The global solid state transformer market size was valued at USD 123.2 million in 2023 and is projected to be worth USD 137.0 million in 2024 and reach USD 303.3 million by 2032, exhibiting a CAGR of 10.4% during the forecast period. The Asia Pacific dominated the solid state transformer market  with a share of 35.47% in 2023.

The global impact of COVID-19 has been unprecedented and staggering, with solid state transformer witnessing a negative impact on demand across all regions amid the pandemic. Based on our analysis, the global market exhibited a negative growth of -10.3% in 2020 as compared to the average year-on-year growth during 2017-2019. The rise in CAGR is attributable to this market’s demand and growth, returning to pre-pandemic levels once the pandemic is over.

Solid state transformer (SST), also known as a smart transformer, is a modern network device that integrates different power electronic converter stages with low or high-frequency transformers. SST delivers several benefits, such as they are efficient in utilization, highly reliable and robust, and is inexpensive as compared to traditional transformers. Furthermore, they reduce supply reliability and grid losses and safeguard the load from power disruptions. SST allows voltage transformation from Direct Current (DC) to Alternate Current (AC), AC to DC, and also DC to DC on various voltage levels. They are widely used in applications that enable a smooth conversion between AC and DC and help in voltage conversion. An SST is a prime enabler of uni-directional or bi-directional power flow with autonomous distributed and control intelligence by communications.

The COVID-19 pandemic has heavily impacted the global smart transformer industry; most of the companies/industries have become non-operational. The lockdown imposed in different regions hit the operations of several power distribution companies, which led to the decline in the demand for transformers across sectors. Renewable energy generation is the largest smart transformer application, which is severely affected during the pandemic. The negative effect of the pandemic on renewable energy generation has led to the delay in solid-state transformer project construction. Thus, this has a severe impact on various renewable project commissioning.

Solid State Transformer Market Trends

Rise in Number of Electric Vehicles to Enhance Market Growth

An increase in the production of electric vehicles offers growth opportunity for the market players as several countries, including India, China, Germany and the U.S., and others, are already deploying and encouraging the production of electric vehicles. Thus, the increase in demand for electric vehicles further boosts the development of electric charging stations, creating ample opportunities for the SST market. Furthermore, several electric vehicle initiatives across the globe are expected to enhance the industry outlook. For instance, in July 2021, the U.S. utility public service electric and gas company (PSE&G) partnered with Landis+Gyr for electric vehicles initiatives. PSE&G will be investing USD 1 billion to help customers improve their energy efficiency, USD 700 million in smart meters, and electric vehicles initiatives.

Solid State Transformer Market Growth  Factors

Modernization of Aging Power Distribution Infrastructure to Boost Market Size

The upgrade of aging power distribution systems is expected to drive the market growth of SST. The growing demand for intelligent and modernized power distribution infrastructure is likely to create ample opportunities for the market. In addition, government mandates to augment grid efficiency are propelling the adoption of smart transformers across various utility and energy sectors. Also, the market is expected to grow, owing to the advantages provided by SST. SST provides several benefits such as efficient power transmission, AC to DC conversion, and bidirectional power flow.

In June 2021, Snohomish County PUD announced to make electric system improvements in their existing substations. The PUD has work scheduled on many substations, including automation upgrades, equipment replacement, and standard maintenance. In addition, the PUD plans to replace their existing aging poles, assess and treat thousands of poles, and replace miles of aging underground cable.

Growing Adoption of Non-Conventional and Renewable Energy to Propel Industry Growth

Major economic countries are promoting several initiatives to enhance the part of renewable energy in their energy equity. Renewable energy benefits human well-being and general welfare in ways that go beyond GDP. Increasing the amount of renewables in the global energy mix by doubling raises global GDP by 2030 by up to 1.1%, or USD 1.3 trillion services as well as fossil fuels. Several countries are expanding the adoption of renewable energy generating in their total electricity output to reduce their reliance on coal-based electricity generation. Traditional transformers are replaced by these transformers in the renewable energy zone owing to the smart transformer design and safety aspects. Several government policies across the globe are helping initiate the usage of renewable energy in their industrial sectors. For instance, the government of the U.S. has targets to lower the greenhouse gas emission to 50-52% by 2030 and try to end the GHG emission by 2035 due to the usage of fossil fuels for power generation. Furthermore, various advantages delivered by SST, such as smart transformer efficiency, bidirectional power flow, and AC to DC conversion, are estimated to boost the market outlook.


High Cost of Product to Restrain Market Growth

One of the key market restraints is the high cost associated with these transformers. Hence, acceptance of smart transformers is low in underdeveloped and developing regions across the world.

In modern times, advanced and high powered transformers are equipped with streamlined technology, which makes it more expensive compared to typical transformers.  In addition, SSTs have performance limitations associated with their reliability and are not much commercialized. These factors are estimated to hinder the global market growth during the forecast period.

Solid-state transformers have a high implementation cost, limiting the market expansion. Furthermore, solid-state transformers adoption is likely to lower significantly in undeveloped and underdeveloped nations. Solid-state transformers are seen as a critical enabler for the development of upcoming electric power systems. As a result, the price is likely to fall in the future, owing to proactive government activities and increased product knowledge. The market growth is expected to be further hampered by the lack of understanding of the application of semiconductor transformers in various applications.

Solid State Transformer Market Segmentation Analysis

By Voltage Level Analysis

HV/MV Segment Witnesses Significant Growth Due to its Highest Adoption Rate

Based on voltage level, the market is primarily bifurcated into MV/LV and HV/MV. The HV/MV segment dominates the market and is projected to hold a significant share in the market. A major application of SSTs adopted in HV/MV level is in offshore wind turbines for HVDC/MVAC configuration. In this application, the lower weight or volume ratio of SSTs as compared to other passive transformers is a major feature that makes these transformers economically attractive.

The MV/LV segment is expected to grow at a significant rate during the forecast period. The growth is attributed to the rising demand for electric vehicles across the globe. The increasing demand for electric vehicles is primarily supported by growing government investments in electric vehicle charging infrastructures. Hence, growth in EVs further boosts the development of electric charging stations and thus surges the demand for MV/LV solid-state transformer.
