The global excitation systems market is poised for steady expansion over the next decade, with the market expected to grow from approximately USD 3,402 million in 2025 to USD 6,305 million by 2035. This growth reflects a compound annual growth rate (CAGR) of 6.4% between 2025 and 2035. The market’s upward trajectory is being fueled by increased demand for reliable and efficient power generation systems across thermal, hydro, and renewable energy sectors. Excitation systems, which are critical for maintaining the stability and control of generators by regulating the field current, are gaining significant traction as global electricity consumption rises and energy infrastructure modernizes.
Industries are increasingly adopting excitation systems to support industrial automation and to ensure smooth operations of synchronous machines in complex power networks. Additionally, the growing integration of renewable energy sources into national grids is enhancing the need for advanced excitation systems that can stabilize grid voltage and frequency amidst intermittent energy input. The shift toward sustainable energy generation, especially in regions such as Asia-Pacific and Europe, is prompting utilities and independent power producers to upgrade or replace outdated excitation equipment with digital, real-time monitoring systems. This is creating a broader market base for both static and brushless excitation systems across multiple sectors.
