Power Supply
Power Supply
We supply power to aircraft (electricity, air-conditioning, and compressed air) as well as design, construct, and manage the operation of power supply facilities for aircraft.
While we supply electricity, air-conditioning, and compressed air to power aircraft, our methods can be split in two broad types.
We also use our power-supply equipment to install charging facilities for electric vehicles to provide electricity.
SYSTEMS
Fixed Equipment
This refers to equipment on the ground that supply aircraft with their required power and air-conditioning. At present, fixed Ground Power Units (GPUs) are the main form of facilities to supply power. This system involves installing a power plant with power receiving and distribution facilities and thermal energy supply facilities within the airport, receiving commercial power from an electricity company, and supplying electricity and chilled/warm water to the equipment (*1) at the parking apron. The apron equipment converts the electricity for aircraft use and generates heated and cooled air using the chilled/warm water, supplying each to the aircraft.

Mobile Equipment
This refers to vehicles known as mobile GPUs that supply electricity, heated and cooled air, and compressed air at parking aprons that do not have fixed equipment.
They play an important role at locations such as parking aprons lacking in fixed equipment and small local airports.
Why does power need to be supplied to aircraft?
Aircraft can generate the necessary power and heated/cooled air while parked at an airport apron by using a small gas-turbine known as an Auxiliary Power Unit (APU). This method works in the same way a car engine provides power and heated/cooled air.
However, as APUs are gas turbine engines, they generate large amounts of exhaust fumes and noise when burning aviation fuel.
Conversely, our GPUs supply electricity for aircraft and heated/cooled air using electricity from electric companies, resulting in no issues with pollution as well as being superior to APUs in terms of cost-effectiveness.
- Advantages of using GPUs
-
- ❶ Less than 1/10th of APU CO2 emissions
- ❷ Reduced consumption of aviation fuel
- ❸ Reduced noise while stationed in parking aprons
Charging Equipment
We have installed charging facilities for electric vehicles (electric cars and electric ground support equipment) at Haneda Airport and Kansai International Airport for our customers to use, which also help to contribute to reduced CO2 emissions from vehicles at airports.
By using GPUs, our company will continue to enhance their capabilities in the future, both in terms of environmental impact and cost, and will work towards the preservation of our planet’s environment.
