Aircraft operate on a unique 400 Hz electrical frequency, necessitating specialized conversion equipment at airports. The 400 Hertz Ground Power Market was valued at USD 2.55 Billion in 2025 and is expected to reach USD 5 Billion by 2035. These systems—available in mobile, fixed, and containerized units—allow aircraft to shut down their auxiliary power units (APUs), significantly reducing fuel consumption, noise, and carbon emissions at the terminal.The primary growth driver in 2026 is the global push for "Green Airports" and the modernization of ground support equipment (GSE). Leading companies like JBT Corporation and Cavotec are integrating IoT sensors into their ground power units (GPUs) to provide real-time monitoring of energy usage and predictive maintenance alerts. With the Asia-Pacific region rapidly expanding its airport capacity to meet rising air traffic demand, the 400 Hz market is seeing significant investment in modular, high-efficiency solid-state converters that can withstand extreme runway environments.
