Air Core Fixed Shunt Reactor Market Size - By Phase, By End Use, Analysis, Share, & Forecast, 2025 - 2034

Air Core Fixed Shunt Reactor Market Size

The global air core fixed shunt reactor market was estimated at USD 497 million in 2024 and is estimated to reach the value of USD 966.2 million by 2034, growing at a CAGR of 7.1% from 2025 to 2034. This demand is attributed to the need for voltage regulation and reactive power compensation in high-voltage transmission networks.
 

The use of air core reactors for effective management of voltage fluctuations posed by the inclusion of wind and solar energy into power systems is required. For instance, in April 2025, India plans to increase its solar power capacity, in addition to existing renewables, to 2.3 TW by 2025 and 5.8 TW by 2030, significantly raising its energy generation goals.
 

Air core reactors provide significant advantages over oil-immersed variants, including reduced maintenance requirements, higher reliability, and improved environmental safety. Recent advances in insulation materials and cooling systems have increased the efficacy and operational life of these reactors.
 

Increasing investment in substations and modernization of transformers in developed nations aids in providing further assistance in air core fixed shunt reactor market development. On the other hand, raw material price volatility, industry rivalry, and stringent performance regulations in addition to safety compliant rules restrict unrestrained development for manufacturers.
 

The Trump administration tariffs, especially the 25% tariffs on steel and aluminum, are likely to have a big influence on the air-core fixed shunt reactor industry. These reactors, which are crucial for power system voltage regulation, depend significantly upon high-quality aluminum conductors. The higher tariffs drive up material prices, resulting in increased production costs and longer procurement times. As such, utilities could experience grid infrastructure project timelines slippage and reassess investments in such reactors, holding back grid modernization initiatives.
