Market Dynamics

China Solid State Transformer Market Drivers

Rising Demand for Electric Vehicles

China is the world's largest Electric Vehicle (E.V.) market, and the government wants 50% of new car sales to be electric by 2035. SSTs can help build efficient, dependable charging stations to meet this demand.

In 2019, State Grid Corporation of China and BYD built an SST-based electric bus charging station in Guangzhou. A 200kW SST reduced charging equipment size and efficiency to 94%. The charging station became cheaper and easier to deploy. A 2020 Tsinghua University research team created an SST-based EV charging system. A 250kW SST reduced charging equipment size and efficiency to 98.8%. Researchers said the technology fully charged a BYD electric bus in 30 minutes.

China Solid State Transformer Market Restraints

High Cost

Solid-state transformers cost more than traditional transformers. Power electronics and complex control systems make SSTs more expensive than traditional transformers. In low-margin businesses, this cost premium may prevent uptake. SSTs cost more than standard chargers but enhance E.V. charging station efficiency and reliability. BYD and State Grid Corporation of China launched a USD 1.5 million SST-based electric bus charging station in Guangzhou in 2019. Traditional charging stations cost roughly USD 200,000. Charging infrastructure operators may struggle to scale SST-based systems due to this cost premium.

China Solid State Transformer Market Opportunities

Increasing Demand for Renewable Energy

It is an ambitious goal for China to have 35% of its electricity originate from renewable sources by 2030. This has substantially increased the use of wind and solar energy, fueling China's need for SSTs. In Qinghai Province in 2019, the China Electric Power Research Institute installed a 110kV SST to facilitate the integration of wind power into the grid. The SST provided a more efficient and dependable solution for power transmission than conventional transformers, resulting in decreased power losses and improved power quality. The preponderance of China's electricity transmission is managed by the State Grid Corporation of China, which has also invested in developing SSTs for various applications. The company has developed a 10kV SST for wind power integration and a 35kV SST for city power systems.

Regional Analysis

China is the largest market for transporting and distributing power (T&D) worldwide. Due to its plans to cut carbon emissions and commitment to green development, it is anticipated to purchase a significant amount of smart grid equipment. 8.11 trillion kilowatt-hours (KWh) of energy were used in China's power industry in 2021 from all sources combined. Various energy sources power the nation, including coal, natural gas, nuclear energy, wind, water, biofuels, and the sun. China has the largest industrial sector; thus, as industrial demands have increased quickly, so have the nation's energy needs.

Due to the volume of electricity projects it implements, China is quickly becoming a powerhouse in the Asian region. China has assumed a prominent role in the development of renewable energy through a large number of solar installations. In addition, the China State Railway Group unveiled a new plan to increase the network's length to almost 200,000 km by the end of 2035. The 70,000km high-speed railway network is another goal of the plan. The railway line connecting Kathmandu, Nepal, and Lhasa, Tibet, has also been constructed by China. From 70GW to 120GW of nuclear energy is planned for development in China. These infrastructure improvements offer numerous chances for the solid-state transformer market to expand. Businesses are investing more funds in distribution networks and concentrating on smart grids. In China, demand for Solid state transformers is anticipated to rise over the next years as a result of this.
