Solid State Transformer Market Report

The demand for solid-state transformers (SST) is expected to increase due to rising vehicle production. SSTs are used in the automotive industry to enable improved energy management, EV charging, and drivetrain performance. Furthermore, global vehicle production is increasing because of economic growth and higher disposable incomes, leading to greater demand for personal and commercial vehicles. According to the data of the International Organization of Motor Vehicle Manufacturers (OICA), in 2023 global vehicle production was recorded at 95.11 million units, which registers a growth compared to 2022. Increasing vehicle production increases the demand for original equipment manufacturer brake systems. Also, the rising rate of renewable power generation can be considered a driving factor for the solid-state transformer market. SSTs are popular in renewable power due to their high efficiency, compact design, and ability to manage voltage variations. Advanced control capabilities boost the integration of solar and wind, improving grid stability and energy distribution, supporting the solid-state transformer market growth.

Additionally, as per the data of the Indian Energy Agency, by 2024, wind and solar PV will exceed hydropower in electricity generation. In 2025, renewables will top coal as the largest source. Wind and solar PV are expected to surpass nuclear power in 2025 and 2026, respectively. It is expected that renewable energy will hold over 42% of global electricity in 2028, with wind and solar PV doubling to 25%, thus making renewable power generation a lucrative market and strengthening the solid-state transformer market outlook. The growing deployment of AC-DC converters alongside renewable energy systems further supports efficient power conversion and grid integration.

Solid State Transformers play a key role in railway systems to provide efficiency, reliability, and flexibility in power management. The new SST technology utilizes power electronics that can handle any change in voltage and frequency, thus allowing the integration of intermittent renewable energy sources and advanced train control systems. Thus, railway network expansion boosts solid-state transformer market growth, increasing demand for railway freight, improving connectivity, drives economic development. As per the data of the European Rail Supply Industry Association, the global rail market is expected to experience an annual growth of 3% by 2027 and is expected to reach US$ 233 billion between 2025 and 2027, contributing to a positive, solid state transformer market forecast.

Furthermore, as per the data of the International Energy Agency, the global demand for transport is growing fast. Given present trends, passenger and freight activity will more than double by 2050. Rail transportation is highly energy efficient, carrying 8% of the world's passengers and 7% of global freight with only 2% of total energy demand. The major manufacturers are improving efficiency and thermal performance, along with more effective communication capabilities for smart grid integration, to make this innovation stand apart, not only in being operationally more efficient but in contributing to the shift toward greener rail transport and influencing overall solid-state transformer market size expansion.

• SSTs are being developed for fast charging stations.
• SSTs support the development of smart grids by enabling better communication and control.
• Advances in semiconductor technology like SiC and GaN, are leading to smaller, lighter, and more efficient SSTs, reflecting emerging solid state transformer market trends.

The problem of compatibility in (Solid State Transformer) SSTs is essentially the problem of making the advanced power transformer operate satisfactorily with existing systems and parts in which it will be installed. SST uses modern technology, such as power electronics, to better convert electricity than conventional transformers. Since they operate differently, though, problems occur when one tries to connect them to older equipment or infrastructure. SST will pose a challenge to ensure that they are able to handle multiple power levels, connect seamlessly with various types of energy sources, and maintain reliable performance in real-world conditions. This aspect of compatibility will need to be overcome before SSTs can find their place within the power grids or any other applications, a key consideration in solid-state transformer industry analysis. The integration of devices such as a current transformer within existing electrical infrastructure can further add to system compatibility considerations.

Furthermore, the challenge in maximizing the conversion efficiency for these transformers the electricity in its forms gets converted with little energy loss in an SST. This helps in saving energy and reducing costs. The efficiency of SSTs is tricky in achieving very high levels because the heat generated and the quality of the components used may lead to energy waste within the conversion process. Such an outcome may prohibit even the otherwise positive effects of SSTs regarding support for renewable energy sources or enhanced grid reliability. This is to surmount the challenge and eventually make the SSTs a practicable and efficacious option in modern power systems, shaping future solid-state transformer market analysis.

In October 2021, GE-Prolec Transformers, Inc., a subsidiary of a 50/50 joint venture between GE and Xignux, a Mexico-based private company, announced that it had completed the acquisition of SPX Corporation's SPX Transformer Solutions business. The contract purchase price was US$ 645 million, subject to a net working capital adjustment and other typical adjustments. The acquisition of SPX Transformer Solutions, which was known for its Waukesha® transformers, services, and components, allowed Prolec GE to comprehensively serve the growing Americas market with a broader portfolio of innovative and sustainable solutions for the delivery of electrical energy.

In March 2021, Hitachi ABB Power Grids, a global technology leader, and Nanyang Technological University, Singapore (NTU Singapore), a leading research-intensive university, worked together to advance developments in Solid State Transformer (SST) technology. The project was led by the Energy Research Institute @ NTU (ERI@N) and was supported by the National Research Foundation, Singapore (NRF). The project was part of the Singapore Government’s flagship Energy Grid 2.0 initiative aimed at shaping the next-generation grid system and transforming how energy was managed by consolidating multiple energy sources into a single intelligent network that was more efficient, sustainable, and resilient, positively impacting the solid state transformer market share across advanced energy infrastructure projects. The development of advanced grid architectures also complements innovations in DC switchgear for enhanced power distribution and protection.

Asia Pacific can be considered a promising market because of the rising production of commercial vehicles and cars. Due to this rising production, various countries in the Asia Pacific have been named as automotive hubs driven by both local consumption and export opportunities. Also, as per the data of the International Organization of Motor Vehicle Manufacturers, four out of five top global vehicle manufacturers belong to Asia Pacific countries. As per the data, a total of 49.2 million units were produced in the Asia Pacific out of 94 million global production. The top four countries include China, which produced 30 million units, followed by Japan, which produced a total of 8.9 million units.
