The global oil immersed three phase shunt reactor market size was valued USD 1.1 billion in 2023 and is estimated to grow at a CAGR of 7.1% from 2024 to 2032. As per the growing trend towards higher energy demand, the requirement for increased energy efficiency across electricity transmission networks is on the rise, and this translates into growth for the market too. Moreover, there are increasing investments across several nations towards improving and replacing older power infrastructure, and this too is supportive of growth of shunt reactor industry.

In addition, the intensifying shift toward oil-immersed reactors offering better insulation and cooling is evident while electric grids are being boosted for a higher voltage level. As the transmission lines are extended in order to support the rising integration of renewable energy, shunt reactors help in maintaining voltage stability at the endpoints while reducing reactive power loss. Yet the current oil-based reactors that are in use have some environmental issues, and the volatility in oil prices is proving to be a hurdle to the growth of the market.
