Aircraft Ground Power Units

Aircraft Ground Power Units (GPUs) are essential pieces of ground support equipment used to supply electrical power to aircraft while they are parked on the ground. Instead of relying on the aircraft’s onboard auxiliary power unit (APU), GPUs provide a safe, cost-effective, and fuel-efficient power source during maintenance, boarding, and pre-flight operations.

Airports around the world, including Toronto Pearson International Airport and Heathrow Airport, rely heavily on GPUs to ensure aircraft systems remain operational while minimizing fuel consumption and emissions. An Aircraft Ground Power Unit is a mobile or fixed device that supplies electrical power to an aircraft when its engines are shut down.
