In the last year Airports Company South Africa (ACSA) has unveiled three solar-powered airports across the country, the first on the African continent to harness solar power. 

By the end of this year three more regional airports will join the green initiative by launching solar power plants, According to CNN

The state-owned ACSA told CNN over email that it is committed to reducing the pressure on South Africa's constrained power grid by around 50%.

This is because the solar farms currently supply approximately 45% of the airport's power requirement. The remaining 55% is drawn from the national grid.

"The long-term plan is to have the airports generate their own energy," says ACSA corporate affairs senior manager, Senzeni Ndebele.

The company intends to "greenify" all its airports and achieve carbon neutrality by 2025, Ndebele explains.
