Expanding Power Infrastructure Driving Demand for Grid Support Equipment

As installed power capacity continues to grow across regions, the complexity of managing large-scale transmission networks is also increasing, shaping the shunt reactor market outlook. Expansions in generation, especially from renewable and distributed sources, are pushing grid operators to invest in equipment that can ensure stability, efficiency, and power quality across long distances. Shunt reactors are gaining wider acceptance for their role in absorbing reactive power, improving voltage regulation, and supporting overall grid performance. Their ability to manage line charging currents in high-voltage networks makes them essential as new substations and transmission corridors are added. Variable types, in particular, offer adaptability to fluctuating load conditions, making them well-suited for modern grids with dynamic operating profiles. As more capacity is connected to the system, the need for flexible, space-efficient solutions that can be integrated without major redesigns is growing. These factors are contributing to the broader adoption of shunt reactors in both new installations and grid upgrade programs. As of January 2025, the total installed power capacity stands at 466.26 GW.

Increased Adoption of High-Voltage Reactive Power Equipment

As countries expand renewable capacity, the need for advanced grid-stabilizing equipment is rising. Variable shunt reactors are becoming essential for managing reactive power in high-voltage systems, especially where wind and solar sources are being integrated. These reactors help maintain voltage stability and reduce transmission losses, improving overall system performance. Their growing use reflects a shift toward flexible grid solutions that can support clean energy goals without compromising reliability or efficiency. As per the shunt reactor market forecast, adoption is also accelerating in regions with emerging renewable infrastructure, where grid modernization is a key part of national energy strategies. For example, in October 2024, Hitachi Energy delivered a 500 kV variable shunt reactor for Uzbekistan’s Dzhankeldy wind farm, supporting grid stability as the country scales up renewables. The reactor, made in China, is the first of its kind for Uzbekistan. It supports a 500 MW onshore wind facility developed by ACWA Power, expected to generate 1.65 Million MWh annually and cut carbon emissions by 750 tons, helping meet Uzbekistan’s 2030 clean energy goals.
