The oil-immersed segment dominated the three-phase shunt reactor market in 2024 with a 69.3% share, driven by its superior cooling efficiency, long service life, and reliability in high-voltage applications. Oil-immersed reactors are widely adopted in transmission and distribution systems to stabilize voltage and compensate for reactive power. Their compact design and ability to handle fluctuating loads make them ideal for grid infrastructure and renewable integration projects. The air-core segment is growing steadily due to its lightweight structure and suitability for indoor and offshore installations where oil-based systems are restricted.
- For instance, Hitachi Energy supplied a 500 kV variable oil-immersed shunt reactor for a wind-power integration project in Uzbekistan, ensuring continuous reactive power compensation and improving system stability during high wind variability
By Product
The fixed shunt reactor segment held the largest market share of 63.8% in 2024, owing to its wide use in transmission networks for continuous voltage regulation and power factor correction. Fixed reactors are preferred for their low maintenance needs, cost efficiency, and stable performance under varying load conditions. Growing electricity demand and grid expansion in developing economies further enhance their deployment. The variable shunt reactor segment is gaining traction in smart grid systems as utilities seek flexible voltage control solutions that adapt to renewable generation variability.
- For instance, GE Vernova has received orders from the Power Grid Corporation of India (PGCIL) for over 70 units of 765 kV class shunt reactors and transformers to be used in transmission projects within India’s renewable energy corridors
By End Use
The electric utility segment accounted for the largest share of 72.1% in 2024, supported by large-scale investments in power transmission and distribution networks. Utilities deploy three-phase shunt reactors to mitigate line charging currents, reduce energy losses, and ensure grid stability under dynamic load conditions. The renewable energy segment is also expanding rapidly, driven by increased wind and solar integration into national grids. As fluctuating renewable outputs create reactive power imbalances, demand for adjustable and efficient shunt reactors continues to rise across solar farms and wind power substations.
Key Growth Drivers
Expansion of Power Transmission Networks
Rising demand for electricity and expanding high-voltage transmission infrastructure drive the adoption of three-phase shunt reactors. Utilities use these reactors to stabilize voltage, improve reactive power compensation, and minimize transmission losses across long-distance lines. Ongoing grid modernization and the construction of new substations further strengthen market growth. Government initiatives to enhance grid reliability and reduce power fluctuations are fueling global investments in advanced shunt reactor technologies.
- For instance, Hyosung Heavy Industries provided 400 kV 100 MVAr shunt reactors for the Energinet grid expansion project at Denmark’s Kasso substation. These reactors are intended to improve voltage regulation in high-voltage transmission networks by balancing reactive power from line capacitance.
Integration of Renewable Energy Sources
The rapid integration of renewable energy, particularly wind and solar, is boosting demand for three-phase shunt reactors. These reactors help maintain voltage stability in power networks affected by fluctuating renewable output. Countries expanding their renewable capacity are deploying shunt reactors to ensure efficient grid synchronization and energy flow control. As renewable projects connect to long transmission lines, the need for voltage regulation equipment continues to rise, enhancing market adoption.
- For instance, Hitachi developed a 275 kV air-core shunt reactor installed at the Nishi-Kameda Switching Station in Hokkaido as part of the Hokkaido–Tohoku interconnection line reinforcement project.
Modernization of Aging Electrical Infrastructure
Aging transmission and distribution networks are being upgraded to improve efficiency and reliability, creating opportunities for three-phase shunt reactor installations. Many countries are investing in replacing outdated grid components with advanced, energy-efficient solutions. Shunt reactors are essential for minimizing reactive power and improving power factor in modern systems. Continuous upgrades in smart grid and substation automation technologies are further supporting the deployment of digital and compact reactor systems.
Key Trends & Opportunities

Utilities are adopting intelligent shunt reactors integrated with IoT sensors and automated control systems. These digital solutions enable real-time performance monitoring, predictive maintenance, and optimized voltage regulation. Growing investment in smart grid technology and demand for remote operation capabilities are driving this trend. Manufacturers focusing on digital twin technology and AI-based grid control solutions are expected to gain a competitive edge.
- For instance, SGB SMIT introduced a 420 kV digitally controlled shunt reactor equipped with Siemens Sensformer 2.0 sensors capable of transmitting load, temperature, and oil moisture data every 60 seconds. The system integrates with SCADA platforms to predict insulation degradation 20 days in advance, significantly reducing maintenance downtime and enhancing operational reliability.
Rising Investments in HVDC and UHV Transmission Lines
The expansion of high-voltage direct current (HVDC) and ultra-high-voltage (UHV) transmission projects is creating major opportunities for the three-phase shunt reactor market. These reactors play a key role in managing reactive power in long-distance and cross-border power transmission. Rapid development of intercontinental grid connections and offshore wind power networks further supports their deployment. The trend is particularly strong in Asia-Pacific, Europe, and the Middle East.
- For instance, Fuji Electric has manufactured numerous shunt reactors for use in Japan’s 500 kV transmission networks and other high-voltage systems to compensate for reactive power on long transmission lines and cable systems.
Key Challenges
High Installation and Maintenance Costs
The complex design and installation requirements of three-phase shunt reactors result in significant initial investment. Additional costs arise from maintenance, insulation testing, and oil management in high-voltage environments. These financial barriers often delay project implementation in developing countries. Manufacturers face pressure to deliver cost-efficient, compact, and low-loss reactor systems to ensure better economic feasibility for utilities.
Technical Limitations in High-Voltage Applications
Three-phase shunt reactors face performance challenges such as insulation failures, thermal stress, and magnetic losses under fluctuating grid loads.
