Among excitation system applications, synchronous generator is expected to account for the largest market share of 68.9% in 2025. Synchronous generators remain the workhorse of centralized utility-scale and industrial power generation worldwide due to their enormous scale and high efficiency. Nearly all large thermal and hydroelectric power stations rely on synchronous machines to convert prime mover torque into electrical power.

The characteristic large size of utility generators, ranging from tens to hundreds of megawatts each, drives high excitation power demand to maintain synchronous speed under varying loads. Proper field excitation is critical for synchronous generators to produce smooth sinusoidal voltage waveforms in synchronization with the power system frequency. This ensures grid stability and power quality across transmission and distribution networks.

Moreover, synchronous generators can achieve efficiencies up to 99% due to synchronous operation with zero slip between the stator magnetic field and rotor. No other electric machine comes close to matching their immense power capacities or conversion efficiencies at utility scales. Their robust heavy-duty build also provides long operational lifetimes of 40 years or more. No other generation technology has so comprehensively dominated bulk power supply around the world for over a century.

While applications like renewable energy integration and distributed generation adopt other motor/generator types, the ubiquity and immense capacities of conventional centralized synchronous generator fleets will sustain their primacy in the excitation application segment. Even as the generation mix diversifies long-term, synchronous machines are projected to remain pivotal in Baseload, intermediate and peaking power plants that define baseload power systems for decades ahead. Synchronous excitation therefore comprises the lion's share of this excitation systems market portion.
