A 1.2 MW solar installation at Douala International Airport in Cameroon has entered service, under efforts to cut CO 2 emissions produced by aircraft during ground operations.
The government of Cameroon funded the purchase of airport gate electric equipment, which will be connected to the new solar park. A similar project is planned for Garoua International Airport.
Conventional gate operations involve the use of auxiliary power units (APUs) or diesel-driven ground power units (GPUs) to provide pre-conditioned air and electricity to aircraft on the ground.
With the new solar power capability, Douala International aims to eliminate at least 2,575 tonnes of CO₂ annually from more than 5,100 flights, based on the more than 5.5 million kWh per year it expects to generate.
