging infrastructure (EVCI). To support this charging infrastructure, Eaton would develop a solid-state transformer. This acquisition strengthened the position of eMobility company in the EV sector.
  • In March 2021, Hitachi Energy (formerly Hitachi ABB Power Grids) collaborated with Nanyang Technological University (NTU) Singapore. This collaboration aimed at advancing developments in solid-state transformer (SST) technology. This project is supported by the National Research Foundation, Singapore (NRF). This would enhance the product portfolio of the company and its presence in the solid-state transformer market.
  • In December 2019, ERMCO, Inc partnered with SP Energy Networks (a U.K. electricity network operator). Through this partnership, ERMCO would provide smart transformer solutions to LV Engine project. This project would monitor or demonstrate how smart transformers can efficiently manage energy, and then they would deliver smarter grids with lower carbon emissions.
  • In December 2021, Eaton Corporation signed an agreement with the Department of Energy (DOE). This agreement or award was aimed at developing low-cost fast-charging infrastructure, solid-state transformers, and modular chargers in a three-year timeframe (2022-2025). This would strengthen the position of the company in the solid-state transformer market globally.

  • Solid-state transformers are the primary building blocks of the smart grid infrastructure. Such a transformer can transfer power bidirectionally and scale down and scale up voltages as per the application. The companies that manufacture conventional transformers are taking an interest in the R&D of solid-state transformers to fulfill the future demand from smart grid infrastructure.
  • Solid-state transformers, with the inclusion of communication capability among components used in the power system infrastructure, can be referred to as the smart transformer in the coming years. It will help power utilities in the measurement of demand and supply of electricity use. A solid-state transformer has various advantages over conventional transformers, including power factor correction, fault isolation, harmonic reduction, voltage sag and swell compensation, bidirectional power transfer, and others.

Impact of COVID-19

Due to the COVID-19 pandemic, research and development slowed down across many industries owing to the lack of funding, halted manufacturing activities, and components or raw material supply chain disruptions. In addition, a halt in the building and construction of renewable power infrastructure and smart grid projects has also been induced by COVID-19, which is resulted in a decrease in demand for transformer products and further affected R&D projects worldwide.
