The upgraded features have resulted in lower operating costs, less downtime, and more efficiency. The technologies have given operators advanced functionality, including real-time monitoring, predictive maintenance, and remote optimization.
- According to the International Energy Agency (IEA), the total global investment spending in electricity networks stood at USD 332 billion in 2022. Furthermore, to support the net-zero trajectory, the annual investment is expected to more than triple to USD 871 billion annually in the decade preceding 2050. Thus, investments and upgradation of the T&D infrastructure are expected to continue in the coming years, thereby aiding the demand for transformer monitoring systems.
- As a result, manufacturers in this market are continuously innovating to develop cutting-edge software solutions that not only enhance operational efficiency and safety but also align with sustainability goals. Such factors are expected to aid market growth during the forecast period.


Asia-Pacific Expected to Dominate the Market


- Asia-Pacific is the largest energy consumer globally. As of 2022, according to the Statistical Review of World Energy, the region generated nearly 14,546.4 TWh of electricity, accounting for nearly 49.8% of the global generation. During 2012-2022, electricity generation registered a steady CAGR of 4.6%. Additionally, in 2022, electricity generation increased by 4% Y-o-Y. The rising electricity demand in Asia-Pacific is expected to impact the usage of transformers in the region significantly, thus driving the demand for transformer monitoring systems.
- The rising integration of renewable energy from massive utility-scale renewable energy farms in countries such as China and India, the electrification of industries and buildings, and the growth of data centers all contribute to a significant increase in electricity consumption. As the population and urbanization in the region grow, the demand for electricity is also expected to increase, driving the need for transformers to handle higher voltages, and power levels will also increase. Additionally, integrating renewable energy sources like wind and solar into the grid will require new transformers to control the variable and decentralized energy they produce.
- As electricity demand across China has grown steadily, the country has invested heavily in its T&D infrastructure to satiate the burgeoning energy demand. For instance, in January 2023, the State Grid Corporation of China announced plans to invest nearly USD 77 billion in transmission infrastructure and energy storage systems during 2023, up by nearly 4.0% Y-o-Y.
- India is also one of the largest electricity consumers globally. India is witnessing massive infrastructure development in the energy, transportation, and real estate sectors. These projects require a robust electrical grid system, including power transformers, to support the growing energy demand and ensure reliable power supply to various infrastructural facilities. In addition, the country's power grid has become older and is in dire need of modernization. With the increasing power load and rising integration of variable generation assets such as solar panels and wind turbines, grid stability has become a significant issue. Hence, the government, including state and federal electric utilities, has been investing heavily in the upgrade and modernization of the grid.
- For instance, according to the Powergrid Corporation of India (PGCIL), the country's largest transmission utility, the country plans to invest USD 34.2 billion to set up an interstate transmission network (ISTS), primarily to accommodate and transmit renewable energy. According to the state utility, the plan envisions investments of up to USD 17.1 trillion from 2026 to 2027. According to the Power Ministry, the country has already approved 23 ISTS projects for green energy evacuation at a total cost of USD 1.9 billion during FY 2022. As of November 2022, transmission projects worth nearly USD 7.2 billion were approved.
- Such developments are expected to increase the usage of transformers, thus driving the transformer monitoring system market during the forecast period.
