01 Expansion of Fixed Gate Electrification and Aircraft Ground Energy Systems Ground power infrastructure is increasingly shifting from standalone mobile equipment toward fixed gate-based systems that provide aircraft with electricity during turnaround operations. Fixed electrical ground power can reduce aircraft auxiliary power unit use while also improving gate-level energy efficiency and reducing local emissions and noise. This structural change is increasing the role of GPUs within broader airport gate-electrification infrastructure rather than treating them solely as mobile ground-support equipment. In 2025, ICAO reported an APU-substitution initiative at Paris Charles de Gaulle and Milan Malpensa airports that used fixed external power and pre-conditioned air systems, reducing APU operating time by more than 3,000 hours and cutting 1,259 tonnes of CO₂ emissions.
02 Integration of Renewable Energy and Energy Storage With Ground Power Systems Ground power systems are increasingly being connected with renewable electricity generation and energy-storage technologies to improve the sustainability and energy resilience of aircraft turnaround operations. Airport projects are combining GPUs with solar generation, battery storage, and airport electrical networks, creating more flexible approaches to supplying aircraft at the gate. This development is changing GPU infrastructure from a standalone power source into part of an integrated airport energy system. In 2025, ICAO reported a passenger-bridge project combining photovoltaic panels with an electric ground power unit using battery technology to supply 400 Hz electricity to aircraft during turnaround operations.
01 Growth in Aircraft Turnaround Activity and Airport Capacity The ground power unit market is supported by increasing aircraft movements and airport capacity requirements, which raise the need for reliable electrical power during aircraft turnaround operations. GPUs allow aircraft systems to receive ground-based electricity without continuously operating onboard auxiliary power units, supporting efficient gate operations. Expansion of airport infrastructure and continued growth in air connectivity therefore create a broader operational base for ground power equipment.
01 High Infrastructure and Installation Costs for Electrified Gate Systems Ground power deployment can require substantial investment in electrical distribution, fixed equipment, cabling, passenger-bridge modifications, and associated airport infrastructure. These requirements can make modernization more difficult for smaller airports and operators with constrained capital budgets. The financial burden becomes particularly significant when GPU upgrades must be coordinated with wider electrical infrastructure improvements.
01 Expansion of GPU Use in Regional and Smaller Airports A distinct opportunity exists in extending reliable aircraft ground-power infrastructure to regional and smaller airports that have historically had fewer advanced gate-support systems. Deploying scalable mobile or modular GPU solutions can provide aircraft with ground electricity without requiring the extensive fixed infrastructure associated with large hub airports. This creates commercial potential in airports seeking to improve operational capability without undertaking complete gate reconstruction.
01 Ensuring Reliable Power Delivery Across Diverse Aircraft and Airport Systems GPU systems must deliver stable electrical output while remaining compatible with different aircraft types, airport electrical networks, operating environments, and safety requirements. Variations in aircraft turnaround procedures and gate infrastructure can complicate equipment standardization and system integration. Maintaining reliable power quality while coordinating GPU operation with other airport energy systems therefore remains a key technical and operational challenge.
February 2026 ITW GSE highlighted the deployment of eight ITW GSE 2400 Power Coils and four Power Share units at Leeds Bradford Airport, strengthening fixed gate power infrastructure and supporting the airport's transition toward lower-emission aircraft ground operations.
February 2026 Exeter Airport reported the successful demonstration of a hybrid hydrogen-diesel ground power unit alongside hydrogen-powered ground support equipment under the Zero Carbon Turn project. The trial evaluated hydrogen technologies in live airside operations and generated operational and safety evidence for future airport deployment.
August 2025 Leeds Bradford Airport introduced eight Fixed Electrical Ground Power units that allow aircraft to use fixed electrical power while parked. The deployment was designed to reduce reliance on aircraft auxiliary power units and diesel-powered mobile GPUs and forms part of the airport's Noise Action Plan.
Late 2025: AEME GSE deployed more than 100 S400-A bridge-mounted solid-state ground power units at Hohhot Shengle International Airport in China. The installation established 400 Hz aircraft ground power coverage across airport stands and supported the new airport's operational launch.
